Abstract

A method and apparatus are provided for storing transaction data for a plurality of database applications in a multiple access database management system having permanent storage and a transaction log buffer to store data for said database applications before transferring said data to said permanent storage, wherein database connection agents associated with said applications are used to store data in said transaction log buffer, includin g granting exclusive write access reservations in said transaction log buffer to a plurality of said database connection agents; and allowing database connection agents to write transaction data records to previously granted write access reservations while granting exclusive access reservatio ns to other database connection agents.
