Decision Service - Failure under stress

Question

After a recommendation from an Oracle consultant, we have decided to use the new Decision engine in 10.1.3.1 instead of using BPEL code to do some business rules.
So, we created a simple rule using the rules author and then deployed this onto WebDAV. We then added a decision service to call this rule, all good so far....
We then ran this from the BPEL Console, and it works fine.
However, when we place this under stress using the Stress Test tool it fails with about 2 requests in 5.
On disectiing the results from the BPEL audit, it looks to me as if the decision engine is single threaded, which is no use at all in our high throughput environment
My question is, has anyone actually deployed this experiencing the same issues?
The error we receive is :
<summary>exception on JaxRpc invoke:
start fault message:
Internal Server Error (Caught exception while handling request:
java.lang.NullPointerException)
:end fault message</summary>
Many thanks
Pete

Hi,
I am using oracle business rules with WEBDAV configuration for linux.
The rules are present in a linux box 10.1.3.3.0. (Box1)
The BPEL process with a decision service is deployed in another linux SOA Server 10.1.3.1.0 (Box2) and its conencting to the rule engine of Box1 using WEBDAV (not file based.)
Unlike file based there is not a local copy of repository file in j2ee/home/applications/rules_default_Invoke../
If any rule is changed in Box 1 the BPEL process in box 2 is not reflecting the change ,however if the BPEL process is redeployed the chanage is again visible.
Please let me know is there any configuration I need to change or is this a bug.
Note - As already mentioned the patch is present for 10.1.3.3.0 (i.e box 1) but still this bug is present.
Please let me know any pointers to proceed.
Best Regards
Ashif
