The process control system features an interactive optimization modeling system for determining manipulated process variables (also known as setpoints). These manipulated process variables are used to position mechanisms which control attributes of a manufacturing system, such as a valve controlling the temperature of a coolant or a valve controlling the flow rate in a steam line.

Mechanisms and techniques provide a system that provides stream data to a client by monitoring operation of a stream control protocol such as RTSP associated with stream data transmitted between a client and a first stream server. The system detects a stream change event related to transmission of the stream data between the client and the first stream server and identifies a relative position within the stream data based on the operation of the stream control protocol. The system then establishes transmission of the stream data between the client and a second stream server starting at the relative position in the stream data. The system provides for mid-stream failover for the transmission of stream data such as real-time data with minimal perceptible loss of stream data by the client.

The data migration program includes a volume module to control the volumes during the migration session. The data migration program includes a copy module to control the copying of data from the source module to the target module during the migration session. The data migration program includes a monitor module for monitoring I/O transfers to the data volumes during the migration sessions. The computer system may have a plurality of operating systems associated with instances of the data migration program which allows for concurrent data migrations. The plurality of instances of the data migration program may also be controlled in a master slave relationship. A migration session may include a plurality of migration phases such as activation, copy, refresh, quiesce, synchronize, redirect, resume and termination phases.

Indirect access to local file systems is provided using storage tank protocols, allowing federation of a local file system into a distributed file system while preserving local access to the existing data in the local file system. The goal of the present system is to federate and migrate the data on a computer system with minimum disruption to applications operating on the computer system. Existing applications on a computer system continue to operate during data federation and migration and require little or no reconfiguration either when the data migration starts or when it ends. Data consistency is maintained: existing applications may modify data in the file system during migration or federation. During federation, other computer systems (or hosts) may modify the data in the file system if access control information allows them to do so. All changes in the file system are seen consistently on all hosts. Minimal downtime is required to install the present system and reconfigure the existing applications to communicate with the present system.
