Automated or autonomic techniques for managing deployment of one or more resources in a computing environment based on varying workload levels. The automated techniques may comprise predicting a future workload level based on data associated with the computing environment. Then, an estimation is performed to determine whether a current resource deployment is insufficient, sufficient, or overly sufficient to satisfy the future workload level. Then, one or more actions are caused to be taken when the current resource deployment is estimated to be insufficient or overly sufficient to satisfy the future workload level. Actions may comprise resource provisioning, resource tuning and/or admission control.

Managing computing deployment in presence of variable workload

Embodiments of the invention provide techniques for displaying and refactoring of programs, including database statements. In one embodiment, database statements embedded in the program source are evaluated to identify statements of the source code affected by, or affecting, the changed element of the database. An indication of the statements of source code affected by or affecting the changed element of the database may be presented to a user.

Displaying and refactoring programs that include database statements

A system (and method) of detecting an error in a database interaction, includes providing information about at least one of at least first and second software systems, and a mapping between at least a portion of the at least first and second software systems, and examining the at least one of the first and second software systems and the mapping to determine an error in an interaction between the at least first and second software systems.

Method and system for detection of integrity constraint violations

A method for extending functionality of a compiler includes: receiving a first source file written in a language that supports multiple system types, wherein the first source file includes a plurality of source constructs associated with parameter types of the multiple type systems; annotating each of the plurality of source constructs with the type system from one of the multiple type systems and precise parameter type to which its associated type system belongs; retrieving type system rules corresponding to each type system referred to in the first source file from a type system loader; verifying, using the type system rules, that instances of use of variables, expressions, and methods in the first source file are appropriate with respect to the type system of annotated types associated with the source constructs; and compiling the first source file to produce a second source file including type information retained from the first source file.

Modular integration of distinct type systems for the compilation of programs

An information handling system for improving reception comprises logic for determining a target location for improved communication for a wireless telecommunication unit based in part on information representing a recent position of the wireless telecommunication unit, wherein the target location is more likely to result in better reception of wireless signals from a wireless access point. The system also includes a transceiver for receiving and transmitting signals to other users of the network. Optionally, the transceiver can be configured for receiving information representing the most recent position of the wireless unit and for transmitting directions to the wireless unit, the directions including information on how to get to the target location.

Method and system for directing a wireless user to a location for improved communication

An improved system for determining compliance between a source document structure in accordance with a source schema and a target schema includes: data storage; and a processor for executing software code. The software code causes the processor to: create a source schema description and a target schema description; receive the source document which includes an ordered tree structure with labeled elements and including a subtree; identify all corresponding element types in the source and target schemas for grouping the corresponding element types into element type pairs; classify each element type pair; and confirm compliance of the source document.

System for validating a document conforming to a first schema with respect to a second schema

A method of validating a document structured in accordance with a first schema and with respect to a second schema saves processing time by using information about relationships between the first schema and second schema and the document's conformance to the first schema to determine the document's validity in the second schema. The element type definitions of the XML or other document cast in the first schema are examined to determine if any element conforming to element types in the first schema is always invalid in the second schema. If any content conforming to always invalid element types is present in the document, the document can be immediately invalidated with respect to the second schema without further processing. Any content conforming to element types in the first schema that are subsumed by element types in the second schema can be immediately validated with respect to the second schema.

Method for validating a document conforming to a first schema with respect to a second schema

A system (and method) of detecting an error in a database interaction, includes providing information about at least one of at least first and second software systems, and a mapping between at least a portion of said at least first and second software systems; and examining said at least one of said first and second software systems and said mapping to determine an error in an interaction between said at least first and second software systems.

Detecting an integrity constraint violation in a database by analyzing database schema, application and mapping and inserting a check into the database and application

A method, computer readable medium and information processing system for projecting a representation of a document in the Extensible Markup Language (XML) format. The method dynamically creates a tree representation of an XML document based on a provided set of XPath expressions through approximate matching techniques. The projection created by the method supports all XPath axes including backward axes such as parent and ancestor. The execution of the set of XPath queries on the projected document is guaranteed to be the same as that of executing the XPath queries on the original document. The projected document typically occupies much less space than the original document.

Method and apparatus for approximate projection of XML documents

A system and method for processing documents, comprises steps of: receiving a query comprising search criteria and wherein the criteria comprise a set of constraints that specify forward or backward relations between nodes; receiving a location in the tree with respect to which the query must be evaluated; receiving at least a portion of a document; modifying the search criteria such that constraints specifying a backward relation may be reformulated into constraints specifying a forward relation and introducing a context node at a location along a forward edge origination at the root of the tree structure; processing the document using the modified criteria; and locating one or more nodes that satisfy the search criteria.

Streaming mechanism for efficient searching of a tree relative to a location in the tree

In one embodiment, the present invention is a method and apparatus for automatic system parameter configuration for performance improvement.
