Upgrading to Version 18.0 › Execution JCL Changes

Execution JCL Changes

In most cases, no changes are required to CA IDMS execution JCL. However, the following conditions require updating JCL to upgrade to CA IDMS 18.0 successfully:

• You may need to increase the region size to accommodate increased storage requirements.
• To enable CA IDMS Task Analyzer and CA IDMS Masterkey for a CV, you must include new SYSIDMS parameters in your startup JCL. These replace the need for adding CA-supplied exit routines for these products to your RHDCUXIT module.
• You may need to change the STEPLIB and CDMSLIB library concatenations to include additional data sets or to update the data set names to reference the 18.0 libraries.
  • All customized load modules created during configuration are placed in a dataset referred to as your custom load library [your.custom.loadlib]. This dataset must be placed in the library concatenation list before the standard CA IDMS deployed load library [yourHLQ.CAGJLOAD] in all execution JCL.
  • Uppercase modules are deployed into a library separate from other CA IDMS load modules. If you need to use the uppercase character set, the uppercase load library [yourHLQ.CAGJLMDU] must be placed in the concatenation list before the standard CA IDMS deployed load library [yourHLQ.CAGJLOAD] in all execution JCL.
