FCM parallelism support added

Fast communications manager (FCM) parallelism addresses potential scalability limitations in partitioned database environments.

Such limitations can occur when workloads drive the FCM engine component to capacity, resulting in queueing delays behind internode communications processing. You can enable this feature by using the fcm_parallelism database manager configuration parameter, which specifies the degree of parallelism that is used for communication (both control messages and data flow) between members within a DB2® instance.
