From the article “V5R4 and PTFs Provide New Automatic Journaling Capabilities” that was included in the October 24, 2007, issue of this newsletter (article ID 55791 at SystemiNetwork.com):
“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.”
