An aspect includes receiving a transaction scope generated for a process in response to processing in a critical section and receiving collected data related to the process. Requests are generated using the collected data. The requests and data are stored as pending items chained together to form an ordered list in a private storage during critical section processing. The requests are processed based on the transaction scope, the processing including implementing a check of the process for any pending items in response to a transaction scope application programming interface being called or other processing relating to the pending items. The pending items are processed in the order they are created by using the ordered list. One of the requests is a rollback request that includes at least one of removing the pending items from the private storage, releasing the private storage for all pending items, and resuming normal processing.

Method for managing control-loss processing during critical processing sections while maintaining transaction scope integrity

According to one or more embodiments, a system and computer implemented method for managing critical section processing are provided. The method includes generating, using a processor, a transaction scope for a process in response to processing in a critical section, collecting data related to the process, generating, using the processor, a request using the collected data, storing the request and data as a pending item in a private storage during critical section processing, and processing, using the processor, the request based on the transaction scope.
