A data processing system having the capability to store data is provided with a facility to dynamically establish a data pipeline extending from a source of the data to an intended recipient. The operation of the data pipeline facility is typically initiated in response to a user entering a request for particular data. Specifically, upon receipt of the user request, a chain of commands is dynamically constructed, in which each command is operative for forming a respective leg of the data pipeline and for invoking the next, adjacent command in the chain. In the instance where the desired data comprises a plurality of fragments, the commands then maintain the pipeline until the last of such fragments has been obtained from the source. Thereafter, each command terminates its respective leg of the pipeline after passing the last fragment of data to the next command in the chain.
A Client/Server Database System with improved methods for performing database queries, particularly DSS-type queries, is described. The system includes one or more Clients (e.g., Terminals or PCs) connected via a Network to a Server. In general operation, Clients store data in and retrieve data from one or more database tables resident on the Server by submitting SQL commands, some of which specify "queries"--criteria for selecting particular records of a table. The system implements a "Data Pipeline" feature for programming replication of data from one database to another in client applications. Specifically, a pipeline object and SQL SELECT statement are built using a Pipeline Painter. The Data Pipeline lets a user (developer) easily move data from a high-end database server (e.g., Sybase) to a local database (Watcom SQL), all without the user having to issue SQL commands. The pipeline object facilitates moving data from one database management system to another, or between databases of the same type.
A system and method for pipelined data processing emulates multi-tasking pipelined data processing in a single tasking environment. A host application running in the single tasking environment creates a pipeline of linked data processing tasks to process data from a data source and to provide the processed data to the host application. As each data processing task of the pipeline is created, the task calls an external procedure to obtain header data indicative of the data to be received by the task. Each task alters the obtained header data to reflect the data processing operation to be performed by the task, then the task creates an external procedure callable by other tasks or the host application. The external procedure provides the processed header data from within a task to the calling task or host application. After all tasks of the pipeline are created the host application invokes the pipeline to obtain processed data from the pipeline.
The present invention relates to a process for assisting in the administration of a distributed application of a transaction processing manager based on a binary configuration file (TUXCONFIG), characterized in that said process comprises: decompiling the active configuration file of the master machine (Mm), retrieving information from the decompiled configuration file of the master machine, and checking the consistency of said application running on said given machine. Information related to at least one listener module is displayed and includes at least the name of the application, the logical name of the machine (LMID) on which the application is run, the identification of the user (UID) of said application, the address used by the listener module (NLSADDR), the access path to the network of the application, and the access path to a log file of said listener module (LLFPN). If the tlog file containing information on the application running on a given machine does not exist, the file is automatically generated in order to be able to used the file during the next startup of the listener modules.
The present invention is a network operation center which centrally connects multiple external computer systems belonging to automobile dealers, manufacturers, and vendors of goods and services. The network operation center provides centralized network security, allowing the dealers, manufacturers, and vendors to access certain portions of each other's data while protecting other data. It further provides data translation so that incompatible data formats and structures may be shared. Dealers communicate through the network operation center with multiple manufacturers and vendors with a single network connection, reducing the need for multiple individual connections to each manufacturer. Network support and updating of system hardware and software is centrally performed. Dealers lease access to a network operation center and accompanying data connections, along with technical support, hardware, and software from a single service provider. Alternatively, a single service provider independent of a network operation center may provide the data connections, hardware, software, and support.
A system, method and computer program product are provided for programmable processing of fragment data in a computer hardware graphics pipeline. Initially, fragment data is received in a hardware graphics pipeline. It is then determined whether the hardware graphics pipeline is operating in a programmable mode. If it is determined that the hardware graphics pipeline is operating in the programmable mode, programmable operations are performed on the fragment data in order to generate output. The programmable operations are performed in a manner/sequence specified in a graphics application program interface. If it is determined that the hardware graphics pipeline is not operating in the programmable mode, standard graphics application program interface (API) operations are performed on the fragment data in order to generate output.
