摘要:
In a computer system where applications and data manipulated by the applications are implemented in an object oriented manner, an object type and its deriving attribute are stored as an entry in a table having an identifier. The object type table is in turn stored in a database. Similarly, the object type and its attribute values having corresponding attribute identifiers are stored as an entry in a table having an identifier. The object type attribute table is in turn also stored in a database. An object type deriving manager and an object type attribute values obtaining manager corresponding to the object type table and the object type attribute table are provided for deriving object type and obtaining object type attribute values respectively. A row getting interface routine and a column getting interface routine are provided for invoking the functions of the object type deriving manager and the functions of the object type attribute values obtaining manager. The object type is derived and the object type attribute values are obtained for an application upon receipt of the object type table identifier, the object type deriving attributes, the object type attribute table identifier, and the object type attribute identifiers from the application. As a result, applications are relieved of the burden of maintaining the necessary information for deriving object type and obtaining object type attribute values to improve interoperability between the applications.

A computer program product and apparatus builds a set of uninstall instructions from a set of installation instructions so that one or more installations of computer updates can be removed.

A method and apparatus for extensible inter-application link management is disclosed. The apparatus is independent of the applications that manipulates the anchors linked by the links being managed. Anchors linked may reside on the same or different computers on a network. Links managed comprise navigation links and include links. Links managed may be further extended with application defined links. Application defined links may or may not require support by additional application provided link maker programs. Application defined links may inherit linking operations managed from the navigation link, include link and other existing application defined links with or without override.

A method and apparatus identifies changes made to a computer system caused by the installation of software. The state of the computer system is recorded before the software is installed and, after the software is installed, the recorded state is compared against the state of the computer system. Changes are written into a manifest, which may be combined with any new or changed files and an installation program to produce a package which can be sent to another computer system for installation.

A method for enabling an application program to communicate with a network server, includes the steps of downloading a document from a document server to the application program, downloading code from a code server associated with the document server to the application program, the code including a network protocol handler for the network server, and using the network protocol handler to communicate with the network server.

摘要:
A method and apparatus checks a set of files against a manifest to determine whether to accept or reject the files. The manifest contains one or more policy sections that describe whether to accept files that are described in the manifest but not received, or received but not described in the manifest. The method and apparatus determines whether files are listed in the manifest but not received, or received but not listed in the manifest, and can accept the files in these circumstances based on the policy section of the manifest. The manifest may also contain a hash result for each file. The method and apparatus can hash the files received and compare the hash result produced with the hash result specified in the manifest. If the hash results computed for the file are different from the hash result for the file in the manifest, the file or the set of files may be rejected.
摘要:
A system and method for distributing software applications and data to many thousands of clients over a network. The applications are called “channels”, the server is called the “transmitter”, and the client is called the “tuner”. The use of channels is based on subscription. The end-user needs to subscribe to channel before it can be executed. When the end-user subscribes to a channel the associated code and data is downloaded to the local hard-disk, and once downloaded the channel can be executed many times without requiring further network access. Channels can be updated automatically at regular intervals by the tuner, and as a result the end-user is no longer required to manually install software updates, instead these software and data updates are automatically downloaded and installed in the background. This method of automatic downloading of updates achieves for the client the same result as the broadcast distribution of software over a connection based network, but wherein the client initiates each update request without requiring any special broadcast networking infra structure.

A system and method updates multiple servers automatically without taking all of the multiple servers off-line at the same time. The system and method selects a group of servers, takes the group off-line, updates the group taken off-line, and then brings on-line those members of the group that were on-line prior to the update and for which the update was installed successfully.
