You can avoid such a scenario by limiting the number of parallel servers that can be used by a particular consumer group. Use the PARALLEL _TARGET _PERCENTAGE directive attribute to specify the maximum percentage of the parallel server pool that a particular consumer group can use.

Management attributes also enable you to specify CPU resource allocation for Exadata I/O. This consumer group can use a maximum of 50 of 32, or 16 parallel servers. If your resource plan has management attributes (MGMT _P1, MGMT _P2, and so on then a separate parallel statement queue is managed as a First In First Out (FIFO ) queue.
