Introduction to CICSPlex SM BAS

Business Application Services is the component of CICSPlex® SM that is responsible for managing the CICS® resource definition and installation process for business applications at your enterprise.

Business Application Services provides the following facilities:

Centralized resource definition
With BAS, you can implement CEDA-like resource definition and association across the entire CICSplex. The CICSPlex SM data repository (EYUDREP) can serve as the central repository for CICS resource definitions. CICSPlex SM minimizes the number of resource definitions you need for your CICSplex by:
Logical scoping
Once your CICS resources are defined to CICSPlex SM, you can monitor and control those resources in terms of their participation in a named business application, rather than their physical location in the CICSplex. Logically related resources can be identified and referred to as a set, regardless of where they actually reside at any given time.
Distributed resource installation
Resources that are defined to CICSPlex SM must still be installed in the appropriate systems, either by CICS or CICSPlex SM. You can use BAS to install your resources either automatically, at CICS initialization, or dynamically, while a system is running. A single resource can be installed in multiple CICS systems either locally or remotely, as appropriate.

Business Application Services supports the following CICS resources:

Application resources
These are the resources that support the business applications at your enterprise. They are the resources that an application requires to run:
Region property resources
These are the global resources that support the running of a CICS system:
Connectivity resources
These are the resources that support the construction of intersystem communication (ISC) and interregion communication (IRC) links between CICS systems:
