How to install Websphere MQ on Windows Host and get started ?
1. Ensure you have Admin access on Windows platform.
2. Open command prompt as admin, type HOSTNAME and hit the enter.
3. MQ Series full installation needs 900 MB of free disk space. So ensure we have it before you try. In cmd window type dir|find "free", it should give free bytes available on host.
4. Find if it is a 32 bit platform or 64 bit platform and check system type by typing systeminfo in cmd.
5. Download suitable version of MQ software (32/64 bit), from IBM portal.
6. Unzip IBM MQ Build downloaded.
7. Locate MQLaunch.exe and execute it.
8. In order to install MQ 7.0/1 you will need version 3.x Eclipse to be pre-installed on host. Otherwise Install it from MQinstallationsource/prereq/IES/setup.exe and then
9. Type DSPMQVER on cmd to confirm installation is successful. Version of MQ installed on host is printed.
Now in command prompt type the following:
1. CRTMQM <QMGRNAME 8 chars>, will create a Queue manager (QMGR).
2. DSPMQ -M <QMGRNAME>, will display the status of QMGR created.
3. STRMQM <QMGRNAME>, will start the QMGR.
4. RUNMQSC <QMGRNAME>, will get you into QMGR cotrol, where in you can further create other MQ objects and play around it.
2. Type AMQSPUT <QUEUENAME> <QMGQNAME> and hit the enter key. type messages one after the other and keep hitting enter after end of every message.
Example input:
msg1
msg2
msg3
msg4
..
AMQSPUT: is a sample MQ program (provided along with MQ Series software installation package) to put messages onto the business queue.
2. Type RUNMQSC <QMGRNAME>
3. Now type DISPLAY QLOCAL(<business queue created under QMGRNAME>) CURDEPTH
Here CURDEPTH property represents the number of meggages already on the queue.
4. Type END, to exit from QMGR control.
2. Type AMQSGET <QUEUENAME> <QMGRNAME> and hithe enter key.
Example output:
msg1
msg2
msg3
msg4
..
AMQSGET: is a sample MQ program to retrieve messages from the business queue (also known as local queue).
NOTE: Value between <> braces should have meaningful names for queue managers and queues. In real world JAVA/.NET/Mainframe applications will be on either side of MQ Server (QMGR) instead of AMQSPUT and AMQSGET programs.

SSL Certificate management in Websphere Application Server
We
should first understand why we need ssl communication and what is the
impact of not installing the certificates.
Earlier whenever we want to make any banking transaction (e.g.: depositing the money, with draw money, transfer money, etc), make a reservation for Air travel, etc… we used to visit the branches, stand in the queue and wait for our turn and complete the transaction. But, in present day with time constraint, busy world none of us wants to waste time being in queue. Thanks to the internet based applications which made every work possible with a finger click. But, always a question remains how about the security to these transactions on the internet??.
The JSSE (JAVA Secured Socket Extension) is a set of packages that enable secure Internet communications. It implements a Java technology version of Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. It includes functionality for data encryption, server authentication, message integrity & optional client authentication.
SSL configuration: SSL configuration help us in making secured communication between the application deployed inside the websphere and external client (browser) by encapsulating the data as required by JSSE. These certificates inside the websphere are mainly of 2 different types. They are as follows:-
(a) Self Signed certificates ( or Internal or Default Certificates)
(b) Signer Certificates (or Digital Certificates)
Self Signed Certificates: From websphere application server 6.1 onwards the self signed certificates are created automatically during the profile creation .i.e., whenever the profile is federated to cell self signed certificated are created automatically. The management of these self signed certificates is automatically taken care. The expiration of these certificates is monitored on a pre-defined schedule with notifications sent to system logs and email-sending capabilities. The certificates will be automatically replaced before expiration, by default, and, there will of course be a warning prior to the certificate replacement.
Signer Certificates: A signer certificate represents certificate and public key associated with some personal certificate. The signer certificate explicitly trusts connections made to or by the owner of the associated personal certificate. The signer certificate is typically made completely public by the owner of the personal certificate, but it’s up to the receiving entity to determine if it is a trusted signer prior to adding it to the trust store.
Following are the steps involved for installing the SSL signer certificates:-
1) **Invoke the ikeyman from the profiles bin directory.
2) In the IBM Key Management Utility, click on Key Database File and then New
3) Choose Key database type and select JKS. Give any name to keystore like Test_key.jks.
4) Click the Browse button and give location where we want to store keystore file.
5) Click OK. Enter a password and click OK.
6) Click Create then New Certificate Request to bring up the Create New Key and Certificate Request window.
7) Type a Key Label, Common Name, Organization, Locality, State, and select a Country. Select 1024 for Key Size.
8) Click on Key Database File and then Open. Locate the keystore file that you created when you generated the CSR. Type the password and click OK.
9) Select Signer Certificates from the pull-down list.
