Oracle : Ошибка ORA-01155


"the database is being opened, closed, mounted or dismounted"
*Cause: The requested operation needs the instance to be in a particular
state but the state is being changed.
*Action: Wait for the open, close, mount, or dismount to complete then
retry the operation. If necessary, a SHUTDOWN ABORT will always
work.
