# IMS DB/DC Not Suitable for Batch programs, why

---

The interesting point is DB/DC does contain both transaction manager and database manager. So this region supports to CICS [to access IMS](https://srinimf.com/2015/10/06/how-to-access-ims-db-database-using-sql-queries1-of-2/) database. Except BATCH it supports for all kinds of transactions.

## Batch Jobs

Note: Pure BATCH runs under MVS address space. So BATCH jobs cannot access IMS database, unless they used as BMP (Batch).

## Online Transactions

DBCTL- Since this region does installed only database manager. It supports for CICS programs and [BMP batch](https://srinimf.com/2015/10/31/bmp-transaction-oriented-jcl-in-ims-db/) programs. Also for [DB2 stored procedure](https://srinimf.com/2013/03/24/db2-how-to-access-cics-from-db2-stored-proc/)s through ODBC.

DCCTL – It does support for BMP,MPP, and IFP programs. Since this region does installed only transaction manager.

Please note that BATCH, BMP(BATCH) and BMP(txn) all are different.