10) Click the button to Add…
11) Login to WAS console with the valid credentials and Expand “Security” link at left hand side pane.
12) Click on “SSL certificate and key management”.
13) Click on “SSL configurations” link.
14) Click on “Key stores and certificates” link.
15) Select the scope by clicking on CellDefaultTrustStore (or NodeDefaultTrustStore) link from the list.
16) Click on “Signer certificates” link.
17) Click on Add button.
18) Give alias name as “Test_Cert”.
19) Give filename as complete path of “Test_Cert.cer” on server.
20) Click apply and then OK and restart all the WAS server instances.

How to automate Thread Dumps in Websphere Application Server ?
WebSphere Application Server attempts to report
potentially hung threads using the hung thread detector. Depending on
how the hung thread detector policy is configured, a thread running for a
certain interval (default 10 minutes) might be reported as hung and a
WSVR0605W message is printed in the SystemOut.log file:
WSVR0605W: Thread <threadname> has been active for <time> and may be hung. There are <totalthreads> in total in the server that may be hung.By setting a WebSphere custom property, the hung thread detector will automatically generate a javacore, or print a thread dump in the native_stdout.log for Solaris and HP-UX, when a WSVR0605W message is written out to the SystemOut.log file. Javacores/thread dumps are needed for determining what code is running in the potentially hung thread, if the reported hung thread is blocked by other threads, and/or if bottlenecks exist in the JVM.
The com.ibm.websphere.threadmonitor.dump.java property was enabled in WebSphere Application Server V6.0.2.29, 6.1.0.19, 7.0, 8.0, 8.5 and later.
Set the com.ibm.websphere.threadmonitor.dump.java property to true. Where?
Detailed Steps:
1. Log on to the admin console of Deployment Manager (DMGR).
2. Go to Servers > Application Servers > server_name > Server Infrastructure > Administration > Custom Properties
3. Click New and add the following property:
Name: com.ibm.websphere.threadmonitor.dump.java
Value: true
4. Click Apply. Click OK and save the configuration changes.
5. Restart the Application Server for the changes to take effect.
Do the same with Node Agent:
- From the DMGR administrative console, click System Administration > Node Agents > nodeagent_name > Additional Properties > Administration Services > Additional Properties > Custom Properties
- Click New and add the following property:
Name: com.ibm.websphere.threadmonitor.dump.java
Value: true
- Click Apply. Click OK and save the configuration changes.
- Restart the Node Agent for the changes to take effect.

How to generate Thread Dumps manually in Websphere Application Server 7 and analyze?
Application Server is nothing but a Java process. And as you are aware Java language supports multi-threding concept. The class file (could be a POJO/Servlet/JSP) whichever receives the request will decide what method (also called as functions in other programming languages) of that class will handle the request. Once the appropriate method is engaged (to process the business logic/control commands), a thread id is assigned to it. In a similar fashion, many java threads will process in parallel thereby enabling multi-threading in Java on Websphere Application Server's JVM (server basically). In order to take a look at the objects (object is a variable in system memory which holds the end to end methods/variables being called for a particular java class) status currently the Heap memory allocated to JVM occupies we can generate a thread dump. A thread dump will detail the java methods currently under execution on a running JVM, and its execution time.
2. To identify the root cause of an application server hang/thread hangs.
3. To scrutinize the under-performing application server and suggest heap corrections or application performance issues with development team.
1. In Linux/Unix/AIX/HP-UX/Solaris platforms, use "kill -3 <PID>" to generate thread dumps from OS level.
2. You can do this from Websphere supplied wsadmin commands to generate one as well!
Navigate to Application server's profile_home bin directory and execute wsadmin command as shown below:
<WAS_HOME>\profiles\<profilename>\bin# ./wsadmin.sh -username XXX -password XXXX
$AdminControl invoke $JVMNAME dumpThreads
Ex: wsadmin> $AdminControl invoke Server1 dumpThreads
At wsadmin prompt use the above command with JVMNAME = application server name as it appears in logs folder for this profile. Thread dump will be generated here under the bin folder or under profile_home or logs folder of that profile.
When/Why do we need to take thread dumps manually?
1. To analyze the application server response time for a method call.2. To identify the root cause of an application server hang/thread hangs.
3. To scrutinize the under-performing application server and suggest heap corrections or application performance issues with development team.
How to take thread dumps manually ?
There are 2 approaches in this category:1. In Linux/Unix/AIX/HP-UX/Solaris platforms, use "kill -3 <PID>" to generate thread dumps from OS level.
2. You can do this from Websphere supplied wsadmin commands to generate one as well!
Navigate to Application server's profile_home bin directory and execute wsadmin command as shown below:

$AdminControl invoke $JVMNAME dumpThreads
Ex: wsadmin> $AdminControl invoke Server1 dumpThreads
At wsadmin prompt use the above command with JVMNAME = application server name as it appears in logs folder for this profile. Thread dump will be generated here under the bin folder or under profile_home or logs folder of that profile.
