IPCS CTRACE subname query

If the trace data set is an SVC dump, the trace subname must also be specified. This subname is the aggregation of the address space's jobname with its ASID (address space identifier), in printable hexadecimal.

An easy way to determine the subname is to query CTRACE for the data using the following IPCS subcommand:

CTRACE QUERY DSN('dump.data.set')

Once you get the subname you can view the WebSphere® Application Server for z/OS® trace data with the following IPCS subcommand:

CTRACE COMP(CELL_SHORT_NAME) SUB((subname)) FULL DSN('dump.data.set')

where CELL_SHORT_NAME is the value specified through the Profile Management Tool or the zpmt command to identify the location of server configuration files. The name must be 8 or fewer characters and all uppercase.

Note: The subname parameter is optional for only the trace data set. It is required when viewing the trace data using the dump data set.
