One way child BPEL getting rolled back 11g

Question

Hi,
I am stuck with a strange issue.
Here is my design :
Bpel1
1. Invoke : Call One way Bpel2 -> Bpel 2 calls DB adapter to insert data to Database
2. Throw rollback
When i throw rollback in BPEL 1 both : BPEL 1 & BPEL 2 gets rolled back , I need BPEL 2 to get commit to DB.
I tried below settings :
BPEL 1 : weblogic.wsee.wsat.transaction.flowOption = NEVER for calling BPEL 2
BPEL 1 : bpel.config.onewayDeliveryPolicy = async.persist
BPEL 2 : Service end point weblogic.wsee.wsat.transaction.flowOption = NEVER
BPEL 2 : bpel.config.transaction = requiresNew
BPEL 2: bpel.config.onewayDeliveryPolicy = async.persist
These settings didnt helped , please suggest.
Thanks
Sam

Hello Sam,
I have created two one-way BPEL Processes with the same settings you have mentioned. In order for the DB insert in the second BPEL to be saved, you need to add one additional property.
In BPEL1, for the partnerlink of BPEL2, add the property called 'idempotent' and give its value as false.
And now test the process again, this time, after calling the BPEL2 from BPEL1, you will be throwing a rollback fault, but the record which is inserted through BPEL2 will be there in the database which is what you want.
Here the idempotent property saves the current transaction after calling the BPEL2, and starts a new transaction.
Hope this helps,
