启动监听:
$ netstat -tlnp | grep 1521
$ lsnrctl
LSNRCTL> help
$ lsnrctl status
$ lsnrctl stop
$ netstat -tln | grep 1521

$ lsnrctl status
em
启动EM:
$ netstat -tlnp | grep 1158
$ echo $ORACLE_SID
orcl
$ echo $ORACLE_UNQNAME
orcl
如果没有设置ORACLE_UNQNAME:
$ export ORACLE_UNQNAME=orcl
或
$ vi .bash_profile
export ORACLE_UNQNAME=orcl
$ . .bash_profile
确保主机名正常解析:
$ cat /etc/hosts
$ emctl status dbconsole
$ emctl stop dbconsole
$ emctl start dbconsole
查看oem的端口:
$ find /u01 -name portlist.ini
重新配置em:
$ emca
$ emca -deconfig dbcontrol db
$ emca -config dbcontrol db
