Connection, disconnection, and inquiry transactions for the CICS DBCTL interface
There are two CICS® transactions that you can use to connect to, disconnect from, and inquire on the status of the CICS-DBCTL interface.
They are:
- CDBC, which enables users
(for example, CICS operators and network controllers) to display
a menu to connect to and disconnect from DBCTL.
- For connection, CDBC issues a DBCTL connection request
to DFHDBAT, which issues a DRA INIT request internally to the DRA.
CDBC also enables you to override the DRA startup parameter table suffix and DBCTL identifier when you are connecting CICS to DBCTL. (See Defining the IMS DRA startup parameter table for information on the contents of the DRA startup table.)
- For disconnection, CDBC can issue an orderly or
an immediate disconnection request to DFHDBAT, which issues a DRA
TERM request internally to the DRA.
(See CDBC transaction for connect and disconnect for more information on using CDBC.)
- For connection, CDBC issues a DBCTL connection request
to DFHDBAT, which issues a DRA INIT request internally to the DRA.
- CDBI, which enables users to inquire on the status of the CICS-DBCTL interface. See CDBI transaction for inquiry for more information.
You can enter CDBC and CDBI from either a CICS terminal or an MVS console. You can restrict access to these transactions using transaction security. Messages from CDBC can be sent to the transient data destination CDBC.
