Before you begin
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.
Prior to creating a JDBC system resource override, you must have previously created a JDBC data source. See Create JDBC generic data sources.
Resource overriding allows administrators to customize resources at the partition level. 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. On this overriding configuration MBean there is a name for the override MBean itself and there is a data source name attribute. 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.
The Domain Partitions table displays all the partitions defined in the domain.
The JDBC System Resource Overrides table dislays all the JDBC system resource overrides that have been configured in this domain partition.
The overriding configuration MBean's data source name does not override the data source name of the resource. It is used for matching the overriding configuration MBean with the resource to be overridden.
The new JDBC system resource override appears in the resource overrides table.
After you finish
If the resource is running, you must restart the partition for the overrides to take effect.
