You have an IMS data sharing environment, in which you are running
multiple CICS systems that are data sharing with one another and with batch, and
all the data sharing is taking place within a single-MVS environment. In this
case, you could consider migrating completely to a single DBCTL within an MVS image
instead of using data sharing. If you do this, migrate all the DL/I batch
jobs involved to BMPs, which will simplify log management.
You can use IMS data
sharing across multiple DBCTLs in a single- or multi-MVS environment.
