Abstract: A technique allows dynamic negotiation of application names executing on nodes of a computer network for creating a data link for communication between the nodes. Dynamic negotiation is effected through an exchange of novel control messages over a control link used to establish application-application logical links between the nodes. The control messages instruct the nodes to create applications having names specified within predetermined fields of the messages. The technique obviates the need for a system administrator to issue configuration commands to a responding node to statically configure that latter node for communication over a network.

Abstract: In a computer system having a kernel supporting an interface definition language, a file system composed of an object framework. The object framework includes a set of proxy vnodes, a set of memcache vnodes, and a set of storage vnodes. The set of proxy vnodes and the set of memcache vnodes are linked to the set of storage vnodes through the use of the interface definition language, and the set of proxy vnodes are linked to the set of memcache vnodes through the use of a set of pointers. Each proxy vnode of said set of proxy vnodes is typed so as to differentiate between a set of file system objects such as files, directories and devices. The set of memcache vnodes forms an interface to a virtual memory system while the set of storage vnodes forms an interface to an underlying file system. The file system also uses a set of file paging interfaces that support extensions to the file system while providing full coherence of data.

The dynamic link library module includes a dispatching function adapted to recognize the unique identification each of the desired functions and export the desired function for execution by the program. There is also provided a look-up table for the executable program having therein a listing for each of the desired functions and unique identifications. The process includes loading the dynamic link library module with the program and calling the desired function by passing the desired function identification from the program to the dispatching function. Thereafter, the desired function is exported from the dynamic link library module to the program.

Abstract: Systems and methods for providing communication between different implementations of object request brokers are provided. A bridge including a proxy object allows communication between the object request brokers. The proxy object within the bridge stores the server object reference in its reference data. The proxy object translates messages (e.g., requests and responses/exceptions) to the transfer protocol of the server object and redirects these messages according to the server object reference stored in the proxy object's reference data.

Abstract: An interprise computing manager in which an application is composed of a client (front end) program which communicates utilizing a network with a server (back end) program. The client and server programs are loosely coupled and exchange information using the network. The client program is composed of a User Interface (UI) and an object-oriented framework (Presentation Engine (PE) framework). The UI exchanges data messages with the framework. The framework is designed to handle two types of messages: (1) from the UI, and (2) from the server (back end) program via the network. The framework includes a component, the mediator which manages messages coming into and going out of the framework. A distributed computer system is presented with software for a client computer, a server computer and a network for connecting the client computer to the server computer which utilizes an execution framework code segment configured to couple the server computer and the client computer via the network.

Abstract: An object-oriented interprise computing manager provides coordination between application programs by having each server program controlling the client executable program. In this manner, each client program communicates from the client to the server using a predefined protocol.

Abstract: A method for calling and executing a program is disclosed. A command having zero or sequentially independent parameters values is received. The command corresponds to a program with a number of recognized parameters equal to or greater than the number of parameter values in the command. The parameter values are parsed based at least in part on demarcations in the command. The parameter values are associated with the corresponding parameters recognized by the program. Any parameter which did not have corresponding parameter values are set to default values. The program is executed to perform one or more tasks using the parameter values and the default values.

Abstract: A method, apparatus, and article of manufacture for a software interface for dynamic API mapping. The method comprises the steps of identifying the libraries required by the API by determining which program environment the API is operating in, scanning to detect and select libraries available to the determined program environment, dynamically loading the selected libraries, dynamically loading the selected libraries into the application, and binding the selected libraries to the associated API function call. The present invention allows a single binary application to transparently work with different libraries that provide a common or overlapping API set. This is accomplished by linking the application with a separate library that provides a dynamic API mapping facility. A function in this library is invoked when the application begins execution. The application's system is scanned to determine which libraries are available.

Abstract: A data processing system and method of task management within a self-managing application program including a number of tasks and a processing time monitor are disclosed. In accordance with the present invention, a selected portion of processing time is allocated to each of the tasks in the self-managing application and the tasks are executed by the data processing system. Utilizing the processing time monitor, a determination is periodically made whether an actual portion of processing time utilized by each of the tasks exceeds the selected portion of processing time allocated to that task. In response to a determination that an actual portion of processing time utilized by a particular task exceeds the selected portion of processing time allocated that task, execution of the particular task is suspended for a selected penalty time.

Abstract: A method and system for preventing incorrect information from corrupting server object information maintained by a client machine. A DCOM client machine is provided with object reference information for accessing remote objects. DCOM unmarshals the information into server object information, including an object identifier and string bindings of a remote resolver through which the client machine may contact the remote server to obtain string bindings for that remote object. Each resolver string bindings received by a client machine are compared against known resolver string bindings and each unique permutation of string bindings is associated with a unique machine identifier locally generated therefor. Each object identifier is paired with its corresponding unique machine identifier so that all references to a remote object include the identity of the machine on which the object was created.
