XAPPC

The XAPPC system initialization parameter specifies whether RACF® session security can be used when establishing APPC sessions.

XAPPC={NO|YES}
Valid values are as follows:
NO
RACF session security cannot be used.
YES
RACF session security can be used.

If you specify BINDSECURITY=YES for a specific APPC connection, a request to RACF is issued to extract the security profile. If the profile exists, it is used to bind the session.

Note: If you specify XAPPC=YES, the external security manager that you use must support the APPCLU general resource class, otherwise CICS® fails to initialize.
Restriction: You can specify the XAPPC parameter in the SIT, PARM, or SYSIN only.
For information on how resource security can provide a further level of security to transaction security, see Resource security for transactions.
