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. [oracle@bak ~]$ cd /u01/app/oracle/product/10.2.0/db_1/oc4j/j2ee/ [oracle@bak j2ee]$ ll total 24 -rw-r--r-- 1 oracle oinstall 256 Aug 22 16:42 deploy_db.ini drwxr-x--- 15 oracle oinstall 4096 Aug 22 16:29 home drwxr-x--- 9 oracle oinstall 4096 Aug 22 16:24 isqlplus drwxr-x--- 3 oracle oinstall 4096 Aug 22 16:24 oc4j_applications drwxr-x--- 5 oracle oinstall 4096 Aug 22 16:24 OC4J_DBConsole drwxr-x--- 7 oracle oinstall 4096 Aug 25 11:25 OC4J_DBConsole_zlm_ora10g
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 total 24 -rw-r--r-- 1 oracle oinstall 256 Aug 22 16:42 deploy_db.ini drwxr-x--- 15 oracle oinstall 4096 Aug 22 16:29 home drwxr-x--- 9 oracle oinstall 4096 Aug 22 16:24 isqlplus drwxr-x--- 3 oracle oinstall 4096 Aug 22 16:24 oc4j_applications drwxr-x--- 5 oracle oinstall 4096 Aug 22 16:24 OC4J_DBConsole drwxr-x--- 7 oracle oinstall 4096 Oct 20 10:58 OC4J_DBConsole_bak_ora10g [oracle@bak j2ee]$ emctl status dbconsole
