Tracing Specific Connections

If you want to trace the communication to a specific processor or CPC, issue one of the following service commands:

INGHWCMD proname TRACE ON
INGHWCMD proname UTRACE ON

Where proname is the name of the target hardware or processor that is defined in the SA z/OS customization dialog, and specifying UTRACE traces only the user session of the operator that issued the command.

Use the following service commands to disable the trace:

INGHWCMD proname TRACE OFF
INGHWCMD proname UTRACE OFF

Although only a single processor connection is traced, the amount of data that is written to the netlog may be high, especially if the processor connection is through an HMC. In this case, data from other processors that are serviced by this HMC is additionally shown in the trace. It is therefore recommended to limit the tracing time.
