Abstract: Techniques for requirements definition using interactive prototyping are described, including receiving an input from a client, wherein the client is installed on a first computer in data communication with an application simulation server implemented on a second computer, the input being manipulated to graphically identify a requirement for an application being generated using the first computer and the second computer, evaluating the input to identify executable program code associated with the requirement, transforming the input into the executable program code, wherein the application is designed by providing input at the first computer and simulated using the executable program code on the second computer, and generating an interactive simulation of the application by running the executable program code in a simulation environment on the second computer and displaying the application on the first computer, including one or more interfaces associated with the application.

Abstract: A database system providing high performance database versioning is described. In a database system employing a transaction log, a method for restoring databases to a consistent version comprises steps of: providing a shared cache storing database blocks for use by multiple databases; for a read-only transaction of a given database, creating a cache view of the shared cache using the given database's transaction log, the cache view comprising particular database blocks of the shared cache that record a view of a particular version of the database at a given point in time; creating a shadow cache for storing any database blocks that overflow the cache view; and in conjunction with the cache view and the shadow cache, preserving a logical undo operation for the read-only transaction of the given database, so as to allow the given database to be restored to a transactionally consistent version.

Abstract: Methods and systems consistent with the present invention provide an improved software development tool which allows a developer to receive an identification of a data structure with an attribute field in a database, determine whether the data structure is associated with source code, if the data structure is associated with the source code, determine whether an attribute field of the data structure is associated with an attribute in the source code, and if the attribute field is not associated with the attribute in the source code, generate the attribute in the source code from the attribute field.

Abstract: The present invention is directed to a method and system for interfacing with various monitoring information sources from one or more computer systems with minimal user input. Each computer system may include one or more computers as well as any number of devices such as networking devices. Expert knowledge may be embedded in the data source monitoring software. These sources can later be used by data collection tools in order to extract monitoring information and present the information to the user or use it in another way (such as storing it or raising an alert when a certain monitored value exceeds a threshold). Furthermore, the user may decide which sources of information should be monitored by the data collection tools. The user may also use the present invention in order to inform him/herself of the configuration of the system he/she is monitoring.

Abstract: A method for facilitating network communications from one or more independent execution threads by a dedicated worker thread. Because an operating system is not designed for use with a large number of threads, such a system requires the use of multiple computers for simulating a large number of virtual users. This increases complexity, as well as cost. The present invention reduces the number of threads needed, which reduces resource needs, and in turn increases the number of virtual users that can be simulated. According to the present invention, a worker thread uses non-blocking function calls to efficiently handle requests for network operations.

Abstract: Provided is a method and system for monitoring and analysis of networked systems, that is non-intrusive and real time. Both secure and non-secure traffic may be analyzed. The provided method involves non-intrusively copying data from a communication medium, reconstructing this data to a higher level of communication, such as the application level, grouping the data into sets, each set representing a session, and organizing the data for chosen sessions in hierarchical fashion which corresponds to the hierarchy of the communicated information. If monitored communications are encrypted, they are non-intrusively decrypted in real time. Hierarchically reconstructed session data is used by one or more plug-in applications, such as alarms, archival applications, visualization applications, script generation applications, abandonment monitoring applications, error detection applications, performance monitoring applications, and others.

Abstract: Disclosed are methods and threads for responding to a request to perform an operation on a server object as may be provided in software form within an object request broker (ORB) server library or an ORB server. The specified object is identified by a marshaled object key in a conventional manner. The method improves upon prior art techniques by directly locating the object using the marshaled object key free of any unmarshaling step. The specified operation can then be invoked on the located object. The method applies to both in-process and out-of-process requests. In a preferred implementation, the marshaled object key is utilized as a hash key to directly access a pointer to the object.
