Restarting an inactive XRC coupled session

You can use the following procedure to restart inactive XRC sessions. Issue the XQUERY MASTER command to determine if an XRC session is inactive. The session status of END, UNK, or SUS on the ANTQ8304I message indicates that a coupled XRC session is inactive. You can issue the XQUERY SUMMARY command on the system from which the XRC session is running to determine if the session is active.

To restart inactive XRC sessions, perform the following tasks:

  1. Issue the XADVANCE command for all sessions that indicate that the RCV/ADV DELTA time is positive (that is, the session consistency time is consistent with the master journal time). You must issue the command on the system on which the session was running.
    Note: After the XADVANCE command successfully completes, the data on the secondary devices is consistent with the master journal time. You can now create backup copies of your secondary devices as indicated by your installation backup procedures.
  2. Issue the XSTART command for each session.
  3. Issue the XQUERY MASTER command (and the XSTATUS CLUSTER command if sessions are coupled through a cluster session).
    Note: You must perform steps 1 through 3 for each inactive session before issuing the XRELEASE command.
  4. Issue the XCOUPLE command with the RELEASE option if the ANTQ8306I message indicates that the master session is in HOLD status. (See What to do if a session is in COUPLE_FAILED status for additional information regarding the HOLD status for a master session.)
  5. Issue the XADDPAIR command for each pair in the session. If volume pairs are in the SUS state (suspended), you can use the SUSPENDED option of this command to add all of these volume pairs again.
