ORA-12514: TNS

fengyunsen

环境：
主库 ：rac2(192.168.0.162)
备库：memberstor-host(192.168.0.182)
两个库已经在broker下建立了dataguard,而且一切正常当中
但是当我尝试用rac2
操作：
dgmgrl>connect sys/******@192.168.0.182
时,就出现了：
Unable to connect to database
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor


listener.log07-FEB-2012 15:53:14 * (CONNECT_DATA=(SERVICE_NAME=192.168.0.182)(CID=(PROGRAM=dgmgrl@rac2)(HOST=rac2)(USER=oracle))) * (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.0.182)(PORT=18267)) * establish * 192.168.0.182 * 12514
TNS-12514: TNS:listener does not currently know of service requested in connect descriptor



监听端口都是默认的1521

connect sys/******@192.168.0.182

easy connection 的连接串形式  ip:port/Servicename

监听日志
listener.log07-FEB-2012 15:53:14 * (CONNECT_DATA=(SERVICE_NAME=192.168.0.182)(CID=(PROGRAM=dgmgrl@rac2)(HOST=rac2)(USER=oracle))) * (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.0.182)(PORT=18267)) * establish * 192.168.0.182 * 12514


SERVICE_NAME=192.168.0.182  ， 这里因为你的连接串写的 有问题所以把 ip当成servicename处理了， 肯定会出现ORA-12514错误

若要使用easy connection， 修改连接字符串

谢谢ML。由于不是很了解，老是遇到些问题，看来还是要沉淀一下，再多了解dataguard内在的东西
