Before you can use the CICS-ICSF Attachment Facility, the ICSF system programmer, or the CICS administrator needs to install it. This involves:

• Relinking the ICSF enabling routine, CSFATREN, and the ICSF TRUE, CSFATRUE, if ICSF was previously installed in an environment without the CICS-ICSF Attachment Facility
• Installing the proper load libraries in the PROC used to start CICS
• Updating the CICS System Definitions (CSD) data set to define the programs to CICS
• Enabling these programs

For information about CICS TRUE programs, refer to CICS Customization Guide, SC33-1683.
