1，删除EM
emca -deconfig dbcontrol db [-repos drop] [-cluster]
emca -deconfig dbcontrol db -repos drop -cluster
To delete Database Control configuration files using EMCA scripts, run one of the following commands:
For a single-instance database:
$ $ORACLE_HOME/bin/emca -deconfig dbcontrol db
For an Oracle RAC database:
$ $ORACLE_HOME/bin/emca -deconfig dbcontrol db –cluster
The -deconfig option removes the Enterprise Manager jobs from Scheduling before Database Control is deconfigured. Otherwise the repository, which is not dropped, could be corrupted or inconsistent if Enterprise Manager jobs were scheduled at the time Database Control is dropped. It could also cause errors during the Database Control deletionhttps://docs.oracle.com/cd/E11882_01/server.112/e25494/dbcontrol.htm#ADMIN13417
2，新建EM
emca -config dbcontrol db -repos create -cluster
使用EMCA创建EM。
[oracle@dm01db01 ~]$ emca -config dbcontrol db -repos create -cluster
