ORACLE RAC中连接ScanIP报错ORA-12545的问题解决
2022-06-11 09:17:00 【cqszpx】
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/[email protected]:1521/orcl
Connected.
但从其他机器链接,就会报错:
SQL> conn sz/[email protected]:1521/orcl
ERROR:
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/[email protected]:1521/orcl
Connected.
附ORACLE MOS上文档:ORA-12545 or ORA-12537 While Connecting to RAC Through SCAN name (Doc ID 970619.1)
