CDBM - database control interface

Use the CDBM transaction to issue DBCTL operator commands from a CICS terminal. CDBM is applicable only to CICS systems using the IMS Database Control (DBCTL) interface.

CDBM also provides a means of maintaining a command file which stores commands. You can store commands for any reason, but repeated reuse is likely to be a frequent purpose. These stored commands can include more databases than the operator transaction panel has space for.

To use CDBM you must:
  1. Have a DBCTL system running IMS V9.1 or later
  2. DBCTL must have the AOIS parameter set to a value other than N. If values A, C or R are used, appropriate security controls must be used to allow the CICS-DBCTL interface to operate.
  3. Generate and add to the DBCTL system, a PSB named DFHDBMP.

For detailed information about the CICS-DBCTL interface and guidance on using the CDBM transaction with databases controlled using DBCTL, see Overview of Database Control (DBCTL).

Note: The CDBM transaction uses basic mapping support (BMS) and therefore this function is available only through those terminal devices that are supported by BMS.
