Connecting a 32-bit Application to jBASE

jBASE provide an ODBC driver that enables third party applications to connect to a jBASE instance.

The ODBC driver's architecture is 64-bit, which means it can only be used with a 64-bit application. This is because an application and its libraries (e.g. the ODBC Driver and the ODBC Driver Manager the application uses to load the ODBC Driver) must all be the same architecture.

There is a solution, however. The Easysoft ODBC-ODBC Bridge enables a 32-bit application to connect to a 64-bit ODBC Driver (and vice versa). For example, you can use the ODBC-ODBC Bridge to connect the 32-bit application version of Microsoft Access to jBASE.

The ODBC-ODBC Bridge has two components: the Client and Server, which can be installed on either the same machine or on different machines. The ODBC-ODBC Bridge Client communicates with the ODBC-ODBC Bridge Server via RPC, which means the architecture of the Client does not dictate the architecture of the Server. So, a 32-bit Client is compatible with a 64-bit Server (and vice versa).

The ODBC-ODBC Bridge sits in between the application and ODBC driver. The Client passes the ODBC calls the application makes to the Server, which then passes them on to the application.

  1. If you have not already done so, in the 64-bit version of the ODBC Administrator, configure a jBASE ODBC data source on the machine where the jBASE ODBC driver is installed.

    To run the 64-bit ODBC Administrator, in the Windows Run dialog box, enter:

    odbcad32.exe
  2. Install the ODBC-ODBC Bridge Client on the machine where your application is installed.
  3. Install the ODBC-ODBC Bridge Server on the machine where the jBASE ODBC driver is installed.
  4. On the machine where your application is installed, use the 32-bit version of the ODBC Administrator to configure an ODBC-ODBC Bridge Client data source.

    To run the 32-bit ODBC Administrator, in the Windows Run dialog box, enter:

    %windir%\syswow64\odbcad32.exe
    Point the data source at the ODBC-ODBC Bridge Server that's installed on the jBASE ODBC connector machine, specify a Window user name and password for this machine. Specify your jBASE data source in the TargetDSN list.
  5. In your application, connect to your new ODBC-ODBC Bridge data source.
