Abstract: This disclosure describes a trace debugger (TDB) that is used for database workload replay and database debugging. The TDB maintains consistency through synchronization of the state between the database and a corresponding database trace replay. The TDB can provide a sliding window environment for code block execution and global context sharing. The TDB can be used to interactively analyze and troubleshoot various types of database problems by debugging the database itself, query code (e.g., SQL), performance, end-to-end execution, and plan traces, which can be recorded using scripts. In some implementations, the TDB also provides reverse debugging for historical database state analysis, and/or incremental debugging for dynamic editing and debugging within a session without the need to exit the debugger and perform a full rebuild of the code.

The present application, which does not need a special allocation of approach of the radiation source and the radiation detection apparatus, conveniently effectuates scanning inspection of a container, and improving the inspection efficiency.

Abstract: Described herein is a technology which facilitates an effective and efficient management of a data center. In one implementation, the data center includes a container cloud manager which embeds container framework, such as Docker framework to manage App images and containers of the data center. An App image is packed back to a container which starts when the App image is requested. The use of container is lightweight and starts fast, avoiding the need for installation of the App. Furthermore, the data center is a distributed management system, which includes multiple copies of an App image as well as multiple copies of the cloud container manager. This ensures continuous operation of the data center.

Abstract: This invention relates to a movable divided inspection system and method, wherein the scanning inspection system comprises a first radiation source, a first detection means, a first automated guided vehicle and a second automated guided vehicle. The first radiation source is mounted on the first automated guided vehicle. The first detection means is mounted on the second automated guided vehicle. The first automated guided vehicle and the second automated guided vehicle are able to drive the first radiation source and the first detection means to a preset scan inspection position, so as to form a scanning passage for passage of an article to be scanned between the first and second automated guided vehicle, such that scanning inspection of said article to be scanned is realized by relative movement of said article to be scanned with reference to said first automated guided vehicle and said second automated guided vehicle.

Abstract: Described herein is a container framework which includes a flexible job management platform for managing jobs of the data center. The flexible job management platform is based on an embedded HANA container service, such as Docker service, in the container cloud manager. The flexible job management platform can isolate various types of jobs running on containers as well as mix various jobs for efficient usage of hosts or resources in the data center. The flexible job management platform supports fault tolerance, job pre-emption or other job management functions. The flexible job management platform includes a job scheduler and container cloud manager. The flexible job scheduler leverages the data center's resources, including networking, memory, CPU usage for hosts load balance by utilizing hybrid job scheduling. In addition, the flexible job scheduler enables monitoring and analysis of jobs by utilizing container service, such as Docker service.

Abstract: Disclosure is a framework for providing microservices for database with embedded container service in a container cloud platform. The framework includes a container cloud manager for performing distributed management of resources in a data center. The container cloud manager includes an orchestrator with a flexible job scheduler and operator pool. The flexible job scheduler and container cloud master form a flexible job management platform for managing jobs of the data center. The flexible job management framework can isolate various types of jobs as well as mix various jobs for efficient usage of hosts or resources in the data center. The operator pool includes optional components of a database. The orchestrator facilitates quick customization and release of database products, such as HANA database with optional services, as requested by a user in the container cloud platform.

Abstract: A scanning and imaging apparatus comprises a ray source configured to generate an X-ray and a detection device configured to receive an X-ray transmitted through an inspected object, wherein the ray source is configured to image the inspected object by emitting the X-ray to the inspected object. A radioactivity detector is configured to detect whether the inspected object comprises radioactive material synchronously with the process of scanning implemented by the scanning and imaging apparatus. In a case that the radioactivity detector detects radioactive material, an actual position of the radioactive material in an X-ray image of the inspected object obtained by the scanning and imaging apparatus is marked in the image. The above solutions improve the accuracy of displaying the position of the radioactive source in the X-ray image. Further, inspection of radioactive material can be implemented while scanning an image.
