After you reconfigure EM, the port number may change. Check the command prompt.

The port number is based on the configuration file.

/U01/app/oracle/product/11.2.0/dbhome_1/sysman/config/emca. properties

DBCONTROL_HTTP_PORT_MIN = 5500
DBCONTROL_HTTP_PORT_MAX = 5519

DBCONTROL_HTTP_PORT_DEFAULT = 1158

Configure the EM port number

Emca-reconfig ports-dbcontrol_http_port 1158

Configure the proxy port number

Emca-reconfig ports-agent_port 3938

The configured file is in

/U01/app/oracle/product/11.2.0/dbhome_1/install/portlist. ini

Maybe the port number you want to configure has been allocated. You can check the log and it will automatically allocate one to you,

(The occupied directory can be deleted and not tested)

Re-configure the host name used by EM, which is the domain name corresponding to your host name, in the/etc/hosts file.
