I am trying to create a standby database using oracle's enterprise manager gird control. I have to specify the login credentials of the host machine that houses the production and the standby. For some reason it only accepts my login credentials once when it gets to the next step it gives a Remote Operation Error - ?. this is for the server that holds the standby. I can log into the production server with no problems. Is there a reason why I am getting this error and how can I fix it?
