The Teradata program called DBCCICS, the long‑running CICS Interface transaction for accessing the Teradata Database, provides storage and context management services for CICS transactions (both conversational and pseudo‑conversational) that access the Teradata Database.

During initialization of the CICS Interface, DBCCICS loads both CLI and preprocessor runtime code. All CICS transactions for the Teradata Database, whether they use CLI directly or language preprocessors, share a single copy of this code.

CLI uses CICS “shared” storage for its control blocks and data buffers. For pseudo‑conversational applications, session and request context are automatically preserved across pseudo-conversational boundaries. This memory is released by the CICS Interface upon termination of the pseudo-conversation or transaction abend.

The four‑character transid for DBCCICS is DBCC.
