Defining DL/I support

CICS® can provide DL/I database support by using the IBM® Start of changeIMS™ Database Manager . For information about appropriate Versions and Releases, see the "CICS-IMS release compatibility" topic in the CICS IMS Database Control Guide .

You can use DL/I support with CICS through:

This section describes what you do to enable a CICS region to work with remote DL/I. For information about adding system and resource definitions for use with DBCTL, see the "Installing DBCTL, and defining CICS and IMS system resources" topic in the CICS IMS Database Control Guide .

The IMS libraries referred to in the job streams are identified by IMS.libnam (for example IMS.PGMLIB). If you use your own naming convention for IMS libraries, please rename the IMS libraries accordingly.

CICS provides a CICS-DBCTL interface which enables DBCTL, or IMS/ESA® or IMS/ESA DM/TM, to satisfy DL/I requests that are issued from the CICS region. New users should use this method because it is simpler than local DL/I to install and provides additional function. Details of installing and using DBCTL are in the CICS IMS Database Control Guide .

CICS support for access to DL/I databases using the IBM Information Management System (IMS) product is included in the base product, and no specific installation is required.
