摘要： To export source tablespaces, an auxiliary database system is created and started with a minimum configuration. Copies of versions of the source tablespaces are restored from database backups to the auxiliary database system. A copy of a version of a tablespace is referred to herein as a tablespace instance. The tablespace instances restored from database backups are recovered to a particular point-in-time. A script is then generated. The script can be executed by a database server of the destination database to import the tablespace instances.

摘要： An approach migrates database sessions from a database server on which performance and resource availability requirements are not being met to another database server. Because workload is removed from the database server not meeting these requirements, improved performance there is promoted. Furthermore, the approach switches the users in a way that attempts to keep performance and resource availability levels at the database server receiving the database sessions within goals for performance and resource availability.

摘要： An approach for reducing transport of messages between nodes of a multi-node system is presented wherein a message queue is associated with a queue service, and based on which node the message queue resides, one of the nodes is registered as hosting the associated queue service. In response to a client attempting to connect and requesting a particular queue service, the client is caused to connect to the node on which the queue service resides.

摘要： A method and system are provided for instantiating objects for participation in information sharing relationships. According to one technique, a copy of an object is made, where the copy includes all changes made prior to a particular point in time, and no changes made after the particular point in time. The copy is used to create a second object. Data that reflects the particular point in time is stored, and subsequently used to determine which changes should be applied to the second object. Data that indicates that the creation time of the second object is stored, and subsequently used to determine which changes should be applied to the original object.

摘要： A method and system are provided for duplicating at a destination site changes made to data at a source site. According to the method a plurality of streams are established between the source site and the destination site. The plurality of streams are used in parallel to propagate changes made at the source site to the destination site. A record of transactions that made changes that need to be propagated from the source site to the destination site is maintained at the source site. Before propagating changes made by a transaction to the destination site on a stream of the plurality of streams, the record of transactions is inspected to identify a set of transactions whose changes are not known to have been made permanent at the destination site. It is then determined whether the transaction could possibly depend on any transaction in the set of transactions. If the transaction could not possibly depend on any transaction in the set of transactions, then the changes made by the transaction are propagated to the destination site using one of the plurality of streams.

摘要： A method and apparatus for comparing a first set of data and a second set of data are disclosed. A subset of base data is compared to a subset of replicated data to determine discrepancies. These discrepancies are then used to modify the replicated set of data, and the replicated set of data thus becomes identical to the base set of data. Alternately, the base data is compared directly to the replicated data and differences between the base data and the replicated data are obtained. These differences are then used to modify the replicated data to become identical to the base data.

摘要： An approach generates performance grades. A performance grade is a value or set of values that indicates the relative work performance offered by a resource, such as a server in a multi-node system, relative to other resources. Performance grades are used to dynamically allocate work within a multi-node computer system. For example, performance grades are used for connection-time balancing, and to direct a database connection request to a multi-node database instance that a performance grade indicates provides better performance. Performance grade deltas are generated that reflect the incremental change in performance grade for additional sessions or work. Performance deltas are used to direct incoming sessions, to more optimally balance workload, and to deal with logon storms where a large number of connect requests arrive in a very short time period.

摘要： Communication costs are reduced in a distributed system that supports data replication with conflict detection by sending small values or nulls as replacements for field values that are not strictly used for replication or conflict detection. Specifically, nulls are propagated for new values of unmodified fields, old values of fields in unmodified groups of linked fields, and old values of fields for which conflict detection has been disabled. Flag values that indicate which actual old and new values were sent may be generated and propagated along with the replicated data.
摘要翻译： 通过发送小值或空作为不严格用于复制或冲突检测的字段值的替换，在支持具有冲突检测的数据复制的分布式系统中，通信成本降低。 具体来说，对未修改字段的新值，未修改的链接字段组中的字段的旧值以及已禁用冲突检测的字段的旧值来传播空值。 指示发送哪些实际旧值和新值的标志值可以与复制数据一起生成和传播。
