摘要： Techniques for transferring a serialized image of data for an XML construct includes selecting a first format from multiple different XML serialization formats that represent, in a database system, data for XML constructs as a series of data units, such as a series of bytes representing characters, or a series of bits, bytes or octets representing binary values. A message is generated that includes a payload and a payload type field. The payload includes particular serialized data that represents particular data for a particular XML construct in the first format. The type field includes data that indicates the first format. The message is sent from a sending component of the database system to a different receiving component of the database system. These techniques allow the format selection to be based on characteristics of the sending or receiving components to make better use of the resources available to the two components.

摘要： A universal format is used to create a type representation of XMLType instances that are generated in various ways from various sources. An XMLType Type Tree is represented as a hierarchy of nodes, including leaf item node, composite item node, operator node, aggregate node, referred to herein as an XMLType Type Tree. An XMLType Type Tree serves as a digest of the type structure of XMLType, no matter the source of the XMLType instance or its manner of its generation and it creates one uniform abstraction of the type structure of XMLType for the data-typing analysis of XPath and XQuery during query compile time.

摘要： A method and apparatus for managing hierarchical relationships in a relational database system is provided. An “orderkey” data type, which is native within a relational database system, is disclosed. The orderkey type is designed to contain values that represent the position of an entity relative to the positions of other entities within a hierarchy. Such values represent hierarchical relationships between those entities. Values that are of the orderkey type have properties that allow hierarchy-oriented functions to be performed in an especially efficient manner. Database functions, which operate on and/or produce values that are of the orderkey type, are also disclosed. Such functions can be placed within SQL statements that a database server executes, for example. In response to executing SQL statements that contain such functions, the database server performs hierarchy-oriented operations in a highly efficient manner.

摘要： A database server that manages a database retrieves metadata that is stored, within the database, in association with a procedure that is stored in the database. Based on the metadata, a Web service definition is automatically constructed to describe the procedure as a Web service. The WSDL definition can be referenced to construct SOAP messages with the appropriate arguments and in the appropriate format which, when received, are converted to a suitable format for invoking execution of the procedure by the database server.

摘要： A flexible and extensible architecture allows for secure searching across an enterprise. Such an architecture can provide a simple Internet-like search experience to users searching secure content inside (and outside) the enterprise. The architecture allows for the crawling and searching of a variety or sources across an enterprise, regardless of whether any of these sources conform to a conventional user role model. The architecture further allows for security attributes to be submitted at query time, for example, in order to provide real-time secure access to enterprise resources. The user query also can be transformed to provide for dynamic querying that provides for a more current result list than can be obtained for static queries.
摘要翻译： 灵活可扩展的架构允许跨企业进行安全搜索。 这样的架构可以为在企业内部（和外部）搜索安全内容的用户提供简单的类似Internet的搜索体验。 该架构允许在整个企业中爬行和搜索各种或多个源，无论这些源是否符合常规用户角色模型。 该体系结构进一步允许在查询时提交安全属性，例如为了提供对企业资源的实时安全访问。 用户查询也可以被转换以提供动态查询，其提供比静态查询可获得的更多当前结果列表。

摘要： Network and storage calls are reduced by batching messages. Messages are collected from a client and sent to the gateway or backend application in one round trip. Alternatively, the messages are collected for different entities, and the batched messages are durably stored. Related messages, which may have the same sessionID, are grouped into a logical unit or session. This session may be locked to a single message consumer. A session may be associated with an application processing state as an atomic unit of work while other operations are performed on the messages in the session. Acknowledgements are accumulated by a broker on a message server, but the messages are not immediately deleted. Instead, multiple messages in a selected range are periodically truncated from a message store in a single operation. Expired messages for active sessions are proactive cleaned up to prevent sessions from reaching a quota or limit.
摘要翻译： 通过批量消息来减少网络和存储呼叫。 消息从客户端收集，并一次性发送到网关或后端应用程序。 或者，为不同的实体收集消息，并且批量消息被持久地存储。 可能具有相同sessionID的相关消息被分组为逻辑单元或会话。 此会话可能被锁定到单个消息消费者。 会话可以与作为原子工作单元的应用处理状态相关联，而对会话中的消息执行其他操作。 致谢由消息服务器上的代理商累积，但消息不会立即被删除。 相反，在单个操作中，从消息存储区定期地截断所选范围内的多个消息。 活跃会话的过期消息被主动清理，以防止会话达到配额或限制。

摘要： A first portion of an identifier can be used to assign the identifier to a slot in a first directory. The identifier can identify a cache unit in a cache. It can be determined whether assignment of the identifier to the slot in the first directory will result in the identifier and one or more other identifiers being assigned to the same slot in the first directory. If so, then the technique can include (1) using a second portion of the identifier to assign the identifier to a slot in a second directory; and (2) assigning the one or more other identifiers to one or more slots in the second directory. In addition, it can be determined whether a directory in a cache lookup data structure includes more than one pointer. If not, then a parent pointer that points to the subject directory can be removed.

摘要： Version indicators within an existing range can be associated with a data partition in a distributed data store. A partition reconfiguration can be associated with one of multiple partitions in the data store, and a new version indicator that is outside the existing range can be assigned to the reconfigured partition. Additionally, a broadcast message can be sent to multiple nodes, which can include storage nodes and/or client nodes that are configured to communicate with storage nodes to access data in a distributed data store. The broadcast message can include updated location information for data in the data store. In addition, a response message can be sent to a requesting node of the multiple nodes in response to receiving from that node a message that requests updated location information for the data. The response message can include the requested updated location information.

摘要： Search term ranking algorithms can be generated and updated based on customer settings, such as where a ranking algorithm is modeled as a combination function of different ranking factors. An end user of a search system provides personalized preferences for weighted attributes, generally or for a single instance of the query. The user also can indicate the relative importance of one or more ranking factors by specifying different weights to the factors. Ranking factors can specify document attributes, such as document title, document body, document page rank, etc. Based on the attribute weights and the received user query, a ranking algorithm function will produce the relevant value for each document corresponding to the user preferences and personalization configurations.
