环境:RHEL5 64bit+ORACLE10.2.0.4 RAC,进行数据迁移,迁移成功后进行连接测试,报告:TNS-01184: Listener rejected registration or update of service handler "DEDICATED" 错误;进行排查,tnsping各个节点实例及服务名均没有问题,怀疑是否防火墙没有打开5000之上的端口,造成连接请求时,服务器无法返回连接端口,通过测试并询问网络工程师,证明端口都正常开启,非常奇怪,后查看监听配置信息发现,监听配置重叠,造成远端监听无法解析,修改后测试一切正常,修改后监听信息:
节点1:

节点2:

由于是数据迁移,在迁移之前,添加时在一个节点上运行的脚本,并没有确定实例名,而用SCOPE=BOTH,所以造成重叠,查看日志如下:
节点1: ALTER SYSTEM SET local_listener='(DESCRIPTION_LIST=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=bj-mini-xhm-3f2-dl580-db1-vip)(PORT=152 2))(ADDRESS=(PROTOCOL=TCP)(HOST=10.142.145.7)(PORT=1522))))' SCOPE=BOTH; Tue Jul 26 15:16:25 2011 ALTER SYSTEM SET remote_listener='(DESCRIPTION_LIST=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=bj-mini-xhm-3f2-dl580-db2-vip)(PORT=15 22))(ADDRESS=(PROTOCOL=TCP)(HOST=10.142.145.8)(PORT=1522))))' SCOPE=BOTH;
节点2: ALTER SYSTEM SET local_listener='(DESCRIPTION_LIST=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=bj-mini-xhm-3f2-dl580-db2-vip)(PORT=152 2))(ADDRESS=(PROTOCOL=TCP)(HOST=10.142.145.8)(PORT=1522))))' SCOPE=BOTH; Tue Jul 26 15:27:35 2011 ALTER SYSTEM SET remote_listener='(DESCRIPTION_LIST=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=bj-mini-xhm-3f2-dl580-db1-vip)(PORT=15 22))(ADDRESS=(PROTOCOL=TCP)(HOST=10.142.145.7)(PORT=1522))))' SCOPE=BOTH;
分别在各自的节点运行,之后正常: 在节点1运行如下:
ALTER SYSTEM SET local_listener='(DESCRIPTION_LIST=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=bj-mini-xhm-3f2-dl580-db1-vip)(PORT=1522))(ADDRESS=(PROTOCOL=TCP)(HOST=10.142.145.7)(PORT=1522))))' SCOPE=BOTH SID=cdb1; ALTER SYSTEM SET remote_listener='(DESCRIPTION_LIST=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=bj-mini-xhm-3f2-dl580-db2-vip)(PORT=1522))(ADDRESS=(PROTOCOL=TCP)(HOST=10.142.145.8)(PORT=1522))))' SCOPE=BOTH SID=cdb1;
在节点2运行如下:
ALTER SYSTEM SET local_listener='(DESCRIPTION_LIST=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=bj-mini-xhm-3f2-dl580-db2-vip)(PORT=152 2))(ADDRESS=(PROTOCOL=TCP)(HOST=10.142.145.8)(PORT=1522))))' SCOPE=BOTH SID='cdb2'; Fri Aug 12 00:48:26 2011 ALTER SYSTEM SET remote_listener='(DESCRIPTION_LIST=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=bj-mini-xhm-3f2-dl580-db1-vip)(PORT=15 22))(ADDRESS=(PROTOCOL=TCP)(HOST=10.142.145.7)(PORT=1522))))' SCOPE=BOTH SID='cdb2';
计划9:30搞定的东东,居然弄到凌晨2点,不得不说,一切皆有可能呀。 |
