Using the XCOUPLE RELEASE command

You can use the XCOUPLE RELEASE command to remove the coupled HOLD status for a master session. In addition, the coupled status of each session is changed to NON-INTERLOCKED. Use caution when you issue this command.

The following is a list of cases where you would use the XCOUPLE RELEASE command:

• After you issue the XQUERY command with the MASTER option.
• After you issue the XADVANCE command for all sessions that do not indicate an RCV/ADV DELTA of zero (0) on the XQUERY MASTER report. The XADVANCE command recovers the data for these sessions to the master recoverable time.
• After you perform manual backups of secondary volumes as required by your system administrator.

In addition, if you issue the XCOUPLE command with either the DELETE or PURGE parameter for the last coupled session in a master session, XRC removes the coupled HOLD status for the master session.

If you couple the XRC sessions through a cluster session, and the cluster session is currently inactive, restart the cluster session. Be sure to do this before you run any XCOUPLE RELEASE command for any currently active XRC sessions that are already coupled through the cluster session. After the cluster session is restarted, issue the XCOUPLE ADD command for each of the sessions that were coupled through the cluster session. After the sessions are recoupled, issue the XCOUPLE RELEASE command. To determine the XRC sessions that have been previously coupled through the cluster session, issue the XSTATUS CLUSTER command.
