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 Messages Maximum, enter the total

In Policy, select the delivery policy
to determine whether to allow smaller message send requests to be
satisfied before larger ones when a destination has exceeded its
message quota. The default FIFO (first in, first out) policy
blocks subsequent newer sender requests until there is enough
space for the first request in line, or denies the newer requests
with a quota exception if the newer requests time out. The
Preemptive policy allows newer smaller send requests to preempt
previous larger requests when there is sufficient space for
smaller messages on the destination, but not sufficient space for
the older larger requests.
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
