摘要： A cache with a database system that contains a subset of the objects stored in another database system. The cache database system responds to a request that contains a reference to an object that is not in the cache by redirecting the request to the other database system when the request is executed in the cache's database system. Redirection is done by rewriting requests that refer to objects that are not in the cache. In one kind of rewriting, a cursor is marked to indicate redirection, and when the cursor is executed in the cache database system, it is redirected to the other database system for execution. In the other kind, calls to stored procedures that are not present in the cache database system are rewritten as remote procedure calls to the stored procedures in the other database system.
摘要翻译：包含数据库系统的缓存，其中包含存储在另一个数据库系统中的对象的子集。缓存数据库系统通过在请求在缓存的数据库系统中执行请求时将请求重定向到其他数据库系统来响应包含对不在缓存中的对象的引用的请求。重定向是通过重写引用不在缓存中的对象的请求来完成的。在一种重写中，光标被标记为指示重定向，当光标在高速缓存数据库系统中执行时，将其重定向到另一个数据库系统执行。在另一种类型中，对高速缓存数据库系统中不存在的存储过程的调用被重写为对其他数据库系统中的存储过程的远程过程调用。

摘要： Various embodiments of the invention provide solutions to facilitate the management and/or automation of various database tasks, in particular system tasks. Merely by way of example, some embodiments provide methods systems and/or software products that can facilitate automation of such tasks. In accordance with certain embodiments, a maintenance window may be defined. The maintenance window can provide an opportunity for system tasks (and/or other tasks, especially those that consume significant database resources) to execute without significantly impacting the usability of the database. In particular embodiments, a maintenance window may be defined to coincide with a period of relatively low user activity. In some cases, a maintenance window may be implemented in conjunction with a job scheduler and/or a resource manager. Merely by way of example, a resource manager might allocate relatively more system and/or database resources to system tasks during the maintenance window, and/or a job scheduler may schedule system tasks to execute during the maintenance window.
