Configuring and Managing WebLogic JDBC
jConnect.jar) and 5.5 (
These drivers are installed in the WL_HOME
\server\lib folder (where WL_HOME is the folder where WebLogic Server is installed) with
weblogic.jar. The manifest in
weblogic.jar lists these files so that they are loaded when
weblogic.jar is loaded (when the server starts). Therefore, you do not need to add these JDBC drivers to your
CLASSPATH. If you plan to use a third-party JDBC driver that is not installed with WebLogic Server, you must install the drivers, which includes updating your
CLASSPATH with the path to the driver files, and may include updating your
PATH with the path to database client files. See "Supported Database Configurations in Supported Configurations for WebLogic Server 9.0.
Note: The WebLogic Type 4 JDBC drivers from DataDirect are also installed with WebLogic Server. See WebLogic Type 4 JDBC Drivers for more information.
If you plan to use a different version any of the drivers installed with WebLogic Server, you can replace the driver file in
\server\lib with an updated version of the file or add the new file to the front of your
Copies of the drivers installed with WebLogic Server and other supporting files are installed in WL_HOME
\server\ext\jdbc\. There is a subdirectory in this folder for each DBMS. If you need to revert to the version of the driver installed with WebLogic Server, you can copy the file from WL_HOME
Note: WebLogic Server also includes the PointBase 5.1 JDBC driver and an evaluation version of the PointBase DBMS installed with the WebLogic Server examples in
\common\eval\pointbase. PointBase Server is an all-Java DBMS product included in the WebLogic Server distribution solely in support of WebLogic Server evaluation, either in the form of custom trial applications or through packaged sample applications provided with WebLogic Server. Non-evaluation development or production use of the PointBase Server requires a separate license be obtained by the end user directly from PointBase.
If you plan to use a third-party JDBC driver that is not installed with WebLogic Server, you need to update the WebLogic Server's classpath to include the location of the JDBC driver classes. Edit the
commEnv.cmd/sh script in
/common/bin and prepend your classes as described in "Modifying the Classpath" in WebLogic Server Command Reference.
For Globalization Support with the 10g version of the Oracle Thin driver, Oracle supplies the
orai18n.jar file, which replaces
nls_charset.zip. If you use character sets other than US7ASCII, WE8DEC, WE8ISO8859P1 and UTF8 with CHAR and NCHAR data in Oracle object types and collections, you must include
orai18n.jar in your
orai18n.jar is included with the WebLogic Server installation in the
\server\ext\jdbc\oracle\10g folder. The file is not referenced by the weblogic.jar manifest file, so you must add it to your
CLASSPATH before you can use it.
\server\ext\jdbc\oracle\10g folder includes the
ojdbc14_g.jar file, which is the version of the Oracle Thin driver with classes to support debugging and tracing. To use the Oracle Thin driver in debug mode, add the path to this file at the beginning of your
