A messaging system and associated computer program product. The messaging system includes a plurality of browsers connected through a common server. The server includes a message engine for receiving from a first user browser a request to enter chat mode with a second user browser; then receiving asynchronously from the second user browser a request to download any content from the common server or any other intranet or Internet server; and responding to the request from the second user browser with content modified to instantiate a chat session between the first and second user browsers.

System for messaging and collaborating in an intranet environment

A client-server application is provided to clients across a network. Requests from the client are accepted by a reliable proxy and sent to master and standby configurations of the client-server application. Each configuration processes the request to produce master and standby responses respectively. The proxy selects one response based on various criteria including a length being greater than the other response by more than a fixed value. The selected response is returned to the client over the internet. The configuration producing the selected response is thereafter designated as the master configuration. A recovery process may be initiated on the unselected configuration.

Quasi-high availability hosted applications

A method, system, and computer program product for processing a database query by a proxy server that is adapted to communicate with at least one database server. The database servers are respectively coupled to corresponding databases having tables that include a data isolation field pertaining to a group having subgroups. The data isolation field identifies a subgroup. The proxy server receives the query from an application server. The query is a request for data stored one of the databases. The proxy server determines whether the query has a data isolation problem. If the query does not have a data isolation problem, then the proxy server obtains a response to the query from one of the database servers and forwards the response to the application server. Otherwise, the proxy server records that a query error has occurred and returns an error code and/or empty dataset to the application server.

An apparatus for managing a cost of ownership of a portfolio of N software applications (N&#x2267;2). A regression function is identified for each application. Each regression function expresses an approximate cost of ownership of the applications in terms of parameters and coefficients. J applications A, A, . . . , Aare selected from the N applications such that a remaining N-J applications are unselected (J&#x3c;N). The coefficients for the N-J unselected applications constitute a subset of the coefficients for the J selected applications. Frepresents the approximate cost of ownership of the application Afor j=1, 2, . . . , J. An actual cost of ownership Gof application Afor j=1, 2, . . . , J is provided. The coefficients for the J selected applications are determined so as to minimize a function H=&#x3a3;W|F&#x2212;G|(P&#x3e;0). &#x3a3;represents a summation over j from j=1 to j=J. Ware predetermined weights.
