Architecture

CICS BAC consists of a number of components that work together to provide you with an effective control mechanism for sharing CICS® resources between CICS systems and your batch applications. These components are:

An outline diagram of all these components is shown in Figure 1.

Figure 1. Diagrammatic view of CICS BAC operating during normal CICS running. The replication of the broken lines round the CICS BAC request servers indicates that there can be more than one. For example, there could be one supporting an EXCI DPL request from a communication server and one or more EXCI DPL requests from batch request utilities. Note that this diagram does not show the file maintenance utility or the ISPF administration interface.
