How To Install and Configure the Multi-Tier Edition JDBC Drivers for MySQL (Windows)

Server Components

Installation (Request Broker and Database Agent)

  1. Our Enterprise Edition (Multi-Tier) server components installers for Windows are distributed as .msi files. You need to download one Enterprise Edition Request Broker installer (ntbrzzzz.msi for all 32-bit processor architectures, wabrzzzz.msi for x86_64, or wibrzzzz.msi for IA_64) and at least one Agent installer (same architecture) for the specific target data source(s). Double-click on the downloaded request broker .MSI file to start the installation.
  2. The Request Broker installers will specifically prompt for the location of a local license file.

    Note: Agent installers do not, as their licensing is handled through the Broker.
  3. Click the "Browse" button to locate a license file on your Windows machine.
  4. Check the "I don't want to install a license file" box if you do not have one.
  5. Once Completed, run the Database agent installation by clicking on the downloaded .MSI file.
  6. The Request Broker can be started and stopped by locating the OpenLink Request Broker service in the Services panel, or by using the toolbar service shortcut provided after installation.
  7. Installation is complete, proceed to making a test connection with your Client Component installation. If you haven't installed this component, please follow one of the following
Non-Advanced Users should proceed to the Client Components installation and configuration guides
  1. Open the "ODBC Data Sources" Application.
  2. 64-bit drivers should be configured with the 64-bit Application.
  3. 32-bit drivers should be configured with the 32-bit Application.
  4. Select the System DSN tab, then click Add.
  5. Select the OpenLink "Lite" Driver for MySQL Data Sources 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.
  6. Click Finish.
  7. The first dialog prompts for a Data Source Name and optional description.
  8. Click Next.
  9. The second dialog prompts for information that identifies the MySQL database server and listen port. It also provides a checkbox that allows you to check your basic connection parameters before setting advanced and optional settings:
    • Host - The hostname or IP address of the server on which MySQL runs
    • Port - The TCP port on which MySQL listens
    • Database - The MySQL database
    • Login ID - A MySQL username
    • Connect now to verify that all settings are correct - Will attempt to connect to the database, once you click Continue.
    • Password - A valid MySQL database password
  10. Click Next.
  11. The third dialog enables you to set MySQL specific parameters:
    • No transactions - Disable ODBC transaction management. All transactions will be automatically committed. This prevents palloc() failures with out-of-memory errors when doing really big transactions, such as exporting 10,000 records from Microsoft Access.
    • Catalogs return Owner - Check this box so that ODBC API catalog calls return values in catalog columns as the database owner or schema.
    • Use Cursor Fetch - This parameter, specific to MySQL 5, enables the use of internal cursors to fetch result sets.
    • Prepare Method - Enables you to specify the Prepare/Execute Method. More
    • Character set - Allows you to choose the client character set. (ANSI only)
  12. Click Next.
  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 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.
  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 is very large.
    • Multiple Active Statements Emulation — Enables 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.
  16. Click Next.
  17. The final dialog enables you to test your Data Source. Click the Test Data Source button.
  18. Once a successful connection has been established, click Finish.

Client Components

  1. The OpenLink installer should set your CLASSPATH. You should have a pre-existing JAVA_HOME directory that points to the root of your Java installation; this same directory should also be included in your PATH. No further configuration should be needed.
  2. Driver Name: opljdbc.jar, opljdbc2.jar, opljdbc3.jar, megathin.jar, megathin2.jar, megathin3.jar
    Driver Class Name: openlink.jdbc.Driver, openlink.jdbc2.Driver, openlink.jdbc3.Driver
    Connection URL:
    jdbc:openlink://<Hostname>:[portnumber] [/UID] [/PWD] [/READONLY] [/SVT]

    • Hostname - DNS-resolvable hostname or IP address of the machine that runs an OpenLink Request Broker instance.
    • Port Number - TCP port on which the Request Broker listens.
    • /UID - Database username.
    • /PWD - Database password.
    • /READONLY - Read-write or read-only session mode.
    • /SVT - A valid domain alias from the [Domain Aliases] section of the OpenLink server component's oplrqb.ini file. Default domain aliases represent the type of database agent to which the application intends to connect, e.g., DB2, Informix 2000, Oracle 8.1.x. Custom aliases may be any string.
    • /APPLICATION - The Application name. Enables connectivity when restrictive server-side rules screen by application name.
    • /FBS - (also /FETCHBUFFERSIZE) The number of rows to return during one fetch operation.
    • /ENCRYPTED - Encrypt outgoing OpenLink communications packets. Disabled by default. Enabled with '1', 'Y', 'y'; disabled with '0', 'N', 'n'.
    • /CHARSET - The charset of remote databases. The default value is read from System.getProperty("file.encoding").
    • /UNICODE - Enables a Unicode connection. Disabled by default. Enabled with '1', 'Y', 'y'; disabled with '0', 'N', 'n'.
    • /DLF - Defers large data fields (BLOB, CLOB, etc.) to the end of the resultset. Smaller data types are retrieved first. This enhances performance. Disabled by default. Enabled with '1', 'Y', 'y'; disabled with '0', 'N', 'n'.
    • /DATABASE - Actual database name within a particular database environment.
    • /OPTIONS - Optional connection attribute passes specialized database-native client connection parameters, such as Progress socket parameters, Oracle SQL*Net Service Names, Ingres vnodes, remote Informix instance names, or DB2 remote database aliases. Not necessary when ConnectOptions are set in the Broker Rulebook.
    • /DRIVER - An ODBC Driver name wrapped in braces ("{}"). Used for DSN-Less connections to remote ODBC Drivers.
