A method, computer system, and computer program product for determining a candidate patch for computer software is provided. According to a method, fingerprint(s) of patch(es) for a computer software is obtained first, wherein a fingerprint of a patch comprises function(s) being revised in the computer software if the patch is installed into the computer software. Then whether every function in the obtained fingerprint(s) of patch(es) has been called is monitored in response to beginning of execution of the computer software along to code path(s) related to bug(s). And at last candidate patch(es) is determined in response to end of the execution of the computer software along to the code path(s) related to the bug(s), wherein every function in the fingerprint of the candidate patch(es) has been called during the execution of the computer software.

Determining candidate patches for a computer software

A process instances guard system for managing the execution of process instances based on statuses of other process instances in a business process management (BPM) engine is disclosed. The process instances guard system provides a plurality of policies for managing the execution of process instances. When a status change event related to an existing process instance is received, the process instances guard system matches the existing process instance with a policy. After determining that the existing process instance matches the prerequisite condition of a policy, the process instances guard system determines that a plurality of existing process instances match the policy target descriptor of the policy, and executes the action of the policy on the plurality of existing process instances.