How to analyze a thread dump ?
"IBM Thread and Monitor dump analyzer for java" is the tool provided by IBM alphaworks developers portal. Download it and use it. The tool's built-in help notes will detail the options available in just a few steps. It is the most simple tool for thread analysis. There are many other analyzer tools available other than this. It is purely a matter of choice.
After reading this blog post kindly proceed with below link, to better understand automation of thread dumps.

How to generate Heap Dumps manually in Websphere Application Server 7 and analyze?
Although heap dumps are
generated only in response to a detected memory leak, you must understand
that generating heap dumps can have a severe performance impact on WebSphere Application Server for several
minutes. When generating multiple heap dumps manually for memory
leak analysis, make sure that significant objects are leaked in between
the two heap dumps. This approach enables problem determination tools
to identify the source of the memory leak.
On JVM
in WebSphere Application Server, you can manually produce heap dumps
by using the wsadmin tool to run scripts with generateHeapDump operation on MBeans.
On a Java virtual machines
(JVM) in WebSphere Application Server, you cannot enable automated
heap dump generation.
WAS supports the Jacl and Jython scripting languages only, which will be used to interface with WAS through wsadmin.
Steps involved:
1. Start the wsadmin scripting client.
Finding JVM objectName:
<wsadmin> set objectName [$AdminControl queryNames
WebSphere:type=JVM,process=<servername>,node=<nodename>,*]
2. Invoke the generateHeapDump operation on a JVM MBean, for
example,
<wsadmin> $AdminControl invoke $objectName generateHeapDump
where,
| $ | is a Jacl operator for substituting a variable name with its value |
| invoke | is the command |
| generateHeapDump | is the operation you are invoking |
| <servername> | is the name of the server on which you want to generate a heap dump |
| <nodename> | is the node to which <servername> belongs |
After running the wsadmin command above, the file name
of the heap dump is returned.
How to analyze a heap dump generated either wise?
Do not analyze heap dumps on the WAS machine because analysis is very expensive (CPU and disk I/O intensive). For analysis,
transfer heap dumps to a dedicated problem determination machine.
Steps involved:
1. On the physical application server where a memory leak
is detected, go to the WebSphere Application Server
home directory (WAS_ROOT\PROFILE_ROOT\ProfileName).
2. Heap dumps generated here will be in below format:
heapdump.<date>.<timestamp>.<pid>.phd
3. Gather all the .phd files and transfer
them to your problem determination machine for analysis.
Note: In some environments they will be configured to plain text format, you can toggle this on adminconsole websphere variables section.
4. "Memory Dump Diagnostic For Java" is the tool from IBM for heap dump analysis and verbose GC analysis. There are many other third-party tools available to do the same.

Websphere MQ Basics/Fundamentals
IBM WMQ ensures once and only once assured delivery of messages from one business application to another business application.
Pre-defined MQ Objects are 7:
1 Queue Manager
2 Queue
3 Channel
4 Listener
5 Process
6 NameList
7 Service
Queue Manager is initial and foremost object. Unless QM object is defined the other objects cant be created.
The remaining 6 objects can/will be defined in Queue Manager control. Therefore Queue Manager is a sub-system which can control MQ objects.
Queue Manager is SPOC for connecting Business Apps to perform PUT/GET operations on Queue objects.
CRTMQM: is a control command to create a queue manager.
Template: C:\> CRTMQM <QMNAME>
Example: CRTMQM BOCQM1
In production like environment we limit the Queue Manager name to 8 uppercase characters. 8 char is the limit for QM object name.
Name of the MQ server is <QMNAME>
DSPMQ: is a control command to track the current status of QM.
Template: C:\> DSPMQ -M <QMNAME>
Example: DSPMQ -M BOCQM1
Default status of QM is 'ended immediately'.
How to create other MQ objects once QM is defined/created?
QM service should be running.
STRMQM: is a control command to start the QM.
Template: C:\> STRMQM <QMNAME>
Example: STRMQM BOCQM1
DSPMQ: is a contol command which will display QM name and status properties.
Now check the status of QM!
Example: DSPMQ -M BOCQM1
Status of BOCQM1 Queue manager is changed to 'Running'
ENDMQM: is a control command which will be used to stop QM.
Template: ENDMQM -I <QMNAME>, ENDMQM <QMNAME>
Example: ENDMQM -I VANQM1, ENDMQM VANQM1
How to create other MQ objects once QM is defined/created and is running?
RUNMQSC: is a control command To switch/interfacewith QM and define other MQ objects. Once we execute this command, MQSC for QM will be enabled.
All 14 MQSC commands are constant.
