Some client applications do not connect to Adaptive Server directly through the Open Client software, but through the ODBC (Open Database Connectivity) driver instead.
For example, both PowerDesigner™ and NetImpact Dynamo connect through the ODBC driver. Other third-party applications may also require the ODBC driver.
For Adaptive Server versions previous to 12.5, the ODBC connections are built on top of the Open Client Client-Library, so you need to install the Open Client software on the clients where you install the ODBC Driver.
The Adaptive Server installation program automatically installs the ODBC Driver on the computer on which you install NetImpact Dynamo.
You can also install the driver separately on other client workstations on which you will be running third-party or developed products.
For more information about the ODBC driver, see the ODBC Driver Reference Guide.
To use ODBC connections, you need to configure the Adaptive Server ODBC driver to allow connection to Adaptive Server.
