Before tracing and debugging your OS/390 server application, you must configure the WebSphere Application Server environment to enable tracing and debugging. This section describes how you can prepare the OS/390 host environment when you have the Advanced Single Server Edition of the WebSphere Application Server installed.
Before preparing your OS/390 WebSphere Application Server environment, ensure you have the following products installed on your OS/390 system:
Also, ensure that both WebSphere Application Server and the HTTP server are down while doing the following configuration.
To configure your OS/390 WebSphere Application Server environment to trace and debug your server applications:
Refer to the WebSphere Application Server for OS/390: WebSphere Application Server Advanced Single Server Edition Planning, Installing, and Using Version 3.5 or later manual for a description of how to enable the debug JVM.
Refer to the WebSphere Application Server Advanced Single Server Edition Planning, Installing, and Using Version 3.5 or later manual for a description of how to enable Object Level Trace.
objectleveltrace.enabled=true objectleveltrace.host=<HOSTNAME> objectleveltrace.port=2102
where <HOSTNAME> is the workstation hostname where OLT server is running.
appserver.product.java.jvmdebug.debug=true appserver.product.java.jvmdebug.port= 7777
The second entry sets the port number that the VM would use to connect to the debugger. This is a random number.