Valid MQSC commands are:
1 ALTER
2 CLEAR
3 DEFINE
4 DELETE
5 DISPLAY
6 END
7 PING
8 REFRESH
9 RESET
10 RESOLVE
11 RESUME
12 START
13 STOP
14 SUSPEND
The above MQSC commands will be used for administering the MQ objects defined under QM.
END is an MQSC command which is used to quit the RUNMQSC console(QM control area/WMQ System Admin MQ access).
In IBM WMQ, queues are classified in 2 categories:
1 Pre-defined Q's
2 Dynamic Q's
Pre-defined Q's are 4 in count:
1 Local Q >> Holds business data/messages, therefore its also called business Q.
2 Alias Q
3 Remote Q
4 Model Q >> is a template to create Dynamic Q using model Q object definition and is done in run-time.
Dynamic Q's are 2 in number:
1 Temporary Dynamic Q
2 Permanent Dynamic Q
There are 4 special local Queues(which are not business queues) :
1 Transmission Q
2 Initiation Q
3 Dead Letter Q
4 System Q
GOTCHAS >> If "TYPE(QLOCAL) USAGE(NORMAL)" then such a queue is a business queue. If USAGE(XMITQ) is used instead, then it will become transmission queue.
DEFINE: is a RUNMQSC command used to create pre-defined objects other than QM.
Channel names are limited to 20 characters in length.
Other object names can be upto 48 characters.
Example: DEFINE QLOCAL(QNAME)
DISPLAY: is a RUNMQSC command which is used to display properties of MQ objects other than QM.
Example: DISPLAY QSTATUS(QNAME) TYPE(HANDLE)
ALTER: is a RUNMQSC command used to change the behaviour/property values of objects other than QM.
Example: ALTER QLOCAL(QNAME) PUT(DISABLED) GET(ENABLED)
MAXMSGL: is a Q property which indicates the maximum length of a message that it can hold.
Example: DISPLAY QLOCAL(QNAME) MAXMSGL, ALTER QLOCAL(QNAME) MAXMSGL(40).
By default the maxmsgl property of a q can hold a message of lenth 4 MB each. Remember that it shows maxmessagelength value in bytes.
The maximum message length allowed in MQ is 100MB. Default is 4MB.
gotcha >> TASKKILL /F /PID PROCESSID
Example: TASKKILL /F /PID 3442
DELETE: is a RUNMQSC command used to delete the MQ objects other than QM.
Example: DELETE QLOCAL(TESTQ)

Choosing or Switching Middleware Software
If you think your operating system constitutes the most critical software in your enterprise IT, think again. Middleware looks set to become the IT battleground of the future, the facet of your infrastructure from which you will need to thrash out business advantage. While the operating system is fast becoming a commodity item, the middleware tying applications and processes together is still an ill-defined range of software components, requiring considerable customisation and having no commonly agreed definition. Unfortunately, it is also far harder to get right.
The major analyst firms are predicting a rosy future for middleware. Gartner forecasts that middleware software will account for 28% of IT expenditure by 2015, compared with just 10% in 2002. This latter figure of 1% might seem puzzling given that integration has been a significant overhead in large IT projects for some time, but it only includes the software, not the internal IT effort of making it work. Indeed according to Ed Wrazen, marketing director of middleware consultancy CommerceQuest, integration already accounts for 30% to 40% of the cost of a typical IT project, and often as much as 70%.
Middleware software itself is supposed to ease the integration burden, by providing at least some of the functionality off-the-shelf to link applications together and provide more consistent access to information. In practice though middleware can create as many integration problems as it solves, if care is not taken to adopt a coherent strategy for enterprise application integration (EAI). For just as most large enterprises have a variety of different ERP systems, perhaps because of acquisitions or devolution of IT to local departments, so they have middleware from more than one supplier.
And yet, as Hanafi Houbart, senior consultant in e-commerce at Unipower Systems, points out, changing middleware on any scale is usually difficult and expensive. "In practice no one ever changes established middleware unless either the underlying operating system [bottomware], or overlying applications [topware] are also changed en masse, or the middleware itself has failed to establish well," says Houbart. "That's why middleware products tend to have longer product histories than front-line applications - they just keep getting upgraded."
If there is a time to change your principal middleware supplier though, for whatever reason, it is now. Within a few years middleware will be even more inextricably linked with key platforms and applications, making change yet harder. In theory it should be possible to change horses if the middleware adheres to common standards, but in truth the relevant standards do not yet exist and in any case are hard to crystallise in a continuously changing field. A major problem, according to Kay Hammer, chief executive officer of integration software firm ETI, is that applications are tied in with the middleware via application programming interfaces (APIs) in a way that is hard to standardise and needs completely reworking when you change supplier. This can be a complex process with the danger of introducing errors or unanticipated changes to processes.
"So while over time there will be some standard XML message format that would facilitate moving from one middleware supplier to another, to some extent while you're putting calls into your programs that directly reference their APIs, then you're really putting yourself at some risk," says Hammer.
