Abstract

A system and method for determining a master process for control of a shared system resource. The improved system requires the master process to hold exclusive access on a shared resource control file only intermittently. The master process periodically updates the shared resource control file with a new timestamp. Processes seeking resource access read the shared control file and determine whether another process has been designated master. If the interval since the latest timestamp is greater than a preset staleness interval, the shared control file is discarded and a new one created by the accessing process.
