Using Exit Programs › URT Selection (DCCTFPR)

URT Selection (DCCTFPR)

Before accessing CA Datacom/DB, CA Datacom CICS Services passes control to the URT (URT) selection module (DCCTFPR). This module contains logic to determine which URT CA Datacom CICS Services should use when processing a request. Use this standard selection, unless you require site-specific security, accounting, or a pre-CA Datacom/DB access exit. You can modify the standard URT selection by prefixing DCCTFPR with an exit routine or you may replace DCCTFPR with your own URT selection logic. Replacement and suffix exits are no longer allowed.

Note: If you currently have a suffix exit or a replacement exit, contact CA Support to aid you in writing a prefix exit or eliminating the user exit completely. There are methods available in the pre-exit to accomplish the suffix condition.

Prefix exits are the most common type of exit. They are used primarily to alter the DBID prior to finding a valid URT based on USERID or application/transaction/terminal. The suffix exits are used to modify which URT is used after it was selected based on USERID or application/transaction/terminal. These are no longer supported. However, most of the functions can be accomplished in prefix exits using global URTs.
