Critical value in main.cf - Veritas Cluster Server

This is a discussion on Critical value in main.cf - Veritas Cluster Server ; Sorry for asking such a stupid question: If the 'Critical' value for a resource in main.cf is set to 0, in the event that this resource fails will the value being 0 determine that a failover will occur?...

Thread: Critical value in main.cf

  1. Critical value in main.cf


    Sorry for asking such a stupid question:

    If the 'Critical' value for a resource in main.cf is set to 0, in the event
    that this resource fails will the value being 0 determine that a failover
    will occur?

    Let's say you have a service group for Oracle. You include the
    diskgroup, volumes, mount point(s), IP address, Oracle application and
    listener.

    You also have aother program that runs and reports on the number of
    users connected to Oracle (and if this gets above a certain number, you
    page your DBA).

    If a resource is marked as Critical (thus Critical = 1), which is the
    default (so even ifyou don't see anything in the main.cf , it is set to
    1), if this resource fails, the service group will fail over.

    Example:

    If Oracle fails, you want the service group to fail over to the other
    machine(s) in the cluster.

    The last "monitor" program is not critical to the Oracle application.
    Thus, if this monitor fails, you don't want the whole thing to fail. So
    the monitor would be marked as "Critical = 0"



    In short, if any resource in the service group is marked as Critical,
    the service group will fail-over if that resource fails
