Logging Db2 Data in a Data Sharing Environment

Logging Db2 Data in a Data Sharing Environment

The Post-Log Merge option of the PowerExchange Logger allows you to capture changes using multiple PowerExchange Loggers on multiple z/OS systems and then extract the merged changes from a single Logger. With Db2 data sharing, the Post-Log Merge option of the PowerExchange Logger for z/OS is not required.
The Db2 ECCR uses Db2 IFI 306 calls that return change information from all members in the data sharing group.
Post-Log Merge is not required for Db2 data sharing. However, if Post-Log Merge is used for another reason, the Db2 ECCR can also attach to a member Logger of the Post-Log Merge group, even when running in data sharing mode. A single Db2 ECCR is all that is required, even when connecting to a PowerExchange Logger in a Post-Log Merge configuration.
