Verify tracing for component traces with sublevels

The commands for verification depend on the component trace.

To verify a SYSJES component trace, the operator enters the following command to verify a SYSJES trace; the system will show the 4 sublevel traces.

display trace,comp=sysjes,sublevel,n=4

When a SYSXES component trace has multiple sublevel traces, a DISPLAY command shows only one sublevel. To verify a SYSXES component trace, the operator needs to enter multiple DISPLAY commands to see the multiple sublevels.

A SYSXES component trace has structures, address spaces, and connections. The following examples show the DISPLAY (D) command entered by the operator and the type of information that the system returns.

To see how the SYSXES component trace is set up.
