How to upgrade dbconsole after manual database upgrade without re-creating

Recently i been involved in upgrading the database from 11.2.0.2 to 11.2.0.4 , and client was using dbconsole , I was end up learning something new ( as in past all my client always happen to be using grid control not dbconsole) , specially with upgrade assignments.



When i google arround to see the best practice to dbconsole upgrade, i found some notes on upgrade mostly recommending to deconfig the repository( drop) and create the dbconsole confiugration again.


Here is how you can simply upgrade the dbconsole with single commad (very simple ).


Set env to new  ORACLE_HOME

Pls note ORACLE_HOME for the database to be upgraded is $OLD_ORACLE_HOME .

$emca -upgrade db
