Summary :
This SAP note guides on migrating DB2 connectivity in an SAP system from the DB2 runtime client to the DB2 CLI driver. For SAP systems on Basis 7.00 with DB2 9.1 or later, this transition offers several benefits: no local installation is necessary, simplifying maintenance with centralized connection data management. The CLI driver allows dynamic replacement while servers are running, which is not feasible with runtime clients. It requires DB2 CLI driver installation on the database server, updates to the SAP kernel, and modification of start profiles. It finishes with configuring and migrating connection settings to the centralized DB2 CLI configuration file.
