Abstract: Embodiments of the present disclosure relate to rollback of services with a global variable change. Embodiment techniques detect that at least two of a plurality of services in a transaction are executed to change a value of a first global variable. Tracing information is obtained to indicate a first order in which the at least two services change the value of the first global variable during execution of the plurality of services. In response to a failure of the transaction, a rollback execution plan for a plurality of compensating services is determined at least based on the tracing information, where the plurality of compensating services are configured to compensate for the plurality of services respectively. The plurality of compensating services subsequently executed according to the rollback execution plan.

Abstract: A method, computer program product, and computer system for processing instances of message sequences. Two or more instances are received. Each instance has an instance number and an associated instance Id. Each instance includes a stream of one or more messages. Each message in each stream is associated with a respective task. All messages in the two or more instances whose respective tasks have been completed are distributed into partitions in the broker. Different messages in each instance of at least one instance are distributed into different partitions. The messages distributed in the partitions include parallel task messages. The parallel task messages are sequenced by being grouped by the instance number or instance Id and are sequentially ordered in each group in an ascending order of a timestamp of arrival of each parallel task message at the broker. The parallel task messages in each instance are dispatched to a service.

Abstract: 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.

Abstract: Embodiments of the present invention provide methods and systems for simulating variable changes during runtime of a process. The method includes recording variable changes and process context, and filtering sensitive content from the variable changes and process context. The recorded variable changes are recorded into a timeline containing the change in values to the variable changes, which is executed in a simulation environment, in order to debug the process.
