【收藏】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
