Downward Compatible Libraries and Databases

If you have several CA View databases in your operating environments, use the CA View Release 12.2 target libraries for online access to supported release databases until you version the databases up to CA View Release 12.2. You can also archive and reprint reports and bundles from CA Deliver supported releases.

Note: To use the new features, upgrade your database to CA View Release 12.2.

Business Value:

Downward compatibility with earlier release databases eliminates the need to upgrade immediately all of the databases simultaneously. Downward compatibility lets you upgrade databases on your own schedule, back up database versions, and minimize system downtime.

Considerations:

• When your CA View databases reside on multiple logical partitions (LPARs), upgrade target libraries to CA View Release 12.2 before upgrading databases to CA View Release 12.2. You can update databases independently of each other.
• To access previous release databases, use CA View Release 12.2 Interactive System Productivity Facility (ISPF) and Time Sharing Option (TSO) CLIST programming language.
• The CA DRAS Release 12.2 task can access CA View Release 11.7, CA View Version 12.0, CA View Release 12.1, and CA View Release 12.2 databases. If you versioned your CA View database to the most recent version, verify that your CA DRAS task is using the most recent libraries.
• The CA View Release 12.2 cross-memory task can access CA View Release 11.7, CA View Version 12.0, CA View Release 12.1, and CA View Release 12.2 databases.
• You can perform direct archival to CA View Release 12.2 using CA Deliver Release 11.7, CA Deliver Version 12.0, CA Deliver Release 12.1, and CA Deliver Release 12.2.
• To determine the EBC modules to load during CA View and CA Deliver execution, use CAHCRLSE. Place CAHCRLSE in the first library in the STEPLIB or LINKLST concatenation.
• CAHCRLSE is the EBC release level module that ships with the latest level of either CA View or CA Deliver.

  The EBC modules are release compatible; you can use the latest level with supported CA View and CA Deliver releases.
