There are several internal functions in which CICS behaves like an application
program, but is actually performing housekeeping functions that are not directly
for any end user. The associated transactions execute under control of the
CICS region userid, and because they access CICS internal resources, you must
give the CICS region userid authority to access them. These are:
- CICS system transactions
CICS needs authority to attach all the internal
housekeeping transactions that it uses. See Category 1 transactions.
- Auxiliary userids
If CICS surrogate user checking is specified with
the
XUSER system initialization parameter (the default), CICS needs authority
to use certain additional userids. These are:
- Resources used by PLTPI programs
If the PLTPIUSR system initialization parameter is omitted, the CICS region userid is used for all PLTPI
programs. In this case, give the CICS region userid access to all the CICS
resources that these programs use. See PLT programs.
