4.5 Configuring Oracle Parameters

WebLogic Server provides several attributes that provide improved Data Source performance when using Oracle drivers, for more information, see Section 6, Advanced Configuration for Oracle Drivers.

4.6 Configuring an ONS Client

The following section provides information on how to configure an ONS client. ■ Section 4.6.1, Enabling FAN Events ■ Section 4.6.2, Configuring Generic Data Source Connection Testing. ■ Section 4.6.3, Using a Wallet File

4.6.1 Enabling FAN Events

Enabling a data source to subscribe to and process Oracle Fast Application Notification FAN events.

1. Select Fan Enabled

2. Provide a comma-separate list of ONS daemon listen addresses and ports for

receiving ONS-based FAN events. You can use Single Client Access Name SCAN addresses to access FAN notifications. See Configure ONS client parameters in Oracle WebLogic Server Administration Console Help.

4.6.2 Configuring Generic Data Source Connection Testing

Enabling FAN events automatically disables generic data source connection testing. However, if the ONS server is down or in unhealthy state, you can disable Fan Enabled and use generic data source connection testing to maintain the health state of database connections. For more information, see Section 10.2, Connection Testing Options for a Data Source.

4.6.3 Using a Wallet File

To communicate with ONS daemons using SSL, you must use a wallet file. See Section 4.2.5.1, Secure ONS Client Communication. .

4.7 Configuring Oracle Parameters

WebLogic Server provides several attributes that provide improved Data Source performance when using Oracle drivers, for more information, see Section 6, Advanced Configuration for Oracle Drivers.

4.8 Tuning GridLink Data Source Connection Pools

By properly configuring the connection pool attributes in JDBC data sources in your WebLogic Server domain, you can improve application and system performance.
