Automation of the Installation for the DB Subsystem

In Version 14.0, enhancements were made to simplify, for z/OS users, the CA Datacom install and usage. This includes removing the need for a CA Datacom SVC and the CA Datacom subsystem that had to be manually installed. The changes include the following:

• A new Program Call PC routine, DBPCCPR, was built to support Version 14.0 normal MUF requirements. CAIRIM installs DBPCCPR during the IPL process, or later. If DBPCCPR is not installed at the time of the first MUF execution, MUF dynamically does the install, creating a PC number for Version 14.0. DBPCCPR supports all MUF functions, basic DBUTLTY functions, and MUF user interface requirements.
• MUF does not use the old PC subsystem, and therefore it can be removed after Version 14.0 is the only, or oldest, CA Datacom release executed on the system. The old subsystem is present if the DBUTLTY function REPORT AREA=MVS prints the line: CA DATACOM/DB SUBSYSTEM IS PRESENT. The old subsystem is also represented by the modules being displayed of DBESPPR and DBSSPPR.
• MUF does not use a CA Datacom/DB SVC. The current release interface does not use the CA Datacom/DB SVC. The SVC should not be installed because it exists only in case of some future requirement that is not expected.
• A new Program Call PC subroutine has been built that is subordinate to the CAMASTER Subsystem to support special requirements. Those special requirements include the use of XCF communications and RRS for two-phase processing. CAIRIM installs the DBPCSPR routine during the IPL process, or later. If not installed by CAIRIM, there is no support for XCF and RRS. CAMASTER is part of CA Common Services for z/OS.

Production and Test Subsystem and Subroutine Support

When Datacom used an SVC it was possible to have two. One SVC could be used for production and one could be used for testing rare changes to the SVC. Most users never had this requirement even for the rare changes as they waited until the change was confirmed and provided with normal maintenance.

The subsystem and subroutine have a similar need but do not have the SVC number strategy. To provide the equivalent, the ability was built to allow a Production version to be installed for normal use and also a Test version installed for testing the rare changes. Most users should not require the Test version.

You can select the Production or Test version by using the keyword PC= in the DBSYSID Macro used to generate the DBSIDPR and related modules. Specify PC=PRODUCTION or PC=PROD (the default) to request the Production Subsystem and subroutine. Specify PC=TEST to request the Test Subsystem and subroutine. This option applies to the set of both DBPCCPR and DBPCSPR.
