Cause: A prior error occurred on one of the instances in the cluster. Typically errors are caused by shared pool resource contention. See the solution below.

Error solution: Check for and resolve prior errors on all instances in the cluster. If there is shared pool resource contention, increase the SHARED_POOL_SIZE, DML_LOCKS, PROCESSES, TRANSACTIONS, CLUSTER_DATABASE_INSTANCES and PARALLEL_MAX_SERVERS initialization parameters.
