It is recommended to install SSCM with IMON.
SSCM V21.0 is delivered with the following files:
the module library SYSLNK.SSCM.210, which contains the SSCM object module
the system syntax file SYSSDF.SSCM.210 containing statements for SSCM
the user syntax file SYSSDF.SSCM.210.USER containing statements for SSCM
the procedure SYSPRC.SSCM.210, which SSCM starts by means of START-PROGRAM
the subsystem declaration file SYSSSC.SSCM.210
the message file SYSMES.SSCM.210
the REP file SYSREP.SSCM.210 (if present)
Before you can install SSCM V21.0, it is first necessary to satisfy the following conditions:
The SSCM subsystem definition must be entered in the subsystem catalog.
The SYSLNK.SSCM.210 library must be cataloged under the installation user ID that was named with ADD-CATALOG-ENTRY or SET-SUBSYSTEM-ATTRIBUTES when SSCM was entered in the subsystem catalog (by default, this is the system user ID whose files generally begin with “$.”).
The SSCM subsystem is activated by means of the command START-SUBSYSTEM SSCM and it is started by means of the command START-SSCM.
This subsystem also includes the message file, the syntax file and the REP file, which are activated automatically. The system syntax file SYSSDF.SSCM.023 must have the attribute SHARE=SPECIAL.
If the procedure SYSPRC.SSCM.210 is used to call SSCM V21.0, points 1 and 3 cease to apply.
Coexistence of SSCM versions
SSCM versions V1.0 to V21.0 can be defined simultaneously in the system catalog. The version can be selected with the SELECT-PRODUCT-VERSION command. The START-SSCM command then starts the selected version.
For information on compatibility and portability between the various BS2000, SSCM and DSSM versions see "Version dependencies between BS2000, DSSM and SSCM".
