Db2 Mirror for i - 5770-DBM
Note: The following functions require Db2 for i PTF Group SF99704 Level 13 and Db2 Mirror for i Group SF99668 Level 10

Security

The Analyze Profile Activity (ANZPRFACT) command has been updated to consider Db2 Mirror environments. Prior to this enhancement, ANZPRFACT would consider activity only on the node where the command executed. This could cause active profiles on the other node to become disabled. This enhancement will now be multi-node aware and disable profiles only if there is no activity on either Db2 Mirror node.

Db2 for i performance improvements

Db2 for i has been enhanced to increase performance in a Db2 Mirror environment. Performance improvements vary based on application and database architectures. See the Db2 Mirror Performance FAQs for more specific details about Db2 Mirror performanceSee IBM Db2 Mirror for i: Perfomance Considerations for additional information.

New objects supported

Data Queue entries are now supported in addition to the data queue itself. This is selected by the data queue and managed by the Replication Criteria List.

User Index and User Space objects can now also be replicated with Db2 Mirror. For more information on these new objects that can be replicated, see the Db2 Mirror topic.
