Applications written to use DSN-less connections (the SQLDriverConnect API and the DRIVER connect string keyword) should be updated to use the "iSeries Access ODBC Driver" name. The older "Client Access ODBC Driver (32-bit)" name is deprecated. This information is also described in the Addendum to V5R2 readme.txt available on the iSeries Access Web site and in the OS/400 V5R2 Memorandum to Users. All File DSNs should be deleted and re-created. Although they can be used with V5R2 iSeries Access, future versions of iSeries Access may not support the old driver name. No action by the user is required.įile DSNs are not migrated (even if edited). Existing ODBC User and System datasources (DSNs) that were created with Client Access are migrated automatically the first time the DSN is used. Selecting either driver name creates a DSN with the new "iSeries Access ODBC Driver" name. The preferred method for creating new datasources is to use the "iSeries Access ODBC Driver" name however, this is not required. The Client Access ODBC Driver name is still registered to allow applications that use existing datasources (DSNs) or DSN-less connections to run without requiring changes. There is no functional difference between them. Users of V5R2 iSeries Access for Windows may notice that the following ODBC driver names are registered:īoth names represent the same driver.
