Oracle10g异机恢复后EM无法启动故障处理一例

遇到各种原因造成的EM无法登陆的问题，通常是因为旧的EM资料库配置有问题，或者是因为改变了主机或IP地址所造成，可以使用emca -

之前在自己的测试环境上做了个异机恢复，原来的库上是配置过EM的，但是在恢复的库上去启动EM就报错了，下面看具体解决过程：

PS：原主机名为zlm，恢复出来的主机名为bak

[root@bak ~]# su - Oracle

[oracle@bak ~]$ emctl status dbconsole

TZ set to PRC

OC4J Configuration issue. /u01/app/oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole_bak_ora10g not found.

既然提示文件找不到，很显然是因为主机名变更的缘故，那么把名字变一下，用mv命令

[oracle@bak j2ee]$ mv -r OC4J_DBConsole_zlm_ora10g/ OC4J_DBConsole_bak_ora10g/

[oracle@bak j2ee]$ ll
