Introduction

The locking protocol supports page level locking only for simplicity. The lock page class supports lock_page, unlock_page, unlock_all_pages,and upgrade_lock. It support IS,IX,S,X lock modes. It detects deadlocks and returns an error code Restart if we have been killed because of a deadlock. It is the transactions responsibility to abort itself on receiving a Restart error from any of the lock manager functions.