To avoid becoming effectively locked in to their primary middleware, enterprises must build their own software shell between their applications and the back end or "bottomware" systems such as the database. The most enlightened organisations have already done this, says Hammer, who cites the case of one customer implementing a business-to-business (B2B) infrastructure based on BEA Systems' Web Logic middleware. "They're putting their own shell in because although happy with BEA Systems now, they recognise over time they may need to change their middleware supplier," says Hammer.
The shell handles all the calls into the underlying databases and provides a consistent layer connecting these to the topware applications. The middleware then plugs into this shell, which provides the link to the back-end systems. It is then easier, although still by no means trivial, to change the middleware, because now it just involves re-implementing the shell without changing the calls into backend systems.
Until recently enterprises needing to develop such a middleware shell would have had to do the job themselves, but now tools are emerging to help generate the interface layer. This layer needs to comprise not just hooks, but also information about what is being connected to, and what is being done. In effect, therefore, it should comprise metadata, providing a map to the back-end databases as well as information about how the front-end applications are accessing this. The big weakness of existing middleware suppliers is their lack of a metadata strategy, according to Hammer.
This applies even to the mature core application messaging products such as IBM's MQ Series and Microsoft's Message Queue. The latter is used mainly within the Microsoft environment, while MQ Series dominates the enterprise messaging environment with 70% of the market for software communication across platforms, as opposed to within a single operating system environment. MQ Series is almost synonymous with middleware in some minds, but while it has a good reputation it does not by itself provide the data and process management necessary to keep track of changes and ease the integration burden as new applications are developed.
MQ Series allows messages to be routed within an application framework to the correct system and then cause a process there to execute, triggering as it is called. What it does not do is provide a record of the routes and triggers, which would make it easier to manage the environment and effect changes.
There are some tools now that help with this, one being ETI's Extract Accelerator for MQ Series, which is a development aid for generating the calls and providing an audit trail of all the links to back-end systems and databases. Although currently only available for MQ Series, such a product would ease the pain of switching to another middleware supplier, because of the information it provides on all the inter-process links.
Middleware though is increasing its scope beyond application messaging. Products like MQ Series are asynchronous, providing a loose coupling between processes, so that one might send a message to another but not expect any response. There is also a need for protocols that support direct interaction, integrating applications more tightly together, and there are various products that allow this, including some of the tools within the object oriented Common Object Request Broker Architecture.
Because of the expanding scope of middleware, IBM has just gone through a re-branding exercise, bringing all the products together under the WebSphere logo. Not for the first time in IBM's case, the re-branding exercise is more a statement of intent than a fait accompli - ie, being a collection of often admirable but not particularly compatible products. According to Geoff Rayner, financial director in charge of IT at eHospital, an IBM middleware site which specialises in B2B trading in healthcare, WebSphere is not yet the answer to an enterprise's middleware integration problems that IBM would like its customers to believe. "WebSphere is an amalgamation of 1,000 things at present. People are confused by what's in there, and we've been through that learning curve ourselves just to find out what's in it."
Yet IBM's competitors can take little heart from these comments, for Rayner reckoned that they are all less well prepared for the challenges to come. "There's a big effort internally in IBM to bring it all together. The good thing for us is we don't have to pay for all that work."
In the hospital field, which Rayner describes as an IT nightmare with its huge collection of incompatible systems from a wide variety of suppliers, IBM's MQ Series is the best technology available for providing at least a basic level of integration between systems. This is providing real benefits for doctors and other workers within healthcare, Rayner insists. For example MQ is shortly to be used to integrate materials management with procurement and the supply chain within some hospitals, which will enable consultants, nurses and others to re-order surgical consumables by scanning as they leave or enter a ward rather than having to sit down in front of a terminal, or worse fill in a form. The key to MQ Series' success, says Rayner, is the number of different APIs it would communicate with, making it the best technology to form the core of a middleware strategy for a multi-supplier environment.
Not surprisingly, other suppliers dispute this relatively rosy view of IBM's position, arguing that it ignores the expanding role of middleware, beyond mere application integration, into unified content and document management. According to Tom Bird, UK head of collaborative working software supplier iManage, the missing piece of many middleware solutions is the support for common access to documents. "Over 80% of a corporation's knowledge exists in its documents," notes Bird, who adds that middleware did nothing on its own to open up documents and make them available to collaborative working communities, both within organisations and in B2B applications. The need is to elevate middleware into the spheres of content, document and knowledge management, Bird asserts.
In fact this point has not been lost on traditional middleware suppliers, and is one motive behind some of the recent rebranding exercises. Indeed BEA Systems, which is the main challenger to IBM in the middleware arena, is moving higher up the software food chain, according to its senior architect for UK and northern Europe, Mark Prichard. Particular targets for BEA, he says, are the content management suppliers such as Broadvision and Vignette. "Our differentiator compared with Broadvision is that we can provide almost as much functionality, but based entirely on the Enterprise Java Beans standards, with no proprietary kernel." This, says Prichard, made it easier to integrate content management with other key applications such as personalisation. "Enterprises prefer to go with a single supplier, but also want an open standards-based solution, even if the out-of-the-box functionality in a particular vertical market such as content management is not quite as deep."
