Checking BRMS Network Synchronization

The System status field on the Change Network Group display should provide you with an easy means of determining whether the current system is communicating with the other networked systems. A status of Online indicates that synchronization is running between the two systems. A status of Offline may be an indication of a problem.

Note:
Network Status only indicates whether the system has or has not been activated into the network.

You can take the following steps to run a daily check of media synchronization:

  1. On one system in the BRMS network, create a dummy media class (for example, NETCHK, which stands for Network Checking). Because you will not use this media class for real backups, you can simply use the default values.
  2. On each system (SYSTEMxx, where xx = name of the system), type: ADDMEDBRM VOL(SYSxx) MEDCLS(NETCHK)
  3. Every morning, on each system in your BRMS network, use the job scheduler to run the CL command:

    RMVMEDBRM VOL(SYSxx) MEDCLS(NETCHK)

    Delay Job (DLYJOB) DLY(300)

    ADDMEDBRM VOL(SYSxx) MEDCLS(NETCHK).

  4. After you submit the CL command, your media should have a creation date equal to the current date. This should be true on the system that will run the command. If not, it means that you did not submit the CL command, and should check the job log for error information. The other systems in the BRMS network should also have the current date as the creation date for this media. If not, it means that system did not process the update correctly.

Assuming that the current date is July 6, 2005, the WRKMEDBRM command for each system should display the following information:
