Oracle em 无法启动,报not found错误

Oracle 11g r2安装完，建完库之后，启动em 报OC4J_DBConsole_source_ora11g not found的错误，em起不来。

[oracle@source ~]$ emctl start dbconsole

OC4J Configuration issue. /oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole_source_ora11g not found.

由于是新环境，重新创建资料档案库，并重新配置数据库control

[oracle@source admin]$ emca -repos drop --删除当前的资料库
