Abstract
A method includes retrieving, by a processor, a first entry from a global wait list as a current waiting lock. The method further includes decreasing, by the processor, a deadlock timer of the current waiting lock. The method further includes determining, by the processor, whether the deadlock timer equals zero. The method further includes appending, by the processor, the current waiting lock to an end of a deadlock victim selection list, if the deadlock timer equals zero. The method further includes selecting, by the processor, a victim from the deadlock victim selection list.
