Oracle : Ошибка ORA-29706

"incorrect value %s for parameter ACTIVE_INSTANCE_COUNT"
*Cause: The ACTIVE_INSTANCE_COUNT parameter must be set to 1 in a two
node cluster database configuration or unspecified if a secondary
instance is not needed.
*Action: Check your initialization parameter files and correct the value
of the ACTIVE_INSTANCE_COUNT parameter. If you are configuring a
two node primary/secondary cluster database, set this value to 1.
Otherwise, do not specify any value for the parameter.
