If you are upgrading your existing CA Datacom products from Version 14.0 to Version 15.0, some pre-installation considerations apply directly to upgrades. To determine if there are more requirements, see the README File.
The upgrade process is intended to be performed in multiple phases.
This program is used to determine the status of your Datadictionary database and should be executed against each multi-user region before beginning the upgrade. Member ADSDC14 in the CABDSAMP library contains sample JCL to perform this step. For information about running this utility, see the CA Datacom/DB Datadictionary Batch User Guide.
This phase is optional but highly recommended. Additionally, you can use this phase for initial testing.
This phase can be used for initial testing.
You can continue to run CICS and batch regions that are still at the 14.0 level against this multi-user. This phase allows you to test the following against a multi-user at 15.0 with minimum impact if a fallback to 14.0 is necessary:
This upgrade can be fully performed against the 15.0 multi-user with no need to recycle the multi-user or close the Datadictionary or DDD databases. You can still continue to execute 14.0 level batch and online against the 15.0 multi-user.
If you have multiple CICS regions executing against the Multi-User Facility (MUF), you do not have to upgrade them all simultaneously. Both the 14.0 and 15.0 level CICS regions can run against the multi-user at the 15.0 level.
Note: Each of these phases can last for any length of time from minutes to months.
