Databases supported with DBCTL

Database Control (DBCTL) configuration of IMS supports all IMS full-function databases.

The full-function databases supported by DBCTL include:

Databases can be accessed through DBCTL from IMS BMP regions, as well as from independent transaction-management subsystems. Only batch-oriented BMP programs are supported because DBCTL provides no message or transaction support.

CICS® online programs can access the same IMS database concurrently; however, an IMS batch program must have exclusive access to the database (if you are not participating in IMS data sharing).

If you have batch jobs that currently access IMS databases through IMS data sharing, you can convert them to run as BMPs directly accessing databases through DBCTL, thereby improving performance. You can additionally convert current batch programs to BMPs to access DEDBs.
