I've successfully restored RMAN database backups from Production machine to a standalone machine. But After configuring the EM it is not showing instance information (See attached image). EM Configuration & listener/EM status is appended below. Pl guide me how to rectify this issue. Note: I've changed server/domain for security purpose.


EM Configuration:
1. Shutdown the "OracleDBCosolemyserver" service. 

2. Connect in SQLPLUS as sysdba and shutdown database.
	SHUTDOWN IMMEDIATE;

3. Startup the database as:
	STARTUP RESTRICT;

4. Start the dbconsole service from the services panel. 

5. Open sqlPlus and login as SYSDBA. Execute following sequence of scripts:


	EXEC sysman.emd_maintenance.remove_em_dbms_jobs;
	EXEC sysman.setEMUserContext('',5);
	REVOKE dba FROM sysman;

	DECLARE
	    CURSOR c1 IS
	      SELECT owner, synonym_name name
	      FROM   dba_synonyms
	      WHERE  table_owner = 'SYSMAN';
	BEGIN
		FOR r1 IN c1 LOOP
			IF r1.owner = 'PUBLIC' THEN
				EXECUTE IMMEDIATE 'DROP PUBLIC SYNONYM '||r1.name;
			ELSE 
				EXECUTE IMMEDIATE 'DROP SYNONYM '||r1.owner||'.'||r1.name;
			END IF;
		END LOOP;
	END;
	/

	DROP USER mgmt_view CASCADE;
  
	DROP ROLE mgmt_user;
  
	DROP USER sysman CASCADE;
  
	ALTER SYSTEM DISABLE RESTRICTED SESSION;

	alter user dbsnmp identified by MANAGER;

6. Carefully edit following commands by changing host name and passwords and run in Command Prompt:

	D:\app\hashmi\product\11.2.0\dbhome_1\BIN\emca.bat -deconfig dbcontrol db -repos drop -silent -DB_UNIQUE_NAME myserver -PORT 1521 -EM_HOME D:\app\hashmi\product\11.2.0\dbhome_1 -LISTENER LISTENER -SERVICE_NAME myserver.domain -SYS_PWD MANAGER -SID myserver -ORACLE_HOME D:\app\hashmi\product\11.2.0\dbhome_1 -DBSNMP_PWD MANAGER -HOST myserver -LISTENER_OH D:\app\hashmi\product\11.2.0\dbhome_1 -LOG_FILE D:\app\hashmi\diag\rdbms\myserver\myserver\trace\emConfig_drop.log -SYSMAN_PWD MANAGER
	
	D:\app\hashmi\product\11.2.0\dbhome_1\BIN\emca.bat -config dbcontrol db -repos create -silent -DB_UNIQUE_NAME myserver -PORT 1521 -EM_HOME D:\app\hashmi\product\11.2.0\dbhome_1 -LISTENER LISTENER -SERVICE_NAME myserver.domain -SYS_PWD MANAGER -SID myserver -ORACLE_HOME D:\app\hashmi\product\11.2.0\dbhome_1 -DBSNMP_PWD MANAGER -HOST myserver -LISTENER_OH D:\app\hashmi\product\11.2.0\dbhome_1 -LOG_FILE D:\app\hashmi\diag\rdbms\myserver\myserver\trace\emConfig_recreate.log -SYSMAN_PWD MANAGER

7. R-start the dbconsole service from the services panel 

8. Install following flash componenets for browser:
	install_flash_player_23_active_x
	install_flash_player_23_plugin
	install_flash_player_23_ppapi

9. Open EM in internet explorer and add link to trusted websites.

This happens repeatedly with the DB Console. Don't worry about it, just stop trying to use it. Note that DB Console does not exist in release 12.

Removing and re-installing it will not help, as you have found. I do remember that sometimes it doesn't stop correctly and that did seem to trigger the problem. After stopping it, check that there are no Java processes or perl processes running. It there are, kill them. Then try starting it again. No promises, but that might be the problem.

The problem was traced to be a network problem instead of database configuration. When I ping the database server using:
ping -a <IP>
It didn't displayed the domain so I re-joined the domain of database server, performed same steps to configure EM and it succeeded.

Thanks.
