For IFS objects, default configuration values result in system journal replication. Data group IFS entries can be optionally configured to allow user journal replication of specified IFS objects with cooperative processing. Or, the data group can be optionally configured as journal-centric for IFS to replicate all IFS objects journaled to the associated user journal.
For data area and data queue objects, default configuration values result in user journal cooperative processing. Or, the data group can be optionally configured as journal-centric for *DTAARA or *DTAQ to replicate all data areas or data queues journaled to the associated user journal.
In addition to configuration and journaling requirements and the restrictions that apply, you need to address several other considerations when planning to replicate journaled IFS objects, data areas, or data queues. These considerations affect whether journals should be shared, whether objects should be replicated in a data group shared with database files, whether configuration changes are needed to change apply sessions for database files, and whether exit programs need to be updated.
