Create JDBC system resource overrides

Before you begin

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.

To create a JDBC system resource override:

  1. In the left pane of the Console, select Domain Partitions.

    The Domain Partitions table displays all the partitions defined in the domain.

  2. Click on the name of the domain partition for which you want to create a JDBC system resource override.
  3. Select the Resource Overrides > JDBC System configuration page.

    The JDBC System Resource Overrides table dislays all the JDBC system resource overrides that have been configured in this domain partition.

  4. Click New.
  5. On the Create a New JDBC System Resource Override page, provide a Name for the JDBC system resource override.
  6. From the Data Source drop-down menu, select the name of the data source you want to override.

    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.

  7. Optionally, in the URL, User Name, and Password fields, provide partition-specific values and click OK.

    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.
