It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractA method, system, and computer program product for transmitting a redo stream from a database to one or more distributed database systems, upon which applications that process the redo stream are implemented, and which maintains the data dictionaries by replicating the multiple versions of the schema objects to data dictionaries in the distributed database systems. A method of maintaining a multi-version data dictionary includes generating a logical redo stream, inserting procedure calls to be used to populate the multi-version data dictionary into the generated logical redo stream, transmitting the logical redo stream to the multi-version data dictionary, and executing the procedure calls at the multi-version data dictionary to populate the multi-version data dictionary.Other References
