Wait times for FCM communications
In a multi-partition database, or
in an environment where there is intrapartition parallelism, the Fast
Communications Manager (FCM) manages communication between different
agents working on the same statement, whether those agents are on
the same or on different members.
All
FCM communications involve the potential for wait times as one agent
waits for work to be done by another, or for data to transferred from
one to another.
