emctl 错误一例: OC4J Configuration issue

emctl 错误一例: OC4J Configuration issue

新装的系统经常会碰到这个问题，建完库以后想看看EM是不是正常启动

[oracle@node2 dbs]$ emctl status dbconsole

OC4J Configuration issue. /u01/app/oracle/product/11.2.3/db_1/oc4j/j2ee/OC4J_DBConsole_node2_MOMORAC not found.
[oracle@node2 dbs]$ ll /u01/app/oracle/product/11.2.3/db_1/oc4j/j2ee/OC4J_DBConsole_node2_MOMORAC
ls: cannot access /u01/app/oracle/product/11.2.3/db_1/oc4j/j2ee/OC4J_DBConsole_node2_MOMORAC: No such file or directory
[oracle@node2 dbs]$
[oracle@node2 dbs]$ cd  /u01/app/oracle/product/11.2.3/db_1/oc4j/j2ee/
[oracle@node2 j2ee]$ ll |grep OC4J_DBConsole_node2_
drwxr-xr-x 10 oracle oinstall 4096 Jun  4 18:21 OC4J_DBConsole_node2_momorac/
[oracle@node2 j2ee]$

很简单，是因为DB_UNIQUE_NAME 大小写导致的，或者建库的时候，最好各种name都用大写，省的麻烦

简单处理，创建个链接

[oracle@node2 j2ee]$ ln -s OC4J_DBConsole_node2_momorac OC4J_DBConsole_node2_MOMORAC
[oracle@node2 j2ee]$

再次查看

[oracle@node2 j2ee]$ emctl status dbconsole
EM Configuration issue. /u01/app/oracle/product/11.2.3/db_1/node2_MOMORAC not found.
[oracle@node2 j2ee]$

还是大小写，再去建个链接

[oracle@node2 j2ee]$ cd /u01/app/oracle/product/11.2.3/db_1/
[oracle@node2 db_1]$ ll|grep node2_
drwxr-xr-x  3 oracle oinstall  4096 Jun  4 18:31 node2_momorac/
[oracle@node2 db_1]$ ln -s node2_momorac node2_MOMORAC
[oracle@node2 db_1]$ ll|grep node2_
drwxr-xr-x  3 oracle oinstall  4096 Jun  4 18:31 node2_momorac/
lrwxrwxrwx  1 oracle oinstall    13 Jun  6 14:29 node2_MOMORAC -> node2_momorac/
[oracle@node2 db_1]$

然后再次检查

[oracle@node2 db_1]$ emctl status dbconsole
