Goal

How To Update the JDBC and UCP Drivers Bundled with WebLogic Server

This document describes how customers should upgrade the Oracle JDBC and UCP drivers bundled with WebLogic Server 10.3.6 and newer releases for support with certified Oracle Database versions.

Important:

This is not a document to instruct what Oracle Database versions are certified with different drivers. Information in this document will help one update and maintain the installed JDBC driver to improve functionality and fix issues connecting to any certified Oracle Database. To see what Oracle Database versions are certified with Oracle WebLogic Server, see the version's Certification at https://www.oracle.com/technetwork/middleware/ias/downloads/fusion-certification-100350.html or on My Oracle Support, Certifications tab.
Note that certifications are performed using the FMW/WLS installed JDBC driver, not replacing the driver with a different driver supplied by the Oracle Database Client because of a newer Database version. For 10.3.6, some fixes are required with an extra patch built just for WLS, and in 12c versions, there are patches applied to the JDBC component at installation time, along with other recommendations. --> Providing this information and maintenance thereof is the scope of this document.
Instead of using the WLS installed JDBC thin driver, one may update the CLASSPATH to pick up JDBC driver files of choice when using custom applications, (e.g., not FMW deployed applications). For WLS 10.3.6 and DB 12c releases, see <Note:1564509.1> . For early WLS 12c versions and DB 12.2, see https://blogs.oracle.com/weblogicserver/post/oracle-database-122-feature-support-with-weblogic-server. For 12.2.1.4 and 14.1.1, see https://docs.oracle.com/en/middleware/fusion-middleware/weblogic-server/12.2.1.4/jdbca/configure-database-connectivity.html#GUID-2DA777A9-FB2E-41A2-A2FD-06CE66C7DB11 . This allows an administrator to use a separate driver for testing or custom use cases where a fix or enhancement may not yet be available in the FMW/WLS installed drivers.
