Appendix A - performance considerations
This appendix contains information to assist you in achieving the best performance
for your specific environment.
Managing queue overflow
WebSphere Partner Gateway components use a JMS queue to asynchronously
invoke each other. However, if the arrival rate of messages in a queue is greater
than the processing rate of those messages, the queue will reach its maximum
number of messages. If depth of the queue becomes equal to the maximum depth
configured for that queue, the queue overflows. WebSphere Partner Gateway
provides a mechanism of persisting the incoming documents or messages to the
file system in a queue overflow situation.
Note: The maximum depth of queue might be reached during peak loads or while
processing large documents. Monitor the queues during these times to ensure that
the queue depth is large enough so that it does not overflow.
See “Appendix C - component-specific system attributes” on page 223 for the list
of attributes used to manage queue overflow.
Generating summary data
About this task
WebSphere Partner Gateway periodically summarizes data about system activity.
This Summary Service data is the information you see when you use the
Document Analysis or Document Volume Report functions.
You can view and edit how often the summary data is generated with the
Summary Service Properties window. This window also displays the date and time
that the summary data was last updated.
To change the time interval that summary data is generated:
1. Click System Administration > Event Processing > Summary Service . The
Console displays the Summary Service Properties window.
2.
Click the Edit icon next to Processing Interval (in Minutes) .
3. Type a value (from
1
through
60
) indicating the number of minutes that should
occur before data is summarized again. The default value is
15
.
4. Click Save .
