A given instance of CA MIM usually has one or more secondary or alternate control files in addition to a primary control file. If a file I/O error or other unusual event occurs on the primary control file, CA MIM switches to a secondary control file, assuming one is defined. If there are no other usable secondary control files defined and another error occurs, a product or system outage may occur.
This control file status health check periodically checks defined control files to determine if all are usable (can be written and read by CA MIM), and raises an exception if any allocated control file is not usable.
Monitor all allocated control files and ensure that all control files can be read and written to by CA MIM. This health check will alert you if one or more files is not usable.
