oracle 11g RAC 更改remote_listener参数后EM日志报错：ORA-12514, TNS:listener does not currently know of service


环境：oracle 11g + RAC + ASM + raw + 2node + redhat5.7

[root@rac01 ~]# cat /etc/hosts

# add by RAC install

# public  eth1

192.168.1.5    rac01

192.168.1.6    rac02

# vip    eth1:1

192.168.1.222    rac01-vip

192.168.1.223    rac02-vip

# private  eth0

10.10.11.26   rac01-priv

10.10.11.46   rac02-priv

# single client access name  (scan)

192.168.1.225   rac-scan

本人配置 服务端 基于vip的负载均衡，更改remote_listener参数后，EM登入后总是说实例未启动，要求启动

但是实际数据库实例是已经启动的，查看EM日志如下：

2015-01-22 04:57:29,565 [shutdownThread] ERROR app.SessionObjectManager sessionDestroyed.128 -

java.sql.SQLException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

The Connection descriptor used by the client was:

rac-scan:1521/racdb

其实就是oracle用户更改了remote_listener参数导致数据库不再可以通过scan ip登入数据库了，实则就是没有监听它了

先前 remote_listener 参数值为  rac-scan:1521

改为了用于负载均衡的值   LISTENER_RACDB                        ---负载均衡及其他功能均正常

而EM中配置的连接节点二的描述还是写的先前的 rac-scan:1521 固然连接不上了

解决办法：

1.先停止两个节点的EM：

[oracle@rac01 ~]$ emctl stop dbconsole

[oracle@rac02 ~]$ emctl stop dbconsole

2.直接修改EM的配置文件：(将rac-scan改为任意vip地址)

/u01/app/oracle/product/11.2.0.3/db_1/rac01_racdb/sysman/config/emoms.properties

/u01/app/oracle/product/11.2.0.3/db_1/rac01_racdb/sysman/emd/targets.xml     （这个文件先不修改，如果进入EM跳转连接还是会转回登入页面再修改）

3.修改listener.ora和tnsnames.ora

[grid@rac01 ~]$ cat /u01/11.2.0.3/grid/network/admin/listener.ora                                    ---   rac02也同样修改（RAC各个节点的listener.ora文件配置一致）

[oracle@rac01 log]$ cat /u01/app/oracle/product/11.2.0.3/db_1/network/admin/tnsnames.ora                                             ---   rac02也同样修改

ps：标红处是添加的。

4.节点二也同样修改即可。

5.清空下EM的日志和缓存，重启下实例即可

[oracle@rac01 log]$ pwd

/u01/app/oracle/product/11.2.0.3/db_1/rac01_racdb/sysman/log

[oracle@rac01 log]$ rm -rf *

重启实例：

[grid@rac01 ~]$ srvctl stop listener

[grid@rac01 ~]$ srvctl stop scan_listener

[grid@rac01 ~]$ srvctl start listener

[grid@rac01 ~]$ srvctl start scan_listener

6.然后再在两个节点打开EM就可以正常访问了。

[oracle@rac01 ~]$ emctl start dbconsole

[oracle@rac02 ~]$ emctl start dbconsole

ps：如果登入后点击链接还是会回到登入界面（连接字符xxxxxx）

两个节点关闭EM，root用户重启下全部资源，再清空下EM缓存，再启动EM即可。

[oracle@rac01 ~]$ emctl stop dbconsole

[oracle@rac02 ~]$ emctl stop dbconsole

[root@rac01 ~]# /u01/11.2.0.3/grid/bin/crsctl stop cluster -all

[root@rac01 ~]# /u01/11.2.0.3/grid/bin/crsctl start cluster -all

[oracle@rac01 log]$ pwd

/u01/app/oracle/product/11.2.0.3/db_1/rac01_racdb/sysman/log

[oracle@rac01 log]$ rm -rf *

[oracle@rac01 ~]$ emctl start dbconsole

[oracle@rac02 ~]$ emctl start dbconsole
