GridLink Oracle RAC Component Schema

Use this screen to configure the component schemas that are included in your WebLogic domain as GridLink RAC data sources. A GridLink data source is a single data source that represents a service that responds to Fast Application Notification (FAN) events. More

The component schemas that you opted to configure as GridLink RAC data sources in the JDBC Component Schema screen of the wizard are listed in the lower half of the screen.

If you selected the Use RCU Parameters option on the Database Configuration Type screen, the schema table has already been populated appropriately and you can click Next to continue.
If you selected the Configure Manually option on the Database Configuration Type screen, you must configure the schemas listed in this table manually before continuing.

In the schema list in the lower half of the screen, select the schemas to configure as GridLink RAC data sources by selecting the check box adjacent to each schema name.

Note:

When you select multiple data source schemas, 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 schemas. If you go ahead and change the values in such fields, the new values are applied uniformly across the selected schemas.

Field	Description
Driver	Select the appropriate driver. Some or all of the following drivers are listed: Oracle Driver (Thin) for GridLink Connections This is the GridLink Type 4 non-XA driver. Oracle Driver (Thin XA) for GridLink Connections This is the GridLink Type 4 XA driver.
Service Name	Enter a database Oracle RAC service name.
Schema Owner	Enter the username for connecting to the database.
Schema Password	Enter the password for this username.
Enable FAN	When selected, the data source will register for and process FAN notifications.
Enable SSL	When selected, SSL is enabled, and you must specify a wallet file, wallet password, and at least one Oracle Notification Service (ONS) host/port.
Wallet File	If SSL is enabled, specify the full path to the wallet file that contains the credentials for ONS/SSL. A wallet file is an Oracle credential file that stores keys and certificates.
Wallet Password	Specify the password for the wallet file. The password will be encrypted in the module configuration file.
Service Listener	Enter the name of the GridLink database Service Listener. You must configure the Service Listener for at least one database instance.
Port	This is the listen port for the database service listener. It defaults to 1521 and typically does not need to be changed.
Protocol	Click in this field and select the protocol to use for communication between WebLogic Server and the database service listener.
ONS Host	Specify the Oracle Notification Service (ONS) host name. If SSL is enabled, you must specify at least one ONS host and port.
Port	Specify the listen port to use on the ONS host.

The values that you specify are displayed in the appropriate columns in the schema list, for the selected schemas.

To add another row to the Service Listener table, click anywhere in the table, and then click Add.

To add another row to the ONS Host table, click anywhere in the table, and then click Add.

To delete a row from the Service Listener table, click anywhere in the row, and then click Delete.

To delete a row from the ONS Host table, click anywhere in the row, and then click Delete.
