Db2 Mirror Object Replication Capability Extended to User Indexes, User Spaces, and Data Queues

IBM® Db2® Mirror for i PTF Group SF99668 Level 10 enables Db2 Mirror object replication capability for User Indexes (*USRIDX) and User Spaces (*USRSPC).

IBM Db2 Mirror for i PTF Group SF99668 Level 11 extends the Db2 Mirror object replication capability for Data Queues (*DTAQ).

If Db2 Mirror is being used with a Default Inclusion State of *INCLUDE, or if Replication Criteria List (RCL) rules are in place to INCLUDE all replication eligible objects within a library, the application of SF99668 Level 10 or Level 11 will automatically extend the coverage of replication to include these object types.

After PTF SI74263 (included in SF99668 Level 10) or PTF SI76222 (included in SF99668 Level 11) has been applied to both Db2 Mirror nodes, the RCL will be used by Db2 Mirror to reevaluate the object replication eligibility. This reevaluation of the RCL rules will determine if any non-replicated objects should be added to Db2 Mirror replication. Any objects added to replication are then added to the Object Tracking List (OTL) on the primary and/or secondary nodes to establish replication for those objects.

If an object being added to replication is found on both nodes and the object is not already in sync, the object will be added separately to the OTL on both nodes.

Db2 Mirror resynchronization includes a comparison of the OTLs on the primary and secondary nodes. If the comparison identifies objects which conflict, resynchronization will fail. The admin will then need to determine which version of the object should be used for replication by Db2 Mirror. For additional information on managing the OTL or the resynchronization processing refer to the section in the Db2 Mirror publication at: https://www.ibm.com/docs/en/i/7.4?topic=environment-managing-object-tracking-list
