Create a quota for
destinations in a system module
JMS quotas are used to
control the allotment of system resources available to destinations. For
example, you can specify the number of bytes or messages that a
destination is allowed to store, or specify whether the quota can be
shared be all destinations that refer to it.
To create a JMS quota:
If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).

In Policy, select the delivery policy
to determines whether to deliver smaller messages before larger
ones when a destination has exceeded its message quota. The FIFO
(first in, first out) policy strictly enqueues all send requests
for the same destination until there is enough space for the first
request in line. This prevents smaller messages from being
delivered when larger requests are already waiting for space. The
Preemptive policy does allow smaller send requests to preempt
previous larger ones when there is sufficient space for smaller
messages on the destination.
In Shared, specify whether this quota
is shared by destinations that refer to it.
Note: Once you create a quota, you cannot rename it.
Instead, you must delete it and create another one that uses the new
