Components of the DB2 UDB Option for CICS  Host request library DB2 table

Chapter 1: Understanding the DB2 UDB Option for CICS

Transaction processor AMD2

AMD2 is the default name of the CICS transaction in the DB2 UDB Option for CICS that allows clients to submit SQL statements to DB2 or RSP requests.

NoteA separate installed CICS region with AMD2 is required for each DB2 subsystem accessed.

DirectConnect invokes AMD2 when it sends a client SQL request to the mainframe. AMD2 then submits the SQL request to DB2, using the DB2 dynamic SQL facility.

AMD2 returns DB2 results and messages to DirectConnect and then terminates. However, in the case of long transactions or allocation on connect, AMD2 terminates only after the client explicitly ends the transaction.
