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： Techniques for debugging a computer program that includes multiple modules executing on multiple machines include receiving, at a unifying component, first data from a first machine. The first data indicates debugging information generated by the first machine. Second data is also received at the unifying component from a second machine. The second data indicates debugging information generated by the second machine. Based on the first data and the second data, third data is formed indicating a single integrated representation of debugging information for the computer program. The unifying component allows debugging information from several machines to be integrated and then presented to a user through a single debugger client.

摘要： Techniques for debugging a computer program that includes multiple modules written in multiple languages allow machines for the multiple languages to interface with a single debugger client using a standard interface. The techniques include storing a mapping that maps language constructs of a first language into language constructs of a second language. While a first machine is executing a first module that is written in the first language, the mapping is used to generate debugging information based on language constructs of the second language. The debugging information is sent to a debugger process designed for debugging programs written in the second language.

摘要： A database may facilitate zero-downtime upgrades by concurrently maintaining multiple editions of database objects for use by both pre-upgrade and post-upgrade clients of a database application. Operations performed within the database are associated with an edition based on, for example, an initiating client or transaction. When an operation references an object or data, the database automatically performs the operation using the object or data associated with the edition with which the operation is itself associated. The database may determine the associated edition without explicit identification of the associated edition in a query or in code. Thus, no client or stored procedure code changes are necessary to reflect a new edition added during an update. Data changes in one edition may be automatically and immediately propagated to the other edition through the use of cross-edition triggers, thereby allowing both pre-upgrade and post-upgrade clients to remain fully functional throughout an upgrade.
摘要翻译：数据库可以通过同时维护数据库对象的多个版本来促进零停机升级，供数据库应用程序的升级前和升级后客户端使用。在数据库内执行的操作与基于例如发起客户端或事务的版本相关联。当操作引用对象或数据时，数据库将使用与操作本身相关联的版本相关联的对象或数据自动执行操作。数据库可以确定相关版本，而无需在查询或代码中显式标识相关联的版本。因此，不需要客户端或存储过程代码更改来反映更新期间添加的新版本。一个版本中的数据更改可能会通过使用跨版本触发器自动立即传播到其他版本，从而允许升级前和升级后客户端在升级过程中保持全面的功能。
