Once activated, the WebSphere Application Server for z/OS always writes trace data into memory buffers. The number and size of these buffers is controlled using WebSphere variables. You can get this trace data from a dump, which may be taken by the system or requested by the operator through DUMP or SLIP commands.
To view messages or application trace data from Component Trace, you must use the interactive problem control system (IPCS) to format the data. The source of the trace data can be a dump data set or a trace data set, and the command to use would be
IPCS CTRACE. You can also use the
IPCS CTRACEcommand to merge multiple trace entities together such as multiple WebSphere Application Server for z/OS address space traces, OMVS, and TCPIP.
