Oracle 入门之EM配置

Oracle 11g R2 64位启动em,出现如下错误:
[root@localhost ~]# su - Oracle
[Oracle@localhost ~]$ emctl start dbconsole
Environment variable Oracle_UNQNAME not defined. Please set ORACLE_UNQNAME to database unique name. -
 

[Oracle@localhost ~]$ export ORACLE_UNQNAME=online
[Oracle@localhost ~]$ emctl start dbconsole
OC4J Configuration issue. /u01/app/Oracle/oc4j/j2ee/OC4J_DBConsole_localhost.localdomain_online not found.
问题原因为em资料库配置不正确，或者是dbcontrol没有配置好

1：重建EM资料
[Oracle@localhost ~]$ emca -repos recreate
