Does TimesTen support "Active-Active" replication --- where updates/writes can be done to more than one instance concurrently?

    Dear user6687665,

    Yes, TimesTen supports the "Active-Active" replication. All updates will be transferred between two instances but you should avoid a situation with updating the same row at the same time. Timesten also has a conflict detection mechanism.
    For more information please see the documentation (

    Best regards,

    If you are using TimesTen to cache Oracle database tables (via TimesTen Cache Group), the supported Replication configuration for HA is Active-Standby Pair with optional subscribers for readonly. In A/S Pair configuration, updates are allowed only on the Active and Standby can be used for reads.

    Can you expand on your use-case and what you meant by active-active? What are your high availability requirements?
