Upgrading the CICS DB2 connection

This information enables you to plan and carry out installation or upgrade procedures in the CICS® DB2® environment.

CICS provides an attachment facility (the CICS DB2 adapter) that works with all supported releases of DB2. The CICS DB2 attachment facility is shipped with CICS Transaction Server and you must use this version of the attachment facility to connect a CICS region to DB2. Always use the correct attachment facility for the release of CICS under which a region is running.
