We have previously discussed how you can automatically start journaling newly created files by creating the data area named QDFTJRN. In V5R4, IBM enhanced the capabilities of the QDFTJRN data area to allow it to automatically start journaling data queues and data areas. V5R4 also introduced the capability to start journaling files not only on create operations but also on restore operations. This means that when you restore an object it can automatically start journaling.

In response to a large number of customer requests, IBM has now added (via four PTFs) the ability to have the restored objects start journaling to a different journal than the one used at the object save time. So, if you have objects journaling to a test journal and save and restore them on a production system, you can override the journal used for the objects to the production journal, rather than the test journal from the other system.

The new PTfs for the Restore Override Journal capability are: SI24505, SI24794, SI24812 and SI24864.

Go to the V5R4 Info Center for updated information about the new *RSTOVRJRN operational value.