With this comment, Prichard identifies the old dilemma for enterprises, which is whether to go with a perfect set of point solutions to individual problems, or compromise with a single supplier framework that will have weaknesses in some areas but eases the integration burden. In the case of middleware there is no sign of this dilemma being resolved.
Key middleware players
BEA is unique among the big five in being independent, or at least perceived to be, from any particular hardware or software platform. Yet it is IBM with MQ Series that is strongest in the market for middleware linking Unix and non-Unix systems, via its MQ Series messaging software.
NOTE: BEA Systems + Sun Microsystems are now merged with Oracle, making Oracle Weblogic and Fusion middleware as strong contenders for IBM's Websphere range of products. JBOSS needs a lot of corrections in its enterprise version (v6) before companies can transform. However IBM provides the worlds best after sales services including customer care. Oracle stands just next to it. JBOSS in not in this race. (Not inclined to any vendor - it is just my perspective)
Tips for changing middleware
- Understand why you are changing middleware, and work out what is wanted, for example greater ability to integrate with other systems you have
- Consider the change in the light of overall IT strategy. For example you may be implementing mobile applications in which case the new middleware must be capable of supporting pervasive computing and Wap devices
Assess the features required. Typical features include asynchronous message queuing, message broking which facilitates synchronous and more closely integrated processes, support for distributed transactions, security, access to legacy systems, and support for small mobile devices
Look at the products. Many suppliers call their products middleware, but with wide differences in functionality, capability and all round coverage. A key point to consider is what level of integration is needed
Run a pilot project, especially if a major change of middleware right across an enterprise is being considered
Start by migrating just one application. If the new middleware cannot cope, perhaps lacking sufficient support for key emerging standards such as Compact XML for small devices, then it is less costly to withdraw at this stage.
Review the initial migration thoroughly before committing the whole enterprise. Determine the roadmap for future platform evolution, skills required, and define the enterprise's own middleware architecture accordingly - do not rely entirely on the supplier for this
If all appears well, plan the full roll-out
Execute the plan

What is the difference between heap dump, thread dump and a core dump?
Heap dump - Collection of objects that are in memory (JVM)
Thread dump - Shows what each thread in a process is doing at a given point in time along with the stack trace.
Core dump - O/S level dump file which has O/S level info in addition to the heap dump.
Heap dump - is useful to analyse OOM situations.
Thread dump - To troubleshoot slow running of your application.
Core dump - When your JVM has crashed abruptly. To find details about native calls and so on.
Core dump will be generated automatically if a program crashed due to segmentation fault or some other reason. But core dump will not be generated if an application halt and been terminate by control+c or conventional way of kill or pkill.
In order to force a core dump generation you could run kill -6 <PID>
You should also make sure that you have enabled it and have provided enough space and permissions for it to get generated.
For Linux, the coredump is turned off by default on all systems. For RedHat Advanced Server 2.1, it should be under /etc/security. There should be a self-explanatory file called limits.conf and look for the word "core". If set to "0", then coredump is disabled.
For Solaris, you can also make sure core files are enabled with the coreadm command.
Check ulimit -a to see whether your environment allows core files to be produced.
ulimit -c (This is the size limit of the core file. Fix it with ulimit -c unlimited).
Kernel limitation (hard limit for ulimit -c).
Available disk space for the user (e.g., is there disk quota?).
Thread dump - Shows what each thread in a process is doing at a given point in time along with the stack trace.
Core dump - O/S level dump file which has O/S level info in addition to the heap dump.
Heap dump - is useful to analyse OOM situations.
Thread dump - To troubleshoot slow running of your application.
Core dump - When your JVM has crashed abruptly. To find details about native calls and so on.
Core dump will be generated automatically if a program crashed due to segmentation fault or some other reason. But core dump will not be generated if an application halt and been terminate by control+c or conventional way of kill or pkill.

Architecture
WAS is built using Open standards such as Java EE, XML, and Web Services. It is supported on the following platforms: Windows, AIX, Linux, Solaris, i/OS and z/OS. Beginning with Version 6.1 and now into Version 8.5, the open standard specifications are aligned and common across all the platforms. Platform exploitation, to the extent it takes place, is done below the open standard specification line.It works with a number of Web servers including Apache HTTP Server, Netscape Enterprise Server, Microsoft Internet Information Services (IIS), IBM HTTP Server for i5/OS, IBM HTTP Server for z/OS, and IBM HTTP Server for AIX/Linux/Microsoft Windows/Solaris. It uses port 9060 for connection as the default administration port and port 9080 as the default website publication port. In case you install more WebSphere instances these values will be changed.

