Patent number: 11936763Abstract: Embodiments of the present invention provide methods, computer program products, and systems. Embodiments of the present invention can identify a network request as being deferrable and embed data of the deferrable network request within a header of a suitable carrier network request for sending to a remote server. Embodiments of the present invention can receive a carrier network request with embedded data of a deferrable network request within a header of the carrier network request. Embodiments of the present invention can then parse the embedded data from the header into a separate request message for actioning at the server.Type: GrantFiled: October 28, 2020Date of Patent: March 19, 2024Assignee: International Business Machines CorporationInventors: Matthew Paul Chapman, Chengxuan Xing, Ashley Donald Harrison, Samuel David Goulden

Patent number: 11874932Abstract: Approaches presented herein enable a security risk manager embedded in an application to manage security vulnerabilities of the application. More specifically, the application comprises code entities such as components, packages, libraries, or microservices. The entities are modified as part of the application development process to have an enabled state, in which these entities are permitted to run normally when called, and a disabled state, in which these entities do not run when called but instead perform a back-out behavior such as generating an error message. At runtime, the application periodically accesses a security vulnerabilities database to check for security alerts. When a relevant security alert is found, the application changes any code entities that are affected by the security alert to the disabled state pending investigation by an operations team. The application notifies the operations team by sending a notification of the security alert to an external security monitoring tool.Type: GrantFiled: June 30, 2021Date of Patent: January 16, 2024Assignee: International Business Machines CorporationInventors: Matthew Paul Chapman, Chengxuan Xing, Ashley Donald Harrison, Vlad Balanescu

Publication number: 20240012829Abstract: An approach to implement an extract, transform and load system, a queue is provided for holding units of data between extraction and transformation. When units of data suffer a rate limit error in the load phase, they are requeued so they can be resubmitted for transformation. The contents of the queue are monitored and, if too many requeued units of data are detected in the queue, then this is taken as an indicator of an unacceptable number of rate limit errors and active pacing management is triggered. A retry schedule is defined for the requeued units of data. Extraction is temporarily halted to allow the requeued units of data to be retransformed without more units of data queuing up. Then, after the suspension is lifted, a pacing delay is inserted between subsequent extract events to avoid the same load phase bottleneck recurring.Type: ApplicationFiled: September 25, 2023Publication date: January 11, 2024Inventors: Chengxuan Xing, Doina Liliana Klinger, Alexander Robert Wood, Tom Soal

Publication number: 20230394163Abstract: A pull request from a managed cluster may be authorized by, for each managed cluster managed by the service provider, generating an encrypted pull secret for a managed cluster, assigning the generated encrypted pull secret to the managed cluster, and responsive to receiving a pull request from a managed cluster at the service provider. The pull request may have an accompanying encrypted pull secret. The pull request may also determine whether the pull request was initiated by an intended managed cluster by decrypting the encrypted pull secret assigned to the managed cluster using a decryption key.

Publication number: 20230315396Abstract: An integration flow can be improved with the use of a pattern identified from a pattern library. The identified pattern can include a snippet of nodes which are functionally equivalent to a subset of nodes in the integration flow. The pattern also lists an endpoint capable of performing the snippet of nodes. The integration flow can therefore be updated to cause the endpoint to perform the snippet of nodes.Type: ApplicationFiled: March 29, 2022Publication date: October 5, 2023Inventors: Chengxuan Xing, John Anthony Reeve, John Hosie, Benjamin Graham Thompson

Patent number: 11677810Abstract: An application configuration tool and associated method for supporting deployment of an application on a server that has a set of configurations available for applications deployed on the server. The method attempts to match every configuration required by the application to a configuration available on the server. In case of multiple candidates that match, one is selected. When there is no match an error message is generated. The method is iterated to inspect each selected configuration to identify any references contained in the selected configuration that themselves need further configurations. The iteration of inspecting and the matching to follow the references is continued until all such references are exhausted either by matching or failure to match and consequent error message generation. Finally, a configuration report is output specifying the selected configurations and, to the extent that not all required configurations have been matched to available configurations, the error messages.Type: GrantFiled: July 23, 2021Date of Patent: June 13, 2023Assignee: International Business Machines CorporationInventors: John Anthony Reeve, Doina Liliana Klinger, Chengxuan Xing, Tom Soal

Patent number: 11074122Abstract: A computer-implemented system and method detect an error in an application comprising a component having a control that is displayed in a first state on a display device. Responsive to the detecting of the error, the method comprises associating the error with the control, and, upon making this association, the method comprises automatically modifying the component at application run-time. This modification indicates that the control is no longer functional. A display operation of the component is performed where the modified component has: a) the control displayed in a second state on the component, or b) the control is removed from the component. The method may be repeated when other errors occur, and the control may be restored when the underlying error is resolved.Type: GrantFiled: August 8, 2019Date of Patent: July 27, 2021Assignee: International Business Machines CorporationInventors: Matthew Paul Chapman, Chengxuan Xing, Ashley Donald Harrison, Andrew James Daniel
