  • Local logging in a distributed database management computer system
    Patent number: 5966706
    Abstract: A distributed database management computer system includes a plurality of nodes and a plurality of database pages. When a first node in the computer system updates a first database page, the first node generates a log record. The first node determines whether it manages the first database page. If the first node determines that it manages the first database page, the first node writes the log record to a log storage local to the first node. However, if the first node determines that it does not manage the first database page, the first node then determines whether it includes a local log storage. If the first node includes a local log storage, the first node writes the log record to the local log storage, even if the first node does not manage the first database page. If the first node does not include a local log storage, the first node sends the log record to a second node managing the first database page.