IBM has shipped several versions and editions of WebSphere Application Server.
In the first beta versions, WebSphere had been called Servlet Express.
Although the versioning scheme x.1 and x.5 would usually indicate a minor release in the software industry, WebSphere v6.1 and v5.1 are major releases, just like WebSphere v8.5 and v3.5.[8]
Version 8.5.5
WebSphere Application Server V8.5.5 includes significant enhancements to the Liberty profile compared to v8.5. The WebSphere Application Server Liberty Core edition leverages the lightweight and dynamic aspects of the Liberty profile.Version 8.5
WebSphere Application Server V8.5 offers the same Java EE 6 and Java SE 6 (by default) as V8.0 and also provides - and can be configured to run on - Java SE 7. The primary new capabilities in V8.5 are the Liberty profile of WebSphere Application Server and the intelligent management features.The Liberty profile of WebSphere Application Server is included with all the commercial editions of the server, providing a lightweight profile of the server for web, mobile and OSGi applications. It is a functional subset of the full profile of WebSphere Application Server, for both development and production use, with an install size of under 50 MB, a startup time of around 3 seconds and a new XML-based server configuration which can be treated as a development artefact to aid developer productivity. Server capabilities are engaged through the set of features defined in the server configuration; features are added and removed dynamically through internal use of OSGi services. A new model is provided for moving applications through the pipeline from development to production as a packaged server; this is a complete archive of the server, server configuration and application for unzip deploy. A centralized managed install is optionally available through the Job Manager component of WebSphere Application Server Network Deployment edition.
Intelligent management capability is added in the Network Deployment and z/OS editions of WebSphere Application server. This integrates operational features that were previously available in the separate WebSphere Virtual Enterprise (WVE) offering: application editioning, server health management, dynamic clustering and intelligent routing.
Version 8.0
This version was released on June 17, 2011. It is a Java EE 6 compliant application server and incorporates the capabilities originally delivered as feature packs with WebSphere Application Server V7. This version of WebSphere Application Server is installed using the IBM Installation Manager.Version 7.0
This version was released on September 9, 2008. It is a Java EE 5 compliant application server.Following are the flagship features introduced by WebSphere Application Server Version 7:
- Flexible Management
- Business-Level Application
- Property Based Configuration
Between the general availability of WebSphere Application Server V7 and WebSphere Application Server V8 (in 2011), a number of additional capabilities were made available for V7 in the form of feature packs which are optionally added to a V7 install. Feature Pack content has the same quality and support as main release content - the purpose of a feature pack is to deliver new innovation before the next major release. The following feature packs were provided for WebSphere Application Server V7:
- Feature Pack for Modern Batch
- Feature Pack for OSGi Applications and JPA 2.0
- Feature Pack for SCA
- Feature Pack for Web 2.0 and Mobile
- Feature Pack for XML
- Feature Pack for Communication Enabled Applications
Version 6.1
This version was released on June 30, 2006. On September 11, 2012, IBM extended the end of service for V6.1 by a full year, to September 30, 2013, and announced new version-to-version migration incentives and assistance.[9] It is a Java EE 1.5 compliant application server and includes the following function:- Support for Java Standard Edition 1.5
- Support for running JSR 168 Portlets in the application server
- Session Initiation Protocol (SIP) Servlets
- Enhancements to the WebSphere Install Factory
- IBM Support Assistant
- IBM JSF Widget Library
- Simplified Administration
- Improved Certificate and Key Management
- Security Enhancements
- Administration of IBM HTTP Server from WebSphere Admin Console
- Support for (pre-OASIS) WS-Security 1.0
- Support for Web Services Resource Framework and WS-BusinessActivity (WS-BA)
- Support for JSR160 JMX Remote Connections (From IBM Agents Only)
- Administrative Console Jython Command Assistance
- Enhanced scripting. This version started the deprecation process for the Jacl syntax.[10]
- 64-bit servants and a new Apache-based IBM HTTP Server for z/OS
- Asynchronous programming model (Limited functional support)
- Multiple Payload structures
- StAX (Streaming API for XML)
- WS-RM (Limited functional support)
- Support for (OASIS specified) WS-Security 1.0.
- WS-Addressing (Limited functional support)
- JAX-B support
- Policy Set (Limited functional support)
- Secured thin client (Limited functional support)
- SOAP (protocol) Message Transmission Optimization Mechanism (MTOM)
- Supports CGI and CORBA
Version 6.0
- This version was released on December 31, 2004. It is a Java EE 1.5 compliant application server. Security enhancements include support for JACC 1.0 and (pre-OASIS) WS-Security 1.0.
