Abstract: A method for managing confidence levels in a computing system is provided. The method comprises determining a first confidence level associated with a first operation performed in the computing system. The first confidence level indicates probability that the first operation was performed successfully and is calculated based on attributes of one or more components in the computing system. Once the first confidence level is determined, the first confidence level is compared to a confidence threshold for the first operation. If the first confidence level is less than the confidence threshold, a first remedial action is taken to raise the first confidence level.

Abstract: Detecting locking discipline violations on shared resources. For example, a method of detecting locking discipline violations of shared resources of a computing platform, by a testing process to be executed concurrently with one or more other processes on said computing platform, the testing process comprising: locking a shared resource of said computing platform; reading a value of the shared resource; locally storing the value of the shared resource; rereading the value of the shared resource after a predefined time period; and generating a locking discipline violation report if the value of said shared resource as reread by said rereading is different from the value of said resource as locally stored by said locally storing.
