Latest Patents

Atsushi Morimura holds 1 patent for his invention titled "Failover and resume when using ordered sequences in a multi-instance database environment." This patent discloses a method for implementing failover and resume processes when utilizing ordered sequences across multiple database instances. The approach begins with the instantiation of a primary database instance as the active instance, while secondary instances are set up as passive. The active instance manages mastership over a sequence and processes requests for the next symbol by accessing a shared sequence cache after engaging a first instance semaphore. In the event of a failure of the active database, one of the passive instances takes over mastership, ensuring that the order of sequence values is maintained despite the failure.
