Description:

Upgrading to IDMS R18.0 requires special handling for user configurable tables as their implementation has changed.

Solution:

CA IDMS v18.0 introduced changes into how user configurable modules and "named" exits are managed. Thus most will need to be reassembled/linked when upgrading to v18.0 or 18.5 directly from an earlier release. See 18.0 Release Notes chapter "Separation of User-Configured Modules" for details. Here is a summary of how various modules need to be treated on the upgrade:

  1. SYSIDMS does not need to be reassembled.
  2. RHDCSRTT probably doesn't need to be reassembled, but we recommend assembling it using the updated software.
  3. CTABGEN, UTABGEN, etc definitely must be recreated using the new method because they have changed significantly. Prior to 18.0 CTABGEN was linked with RHDCMT00. In 18.0 and 18.5 it is a standalone load module. The same is true for UTABGEN, which was previously linked with IDMSDDAM and is now a standalone load module. The SECURITY ADMIN Guide has assembly/Link JCL examples for these modules.
  4. Any customized user table or exit that was previously linked with some IDMS processing module is now a separate standalone module and should be re-linked for these releases. See 18.0 Release Notes chapter "Separation of User-Configured Modules" for details.
