To restart the sequence at a different number, specify RESTART with the START WITH clause to set the value at which the sequence restarts. If you alter the sequence by specifying the KEEP or NOKEEP clause between runtime and failover of a request, then the original value of NEXTVAL is not retained during replay for Application Continuity for I need to migrate an existing Oracle Database into a Derby one.
