In a network computing environment with a distributed software system utilizing Common Object Request Broker Architecture (CORBA), a Universal Client and Consumer tool that creates Client and Consumer implementations for use in interacting with any existing Servers and / or Suppliers in the system, and displaying the data resulting from the interactions for the purpose of validating the operation, functionality and performance of the Servers and Suppliers. The tool creates a graphical user interface for the user to select Servers or Suppliers to evaluate. The tool identifies the Server or Supplier IDL interface, and then creates either a Client or Consumer Implementation that uses the same corresponding IDL interface. The tool then attempts to connect to the Server or Supplier and where appropriate allow the user to invoke methods. Data received from the Servers and / or Suppliers is displayed on a video device and logged for later analysis.

A data management system stores and visualizes data generated during process management. The data management system provides different data management services and definitions of these are stored in a database.

Methods and apparatus, including computer program products, for communications in a distributed software system. An operation request from a remote computer is received, and provisionally executes an operation identified by the operation request. A first message is generated. The first message contains a transaction identifier identifying the operation request, an unsuccessful indicator flag, and a temporary data store. The temporary data store identifies tentatively written data generated by the operation. The first message is stored in a message store.

A new method is disclosed, for upgrading the software in a real-time distributed software system comprising several processes running in parallell. The method involves a preparatory procedure in which the new software is installed. Then, the software is activated, the components ordered to save configuration data and transaction data in a database, whereupon the components are stopped. When the preparatory procedure is completed, a restart procedure is invoked. This involves selecting start level (full upgrade involving all components, or a partial upgrade concerning just one or a few components). The modules concerned are started from the new software version. On each start level a number of start phases are defined. These are sequential steps performed during the restart operation. Each module subscribes to a number of these phases. Some of the phases are defined as synchronisation points, here called service levels, which all modules have to arrive at before the process is allowed to commence. During this process, each module is given the responsibility of converting any configuration data or transaction data belonging to it, if needed. The conversion is done by reading the old data from the database mentioned above and converting said data to the format required by the new software.

The invention discloses a method of disposing a Distributed Software System to solve problems, in the prior art, of software version inconsistency which is caused by large quantity of distribution spots of service, difficulty in disposing service software and easily caused inappropriate human operations.

(2) the local proxy process updates the software version according to the instruction, in which the center service process and the local proxy process will use uniform binary instruction. Therefore, all the local proxy processes on each service distribution spot will update the version of the service software from the center service process, which enables the service software of each service distribution spot of the enterprise-level or telecommunication-level software system to keep consistent with each other, thereby avoiding the inconsistency of service software caused by large amount of inappropriate human operations, and making the distribution of the service software easier.
