The statuses and callbacks are distributed evenly among the
connected clients. After a status or callback is received by a
client, that client is placed at the end of the receiving queue.
This method is used by distributed processing systems that want
to distribute the work among clients.
• First Received/First Scheduled
The statuses and callbacks are issued to the client that
successfully received the previous status or callback. The only
time a different client is tried is when the first client fails (at
which time the failed client is placed at the end of the queue).
The scheduling method selected by VolServ is dictated by the
ENTERPRISE_ROUND_SCHEDULING environmental
variable. If this variable is set to ‘Y’, the Round Robin
scheduling method is used. Otherwise, the First Received/First
Scheduled method is used. (The
ENTERPRISE_ROUND_SCHEDULING environmental
variable is in the envvar.config configuration file.)
