Mechanisms and techniques for database fragment cloning and management are provided. A database object, such as a table, rowset or index, is divided into fragments. Each fragment is cloned to create cloned fragments, which operationally are substantially identical to one another. One or more of the cloned fragments may be designated as a primary cloned fragment for performing database operations or as a secondary cloned fragment for serving as backup. Updates to each fragment are implemented on the primary cloned fragment and are then propagated from the primary cloned fragment to the corresponding secondary cloned fragments. A cloned fragment can go offline, becoming unavailable to be updated. When the cloned fragment returns online, the cloned fragment is refreshed with data included in the primary cloned fragment. While being refreshed, the cloned fragment may continue to be updated. The cloned fragment is eligible to be designated as a primary cloned fragment when the refreshing process has been completed.

Database fragment cloning and management

A virtual applications architecture is provided according to the present invention. The architecture includes a topology manager for managing applications across a plurality of members, and a virtual applications manager for defining a plurality of resources comprising the applications. The topology manager communicates with the plurality of members to initiate scaling of the applications associated with the virtual applications manager to the members. The architecture may also include a replication system for deploying the applications to the members.

System and method providing virtual applications architecture

An information server adapted to service requests for information has an integral database containing configuration information, application information, and/or content information. The information in the database is stored in a hierarchical fashion with elements that correspond, in some degree, with physical storage structure or individual information objects on the information server. Path names received in information requests are broken into constituent components and are used to retrieve configuration information, application information, and/or content information from the database and information objects from physical storage. In the database properties stored at one hierarchical level may be inherited by lower hierarchical levels. The database is preferably provided with a programmatic interface that allows concurrent access to and administration of the database. Mechanisms to notify registered users of changes or events that occur with respect to the database are implemented.

System and method for administering a meta database as an integral

A method for tracking usage patterns of users of hyper-media systems, such as the World-Wide Web, that creates a usage log on a user's client computer and periodically transmits the usage log from the user's client machine to a usage tracking server computer to be incorporated in an overall usage log for a given information server computer. Alternatively, proxy server may be connected between a client computer and an information server with the proxy server acting as a client to the information server and creating a usage log of the user's client computer access to the information server computer to be sent to usage tracking computer. Each time a user connects to a Web site, the client computer or proxy server creates a usage log that records all objects retrieved from that particular Web site and other attributes of user processing such as time spent viewing an object, amount of an object viewed, etc. Periodically, upon the occurrence of one of more predefined events that signify the end of a session, computer or proxy server saves the usage log into a single, compressed file and transmits the resulting file to the server. Events that signify the end of a session and trigger the transmission of a usage log from the user's client computer or proxy server computer to the usage tracking server computer may include a predetermined time interval, accessing a predetermined number of objects, application program or operating system shut down, connecting to a different Web site, and/or modem shut down.

Method, system and apparatus for client-side usage tracking of

An access-check system for a network server comprises an access-cache for storing access-permissions generated by the server in response to resource access requests. The system retrieves the appropriate access-permission from the access-cache in response to receipt of a request necessitating the same access-permission as already generated for an earlier processed request. A user-token cache is also employed to assign a unique user-token, to be used in the access-cache, to each user logged on to the server. Changes made to the user-token cache are reflected in the access-cache by removing from the access-cache those entries containing the changed user-token. Changes made to an access control list are reflected in the access-cache by removing from the access-cache those entries containing the server resource with which the changed access control list is associated.
