> This page summarizes the JDBC system resource overrides that have been configured in this domain partition.

> NOTE: WebLogic Server Multitenant domain partitions are deprecated in WebLogic Server 12.2.1.4.0. The related Console and help pages will be removed in the next release.

> A JDBC system resource override defines a partition-specific JDBC data source attribute override of a data source descriptor referenced by a partition resource group definition. The system matches overrides with JDBC system resources by comparing the data source name attribute from the overriding configuration MBean with the name in the JDBCDataSourceBean that is pointed to by the JDBCSystemResourceMBean.
