A base multiport node class is provided, which is configured to provide a multiport node for each operator object. The multiport nodes instantiates a pluggable operator for connecting the multiport nodes together at runtime according to user-defined parameters. The connection of multiport nodes implements the processing functions of the operator objects to execute the application.

Abstract: A computing system for performing stateful distributed computing includes a client machine having a Client Runtime Environment (CRE) that is adapted to maintain the state of an application in the client machine. The CRE maintains state of the application by first retrieving a first markup document of the application, creating and storing a first object oriented representation of information contained in the first markup document. The first object oriented representation defines a first state of the application. Next, retrieving a second markup document, creating and storing a second object oriented representation of information contained in the second markup document. Finally merging the first and second object oriented representations thereby forming a new object oriented representation of information contained in the first or the second markup documents. This new object oriented representation defines a new state of said application.

Abstract: A method and system for responding to requests for static web documents including saving the response as a packet train comprising one or more IP compliant packets. Upon a subsequent request for the static web document, the saved packet train may be retrieved and the header information updated. In this manner, the network protocol processing required to respond to the request is reduced. The server may include code for determining whether a referenced web object is a static object and a directory of recently accessed static web objects and a copy of the corresponding packet trains. The web server may be configured to consult the directory to determine if an object is a static object that has been recently accessed. If the object has been recently accessed, the server may retrieve the corresponding packet train from its system memory or from disk and update the packet headers prior to transmission.

Abstract: A method of bulk import in a directory server, including defining an extended operation on a server and a client, sending an extended operation request from the client to the server, performing the extended operation after receiving the extended operation request from the server, sending a response of the server back to the client specifying an object identifier of the extended operation and data specific to the extended operation; and performing a series of LDAP add operations framed by extended operations to import an entry into the directory server. A bulk import system for a directory server, including a processor, a memory, extended operations defined on a server and a client, and software instructions residing in memory executable on the processor for performing a series of LDAP add operations framed by extended operations to import an entry into the directory server.

Abstract: A method, apparatus and program storage device for enabling the reading of data from a named pipe by a reader process while minimizing the use of system resources in an information handling system in which client and reader processes write data to and read data from a named pipe by issuing function calls to an operating system. A first reader process creates a named pipe if it does not already exist and issues a read function call to the operating system specifying the named pipe to attempt to read data from the pipe. If the read operation is successful, the first reader process repeats the step of issuing the read function call. Otherwise, the first reader process issues an activate-on-receipt function call to the operating system, specifying the named pipe, a new reader process to be activated upon the receipt of data by the named pipe and, optionally, data being passed from the first reader process to the new reader process, and then terminates.

Abstract: An annotation source representation is supported by a compiler and/or linker to annotate program code, so that analysis tools, such as debuggers and profilers, have more information with which to analyze an executable program. The annotation source representation in the source code is compiled into annotation information so that the annotation remains in the executable code, but is not executed. The annotation information in the executable program is associated with the code that the annotation function is associated with. The present invention eliminates the need of parallel/companion input command files, eliminates the need of compiling a special version of the executable program for purposes of analysis, and eliminates the need of implementing debug statements in the source code.

Abstract: A method and apparatus that includes processing for providing reliable interoperation of the plurality of independent software modules. Such processing begins by determining selection of an object by one of a plurality of independent software modules to produce a new object selection. The processing then continues by determining object selection status, which indicates a selected object and an associated one of the plurality of independent software modules. In other words, the object selection status indicates which independent software module is currently managing a particular object. The processing then continues by updating the object selection status when a difference occurs between at least one of the independent software modules identified currently in the object selection status and the independent software module selecting the object, and/or the newly selected object is different from the object identified in the object selection status.

Abstract: A data processing system and method manage the storage of instructions used in applications developed using an interpretive programming language, such as Java, REXX, BASIC, and the like, when those instructions are compiled into byte-codes to be used by a virtual machine stored in a “heap.” In the data processing system and method, an exception is registered in a page manager of an operating system to identify that compiled code should be stored within the heap of the virtual machine. After that code has been compiled and deleted from the heap, an exception occurs when the virtual machine attempts to subsequently access the compiled code. At that point, the virtual machine is then enabled to retrieve the desired code from an interpreted programming language application.

Abstract: An apparatus and method for performing workload management is provided. In particular, an apparatus and method for performing workload management using class shares and tiers is provided. In the apparatus and method, each process is associated with a particular class of workload. Each class has an associated number of shares representing the importance of the class relative to other classes. Each class, in turn, is associated with a particular tier of workload importance. Classes of processes compete with other classes of processes in their same tier for system resources based on the number of shares that they have. These shares are representative of the percentage of the system resource the process is provided relative to the other classes in the same tier. Classes in one tier compete with classes in other tiers for system resources based on the priority assigned to the tiers.

Abstract: As a solution to the problem of distributed knowledge of data object definitions, data object definitions are removed from the source code. A Meta Data Service is created and made available on a network which knows the definitions of all of the objects that are used by applications that are designed to use the Meta Data Service. When an object is created, the Meta Data Service creates and stores a meta definition for the object. Data objects are passed over a network in a “soft” format. Applications within a distributed data processing system are designed in such a manner such that, at any stage of object processing, an application does not assume to understand the definition or structure of an object, nor is an application hard-coded with the object definitions. At each stage, an application queries the Meta Data Service for the meta definition of the object before proceeding with the processing of an object.

Abstract: A method and computer program product is shown for use with a computer programming language having dynamic types and overloaded functions. A function data structure (a function handle) is constructed using a function name, which data structure contains or leads to information necessary to resolve function overloading, and also may lead to other auxiliary functions such as write, read or print. Application of the function data structure at the point of construction is functionally equivalent to application of a function name string. However, the function data structure may be applied without regard to the scope at the point of construction.
