Steps for Modifying DSN3SATH

  1. For RACF sites: Modify DSN3SATH as shown in Modifying DSN3SATH. This section contains a portion of DSN3SATH, illustrating the correct location of the modifications.

    2. For CA-TOP SECRET sites: You must obtain the DSN3SATH usermod from the Optional Materials file of the CA-TOP SECRET product tape. Apply the CA-TOP SECRET usermod. Then modify DSN3SATH as shown in Modifying DSN3SATH.

    Note: The CA-TOP SECRET modifications will add a new instruction in the same location as the CALL FOCDSN4 line. The CALL FOCDSN4 insertion should be made following this new instruction:

    L   R6,X'BO'(,R6)                  @USER

    As of CA-TOP SECRET Release 4.3 Genlevel 9301, the DSN3SATH usermod is no longer required, and the application of the usermod as described above should be omitted.

    For CA-ACF2 sites: CA-ACF2 provides a sample, customized DSN3SATH exit on the CA-ACF2 tape (Release 5.1 or higher) or on PTF78210. Computer Associates, Inc supplies this PTF tape. The sample exit supplied by Computer Associates should be used in this case, rather than the IBM sample exit. FOCDSN4 should not be used with CA-ACF2.

  2. Assemble and link-edit the modified DSN3SATH (AMODE31,RENT) into a module with entry point DSN3@ATH and name DSN3@ATH. Sample JCL is provided.

  3. Copy the module into the DB2 exit library (usually DSN230.DSNEXIT).
