Looking at the log file reveals following error...
CONFIG: ORA-20001: SYSMAN already EXISTS..
ORA-06512: at line 17
oracle.sysman.assistants.util.sqlEngine.SQLFatalErrorException: ORA-20001: SYSMAN already EXISTS..
ORA-06512: at line 17
Work around -
Perform following actions in your DB
SQL> drop user sysman cascade;
User dropped.
SQL> DROP PUBLIC SYNONYM setemviewusercontext;
Synonym dropped.
SQL> DROP ROLE mgmt_user;
Role dropped.
SQL> DROP PUBLIC SYNONYM mgmt_target_blackouts;
Synonym dropped.
SQL> DROP USER mgmt_view;
User dropped.
There is one more thing to add here is that since my repos drop operation failed earlier I have to manually drop the repos using following method..
[oracle@devtstdbsrv bin]$ pwd
/u01/app/oracle/product/11.0/db_1/sysman/admin/emdrep/bin
[oracle@devtstdbsrv bin]$ ./RepManager devtstdbsrv 1521 orcl -action drop
Enter SYS user's password :
Enter repository user name : sysman
Getting temporary tablespace from database...
Found temporary tablespace: TEMP
Checking SYS Credentials ... rem error switch
OK.
rem error switch
Dropping the repository..
Checking for Repos User ... Exists.
Repos User exists..
Clearing EM Contexts ... OK.
Dropping EM users ...
Done.
Dropping Repos User ...
Dropping Roles/Synonymns/Tablespaces ... Done.
Dropped Repository Successfully.
If this is not done then later during create repos operation you will face following error..
CONFIG: ORA-00955: name is already used by an existing object
oracle.sysman.assistants.util.sqlEngine.SQLFatalErrorException: ORA-00955: name is already used by an existing object
Now try to re-create the repository once again. We will try to create first repository and then db-control in separate steps as follows.
[oracle@devtstdbsrv dbs]$ emca -repos create

So the listener issue as described earlier during drop operation was not really a issue. It was more like a place holder error rather than actual error!!!
Now one needs to config the db-control as follows
[oracle@devtstdbsrv dbs]$ emca -config dbcontrol db
