A distributed redundant database architecture (10) primarily for storing a plurality of wireless service subscriber files (84, 86) is provided. The database architecture (10) include a first set of processors (44 46, 48) each having a shared memory (72, 74, 76), where the processors (44, 46, 48) are divided into processor groups (38, 40, 42). A memory storage device (80, 82) is coupled to each processor group (38, 40, 42) in a multi-initiator mode so that each memory storage device (80, 82) is accessible by the processors (44, 46, 48) in its respective processor group (38, 40, 42). The plurality of subscriber files (84, 86) are assigned to the processor groups (38, 40, 42) and further assigned to the processors (44, 46, 48) in each processor group (38, 40, 42) to achieve a substantially even distribution. The plurality of subscriber files are stored in the memory storage devices (80, 82) of respective assigned processor groups (38, 40, 42), and are mapped into the respective shared memories (72, 74, 76) of the processors. A database manager (52, 54, 66) associated with the processors and processor groups is provided for managing the distribution and redistribution of the subscriber files to the processors. A second set of similarly configured processors residing at a remote site (14) maintains a second copy of the subscriber files (84, 86) to provide database backup.
