WebDistributed deadlock detection algorithms [10,11] rely on the cooperation of all the sites in the distributed database system in order to detect deadlocks. Each site in the distributed database system consists of a deadlock detector. Potential deadlock information is transmitted from one site to another. WebWhat is Spooling. Spooling is a process in which data is temporarily held to be used and executed by a device, program, or system. Data is sent to and stored in memory or other volatile storage until the program or computer requests it for execution. SPOOL is an acronym for simultaneous peripheral operations online.
