A technique for handling server session requests in a system having a plurality of servers is disclosed. In one embodiment, the technique includes receiving a request to create a session on one of the plurality of servers. In response to the request, a primary session is created on a first of the plurality of servers. After the primary session is created, at least one other of the plurality of servers are notified that the primary session has been created. Such notification allows for a backup session on the at least one other of the plurality of servers to take over for the primary session upon a failure on the first of the plurality of servers.

A technique for limiting access to the resources of a system is disclosed. In one embodiment, wherein the system has a server for processing requests, and wherein the server supports a plurality of projects, the technique includes receiving a request to access the resources of the system. The request is denied based upon an application level and a setting level, wherein the application level is associated with one of a plurality of functional layers within the system that is affected by the request, and wherein the setting level is a limiting value associated with one of the server alone and the server with one or more of the plurality of projects. The limiting value limits an operation on one of the plurality of functional layers, thereby limiting access to the resources of the system.

A technique for project partitioning in a cluster of servers is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for partitioning a plurality of projects among a cluster of servers. The method may comprise determining a status of project partition among the cluster of servers. The method may also comprise generating a partition plan for re-partitioning the plurality of projects among the cluster of servers based at least in part on the status and a partition policy, wherein the partition policy comprises one or more rules selected from a group consisting of a user specified project-server association rule, a weighted balancing rule, and a project redundancy rule. The method may further comprise communicating the partition plan to each of the cluster of servers. The method may additionally comprise causing the plurality of projects to be re-partitioned among the cluster of servers based on the partition plan.

The methods and systems of the invention provide for processing of jobs, that comprise one or more reports to be processed in a reporting system, by assigning a priority to a job. The priority may include a queue or a queue set priority, as well as a sub-queue priority in accordance with some embodiments of the methods and systems of the invention. Once the priority is assigned, the job is placed into a selected queue, selected from a plurality of possible queues, based on the queue priority assigned to the job. The job may also be designated to a particular sub-queue within the selected queue, i.e., based on the sub-queue priority. Then, the job is processed based on the priority.

A method and system for guiding drilling into a report are disclosed. Through the use of the invention, a user can drill within a first report dimension or from the first report dimension into a second report dimension. Additionally, a drill map providing a plurality of drilling paths is associated with each report. The system of the invention includes drill transformation tools and drill map management tools for assisting a user in navigating through report instances.

Database report generation technology for handling a single logical query that requires data that is physically located in two different sources. The system uses intelligent push-down joins, which move data from one source to the other and join data within that source. The system dynamically determines which direction to move data depending on how the data is used in a query.
摘要:
A technique for exporting results from a reporting system report in a format type including a datamart, PDF file, flat file, Excel™ file, HTML file, and XML file or in another relational database management system (RDBMS) format. In one embodiment, the technique is realized through a method and a system for automatically exporting results from a business intelligence, OLAP, or other reporting system. One embodiment of the present invention involves a method of enabling a user to designate a report desired for execution as an export-report. When the report is processed, the report is exported into a datamart or other format and made available for access by the user through one or more different types of user devices. The user may then further manipulate or export the results from the datamart to a file type as desired.

A system and method for syntax abstraction in query language generation in an online analytical processing system, a business intelligence system, a reporting system, or a data mining system. The system generates one or more query language statements that can be run against one or more data sources to return a desired data result set. The system includes a syntax pattern selector module and a statement assembly module. The syntax pattern selector module selects a syntax pattern corresponding to a desired function and a syntax standard. The statement assembly module populates the syntax pattern with an argument data set associated with the desired data set. The result is the generation of one or more query language statements with the correct function, syntax, and data parameters to return the desired data result set from the data sources. A method and medium having processor readable code therein are also described.

A method and system is provided for exchanging information over a computer network. A network server computer system receives a query request from at least one client computer system over a computer network. The query request is formatted into an extensible markup language query document according to an extensible markup language document application program interface. The extensible markup language query document is transmitted to at least one business intelligence server computer system. The at least one business intelligence server computer system retrieves the information requested in the extensible markup language query document from at least one data storage device.
