Oracle Error Message

ORA-29377: consumer group string is not part of top-plan string

Reason for the Error

OTHER_GROUPS was not included as part of the specified top-plan. Each top plan must include the built-in consumer group OTHER_GROUPS.

Solution

Create a plan directive with the argument GROUP_OR_SUBPLAN being OTHER_GROUPS somewhere in the top-plan.
