Performance Tuning Siebel Software on the Sun Platform

7.2.3 Assignment Manager <strong>Tuning</strong>
The <strong>Siebel</strong> 7 Assignment Manager (AM) processed assignment transactions for sales
opportunities based on employee positions and territories. AM was run in batch
assignment mode.
For this component the main tunable is the requests parameter.
Tuneable parameter: Requests
Default value: 5000
Value used in benchmark: 20
Description
Maximum number of requests read per iteration. This controls the maximum number of
requests WorkMon reads from the requests queue within one iteration.
It did not help to change deletesize to 400 (from default of 500) or to add indexes to
the table S_ESCL_REQ .
After reducing the number of requests per iteration from 5000 (default value) to 20 for
component WorkMon, CPU utilization was reduced from 72% to 53% on the <strong>Siebel</strong>
server node where AM and EAI-MQ tests were run together.
