Displaying Information

Through variations of the DISPLAY command, operators or system programmers can determine the status of APPC/MVS resources related to protected conversations:

The DISPLAY APPC,LU command output contains the resource manager name for LUs that are registered with RRS, and indicates whether each LU is syncpoint capable
The DISPLAY APPC,TP command output contains the following for each of the TP's conversations:
- The logical work unit identifier (LUWID)
- An indication of whether the conversation is protected or unprotected
- An indication of whether a syncpoint operation is in progress.
The DISPLAY APPC,UR command output contains information about each unit of recovery associated with a protected conversation.

DISPLAY APPC,SERVER command output does not contain information about served TPs' protected conversations. To obtain such information, use the DISPLAY APPC,TP command.

For a summary of DISPLAY APPC commands and various sample commands and output, see Tracking Changes to the APPC/MVS Configuration and Workload. For DISPLAY APPC command syntax and parameter descriptions, see z/OS MVS System Commands. An installation can also use RRS ISPF panels to display APPC unit of work activity. For more information, see z/OS MVS Programming: Resource Recovery.
