Startup Activities

CA MIM is designed to run on two or more systems sharing a common control file, therefore, it does not synchronize unless at least two systems are communicating with the control file. An exception is made for cases where all eligible systems have been FREED from the control file, in which case, it is possible for a single system to start up and synchronize.

If you want to start a single system for test purposes, be sure to include a DEFSYS statement in the initialization member, and define a second system on the DEFSYS statement. When the starting system reaches “PENDING” status, issue a FREE command. On the FREE command supply the name of the second system for the SYSNAME parameter. If you use a REMOVE command instead of a FREE command, then the system does not reach synchronization, because it appears that the second system was never defined.
