RAC db指定local_listener

异常：测试RAC DB装起来之后，port指定 1522，但 client连接时报错 No Listener

解决：

1)     在2个节点分别执行：

alter system set local_listener = '(ADDRESS =(PROTOCOL=TCP)(HOST=db303v)(PORT=1522))' sid ='trel2';

alter system set local_listener = '(ADDRESS =(PROTOCOL=TCP)(HOST=db103v)(PORT=1522))' sid ='trel1';

或 单独执行：alter system set local_listener = LISTENERS_TREL;

2)   重开 listener. 确认listener正常开启后, 测试连接instance
