Abstract: The system for simulating user activity on a multi-tier computer network includes an event capture database for capturing interface level information and kernel level information associated with the interface level information. A virtual script editor module creates a virtual script from the captured interface level information and captured kernel level information to simulate user activity on the network. A virtual script playback module is responsive to the virtual script to produce virtual kernel level information indicative of network and server activity associated with a virtual user.

Abstract: The application package building system includes an application storage maintaining specification and component information, and a client package build system which creates an application package definition for both a client application package and a server application package. The package definition identifies required specification and component information for both the client application package and the server application package. A client package build engine builds the client application package using the required specification and component information, and a server package build engine builds the server application package from the required specification and component information.

Abstract: A computing system according to the present invention includes data having a primary access location in the system and having a secondary access location in the system. The system also includes a computer running an application, where the application requests for the data having the primary and secondary access locations. In response to the application requesting the data, middleware on the computer determines whether the requested data is at the primary access location. If the data is at the primary access location, the middleware retrieves the requested data from the primary access location and sends the requested data to the application. In response to the data not being found at the primary access location, the middleware retrieves the data from the secondary access location. The middleware then sends the requested data to the application and stores a copy of the requested data at the primary access location. The middleware is implemented as software.

Abstract: A computer system includes at least one client computer and at least one server computer. An Object Configuration Manager allows a user to distribute and use objects, such as business logic, database tables, and batch applications. Additionally, through the Object Configuration Manager, access to objects can be limited to select users and applications. The Object Configuration Manager is implemented as a software application.

Abstract: A data processing system for computer application installation on a client/server network on an as needed basis is disclosed. The server computer includes an installation unit, a system application repository, and a user information file. The client computer includes a menu driver, an application check unit, a local application repository, and a local version repository. A user on the client computer selects an application to execute through the menu driver. The application check unit searches the local application repository and the local version repository for the application and, if found, determines whether it is the most current version unless the most current version is already installed on the client computer. After installation is completed on the client computer, the application is automatically executed. Further, the present invention includes a method for installing a computer applications and/or update on an as needed basis.

Abstract: In a computer network comprised of multiple nodes spread across different geographic locations and connected through a communication system, a Distributed Data Synchronizer (DDS) synchronizes files across the network so that user applications running at the various nodes can share common databases of information. In a preferred embodiment, rather than store master files at a server node, each node stores a master copy locally in a disk drive. When a user application modifies one of the local files, the DDS communicates the update to the appropriate remote nodes under the control of a user defined script file.
