Abstract: A system and method for a relational database system for identifying star joins in a query and for breaking the query down for bitmap ANDing. The fact table of the star join is located, and cycles between and within dimension tables are broken. Then, the minimal set of tables necessary to execute the star join is identified, and the dimension tables that should appear in the bitmap ANDing plan are also identified. A bitmap ANDing plan is then generated, or, if the query does not qualify for bitmap ANDing, a conventional execution plan is generated.

Abstract: Programming language systems commonly allow for the use of function calls within a body of program source code. Since function names are generally descriptive, it is sometimes the case that two different functions ("function instances") will have the same name, and be distinguishable by having either a different number of arguments ("arity"), or arguments of different types. Both at compile time and at run time, the possibility of error exists if there is a mismatch between the arguments required by a function and the arguments provided to the function by the function call. Methods and related apparatus, for use in programming language systems, are set forth which support compile-time type checking and run-time dispatch for overloaded functions in an environment supporting subtypes with multiple inheritance. At both compile time and run time, the method of the invention takes into consideration the types of all arguments of a function call, to select a proper function instance to execute, for a given function invocation. In accordance with the invention, a precedence ordering is made from among multiple function instances having the same name and arity. Furthermore, the methods contemplated by the invention identify at compile time the set of function instances which might be invoked due to subtype substitutions for the actual arguments. Since type errors on function invocations or variable assignments are usually indicative of a programming error, program reliability can be improved and faults that would otherwise result in run-time errors can be corrected through the use of the invention prior to program deployment.

Abstract translation: 编程语言系统通常允许在程序源代码体内使用函数调用。 由于函数名通常是描述性的，有时两种不同的函数（“函数实例”）将具有相同的名称，并且可以通过使用不同数量的参数（“arity”）或不同类型的参数来区分 。 在编译时和运行时，如果函数所需的参数与通过函数调用提供给函数的参数之间存在不匹配，则存在错误的可能性。 阐述了在编程语言系统中使用的方法和相关设备，其支持在支持具有多重继承的子类型的环境中的重载函数的编译时类型检查和运行时调度。 在编译时和运行时，本发明的方法考虑到函数调用的所有参数的类型，以便为给定的函数调用选择要执行的正确的函数实例。 根据本发明，从具有相同名称和特征的多个功能实例中进行优先级排序。 此外，本发明考虑的方法在编译时识别由于实际参数的子类型替换而可能调用的一组函数实例。 由于功能调用或变量分配上的类型错误通常表示编程错误，因此程序可靠性可以提高，否则会导致运行时错误的故障可以在程序部署之前通过使用本发明来纠正。

Abstract: An actuator for actuating a downhole mechanism in a well utilizes increased annular pressure in one instance, and a control line pressure in a second instance. The actuator has an actuating chamber in which an actuating piston moves. The actuating piston communicates with the annulus pressure on one side and with pressure in an intensified pressure chamber on the other side. A control valve locates in a control passage leading from the intensified pressure chamber to the actuator piston. A vent valve locates in a vent passage that leads from the actuator piston to the annulus. The vent valve will close when pressure in the intensified pressure chamber exceeds the annulus pressure by a selected amount. Then, at a selected higher pressure, the control valve will open, allowing the pressure in the intensified pressure chamber to act on the actuator piston. A differential area piston will supply the increased pressure in the intensified pressure chamber from the annulus when the actuator is used with a test tool. When used with the safety valve, a control line may lead from the surface to the intensified pressure chamber if an unlimited number of cycles are required.

Abstract: A method and system for distributing tasks from an external application among concurrent database application server instances in a database system for optimum load balancing, based on consensus among the instances. Each application instance identifies a task partition ownership by those in a membership group based on a time window and generates a new membership group and partition ownership based on the current partition ownership. The instance makes the new membership group and partition ownership known to other members by recoding them in the membership table and partition map. Each participation by an instance in the membership group is identified by a random number. The new membership group and partition ownership are generated and adjusted based on an average partition allocation to achieve consensus among the instances.

Abstract: A method and system for provisioning circuits on multiple parallel links with a single setup message is disclosed. A setup message specifying links in a circuit path is transmitted to switches along the circuit path. If a switch determines that a link specified in the setup message has insufficient bandwidth for the circuit, the switch substitutes a parallel link having sufficient bandwidth for the specified link in the circuit path. The setup message can indicate whether substitution for a link is permitted. This can be used to prevent substitution for links when provisioning service routes for new circuits in order to maintain diversity requirements, while allowing substitution for links when provisioning restoration routes for failed circuits in order to reduce restoration time.

Abstract: A method and system provide capacity-efficient restoration within an optical fiber communication system. The system includes a plurality of nodes each interconnected by optical fibers. Each optical fiber connection between nodes includes at least three channel groups with different priority levels for restoration switching in response to a connection failure. The system maintains and restores full-capacity communication services by switching at least a portion of the channel groups from a first optical fiber connection to a second optical fiber connection system based on the priority levels assigned to the channel groups. Service reliability is effectively maintained without to incurring additional costs for dedicated spare optical fiber equipment by improving idle capacity utilization.
