A system for aggregating user information on a plurality of projects and servers includes a project catalog; a project catalog server; a plurality of project servers; a plurality of project databases; a project database being associated with each project server; an entry in the project catalog for each project server and each project database; and a my projects procedure responsive to user entry of a my projects request for accessing the project catalog server to obtain markup language representations of entries in the project catalog for the user for display at a terminal.

System and method for aggregating user project information in a multi-server system

A server for executing operation calls by a client, including a dispatcher, a plurality of worker tasks, and a dispatcher shared memory area and worker control block for each worker task. Each operation call provided from a client is a sequence or one or more remote procedure call requests and each includes a packed buffer containing parameters. The dispatcher receives a buffer directly into the dispatcher shared memory space of the worker task selected to execute the remote procedure call request, sets the semaphore and sends a request acceptance response. The selected worker task unpacks the buffer into its memory space, executes the request, places the results into a packed buffer in its dispatcher shared memory area and sends a remote procedure call to the dispatcher. The dispatcher executes a remote procedure call to the client and sends the result buffer directly from the shared memory area. The server further includes a dispatcher state save mechanism and the remote procedure call from the worker task includes an identifier of the corresponding saved dispatcher state for the request. The packed buffer associated with a request includes client information and each worker task stores the client information in a worker shared memory space common to the worker tasks and each request of an operation call may be assigned to a different worker task.

Server for executing client operation calls, having a dispatcher, worker

A connection mechanism for providing connections between a client and a server including a connection control block for each connection, at least one client control block, and at least one session control block. Each connection control block identifies a connection and each client control block a client. Each session control block corresponds to a client control block establishes a session between a client and a connection and identifies the session, tile connection, and the server. Each session is established solely through a corresponding session control block and each operation is identified by the corresponding session identification. The connection mechanism includes a stack mechanism for storing at least one operation stack. Each operation stack corresponds to an operation to be executed through the corresponding connection and includes the session identifier and at least one operation request that is to be executed to execute the operation. An operation execution control generates a sequence of remote procedure call requests for each operation call and stores the sequence in a stack. Connection configurations may be specified. The system also includes a server and an authorization mechanism.
