System Profile Exec

A system profile exec, named CICSTART, is issued before the first user exec is run after a CICS system restart. Usually, the system profile exec contains system customization commands, authorized sublibrary definitions, authorized user definitions, and authorized command definitions that must reside in an authorized REXX/CICS sublibrary.

The CICSTART exec is loaded from the first occurrence of the member CICSTART.PROC in the LIBDEF PROC search chain for the CICS partition.

Note:
The sublibrary in which the member CICSTART.PROC is found is treated as the initial authorized REXX/CICS sublibrary. This can then be changed using the SETSYS AUTHCLIB and SETSYS AUTHELIB commands.
