Implementing BAS

This topic describes a route you could take to implement BAS on your CICSplex.

Creating migration form BAS

The first stage in the process of moving to using BAS is to migrate your resources from CICS® to CICSPlex® SM:

There are no resource assignments and, although you can now run your CICSPlex SM system perfectly satisfactorily, you will not be taking advantage of the special functionality offered by BAS.

Once you have extracted your CEDA definitions, you can proceed to migrate your resource definitions to full BAS function, as described in Migrating to the use of resource assignments.

Migrating to the use of resource assignments

You don’t have to migrate all your resources to resource assignments at the same time. You can identify certain resources in which you are interested, remove them from direct association with resource definitions, and create resource assignments (using the RASGNDEF object) for them. When you are happy with the resource assignments, you can move on to defining another set of resource definitions.

As you move towards processing your resource definitions more full-functionally, you should remove resource groups from direct association with a resource description and identify them instead in one or more resource assignments.

Note:
You can use the same resource description to manage both whole resource groups and selected resources identified in resource assignments. As you begin to take advantage of the resource assignment capabilities, you may have to update some of the underlying resource definitions. For example, a resource definition that was previously associated as is with a CICS system might require additional attributes before it can be assigned as both a local and remote resource in different CICS systems.

A recommended approach

When you decide to implement BAS functions in your enterprise, you should begin by defining the appropriate objects. This topic summarizes the preceding topics. You should:

Then, to create associations between these objects:

You can use the MAP action command to display a visual map of the BAS definitions in your data repository. If you want to see a list of the objects and associations you have already defined, use the RESINGRP view.

CICSPlex SM includes a Starter Set of CICSPlex SM object definitions that illustrates the concepts and components introduced in this chapter. The Starter Set is described in detail in The CICSPlex SM Starter Set.

If you have problems defining any particular object or association, refer to the CICSPlex SM Starter Set examples. The Starter Set includes BAS examples that you can use as models for your own objects. You can copy the supplied samples directly into your data repository via the batched repository-update facility. For more information about using the Starter Set as a model see the CICS Transaction Server for z/OS® Installation Guide. For more information about the batched repository-update facility, see CICSPlex System Manager Administration. The Starter Set definitions are listed in The CICSPlex SM Starter Set.
