You get this message if SMON failed to generate the slave servers
necessary to perform a parallel rollback of a transaction.
Check the value for the parameter, FAST_START_PARALLEL_ROLLBACK
(default is LOW). LOW limits the number of rollback processes to 2 *
CPU_COUNT.
HIGH limits the number of rollback processes to 4 * CPU_COUNT.
You may want to set the value of this parameter to FALSE.
