摘要： A technique for migrating (e.g., “copying” or “moving”) temporary data from one session to another session is provided. While executing a workload associated with a particular session, session state is created. A subset of the session state comprises large objects that are referred to as “temporary data.” Thus, temporary data is stored in a database (instead of in the database server) and is normally deleted when the particular session is deleted. To avoid this deletion when the session state is migrated to a different session, the temporary data, in one embodiment, is saved in an external storage that is separate from the database. An external table is created in the external storage and stores the temporary data. Location information to access the external table is provided to the other session.

摘要： Techniques for migrating duration trees from a source database server (or instance) to a destination database server (or instance) are provided. A duration is a memory management construct that allows database components to group related areas of memory together. A source duration tree is captured at the source database server and combined with a destination duration tree at the destination database server. Any duration identifiers in the source duration tree that conflict with (i.e., are the same as) a duration identifier in the destination duration tree are mapped to new duration identifiers.
摘要翻译：提供了将持续时间树从源数据库服务器（或实例）迁移到目标数据库服务器（或实例）的技术。持续时间是一种内存管理结构，允许数据库组件将相关的内存区域组合在一起。在源数据库服务器上捕获源持续时间树，并与目标数据库服务器上的目标持续时间树组合。在源持续时间树中与目标持续时间树中的持续时间标识符冲突（即，与之相同）的任何持续时间标识符被映射到新的持续时间标识符。
