US 2010/0077258 A1 · GENERATE DIAGNOSTIC DATA FOR OVERDUE THREAD IN A DATA PROCESSING SYSTEM

Abstract

Disclosed is a computer implemented method, computer program product, and apparatus for generating diagnostic data for a thread. A service processor may begin by executing the computer usable program code to allocate a first thread to a monitoring function. The service processor determines if a second thread is running, wherein the second thread is associated with an operation. The service processor obtains an object pointer from a list of running threads, wherein the object pointer references a time data structure associated with the second thread, the time data structure comprising a maximum running time interval and a check time. The service processor calculates the check time as a maximum running time interval added to an initially sampled timestamp. The service processor determines if a current time exceeds the check time. In addition, the service processor generates an error log, responsive to a determination that the current time exceeds the check time.
