--EM的管理架构:
通过IE连接EM,EM通过监听找到Oracle!
查看em状态
[oracle@centos-fuwenchao ~]$ emctl status dbconsole Environment variable ORACLE_UNQNAME not defined. Please set ORACLE_UNQNAME to database unique name. [oracle@centos-fuwenchao ~]$ echo $ORACLE_UNQNAME [oracle@centos-fuwenchao ~]$ export ORACLE_UNQNAME=wenchaodb [oracle@centos-fuwenchao ~]$ emctl status dbconsole Oracle Enterprise Manager 11g Database Control Release 11.2.0.1.0 Copyright (c) 1996, 2009 Oracle Corporation.

查看listener状态

可以看到,监听找到了数据库,进而EM可以根据监听找到数据库!
如果监听没有认识到数据库,可以执行命令
sqlpuls / as sysdba;
alter system register;
exit
--
使用EM登录数据库
账户sys 密码****** 角色sysdba
em出了问题可以删除重建
关闭顺序:em listener oracle
启动顺序 listener Oracle em
emctl start|stop dbconsole
lsnrctl start|stop
sqlplus / as sysdba ; shutdown immediate|startup
em一旦建立好了之后,Linux服务器的主机名字不要改变,否则em重建
