DSNB813I   csect-name ALTER NOTIFICATION FAILED

Explanation

An ALTER GROUPBUFFERPOOL command failed to propagate the request for castout threshold or checkpoint interval change to other DB2s in the data sharing group. This error is triggered by an error encountered by the IRLM notification process. As a result, different DB2s in the group might have different values for the castout threshold or checkpoint interval. The RATIO change does not use the notification process and is, therefore, not affected by such a failure.

System action

Processing continues.

System programmer response

Reissue the -ALTER GROUPBUFFERPOOL command with the same parameters. If the problem persists, it indicates a deeper problem, such as inadequate space for the locking structures.
