Batch data streams supported by CICS

CICS supports additional Batch Data Streams (BDS) to work with z/OS® data sets.

The Batch Data Stream (BDS) framework provides several pre-built patterns to work with streams such as text, byte, database, and z/OS data sets. You can implement an interface where the business logic for processing the stream is added. The pre-built patterns manage actions such as opening files, closing files, and externalizing and internalizing checkpoints.
