ORACLE RAC中连接ScanIP报错ORA

才安装好的一个ORACLE 11G 11.2.0.4的一套RAC，通过DG同步的数据，激活用于测试，在本地通过SCANIP链接，没有问题，conn sz/sz2486@192.168.133.2:1521/orcl

Connected.

但从其他机器链接，就会报错：

SQL> conn sz/sz2486@192.168.133.2:1521/orclERROR:ORA-12545: Connect failed because target host or object does not exist

这里的原因是节点的LOCAL_LISTENER参数设置为了空.在RAC中,每个节点的LOCAL_LISTENER参数必须指定本节点的vip,remote_listener必须指向scanIP.

检查一下服务器端的设置：

SQL> show parameter list

NAME TYPE VALUE

------------------------------------ -----------

------------------------------

listener_networks string

local_listener string

remote_listener string db-scan:1521

马上设置LOCAL_LISTENER

SQL> alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.133.9)(PORT=1521))' sid='orcl1';SQL> alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.133.10)(PORT=1521))' sid='orcl2';

再去测试，问题解决conn sz/sz2486@192.168.133.2:1521/orcl

Connected.
