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:
- SYSIDMS does not need to be reassembled.
- RHDCSRTT probably doesn't need to be reassembled, but we recommend assembling it using the updated software.
- 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.
- 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.
