9.1. Using the DISPLAY TRACE command

To display the current trace option in effect issue the MVS DISPLAY TRACE command. Figure 9-1 shows an example of the output generated by the DISPLAY TRACE command.

Figure 9-1 shows that we have system trace (ST) enabled, with 256K allocated for the system trace table on each processor and 512K allocated to the system trace table buffers. Address space (AS) tracing is ON and branch tracing is OFF, as is explicit software tracing. Master tracing is ON with a master trace table size of 24K. This also displays the status of component and sub-component traces.
