How To Install and Configure the Lite Edition ODBC-to-JDBC Bridge Drivers (Windows)

Pre-Installation Guide

  1. You must have a Java Runtime Environment (JRE) that is compatible with the Single-Tier (Lite Edition) ODBC Driver for JDBC Data Sources.
    • Generally, the latest JVM from is the best choice.
    • If using a 64-bit ODBC Driver, you must have a 64-bit JVM.
  2. You must possess third-party or native JDBC drivers that connect to your target database.
  3. If your 3rd party JDBC Driver connection attempt isn't successful, check that the JDBC driver jar file (or a symbolic link to it) is included in the active $CLASSPATH.
  4. Note: Supporting Java libraries (or links to them) may also need to be referenced by this variable value.
  5. Finally, directories containing other supporting libraries may need to be referenced by other shared library environment variables (e.g., LD_LIBRARY_PATH, LIBPATH, SHLIB_PATH).

Installation Guide

  1. Download and open the Lite Edition (Single-Tier) ODBC Driver for JDBC Data Sources (also known as the ODBC-to-JDBC Bridge) is distributed in a single .msi file.
    • Download and double click on the downloaded .msi.
  2. Your driver needs a license file to operate.
    • Click the Browse button to locate a commercial or evaluation license that you have previously downloaded onto your local hard drive.
    • Alternatively, click the Try & Buy button to obtain a commercial or evaluation license.
    • 64-Bit licenses are installed in C:\Program Files\OpenLink Software\UDA\bin\.
    • 32-Bit licenses are installed in C:\Program Files (x86)\OpenLink Software\UDA\bin\.
  3. Proceed to configuring an ODBC Data Source Name (DSN) that binds to your target JDBC database.

Configuration Guide

  1. Determine that you have a working JDBC connection to your target database.
  2. Also determine the bitness (32-bit or 64-bit) of the driver used as this MUST match the Java Virtual Machine and ODBC-JDBC Bridge Driver bitness.
  3. Launch the ODBC Data Sources Application and click the System DSN tab.
  4. Click the Add button.
  5. Select the OpenLink "Lite" Driver for JDBC Data Sources from the list of available drivers.
  6. 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.
  7. Click Finish.
  8. The first dialog prompts for a Data Source Name and optional description. Click Next.
  9. The second dialog prompts for a third-party JDBC driver name, JDBC connection URL, and authentication parameters associated with that JDBC URL.
    • JDBC driver: This is the class name of the target JDBC driver.
    • URL string: This is the JDBC connection URL for the target JDBC driver.
    • Connect now to verify that all settings are correct: Will attempt to connect to the database, once you click Continue.
    • Login ID: This is a valid username for your JDBC database.
    • Password: This is a valid password for your JDBC database.
  10. Click Next to continue.
  11. The third dialog takes a combination of database-specific and optional parameters.
    • Drop Catalog name from DatabaseMetaData calls: Enable this option to have the catalog name not appear for tables, views, and procedures when requesting database meta-data.
    • Drop Schema name from DatabaseMetaData calls: Enable this option to have the schema name not appear for tables, views, and procedures when requesting database meta-data.
    • Return an empty ResultSet for SQLStatistics: Check this box to have SQLStatistics() return an empty resultset. Use this if the underlying database does not support retrieval of statistics about a table (e.g., what indexes it has).
    • Disable support of quoted identifier: If set, the call SQLGetInfo(SQL_IDENTIFIER_QUOTE_CHAR) will return a space (""). It can be used if the DBMS doesn't support quoted SQL like SELECT * FROM "account".
    • Disable support of search pattern escape: If set, the call SQLGetInfo(SQL_LIKE_ESCAPE_CLAUSE) will return a space (""). It can be used if the DBMS doesn't support SQL escape patterns.
    • Enable logging of JDBC calls to the log file: Check this option to enable logging of JDBC calls to a log file.
  12. Click Next to continue.
  13. The fourth dialog enables you to set optional ODBC connection parameters.
    • Read-only connection: Specifies whether the connection is "Read-only." Must be unchecked to INSERT, UPDATE, or DELETE records and to run some Stored Procedures, including some built-in functions.
    • Defer fetching of long data: Defers fetching of LONG (BINARY, BLOB, etc.) fields in wildcard queries. This provides significant performance increases when fields in the query do not include LONG data fields.
    • Disable interactive login: Suppresses the ODBC "Username" and "Password" login dialog boxes when interacting with your ODBC DSN from within an ODBC-compliant application.
    • Row Buffer Size: This attribute specifies the number of records to be delivered from the driver to the client application in a single batch. Values can range from 1 to 999.
    • Max Rows Override: Allows you to set a limit for the maximum number of rows to be returned from a query. The default value of 0 means no limit.
    • Initial SQL: Lets you specify a file containing SQL statements that will be run automatically against the database upon connection.
    • Dynamic Cursor Sensitivity: Enables or disables the row version cache used with dynamic cursors.
    • Enable logging to the log file: Check the checkbox and use the associated textbox to provide the full path to a file in which to log diagnostic information.
  14. Click Next to continue.
  15. The fifth dialog enables you to set additional parameters to enhance compatibility with applications.
    • Enable Microsoft Jet engine options: Facilitates translation of certain data types for the Microsoft Jet Engine. If you notice that money and other datatypes are mishandled with Microsoft or other applications, test with Jet fix enabled.
    • Disable Autocommit: Changes the commit behavior of the OpenLink driver. The default mode is AutoCommit (box unchecked).
    • Disable rowset size limit: Disables a limitation enforced by the cursor library. This limitation is enforced by default. It prevents the driver from claiming all available memory when a resultset (typically generated by an accidental query) is very large. The limit is not normally reached.
    • Multiple Active Statements Emulation: Enables the use of Multiple Active statements in an ODBC application even if the underlying database does not allow this by emulation within the driver.
    • SQL_DBMS Name: Manually overrides the SQLGetInfo(SQL_DBMS_NAME) response returned by the driver. This is required for products like Microsoft InfoPath for which the value should be "SQL Server".
  16. Click Next to continue.
  17. The final dialog enables you to test your Data Source. Click the Test Data Source button.
