If you want the latest JDBC driver to be picked up across all the domains in the server. To Apply the Changes Across All the Domains Either a Single Domain (or) across all domains. There are two options while updating the classpath, based on the scope of your change.

The First one is Replace the existing JDBC driver and the second one is updating the Classpath Step1: Replace the JDBC Driver
#Oracle jdbc jar file upgrade#
To upgrade the JDBC driver in weblogic you need to do two set of actions. Once you found the directory where the JDBC driver files are present now it is the time to replace the JAR files with your desired version.ĬAUTION: Having one or more version of same JAR file would create a Class Casting Exception so it is recommended to take a backup of the old JAR files some where and REPLACE with the new JAR file.įor this post, we are taking mysql as our Database but you can refer this for Oracle Database as well. The listing for oracle_common directory would look like this. Having said that, MW_HOME and ORACLE_HOME are the same in my case.

To know more about all these HOME directories and how to find them and differentiate them easily. Refer the following post for more information on these homes. In fact, there is another exclusive variable like ORACLE_COMMON_HOME to avoid confusion. I can refer to my MW_HOME here to get to oracle common directory The ORACLE_HOME and MW_HOME would mostly be the same. In such cases there would be various ORACLE_HOMES might be present like $MW_HOME/weblogic12c, $MW_HOME/OracleHTTPServerīut, When it comes to only Weblogic installation and not full FMW setup. In a fully featured Fusion Middleware installation setup, There would be many Oracle products installed under the same MW_HOME. In my case: The ORACLE HOME is / apps/oracle-weblogic/wls12213 which is apparently my MW_HOME as well.
#Oracle jdbc jar file drivers#
Weblogic 12c directory structure is slightly different than the weblogic 11gįor weblogic 12c, The JDBC drivers (jar files) can be found in $ORACLE_HOME/oracle_common/modules Photo by Jungwoo Hong on Unsplash Weblogic 12c So we have given separate instructions for both versions, to keep things isolated and for better understanding. Though the Process is more similar for both Weblogic11g and 12c there is few minor differences like the PATH and the FILE. Let us find where weblogic keeps these JDBC related drivers by default and learn how to upgrade them for both versions ( Weblogic 11g and 12c) But it would mostly be accompanied by the Database product (or) version upgrade. Some companies and infrastructures choose to change their JDBC version for performance reasons as well. In general, Weblogic comes with these driver jar files, but they often get outdated when their time comes. The JDBC driver names would vary or change based upon the Database product we are usingįor Oracle Database the JDBC driver name would be ojdbc6.jar (or) ojdbc7.jar wherein the case of MySQL the file name would be something like mysql-connector-.jar so does for Oracle and other Relational Database management Systems. The answer is JDBC and Application servers use various JDBC drivers to connect to different databases.įor Weblogic to connect to the MySQL, Weblogic must be having the MySQL JDBC driver. If you are here, I can presume that you must be aware of how application servers communicate to the Database. Steps to Upgrade JDBC driver in Weblogic.
