WARNING: ORA-12541: TNS:no listener

Nov 18, 2013 8:52:52 PM oracle.sysman.emcp.EMConfig perform
SEVERE:

Database connection through listener failed. Fix the error and run EM Configuration Assistant again.

Some of the possible reasons may be:

1) Listener port 1521 provided is incorrect. Provide the correct port.
2) Listener is not up. Start the Listener.
3) Database service oracle is not registered with listener. Register the database service.
4) Listener is up on physical host and ORACLE_HOSTNAME environment variable is set to virtual host. Unset ORACLE_HOSTNAME environment variable.
5) Listener is up on virtual host. Set environment variable ORACLE_HOSTNAME=<virtual host>.
6) /etc/hosts does not have correct entry for hostname.

Refer to the log file at /u01/app/oracle/cfgtoollogs/emca/oracle/emca_2013_11_18_20_52_27.log for more details.
Could not complete the configuration. Refer to the log file at /u01/app/oracle/cfgtoollogs/emca/oracle/emca_2013_11_18_20_52_27.log for more details.

排除问题，确定为第六可能是原因，于是修改/etc/hosts

[root@RedHatOS ~]# cat /etc/hosts
127.0.0.1   RedHatOS(原来为空，修改)  localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
