摘要: Approaches described herein may be used for provisioning of databases that requires a bulk transfer of data within a distributed computing environment, such as a grid. The approaches do not require the manual intervention of a DBA to, for example, transfer a tablespace between the file systems of operating systems. Instead, the tablespaces may be provisioned automatically and dynamically by a grid computing system whenever it determines the need to dynamically provision a database. In addition, as copies of tablespaces are provisioned, synchronization mechanisms can also be automatically provisioned to keep the tablespaces and their copies in sync.

摘要: Techniques for making a replica of a particular group of database objects on a particular node of a network include receiving, during a transfer period, a first copy of the particular group of objects at the particular node from a first node on the network. The particular node receives, from a second node on the network, data indicating changes to the particular group of database objects on the second node, where the changes indicated in the data are changes that were made at the second node during the transfer period. The first copy of the particular group of database objects is modified based on the data indicating changes.

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.
摘要翻译: 提出了一种用于减少多节点系统的节点之间的消息传输的方法,其中消息队列与队列服务相关联,并且基于消息队列所在的哪个节点,其中一个节点被注册为托管关联的队列服务 。 响应于客户端尝试连接并请求特定队列服务,导致客户端连接到队列服务所在的节点。

摘要: Described herein are various approaches that allow rules to be used to specify actions, that alleviate the complexity and burden of developing and maintaining rules in a rules-based messaging system, and that provide more efficient ways of evaluating rules. The approaches allow rules to specify user-defined transformation functions for transforming messages, to specify when and how to perform row migration, and to specify other types of actions. Rules are grouped into rule sets. Several types of rule sets, referred to as positive and negative rule sets, allow users to use rules that are less complex to develop and maintain. Rule sets are evaluated more efficiently by attempting to evaluate the rule set with less information than is needed to evaluate all the rules in the rule set. Also, the results of rules evaluations that are based on a set of values are cached for later retrieval.

摘要: In some messaging system architectures, messages can cycle back to the originator of a message, who may then propagate the message, causing the cycle to be repeated. Described herein are techniques that use rules and fields in a redo log, to manage message flows such that undesired cycles are prevented. The techniques may be used in messaging systems that have various topologies.

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.
