Oracle BPEL Transaction Attribute

Question

Hello,
We have a scenario to handle Transactions using three parallel sequences those invoke stored procedures. The stored procedure would return success/failure on the out parameter.
Based on the failure (out parameter), we would like to do a rollback all the stored procedures inserts/updates. In my scenario, the 3rd procedure would send failure.
I tried using participate attribute as follows,
<?xml version = '1.0' encoding = 'UTF-8'?>
<BPELSuitcase>
<BPELProcess id="ParalleFlow" src="ParalleFlow.bpel">
<partnerLinkBindings>
<partnerLinkBinding name="client">
<property name="wsdlLocation">ParalleFlow.wsdl</property>
<property name="transaction">participate</property>
</partnerLinkBinding>
<partnerLinkBinding name="Temp1DB">
<property name="wsdlLocation">Temp1DB.wsdl</property>
<property name="retryInterval">60</property>
<property name="transaction">participate</property>
</partnerLinkBinding>
<partnerLinkBinding name="Temp2DB">
<property name="wsdlLocation">Temp2DB.wsdl</property>
<property name="retryInterval">60</property>
<property name="transaction">participate</property>
</partnerLinkBinding>
<partnerLinkBinding name="Temp3DB">
<property name="wsdlLocation">Temp3DB.wsdl</property>
<property name="retryInterval">60</property>
<property name="transaction">participate</property>
</partnerLinkBinding>
</partnerLinkBindings>
<configurations>
<property name="transaction" encryption="plaintext">participate</property>
</configurations>
</BPELProcess>
</BPELSuitcase>
But I have observed that inserts/updates have happened in the first and second tables.
Note: 1 )Stored procedure do not have any commit statement.
2) Each stored procedure is called by DB adapter (separately).
3) Each sequence has a throw logic with BPELX:rollback on the condition of failure from stored procedure.
4) All the three sequences have been enclosed in a single scope that has a catchall block that throws the BPELX:rollback as well.
Thanks

Hi,
I'm trying to employ the transaction property like this but it's not working:
<partnerLinkBinding name="GetPartyID">
<property name="wsdlLocation">GetPartyID.wsdl</property>
<property name="retryInterval">60</property>
<property name="idempotent">false</property>
*<property name="transaction">participate</property>*
</partnerLinkBinding>
<partnerLinkBinding name="GetPartyAcctSiteInfo">
<property name="wsdlLocation">GetPartyAcctSiteInfo.wsdl</property>
<property name="retryInterval">60</property>
*<property name="transaction">participate</property>*
</partnerLinkBinding>
<partnerLinkBinding name="UpdateShiptoUse">
<property name="wsdlLocation">UpdateShiptoUse.wsdl</property>
<property name="retryInterval">60</property>
*<property name="transaction">participate</property>*
</partnerLinkBinding>
to ensure that all database transaction within this BPEL process will be within the same session.
However, I’m not sure if this property can be used along with “idempotent” which I think initiates a new transaction as well (anyways I tried without the “idempotent” property and does not seem to work either). Also, I’m not sure if I should apply this property to the partnerlink that invokes this process that contains the above database/EBS partnerlinks. Any help is greatly appreciated.
Thanks,
