Defining DL/I support

CICS® can provide DL/I database support by using the IBM® IMS Database Manager.

For information about appropriate versions and releases, see Overview of Database Control (DBCTL). As they become available, versions of IMS newer than those versions listed are also compatible.

You can use DL/I support with CICS through these methods:
  • Database control (DBCTL)
  • CICS remote DL/I support, also known as function shipping

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, rename the IMS libraries accordingly.

CICS provides a CICS-DBCTL interface which enables DBCTL, IMS, or IMS DM/TM to satisfy DL/I requests that are issued from the CICS region. This method is simpler to install than local DL/I and provides additional function. Details of installing and using DBCTL are in Installing and generating DBCTL.

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