Defining CICS system resources for DBCTL

Use this information to help you define system resources for DBCTL.

System initialization parameters
The CICS system initialization parameters contain information needed to initialize and control system functions and the initialization process.
PSB directories (PDIRs)
PSB directories (PDIRs) contain entries defining each PSB to be accessed using remote DL/I.
DD statements
You must put these two modules, which appear in the IMS.RESLIB library, in the CICS STEPLIB data set concatenation.
CICS-supplied groups within CICS system definition
Program, transaction, and mapset entries for the CICS system definition (CSD) file to provide DBCTL support are supplied in the group DFHDBCTL.
Log management
All DBCTL-related information is sent to the IMS log, not the CICS system log.
Monitoring control table (MCT)
If you were using local DL/I when converting to DBCTL, you can remove the entries for the DL/I event monitoring points (EMPs) from the monitoring control table (MCT).
Program list table (PLT)
To connect CICS to DBCTL at CICS startup time, you can invoke it in the second stage of program list table postinitialization (PLTPI) processing (that is, the third stage of CICS initialization).
Transient data queues
You need a definition for the CDBC transient data queue. The CDBC transient data queue is used for messages issued by the CICS-DBCTL interface.
