  • Patent number: 12174830
    Abstract: Computer technology for use in a computer system including a database system including a database management sub-system, a primary database and a secondary database, with the secondary database being maintained at least approximately in synchronization with the primary database over time as changes are made to data of the primary database (for example, a database system that includes disaster recovery (DR) features). A statistics update is performed first on a standby database to determine whether query efficiency and/or query optimization really will be substantially improved by performance of the statistics update. If not, then statistics update on the primary database is postponed until a future time.

  • Publication number: 20240376627
    Abstract: An electroplating device includes a process chamber, a paddle plate and a driving mechanism. The driving mechanism is used for driving the paddle plate to move back and forth to make the paddle plate stir the electroplating solution in the process chamber when a substrate is electroplated. The electroplating device further includes a cleaning assembly and a connecting bracket. The cleaning assembly is used for spraying a cleaning solution onto the electroplated substrate. One end of the connecting bracket is connected to the paddle plate, and the other end of the connecting bracket is connected to the driving mechanism, and the driving mechanism drives the paddle plate to move back and forth via the connecting bracket. The connecting bracket is opened with a hollowed-out area, and the cleaning solution sprayed onto the substrate is collected after passing through the hollowed-out area.

  • Patent number: 12117998
    Abstract: Machine-learning-based, adaptive updating of quantitative data in a database system is provided, which includes training one or more machine learning models to facilitate adaptively updating quantitative data in the database system, and ascertaining an update urgency index for updating the quantitative data for one or more data structures of the database system. The update urgency index is representative of an urgency for updating the quantitative data for the data structure(s) and is based, at least in part, on real-time query metrics. The machine learning model(s) is used to adaptively update the quantitative data, where the adaptively updating is based, at least in part, on the ascertained update urgency index. Processing of a database query is optimized in the database system using the adaptively updated quantitative data.

  • Patent number: 11656974
    Abstract: Embodiments provide enhanced performance diagnosis in a network computing environment. In response to an occurrence of a performance issue for a node while under operating conditions, common logs for applications on the node are analyzed. The applications are respectively registered in advance for diagnosis services. The applications each register rules in advance for the diagnosis services. At a time of the performance issue, debug programs are automatically issued to generate debug level logs respectively for the applications. Debug level logs are analyzed according to the rules to determine a root cause of the performance issue. A potential solution to the root cause of the performance issue is determined using the rules, without having to recreate the operating conditions occurring during the performance issue. The potential solution to rectify the root cause of the performance issue is executed without having to recreate the operating conditions occurring during the performance issue.
