Exit XSNEX
The purpose of XSNEX, in conjunction with its supporting sample programs, is to
provide a short-term migration aid. It is designed to give you time to modify those
application programs that have a dependency on the way CICS handles EXEC
CICS SIGNON and SIGNOFF before CICS TS 2.1, to enable them to work with the
current behavior.
Note: XSNEX is a migration aid only. You should consider removing all
application dependency on the old sign-on and sign-off behaviour.
There are no exit-specific parameters for this global user exit, which is invoked
whenever an application program issues an EXEC CICS SIGNON or an EXEC
CICS SIGNOFF command. You are not intended to write your own global user exit
program for this exit point. IBM provides DFH$SNEX, the sole purpose of which is
to make CICS handle EXEC CICS SIGNON and SIGNOFF commands in the same
way as in CICS TS 1.3 and earlier.
The supplied programs are:
DFH$SNEX
This user exit program is supplied in SDFHSAMP. The only function the
program performs is to set return code UERCPREV, which causes the security
domain to restore CICS behavior as in CICS TS 1.3 and earlier. You can enable
this user exit program using DFH$SNPI.
DFH$SNPI
This post-initialization program is supplied in SDFHSAMP. It issues an EXEC
CICS ENABLE PROGRAM('DFH$SNEX') EXIT('XSNEX') command to enable
the IBM-supplied user exit program, DFH$SNEX, in the final stages of CICS
initialization.
