11.2 rac emctl start dbconsole OC4J Configuration issue

某RAC数据库的em在服务器重启之后,手动执行启动不能成功,错误信息如下:

[oracle@jyrac1 ~]$ emctl start dbconsole
OC4J Configuration issue. /u01/app/oracle/product/11.2.0/db/oc4j/j2ee/OC4J_DBConsole_jyrac1_rac not found. 

上面的信息显示找不到OC4J_DBConsole_jyrac1_rac

查看em配置信息:

[oracle@jyrac1 ~]$ emca -displayConfig dbcontrol -cluster

如是,检查OC4J_DBConsole_jyrac1_rac目录是否存在:

[oracle@jyrac1 ~]$ cd /u01/app/oracle/product/11.2.0/db/oc4j/j2ee/
[oracle@jyrac1 j2ee]$ ls
deploy_db_wf.ini  oc4j_applications  OC4J_DBConsole_jyrac1_jyrac  OC4J_Workflow_Component_Container   utilities
home              OC4J_DBConsole     OC4J_DBConsole_jyrac2_jyrac  OC4J_Workflow_Management_Container

发现确实不存在,但是存在类似的目录(OC4J_DBConsole_jyrac1_jyrac) ,如是打算copy一份:

[oracle@jyrac1 j2ee]$ cp OC4J_DBConsole_jyrac1_jyrac OC4J_DBConsole_jyrac1_rac

再次启动em,发现缺少jyrac1_rac目录:

[oracle@jyrac1 j2ee]$ emctl start dbconsole
EM Configuration issue. /u01/app/oracle/product/11.2.0/db/jyrac1_rac not found. 

在目录/u01/app/oracle/product/11.2.0/db/发现了类似的jyrac_jyrac目录:

[oracle@jyrac1 db]$ ls -lrt
....
drwxr-----  3 oracle oinstall  4096 Nov 22 19:37 jyrac2_jyrac
drwxr-----  3 oracle oinstall  4096 Nov 22 19:38 jyrac1_jyrac
drwxr-xr-x  7 oracle oinstall  4096 Nov 22 19:39 install
drwxr-----  3 oracle oinstall  4096 Nov 22 19:40 jyrac1_jyrac1
drwxr-xr-x  2 oracle oinstall  4096 Nov 23 08:18 dbs
drwxr-----  3 oracle oinstall  4096 Nov 23 14:36 jyrac1_rac

如是打算copy一份jyrac-rac

[oracle@jyrac1 db]$ cp -r jyrac1_jyrac jyrac1_rac

再次启动EM

[oracle@jyrac1 db]$ emctl status dbconsole

不必须重新创建EM,到此完成。
