Want to reduce the number of members in your DB2 for z/OS V10 data sharing group?
For customers who are looking to reduce the number of members in their DB2 for z/OS V10 data sharing group, the APAR that provides this support – PM51945 – closed on November 1st 2011. It provides updated support to the Change Log Inventory (DSNJU003) stand-alone utility to allow you to deactivate a member within a group and then optionally delete it permanently.
The deactivate can be reversed, but be warned that once you have delete/destroyed a member from the group it is gone and the member ID is available for reuse.
Note that the group must be brought down to perform these operations and that a member must be deactivated before it is destroyed – so two group outages are required to implement a member removal.
The updated documentation is available on the IBM Information Centre for DB2 V10 here:
