DFS3433W ACBLIB MEMBER OLC ID MISMATCH MOLCID=yyyyddd hhmmss

Explanation

One or more ACB library member online changes occurred while IMS was not active in the IMSplex. IMS restart processing detected that the value in the MOLCID field in the restart checkpoint log record (X'4001') is not the same value as in the MOLCID field in the OLCSTAT data set. MOLCID=yyyyddd hhmmss is the local time stamp of the last member online change process that was committed while IMS was not active in the IMSplex.

System action

IMS restart continues normally.

System programmer response

If ACBSHR=Y, then the ACB library member online change has been included and the restarting IMS does not need to take any action.

If ACBSHR=N, then its ACB library does not include any ACB member online changes while the restarting IMS is down.

When this message is issued because ACBSHR=N is specified for this IMSplex, it means that:
  • IMS systems in the OLCSTAT data set do not share ACB libraries.
  • One or more ACB library member online change processes occurred while this IMS was not active in the IMSplex.
  • The ACB member online changes that occurred while this IMS was not active in the IMSplex are not in the active ACB library of this IMS.

Manually update the ACB members in the ACB library so that the 1MOLCID field in the X'4001' log record matches the MOLCID field in the OLCSTAT data set.

Attention: If you run this IMS before the MOLCID values match, IMS might have data integrity problems or might terminate abnormally.

To make the MOLCID values match, perform one of the following tasks:

  1. Perform one or more ACB member online change processes to synchronize the MOLCID field in the X'4001' log record with the MOLCID field in the OLCSTAT data set.
  2. Shut down IMS and run the ACB Maintenance utility.
    1. Shut IMS down normally.
    2. Run the ACB Maintenance utility for those member online changes and apply the changed ACBs directly to the active ACB library. Ensure that the ACB library includes all the ACB library members online up to the time of the MOLCID in DFS3433W.
    3. Restart IMS.
