Message Type:
Warning
Description:
The PLO (z/OS Perform Locked Operation) command failed.
PLO is used to serialize the manipulation of three queues/lists used to communicate between the exits and the agent. The Recorded Image queue contains recorded images to for the agent to process. The Playback Image queue contains playback requests for the agent to process. The LPAR Agent List contains the playback responses that the agent receives to be passed to the exits.
For a Recorded Image queue entry, the exit discards the recorded image.
For a Playback Image queue entry, the image is discarded and the transaction continues without playback (virtualization).
For an LPAR Agent List entry (playback response), the image is orphaned on the LPAR Agent List by the exit.
Action:
Report the error to Support.
