Physical Control File Communication Methods

This product supports the use of physical DASD files communication between systems. The CA MIM control file is allocated on a shared DASD volume. Individual CA MIM systems access the control file to communicate managed resource activity to other systems.

You can, at any given time, have 100 control files that are allocated for use by CA MIM. However, only the current control file is used for global communications. During a hardware or software failure, CA MIM automatically migrates to an alternate physical control file.
