Avoiding failure repetition in data processing includes storing a sequence of circumstances leading up to a previous failure, monitoring circumstances in a current process, matching a sequence of circumstances in the current process to a stored sequence of circumstances, and applying rules to determine if the current process should proceed.

Failure repetition avoidance in data processing

A multithreaded computing environment for capturing diagnostic data includes initiating a trap delay component having a delay threshold in response to a monitor determining that the computing environment is in a predetermined invalid state. The multithreaded computing environment for capturing diagnostic data also includes recording, by a first thread, diagnostic data for the computing environment. The trap delay component delays the step of recording diagnostic data until the monitor determines that the predetermined invalid state has been repeated for at least one of a total count or a period corresponding to a predetermined indicator that it is a state other than a transient state of the computing environment. The transient state corresponds to a transition of the computing environment by one or more other threads from a first valid state to a second valid state.

Diagnostic data capture in a computing environment

A method in a multithreaded computing environment for capturing diagnostic data, the method comprising the steps of: in response to a determination that the computing environment is in a predetermined invalid state, a first thread recording diagnostic data for the computing environment, wherein the determination includes a verification that the invalid state corresponds to a state other than a transient state of the computing environment corresponding to a transition of the computing environment by a second thread from a first valid state to a second valid state. An apparatus and computer program element for providing such diagnostic data capture are also provided.
