You can use group monitors when you want multiple monitors to participate in a decision or when you want to coordinate activity among multiple monitors. One use of a group monitor is in a switching scenario. You can define several monitors to watch communications links or objects on your production system. At any moment, if all participating communications monitors (a sub-class of an interval monitor) agree that the system is not active, the group monitor is triggered. The event program for the group monitor can be programmed to use the built-in switching capabilities of MIMIX to switch users to a backup system and switch the direction of replication. A sample event program MSFEVENT is shipped with this product and is in file MMTEMPLSRC in the product library.
