It is IBM software products are special for their uniqueness. WebSphere is JEE Application Server.
IBM WebSphere runs on its own JDK. So IBM JVM has its own segragation to the JVM Heap classification. For OOM errors you need to work with Heapdumps, but it can be created with different way than Sun HotSpopt JVM.
Application Servers comparison: an administrative perspective
IBM WebSphere applications deployment is different compare to WebLogic, the JEE components in an archived form can be backup from the console in the WebSphere. You need to connect to console, go to the applications WebSphere applications what you wish to backup. select it and select the button "Export". This can be useful when the code deployment fails then we need to rollback the deployment. Such situation you requre the old code.
What makes WebSphere different from other Application Servers
While the application servers are in running state you can specify the logging parameters and it can take effect immediately.When this debugging log overloaded server automatically goes to info level logging for the application server.
Being in the WebLogic Application serverver side it makes more favorite console, compare to IBM WebSphere console. WebLogic more advanced options will be visible at the bottom of the right pane, where as WebSphere you can see in the right most part of the right pane.
In WebSphere environment configurations can be view, edit, changes to the configuration for this we may use wsadmin. To change wsadmin.sh or wsadmin.bat to use Jython by default language, you can edit the wsadmin.propertiesfile located in <was_install_root>/properties directory
If you are in UNIX environment vi wsadmin.properties file and search with '/defaultLang'. The actual line will be like this:
Now change it to
I wonder that 'How IBM WebSphere set this JACL as default, when JACL has been declared as deprecated scripting language for WebSphere.
How do you verify the request hitting the one of the cluster member?
To checking this you need to use little trick, hostname of the application server with port and followed by the application context path it must give the accessing info.
