Setting Up Interpartition Communication and the SVC

DC/UCF resides in its own region/partition. Online application programs executed by using DC/UCF execute within the DC/UCF region/partition. Additionally, DC/UCF online compilers (such as the online system generation compiler), development tools (such as ADSA and OLM), and database procedures execute within the DC/UCF region/partition.

DC/UCF resides in its own region/partition. Online application programs executed by using DC/UCF execute within the DC/UCF region/partition. Additionally, DC/UCF online compilers (such as the online system generation compiler), development tools (such as ADSA and OLM), and database procedures execute within the DC/UCF region/partition.
Certain functions of the online DC/UCF system require the use of a special SVC which is supplied with DC/UCF software. In order to use these functions, the SVC must be installed from a release level at least as high as the online DC/UCF system. An SVC from a higher release level may be used to access a DC/UCF system at a lower release
Online applications executing under other DC/UCF systems, batch application programs, and programs executed under TP monitors other than DC execute in regions/partitions external to the DC/UCF region/partition. Since CA IDMS resides in the DC/UCF region/partition, all CA IDMS database requests issued by these programs and all responses must be passed across regions/partitions.
The remainder of this section describes the common communications architecture used to pass database requests from one region/partition to another and provides specific information on the following communications:
  • DC to DC
  • Batch to DC
  • CICS to DC
