Issue/Introduction

How do you setup FCT security in a particular CICS region without affecting other CICS regions running within the same CPU/LPAR? What is the impact of Top Secret CICS facility parameter RES/NORES and RESSEC=YES?

Resolution

If using FACMATRX=NO, the CICS SIT parameters control the CICS security including the RESSEC parameter on the PCT definitions.

To secure FCTs (DDNAME):

• Set XFCT SIT parameter to XFCT=YES
• and in the PCT RESSEC (YES)
• DSNCHECK CICS facility control option must be set to NO.

Only the CICS regions with the CICS SIT parameters set, will be impacted.

If using FACMATRX(YES), CICS security is controlled by the Top Secret CICS FACILITY control options (XFCT, XPCT, XPPT, etc) instead of the CICS SIT parameters.

Be careful when making changes to any of the Top Secret CICS FACILITY control options. All CICS regions sharing the same FACILITY name will be impacted by any changes to the Top Secret CICS FACILITY control options.
