Abstract
The present invention is directed to tracking and managing failure-susceptible operations in a computer system. In a preferred embodiment, the performance of failure-susceptible operations is monitored, such that, when execution of the operating system is interrupted then restarted, it can be determined which failure-susceptible operation was in progress at the point at which execution of the operating system was interrupted. In one embodiment, this monitoring is performed using a stack data structure. When a failure-susceptible operation is invoked, an entry is pushed on the stack identifying the invoked failure-susceptible operation. On the other hand, when a failure-susceptible operation is completed, the entry identifying the completed failure-susceptible operation is popped off the stack. The failure-susceptible operation that was in progress at the point at which execution was last interrupted is then determined to be the failure-susceptible operation identified by the top entry on the stack when execution resumes. In a further preferred embodiment, subsequent attempted invocation of the operation determined to be in progress when execution was interrupted is inhibited.
