Allocation problems

Symptoms

WebSphere MQ issues the following message:

CSQJ103E +CSQ1 LOG ALLOCATION ERROR DSNAME=dsname,
           ERROR STATUS=eeeeiiii, SMS REASON CODE=sss

z/OS dynamic allocation provides the ERROR STATUS. If the allocation was for off-load processing, the following message is also displayed:

CSQJ115E +CSQ1 OFFLOAD FAILED, COULD NOT ALLOCATE AN ARCHIVE
           DATA SET

System action

The following actions take place:

• If the input is needed for recovery, recovery is not successful, and the queue manager ends abnormally.

• If the active log had become full and an off-load was scheduled but not completed, off-load tries again the next time it is triggered. The active log does not reuse a data set that has not yet been archived.

System programmer action

None.

Operator action

Check the allocation error code for the cause of the problem, and correct it. Ensure that drives are available, and either restart or wait for the off-load to be retried. Be careful if a DFP/DFSMS ACS user-exit filter has been written for an archive log data set, because this can cause a device allocation error when the queue manager tries to read the archive log data set.
