Installation requirements for BMC AMI Application Restart Control
The BMC AMI Application Restart Control ( AR/CTL ) products for IMS, Db2, and VSAM have multiple requirements that you must meet before installing or using them.

Important If you plan to use AR/CTL in IMS-compatible mode (where IMS is not present during application program execution), no IMS license is required. When you migrate to a new release of IMS, IMS requires that all application programs complete normally under the old release before executing under the new release. When restarting a program on a new release, IMS cannot use a log data set that was created under the previous IMS release. Before you migrate to a new release of AR/CTL , ensure that all work completes normally under the old AR/CTL release. After migration, you cannot restart a job that terminated abnormally under the previous release. |
Storage usage in the private region | The amount of storage that AR/CTL uses in the private region varies during the execution of the job step and also varies depending on the application program environment and the services provided by AR/CTL . During initialization, AR/CTL uses about 2 MB of space in the private region; AR/CTL subsequently deletes most of the modules that were loaded during initialization. After initialization, AR/CTL uses approximately 627 KB of below-the-line storage when the application program begins to execute. More storage is required if the job step restarts or uses sequential files. |
