我已在OS Oracle Linux 7.7上安装了Oracle Database 11gR2 虽然我尝试使用下面的命令启动服务器来启动服务器
[oracle@localhost dbhome_1]$ emctl start dbconsole
Oracle Enterprise Manager 11g Database Control Release 11.2.0.1.0
Copyright (c) 1996, 2009 Oracle Corporation. All rights reserved.
http://localhost:1158/em/console/aboutApplication
Starting Oracle Enterprise Manager 11g Database Control .... started.
------------------------------------------------------------------
Logs are generated in directory /u01/app/oracle/product/11.2.0/dbhome_1/localhost_DB11G/sysman/log
但是我尝试显示状态，然后显示EM没有运行
[oracle@localhost dbhome_1]$ emctl status dbconsole
Oracle Enterprise Manager 11g Database Control Release 11.2.0.1.0
Copyright (c) 1996, 2009 Oracle Corporation. All rights reserved.

EM Daemon is not running.

如何解决？
