XFCT

The XFCT system initialization parameter specifies whether you want CICS to perform file resource security checking, and optionally specifies the RACF resource class name in which you have defined the file resource security profiles.

XFCT={YES|name|NO}
If you specify YES, or a RACF resource class name, CICS calls RACF to verify that the userid associated with a transaction is authorized to access File Control-managed files. Such checking is performed every time a transaction tries to access a file managed by CICS file control. The checking is performed only if you have specified YES for the SEC system initialization parameter and specified the RESSEC(YES) option on the resource definitions. For further information on how resource security can provide a further level of security to transaction security, see Resource security for transactions.
Note: You can specify the XFCT parameter in the SIT, PARM, or SYSIN only.
YES
CICS calls RACF, using the default CICS resource class name of CICSFCT prefixed by F or H, to verify that the userid associated with a transaction is authorized to access files reference by the transaction. The resource class name is FCICSFCT and the grouping class name is HCICSFCT.
name
CICS calls RACF, using the specified resource class name, to verify that the userid associated with a transaction is authorized to access files referenced by the transaction. The resource class name is Fname and the grouping class name is Hname.

The resource class name specified must be 1 through 7 characters.

NO
CICS does not perform any file resource security checks, allowing any user to access any file.
