    摘要： A self-managing workload repository infrastructure (or “AWR” for Automatic workload repository) which is useful for a database server to collect and manage useful system performance statistics. The AWR runs automatically to collect performance data about the operation of the database system, and stores the data that it captures into the database. The collection process is done inside the database, and the collection process is highly efficient as data is retrieved directly from the shared memory of the database kernel. The data captured allows both system level and user level analysis to be performed without unduly impacting system performance, e.g., by eliminating or reducing the requirement to repeat the workload in order to diagnose problems. The AWR is configured to automatically capture snapshots of statistics data on a periodic basis as well as purge stale data on a periodic basis. The captured performance data includes one or more of the top N (e.g., 20 or 30) statistics for activities involving a large set of objects, time-based statistics, cumulative statistics, sampled data and metrics and other data types.

    摘要： A self-managing workload repository (AWR) infrastructure useful for a database server to collect and manage selected sets of important system performance statistics. Based on a schedule, the AWR runs automatically to collect data about the operation of the database system, and stores the data that it captures into the database. The AWR is advantageously designed to be lightweight and to self manage its use of storage space so as to avoid ending up with a repository of performance data that is larger than the database that it is capturing data about. The AWR is configured to automatically capture snapshots of statistics data on a periodic basis as well as purge stale data on a periodic basis. Both the frequency of the statistics data capture and length of time for which data is kept is adjustable. Manual snapshots and purging may also be performed. The AWR captured data allows for both system level and user level analysis to be automatically performed without unduly impacting system performance, e.g., by eliminating or reducing the requirement to repeat the workload in order to diagnose problems.

    摘要： A method and apparatus for capturing database system workload and replaying that workload in a database system is provided. According to one aspect, in order to subject a test database system to the same workload to which the production database system actually would be subjected, a database server in the production system captures and records workload that the database server receives from external entities. This captured workload is processed. Processes external to a database server in the test database system send the processed workload to that database server. As a result, the test database system is subjected to the same workload to which the production database system originally was subjected. The foregoing technique permits a database administrator to determine how the production database system will fare if the difference that is present in the test database system is introduced into the production database system.

    摘要： Techniques for self-diagnosing performance problems in a database are provided. The techniques include classifying one or more performance problems in a database system. One or more values for quantifying an impact of the one or more performance problems on the database system are then determined. The quantified values are determined based on the performance of operations in the database system. A performance problem based on the one or more quantified values is then determined. A solution for the performance problem is generated and may be outputted.

    摘要： Various embodiments of the invention provide solutions to allow more sophisticated management of the relationship between a database and its clients (which can be, inter alia, end users, business applications, etc.). Merely by way of example, some embodiments can facilitate the management of work requests in a database, as well as the management of the quality-of-service in a database system. In some embodiments, an identification handle may be assigned to a database work request. A database management application can use the identification handle to identify the work request, as well, perhaps, as any related work requests. The identification handle may also identify the database (and/or an instance thereof) and/or a clustered database node, and the identification handle may be transmitted to a mid-tier application, e.g., to notify the mid-tier about the processing of the work request, changes in quality-of service, server availability, etc.
