latch levels and latch deadlock

latch levels and latch deadlock

Post by danism.. » Sun, 31 Dec 1899 09:00:00


I've some questions:

- If higher level latch is requiested in willing-to-wait mode while
holding lower level latch, will process sleep whether or not this
higher level latch is available ?

- how does process continue its processing in no-wait mode ? what is
the mechanism ? to prevent from latch deadlock, how does process
release its holding higher level latches ? is there a latch recovery ?
