Operating System

The minimum z/OS operating system is 1.10.

Virtual Storage

CA Technologies recommends using a region size of 4 MB or larger for each component.

Common Storage Area

CAISDI/med uses approximately 24 KB of the extended common service area (ECSA) for loading common storage resident services and intercepts. Certain types of service calls use approximately 100 bytes of ECSA while the service call is outstanding; however, CAISDI makes extensive use of cross-memory services to avoid the need for common storage areas.

CAISDI/els uses varying amounts of ECSA depending on which products use this component. The CAISDI/els Interface Controller reports the ECSA usage separately for each product defined to it.

IBM System Modification Program Extended (SMP/E)

All CAISDI components are installed using IBM SMP/E protocols and services. Periodic CAISDI maintenance updates are delivered in SMP/E-ready format as well.

APF-authorized Load Library Data Set

CAISDI requires an APF-authorized load library data set. This data set must reside on a shared DASD volume if it is to be accessed by multiple z/OS systems.

Link List

All CAISDI components must reside in the system link list. This gives all CA Technologies product common access to the interface modules.

Parameter Data Set

The CAI.CAW0OPTN and CAI.CAW0OPTV data sets contain the CAISDI initialization statements for all CAISDI components. If these are to be shared by multiple z/OS systems, they must reside on a shared DASD volume.

Event Library

The CAI.CAIEVENT data set is the repository for all the CAISDI/els event definitions. The event members are furnished by the CA Technologies products that use CAISDI/els.

CA Common Services Components

CAISDI uses other CA Common Services, such as CAICCI. These components must be installed and properly configured.
