摘要： Systems and methods are described that establish and maintain a virtual session between a client and one or more database servers. A database server establishes a first session with a client wherein establishing the virtual session with the client comprises associating a virtual session identifier (ID) with the first session, generates state information in association with the first session, and stores the state information in a repository in association with the virtual session ID. After the first session fails, a same or different database server establishes a second session with the client wherein establishing the second session with the client comprises receiving the virtual session ID from the client, accesses the state information that was stored in the repository in association with the virtual session ID, and associates the state information with the second session.

摘要： Aspects of the subject matter described herein relate to database access. In aspects, a request for access to a database is received at a node of a database cluster. Also received at the node is an intent associated with the request. If the intent is to potentially write to the database, a primary instance of the database services the request. If the intent is to read from but not write to the database, an identifier of a secondary instance of the database is sent to the requestor for use in accessing the database.
摘要翻译：本文描述的主题的方面涉及数据库访问。在方面中，在数据库集群的节点处接收到访问数据库的请求。在节点处也接收到与请求相关联的意图。如果意图潜在地写入数据库，数据库的主实例将为请求提供服务。如果意图从数据库中读取而不是写入数据库，则将数据库的辅助实例的标识符发送到请求者以用于访问数据库。

摘要： Systems and methods are described that facilitate idempotent execution of commands generated by a client for execution by a database server. Each command transmitted to the server includes a command ID generated by the client. The server attempts to execute each command and subsequently stores the command ID associated therewith in a repository along with an indication of whether the command executed successfully. When a new command is received by the server, it determines if the command ID associated therewith has already been stored in the repository. If the command ID associated with the new command has not already been stored in the repository, then the server executes the new command. If the command ID associated with the new command has already been stored in the repository and a previously-received command associated with the command ID has been executed successfully, then the server will not execute the new command.
摘要翻译：描述了促进由客户机生成的用于数据库服务器执行的命令的幂等执行的系统和方法。发送到服务器的每个命令包括由客户端生成的命令ID。服务器尝试执行每个命令，随后将与其相关联的命令ID与指示是否成功执行的指示一起存储在存储库中。当服务器接收到新的命令时，它确定与其相关联的命令ID是否已经存储在存储库中。如果与新命令相关联的命令ID尚未存储在存储库中，则服务器将执行新命令。如果与新命令相关联的命令ID已经存储在存储库中，并且与命令ID相关联的先前接收到的命令已成功执行，则服务器将不执行新命令。

摘要： A request for application information can be received from an application running in a process. The application information can be requested from an information repository, and received back from the repository in a first format. The application information can be converted to a second format, and passed to the application in the second format. In addition, the application information can be saved in the second format in a cache in the process. Also, when application information has been cached in response to a request for the information for a first user object, and a subsequent request for the application information for a second user object is received, it can be determined whether the second user object is authorized to access the application information. If so, then the application information can be fetched from the cache and returned for use by the second user object.

摘要： Systems and methodologies that enhance a Tabular Data Stream (TDS) protocol by enabling efficient transmission of a row(s) with null columns(s). An identification component employs a bit map that can be positioned at beginning of a row, to indicate to the receiving side (e.g., a client) columns that are to be sent. Accordingly, by distinguishing columns that are null from columns that are not null—followed by sending columns that are not null—transmission resources can be effectively employed.
