ABSTRACT:
A common transactional logging system (a “virtual logging system”) that presents to one or more log clients the appearance that each log client is interacting with a dedicated logging system. In reality, the virtual logging system is multiplexing multiple virtual log streams, including log records, for each log client into a single transactional log.
