Resource integrity during partial backout of application updates

摘要

In response to failure of an application that initiated updates to a group of operational system resources without the updates being successfully committed, available non-committed pending update operations are ignored for any of the group of operational system resources determined to be in a fully functional data indexing and access state. For each physically inconsistent operational system resource that was left in a non-fully functional data indexing and access state as a result of the failure of the application, a portion of available pending updates are performed to change the respective physically inconsistent operational system resource to a partially backed out operational system resource with the fully functional data indexing and access state. Remaining available pending updates are ignored for the respective partially backed out operational system resource after the respective fully functional data indexing and access state is achieved to expedite system restart.

1. A method, comprising:
by a processor in response to failure of an application that initiated updates to a plurality of operational system resources without the updates being successfully committed:
ignoring available non-committed pending update operations for any of the plurality of operational system resources determined to be in a fully functional data indexing and access state after the failure of the application; andfor each physically inconsistent operational system resource that was left in a non-fully functional data indexing and access state as a result of the failure of the application:
performing a portion of available pending updates to change the respective physically inconsistent operational system resource to a partially backed out operational system resource with the fully functional data indexing and access state; andignoring any remaining available pending updates for the respective partially backed out operational system resource after the respective fully functional data indexing and access state is achieved to expedite system restart.
