DSNB818I ASYNCHRONOUS CROSS-INVALIDATION WRITES WITH ASYNCH XI = asynch-xi-write-count SYNCH-UP CALLS = synch-up-calls-count SUSPENSIONS FOR SYNCH-UP = suspension-count

Explanation

This message is a section of output from the DISPLAY GROUPBUFFERPOOL command, which is part of message DSNB750I.

DSNB818I: Asynchronous cross-invalidation writes

If the DISPLAY GROUPBUFFERPOOL command included the MDETAIL option, the output includes asynchronous cross-invalidation statistics for the group buffer pool. The term asynchronous means that the cross-invalidation operations occur asynchronously with the completion of coupling facility write requests.

                      SUSPENSIONS FOR SYNCH-UP       = suspension-count

asynch-xi-write-count

The number of coupling facility write requests for which cross-invalidation operations occurred asynchronously with the completion of write requests.

synch-up-call-count

The number of calls to the coupling facility asynchronous cross-invalidation service that were made to determine when asynchronous cross-invalidation operations completed.

suspension-count

The number of suspensions of the coupling facility asynchronous cross-invalidation service that occurred during waits for asynchronous cross-invalidation operations to complete.
