Jeff,
So far, for Client A, we've only had to update a single BPEL timeout value, which is the "transaction-config timeout" specified in the server.xml file. We set the value as follows:
server.xml Code:
<transaction-config timeout="300000" />
For Client B, we had to change a two, as follows:
server.xml Code:
<transaction-config timeout="300000" />
domain.xml Code:
<property id="syncMaxWaitTime">
<name>Delivery result receiver maximum wait time</name>
<value>120</value>
We also had to increase the Java Heap (memory allocation) of the BPEL server to get it to process more efficiently and reduce transaction times. The minimum heap I would consider for your BPEL server is 1024MB.
Haven't had to adjust any of the other files that you referenced, but these may be due to the version of BPEL that you are using?
Thanks,
Chris
