Register journals in an EXCTG
When performing Continuous Access Journal Z copy operations between multiple primary and
secondary storage systems, you must register the journals in an EXCTG.
Prerequisite information
•
Set up primary and secondary EXCTGs using Business Continuity Manager prior to registering
journals.
•
journals must be in Active or Stopped status.
•
Register master and restore journals in the separate EXCTGs.
•
When Continuous Access Journal Z pairs are cascaded with Business Copy Z, and the Business
Copy Z T-VOL and a Continuous Access Journal Z P-VOL share the volume, data consistency
cannot be maintained when between primary and secondary systems, even when journals
are registered in an EXCTG.

When Continuous Access Journal Z pairs are cascaded with Continuous Access Synchronous

share the volume, make sure you enable the time stamp transferring option of all the Continuous
Access Synchronous Z pairs in the journal for data consistency.
