Using AR/CTL operational services

The following AR/CTL operational services are available:

• With checkpoint/restart services, AR/CTL offers a suspend-and-resume interface to other BMC Software products. Suspend-and-resume processing allows these products to obtain a point of consistency required for reorganization or recovery. For more information, see Using-AR-CTL-suspend-and-resume-interfaces.
• Early termination support allows you to terminate an application execution at a scheduled time of day (after a completed checkpoint) or on command at any of several points during program processing. You can obtain some early termination support services through the OCI and others through processing options. For more information, see Using-early-termination-support.
• An on-demand snap dump, available through the OCI, is a standard MVS snap dump of application program storage. You can use the snap dump to analyze application program problems. The snap dump does not cause program termination. For more information, see Using-on-demand-snap-dumps.
• Enhanced call tracing can help you develop, test, debug, and audit application programs. You can turn on enhanced call tracing with a processing option or with the OCI. To turn off enhanced call tracing, you can use the OCI or you can let tracing continue to the end of the job step. For more information, see Using-enhanced-call-tracing.

The operational services of AR/CTL are available through the operator communications interface (OCI), through processing options (in some cases), or both. The OCI consists of a set of MVS MODIFY commands you can issue from the MVS system console or on the console log.
