Changing MFS formats

You can use the online change COMMIT command to change MFS formats without stopping related activity (messages can be queued and scheduled while you change an associated MFS format block).

But you should coordinate changing MFS formats and message queuing so that problems do not occur.

In the IMS™ DB/DC and DCCTL environments, the online change PREPARE command does not stop the queuing of related messages when you change MFS formats.
