Setting Up System Registry › System Types

System Types

Each system registry entry is one of four different system types. Two reflect real systems, and two are CA CSM-defined constructs used to facilitate the deployment process. The two real system types are non-sysplex system and sysplex systems. The two CA CSM-defined system types are shared DASD clusters and staging systems.

Non-Sysplex Systems

Specifies a stand-alone z/OS system that is not part of a sysplex system.

Note: During system validation, a non-sysplex system can be found to be part of a sysplex. You are notified and you can have the system automatically added to the sysplex that it is a part of. This action can cause the creation of a new sysplex system. If you do not select the automatic addition to the appropriate sysplex, this system is validated and cannot be deployed.

Sysplex or Monoplex Systems

Specifies a sysplex (system complex), which is the IBM mainframe system complex that is a single logic system running on one or more physical systems. Every physical system that makes up a sysplex is often referred to as a member system.

A monoplex system is a sysplex system with only one system assigned.

Note: Monoplexes are stored in the sysplex registry tree but with the name of the monoplex system and not the monoplex sysplex name. For example, you have a system XX16 defined as a monoplex, with a sysplex name of LOCAL. The system is depicted in the system registry as a sysplex with the XX16 name. This sysplex contains one system: XX16.

This system type can help you if you have monoplexes with the same sysplex name, for example, LOCAL. The system registry shows the actual monoplex system name at the top-level sysplex name.

Shared DASD Clusters

Specifies a shared DASD clusters system, which defines a set of systems that share DASD. This system can be composed of sysplex systems, non-sysplex systems, or both. A staging system cannot be part of a shared DASD cluster.

Staging Systems

Specifies a staging system, which is an SDS term that defines a virtual system. A staging system deploys the deployment to the computer where the CA CSM driving system is located. To use a staging system, the CA CSM driving system must be registered in the CA CSM system registry.

A staging system can be useful in testing your deployments and learning deployment in general. This system can also be used when your target systems are outside a firewall. For example, deploy to a staging system and then manually copy the deployment to tape.

Note: You cannot use CA CSM to configure a product to a staging system.
