Oracle Notification Service (ONS) allows for Oracle RAC to communicate the status for the nodes, which are typically UP and DOWN events, to the Oracle JDBC driver and the driver's connection cache. To take advantage of ONS, you must configure the application server to use Oracle's connection caching instead of the application server's connection pooling feature.
ONS 服务将RAC节点的 启停信息 通知给JDBC connection cache, 使用该特性必须要 java程序中 使用了ONS对应的包 ons.jar (48,492 bytes) - for use by the pure Java client-side Oracle Notification Services (ONS) deamon.
国内几乎没有人会用ONS ,所以 无所谓 |
