Introduction to 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 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:
  • Providing a single-system image approach to defining CICS resources.
  • Producing both local and remote instances of a resource from the attributes of a single definition.
  • Managing multiple versions of a definition; for example, as the application progresses from testing to production.
  • Generating multiple CICS connections from a single set of definitions.
Logical scoping
When 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. You can identify and refer to logically related resources as a set, regardless of where they 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 automatically at CICS initialization, or dynamically while a region is running. You can install a single resource in multiple CICS regions 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:
  • CICS BTS process types
  • Db2® connections and transactions
  • Document templates
  • FEPI nodes, pools, property sets and targets
  • Files and file key segment definitions
  • IPIC connections
  • LIBRARY resources
  • Map sets
  • Partition sets
  • Pipeline
  • Programs
  • Sysplex enqueue models
  • TCP/IP services
  • Temporary storage models
  • Transactions
  • Transient data queues
  • URI maps
  • Web services
Region property resources
These region property resources are the global resources that support the running of a CICS region:
  • Journals
  • Journal models
  • Local shared resource (LSR) pools
  • Profiles
  • Transaction classes
  • Terminals
  • Typeterms
Connectivity resources
These resources support the creation of connections between CICS regions and other systems:
  • Connections
  • Partners
  • Sessions
  • TCP/IP services
  • IP interconnectivity (IPIC) connections
