How To Disable Connections or Freeze Database
I have no need to do so right now but I'm curious what the recommended process would be if there's an issue with Oracle 11g & one had to keep the database engine up and running but stop all users from connecting while 'X' was investigated. Do you guys have any recommendations (examples) on standard / simple procedure to stop users from connecting to Oracle 11g and querying the database or altering the database?
Thanks for any info and like I said, this is a hypothetical question as to what would one do if this issue came up. I don't have an actual performance issue that requires me from limiting database access.
Thank you!
