  1. There are no DBMS requirements associated with the Enterprise Edition (Multi-Tier) Generic Client ODBC Drivers.
  2. The Enterprise Edition (Multi-Tier) Generic Client ODBC Drivers are distributed as Universal Binaries, automatically supporting all 32-bit and 64-bit clients, with both PowerPC- and Intel-based binaries.


  1. Download the OpenLink Generic ODBC Driver for macOS disk image (.dmg) file.
  2. Double-click the disk image file to open it.
  3. Run the installer .mpkg file located inside the disk image.


  1. To configure an ODBC DSN, perform the following steps:
    • Run the OpenLink iODBC Administrator located in the /Applications/iODBC folder.
    • Click the Add button on the System DSN tab.
    • Select the OpenLink Generic ODBC Driver from the list of available drivers.
    • Select the Unicode version of the driver if and only if you are working with multi-byte character sets, as unnecessary translations can significantly affect ODBC performance.
    • Provide a suitable DSN name and optional description for the Data Source.
    • Click the "Manual settings..." link in the Server field and specify the host name and port on which the OpenLink Request Broker listens. Click OK to exit the host and port dialog.
    • Click Continue to proceed.
  2. The Connection tab takes the minimum parameters required to make a connection to the target database:
    • Domain - The value must match a [Domain Alias], which is contained in the Server's Session Rules Book.
    • Name - May take several settings, depending on the Domain (e.g., database name, JDBC driver classname, Oracle SID, etc.).
    • Server - This field passes DBMS-specific connection parameters. Review Complete Settings and Usage for Connect Options
    • Review Complete Settings and Usage for Connect Options.
    • Click Continue to proceed.
  3. On the Connection tab, input the following:
    • Username - A valid database uid.
    • Password - A valid database password.
    • Click Continue.
  4. The Options tab contains settings that are not required for a basic connection:
    • Read Only connection - Specifies whether the connection is "Read-only." Make sure the checkbox is unchecked to request a "Read/Write" connection.
    • Defer fetching of long data - Defers fetching of LONG (BINARY, BLOB, etc.) data unless explicitly requested in a query.
    • Disable interactive login - Suppresses the ODBC "Username" and "Password" login dialog boxes when interacting with your ODBC DSN from within an ODBC compliant application.
    • Multiple Active Statements Emulation - Enables the use of Multiple Active statements in an ODBC application even if the underlying database does not allow this, as it is emulated in the driver.
    • Row Buffer Size - This attribute specifies the number of records to be transported over the network in a single network hop. Values can range from 1 to 99.
    • Click Continue.
  5. Click on the 'Test Data Source button to make a connection to the database and verify Client-to-Broker connectivity.
