Abstract: A method and system for distributed garbage collection in a pipelined workflow environment comprising a plurality of processing nodes that pass item references to each other. Each node maintains a reference list of local item references and a reference dictionary of remote item references, and periodically synchronizes the reference list with the reference dictionaries of other nodes in the workflow, so that item references are not marked for garbage collection while other processing nodes may still have outstanding references to them.

Abstract: An interchange server for coupling with a plurality of connectors comprises an application collaboration module for defining the generic portion of the inter-operability function. The application collaboration module comprises a transaction service responsive to a trigger for initiating the inter-operability function and being activated upon receipt of data from one or more connectors. The trigger and the transaction deliver data to one or more connectors for transfer to an associated application whereby the inter-operability function is realized while each application is executing independently in an unmodified state. The connectors are configured for communicating with a like plurality of applications.

Abstract: A method, apparatus, article of manufacture, and memory for programmatically switching arbitrary HTML pages is disclosed. The method includes the steps of receiving control information in an application server from a client computer, and executing a script in the application server to generate a map relating HTML files with commands to show pages related to the HTML files. When a control event is received from the client computer, the mapping provides a basis for commanding the client computer's browser to switch to a second HTML page. In one embodiment, the invention also includes a program storage device, tangibly embodying instructions for performing the above method steps. The invention also includes an apparatus for remotely scripting local objects.

Abstract: A binary class library is adapted to provide full debugging type information particularly for use during program compilation in a minimal debug-generation mode. The library includes, a compile unit that #includes all the include files describing the classes that a given class library implements and exports. The compile unit also includes code defining a symbol with an external linkage. The resulting object module is put into the binary class library or a separate debug library. An inclusion direction and an external linkage symbol to the debug library are added to all include files for the class library that are #included by any program using its classes. These additions cause the compiler to direct the linker to add the debug library to the list of libraries from which it tries to resolve symbolic references, and to add a reference to the external linkage symbol that the linker will have to resolve by adding the debug library into the link.

Abstract: Automatic detection of the activities of a user of a data processing system is provided by the use of an Activity Event Detection Process, an Activity Detection Process, and an Interrogator Process. The Activity Event Detection Process detects events indicating user activity. The Activity Detection Process evaluates the user activity indicating events to determine the activity of a user. The Interrogator Process provides an interface to a requesting user and formulates appropriate queries to be sent to one or more Activity Detection Processes.
