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.

Installation considerations for BMC AMI Application Restart Control products

The following table lists the requirements for the AR/CTL products:

Oops, it seems that you need to place a table or a macro generating a table within the Table Filter macro.

Requirement type	Description
CICS	If you are installing AR/CTL for VSAM, your site must have a licensed copy of the IBM CICS product or CICS Transaction Server product in order to use remote VSAM access services in a batch VSAM application program. AR/CTL is supported for use with all IBM-supported versions and releases of CICS and CICS Transaction Server.
CSA/ECSA usage by the BMC Primary Subsystem (BMCP) and the BMC Consolidated Subsystem (BCSS)	The BMCP and the BCSS use less than 64 KB in nonextended common storage and use 1.5 MB in extended common storage. Most BMCP and BCSS private storage requirements (non-CSA) are obtained from extended private storage. The BMCP and the BCSS place work areas above the 16-MB line when possible. These subsystems are compatible with DFSMS and are not sensitive to Data Facility Product (DFP) levels. BMCP requires 22 KB of above-the-line storage on each z/OS system on which it runs. BCSS requires 1771 KB of above-the-line storage on each z/OS system on which it runs.
Db2	If you are installing AR/CTL for use with Db2, your site must have a licensed copy of Db2. The AR/CTL Db2 plan, ARCTLP$3, must be bound (and execute authority must be granted) on each Db2 subsystem where application programs use automatic checkpoints by a trigger cursor or automatic cursor repositioning. Use the same plan name, ARCTLP$3, for all Db2 subsystems. AR/CTL is supported for use with all IBM-supported versions and releases of Db2.
IMS	Your site must have a licensed copy of the IMS Database Manager product in either of the following cases: If you want to use the BCF component of AR/CTL If you plan to use AR/CTL with IMS AR/CTL and the BCF component are supported for use with all IBM-supported versions and releases of IMS. 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.
