Error description
As backout was occurring for a long-running unit of work, the following errors occured: CSQJ103E CSQJDS06 LOG ALLOCATION ERROR, ERROR STATUS=02200000, SMS REASON CODE=00000000 CSQJ151I CSQJR003 ERROR READING RBA rba, CONNECTION-ID=id CORRELATION-ID= REASON CODE=00D1032B CSQV086E QUEUE MANAGER ABNORMAL TERMINATION REASON=00D94001 IEA794I SVC DUMP HAS CAPTURED: DUMPID=061 REQUESTED BY JOB (ssidMSTR) DUMP TITLE=ssid,ABN=5C6-00D1032B,U=SYSOPR ,M=CSQJRE01,LOC=CSQJL002.CSQJR003 IEF450I ssidMSTR ssidMSTR - ABEND=S6C6 U0000 REASON=00D94001 Reason 0220 for DYNALLOC: Meaning: Requested volume not available.(dsname allocation) This reason code may mean that the data set is in use by someone else and that it has an ENQ. The archive log in question had been created several minutes earlier so should have been available. If the timing of the dump does not show the ENQ, VERBX GRSTRACE 'DETAIL QNAME(SYSDSN)' may show the history of it. The ENQ was held longer than expected by MQ due to non-zero values for the DEALLCT and MAXRTU parameters in CSQ6SYSP. This is the same problem described in DB2 APAR PK85641.

Local fix
Set the CSQ6LOGP DEALLCT parameter to zero in zparm.

If any tape volumes are in delayed deallocation, MQ will 'steal' the tape unit by modifying the JFCB with the new archive log data set information and issuing an OPEN-J for this archive log. The original archive volume will be closed and unloaded, allowing the new archive log volume to be opened on the allocated tape unit. Even though the tape volume has been unloaded, the ENQ on SYSZVOLS for the archive log tape volume is not released.
Problem conclusion
MQ will now mark an archive log data set in delayed deallocation as 'expired', so it will be deallocated when MQ has reached the maximum archive tape unit count. This will allow the new archive log tape read request to be honored after the 'expired' archive log tape unit has been deallocated. 000Y CSQJR206 CSQJR208
