Hello
I dont see any logs or any output of the SQL queries in this discussion showing how the tempfile was dropped and the status of the tempfile in the database.
If the tempfile is shown as offline then the tempfile was not dropped. Instead it was taken offline.
It looks like the tempfile was dropped with an OFFLINE DROP clause.
By doing this it will not drop the tempfile instead it will be taken Offline and Oracle will stop accessing the tempfile. It will still be part of the database.
