Last Friday I had a problem with a database, it is a little strange, a archive disk get full and run of free space but not error was reported. In this case the ora-00257 is always expected but no here, I don’t sure if it’s a new way of work on this release or any other condition interfered in the problem.
Below post the alert.log error, but when new connections to the database were performed any error was prompt, the connection only get hanged.
