1. Check the status of listener $ lsnrctl status 2. If the listener isn't be started, start it $ lsnrctl start 3. Set the "ORACLE_SID" environment to the DB instance's SID which you want to start, for example $ export ORACLE_SID=PC855 4. Start sqlplus and start the DB instance ...
这个进程中,发现实例已崩溃,并且将请求转移到其他实例上,就属于是listener的功能。 5、 负载均衡衡量。在RAC架构中,Oracle实现了负载均衡。当一个客户请求到来时,Oracle会根据当前RAC集群环境中所有实例的负载情况,避开负载较高的实例,将请求转移到负载较低的实例停止处置。在初期RAC版本中,负载轻重的衡量是根据监听器...

This demo shows how to configure Oracle WebLogic Server to work with Oracle Real Application Clusters (RAC) as well as how to test the connections to the backend Oracle RAC nodes using a web application.Oracle WebLogic Server 10.3 integrates Oracle Real Application Clusters (RAC) features in ...
Along with these great features, there are also simple benefits. When pool.getConnection() is called in node-oracledb, the pool checks that the network socket of the connection about to be returned to the application hasn't been killed. If it has been destroyed, then the pool cleans up, ...
jdbc:oracle:thin:@{scan-listener-host}:{scan-listener-port}/{service-name} Example: jdbc:oracle:thin:@apctcsol1.au.oracle.com:1521/pas_srv One way to determine the SCAN host/port is by connecting to any of the RAC instances in the cluster as shown below. ...
