Using logical scopes to control application resources

Business Application Services enables you to monitor and control CICS® resources according to their purpose and logical relationships within your enterprise. For example, rather than viewing the resources in one or more CICS systems or CICS system groups, you can display all the resources that are currently defined as being part of a business application. This allows you to specify a logical scope for CICSPlex® SM requests, rather than a physical scope that is location-dependent and subject to change.

A business application can be any set of resources that represent a meaningful entity to the users in your enterprise. The resources can exist in any CICS system in the CICSplex. If the resources are defined to CICSPlex SM, Business Application Services can locate them and manage them regardless of what platform or release of CICS they are defined to.

For a business application to be recognized by CICSPlex SM, you must assign it a logical scope name in a resource description. When you create a resource description, you identify the resource definitions that make up your application and the CICS systems with which the application should be associated.

Note:
The concept of a business application is independent of the CICSPlex SM resource installation capabilities. Even CICS systems that do not support resource installation can be included in a business application to be managed by CICSPlex SM.

To identify a set of resources as an application, you must:

  1. Define the resources to CICSPlex SM using the Business Application Services resource definition views.
  2. Create one or more resource groups (RESGROUP) and add the resource definitions to them.
  3. Create a resource description (RESDESC) and specify a name to be used as the logical scope.
  4. Decide how you want the resource definitions to be processed and then do one of the following:

Once an application has been identified to CICSPlex SM as a logical scope, you can specify that name on any CICSPlex SM end-user interface or API request that honors a scope value.

Note:
A logical scope name is not a valid scope for resources that cannot be defined by BAS (such as system dump codes). However, a logical scope name is valid for CICS Regions (CICSRGN) and Runtime MAS display (MAS) views, which will display the regions that may contain resources in the named logical scope.
