CICS-IMS DBCTL environment

This figure summarizes the components of a CICS-DBCTL interface.

Figure 1 gives an overview of a CICS-DBCTL interface. Each box represents an address space running within a single MVS system. The marked area between the second CICS® and the first BMP is the point at which CICS components end and IMS components begin.
Figure 1. CICS-DBCTL interface
This figure summarizes the components of a CICS-DBCTL interface. All these components run within a single MVS system. On the CICS side, this is a CICS that can connect to DBCTL. On the IMS side: BMPs, an IMS (DBCTL) control region with a log and DEDB databases, DLISAS with DL/I full function databases, DBRC with a RECON data set, and an IRLM.

CICS-IMS DBCTL environment: description of components

The following topics give detailed information about each of the major components of the CICS-IMS DBCTL interface. See Summary of DBCTL components in CICS and IMS for an illustration of these components.
