JDBC Data Sources

A JDBC data source contains a pool of database connections that are created when the data source instance is created—when it is deployed or targeted, or at server startup. Applications look up a data source on the JNDI tree, and then request a connection. When the applications no longer need the connections, they return the connections to the connection pool in the data source.

Use this screen to configure the JDBC data sources defined in your domain source.

The JDBC data sources associated with the products for which you are creating the domain are listed in the lower half of the screen.

Select the data source(s) for which you want to specify settings by selecting the check box adjacent to each data source name. The values that you specify are displayed in the appropriate columns in the data source list, for the selected data source.

Notes:

When you select multiple data sources, the text "Varies among component schemas" might be displayed in certain fields, indicating that the current values of those fields are different across the selected data sources. If you change the values in such fields, the new values are applied uniformly across the selected data sources.

The default values of data source parameters such as vendor, driver, host name, and port number depend on the values that are specified in the application templates.

Field	Description
Vendor	Select the database vendor.
Driver	Select the JDBC driver to use to connect to the database. The list includes common JDBC drivers for the selected database vendor.
DBMS/Service	Enter a DBMS SID or service name. The value that you enter depends on the driver that you selected. If the name of the Oracle driver that you selected contains the words "for Instance connections," you must enter the SID. If the name of the Oracle driver contains the words "for Service connections," you must enter the service name. For information about configuring a DataDirect driver, see the DataDirect documentation.
Host Name	Enter the name of the server hosting the database.
Port Name	Enter the port number to be used to connect to the server.
Username	Enter the username for connecting to the database.
Password	Enter the password for the specified username.

To convert one or more data sources to GridLink RAC data sources, select the check boxes adjacent to the name of the those data sources, and select the Convert to GridLink option. Click Next when done. When you click Next, the GridLink Oracle RAC Data Sources screen is displayed. More

To convert one or more of the data sources to Oracle RAC multi data sources, select the check box adjacent to the name of the required data source, and select the Convert to RAC multi data source option. When you click Next, the Oracle RAC Multi Data Sources screen is displayed. More