- Support for Java Standard Edition 1.4
- Community Edition (free, support for fee)
- Code based on Apache Geronimo project
- Many programming model extensions previously found in WebSphere Application Server V5.0 Enterprise Edition were moved out of enterprise and into Express and Base. These APIs included application profile, startup beans, the scheduler, and async beans.
- The JMS engine, now called "WebSphere Platform Messaging," was rewritten in 100% Java and its functionality greatly enhanced. (WebSphere MQ is still supported as the JMS provider and is interoperable with WebSphere Platform Messaging.)
- The clustering was rewritten to use the high availability manager. This manages all singletons in the WebSphere environment and can provide hot recovery for those singletons.
- WebSphere was modified so that a shared file system can be used to store transaction logs and this meant that any cluster member with that shared file system mounted can hot recover in-doubt XA transactions with no external HA software.
- The Deployment Manager's role was eliminated from all clustering runtime operations. It's only required for centralized JMX admin and config changes.
- Now supports running mixed version cells (V5 to V6) in production.
- WebSphere Application Server for z/OS
- Provides the same core functionality as Network Deployment, since it shares a common programming model, but still contains the platform advantages such as:
- z/OS Workload Manager for prioritized management of mixed workloads
- Resource Recovery Services (added transactional integrity for complex, critical transactions)
- Support for security mainframe products such a RACF
- Advanced vertical scaling for application server by featuring a unique control region (integrated control area) server region (where workloads are completed) separation which enables the control region to open and close server regions as needed by the volume of incoming requests
- Parallel Sysplex support for full participation in the Sysplex, enabling advanced failover support and a geographically dispersed environment that seamlessly acts as one with a centralized logging and management facility
- WAS XD as it is known increases the functionality of the application server in two main areas - Manageability and Performance. It also allows makes possible new configurations, such as dynamic virtualization between pools of application servers.
- Under the performance header the ObjectGrid component was added, which is a standalone distributed cache that can be used with any application server (any version with a 1.4 JDK) or with any J2SE 1.4 runtime, including zLinux and z/OS support.
Version 5.1
This version was released on 16 Jan 2004. It is a J2EE 1.4 compliant application server.- Express
- Base
- Network Deployment
- WebSphere Application Server for z/OS
- Version 5.1 for z/OS is the first to support zAAP engines.
- WebSphere Business Integration Server Foundation V5.1
- This is the follow on product to WebSphere Application Server Enterprise Edition V5.0. The workflow engine was updated to support BPEL rather than the proprietary FDML format used in V5.0. The product was also repriced and available on all IBM platforms from the Intel environments to the mainframe.
- WebSphere eXtended Deployment (XD)
Version 5.0
The version released on 19 November 2002. This was a J2EE 1.3 certified application server. It was a major rewrite of the V3/V4 codebase and was the first time WebSphere Application Server was coded from a common codebase. Now WAS across all deployment platforms, from Intel x86 to the mainframe, are substantially the same code. The database-based configuration repository was replaced with a replication XML file-based configuration repository. A service called the Deployment Manager had the master copy of the cell configuration, and nodes had the file(s) they needed copied from this master server whenever they changed. V5 also included a miniature version of MQ 5.3 called the embedded Java Message Service (JMS) server.- Express Edition replaces the Standard Edition. Express now becomes the term to indicate SME-oriented offerings from IBM, across all its software brands.
- Base
- Network Deployment. This version supports deployment of a cell configuration with cluster and J2EE failover support. It now also includes Edge Components, previously known as Edge Server. This provides a proxy server, load balancing, and content-based routing.
- Enterprise Edition. This version added a workflow engine, called the Process Choreographer, for the first time but predates the BPEL standard. It also added the first fully supported application threading model called WebSphere Asynchronous Beans.
- WebSphere Application Server for z/OS. This version is essentially the same as the Network Deployment product but is optimized to take full advantage of z/OS features, such as Workload Manager, to leverage the key technologies that make the mainframe indispensable for mission-critical, scalable, and secure workloads.
Version 4.0
This was a J2EE 1.2 certified application server. It inherited the database-based configuration model from V3.x for all but the single-server edition, which already used an XML datastore.- AE (Advanced Edition)
- AEs (Advanced Edition single). Single-server edition that was not able to run in a cluster configuration.
- AEd (Developer Edition). Functionally equivalent to AEs, but intended only for non-production development use.
- EE (Enterprise Edition)
Version 3.5 (and 3.0)
WebSphere 3.5 is the first widely used version of WebSphere.Version 2.0
IBM adds JavaBean, CORBA and Linux support. Comes in two editions: Standard Edition (SE) and Advanced Edition (AE).Version 1.0
Initial release in June, 1998. Was primarily a Java Servlet engine.Security
The WebSphere Application Server security model is based on the services provided in the operating system and the Java EE security model. WebSphere Application Server provides implementations of user authentication and authorization mechanisms providing support for various user registries:- Local operating system user registry
- LDAP user registry
- Federated user registry (as of version 6.1)
