1. which account does OEM use to monitor its database?
2. And If we have the password change every three months on all of the account on the database, what is the best way to handle the account that used to monitor OEM?

thanks

1.Account which you used while installing OEM, and you use this account to monitor the database through OEM.
2. Remember the password or set the preferences
