Error while invoking stored procedure from BPEL process

Question

Hi Folks,
I am facing the below mentioned issue while invoking a stored procedure in BPEL process :
I am trying to invoke a stored procedure from a BPEL process. The process runs fine for the first/second time, but gives the below error after that whenever i try to run the process :
file:/oracle/orasoa/bpel/domains/default/tmp/.bpel_ProvisionOrderASAPReqABCSImpl_1.0_50dd1595129e9bbb00560e31e7c18cef.tmp/DB_CALL_GetPendingSubscriptionProc.wsdl [ DB_CALL_GetPendingSubscriptionProc_ptt::DB_CALL_GetPendingSubscriptionProc(InputParameters,OutputParameters) ] - WSIF JCA Execute of operation 'DB_CALL_GetPendingSubscriptionProc' failed due to: Error while trying to prepare and execute an API.
An error occurred while preparing and executing the PROC_GET_PENDING_SUBSCR API. Cause: java.sql.SQLException: Io exception: Connection reset [Caused by: Io exception: Connection reset]
; nested exception is:
ORABPEL-11811
Error while trying to prepare and execute an API.
An error occurred while preparing and executing the PROC_GET_PENDING_SUBSCR API. Cause: java.sql.SQLException: Io exception: Connection reset [Caused by: Io exception: Connection reset]
Check to ensure that the API is defined in the database and that the parameters match the signature of the API. Contact oracle support if error is not fixable.
I am not getting how the BPEL is referring to the DB wsdl from the tmp folder. To resolve this issue, we have to stop the SOA server, delete the tmp files, and restart the server.
Any pointers in this regard will be really helpful.

Answer 1

First of all does this scenario occur again.
"Works first/second time. Later gives this error."
After you restart the SOA server are you able to reproduce this scenario?
As already pointed out and from the error message, database connection is reset.
If you find this error again, try this out.
em -> home / oc4j_soa -> Administration -> JDBC Resources
Use the "Test Connection" option for the Connection Pool that you are using for your database JNDI.
It comes back and say "Connection to "XYZCP" established successfully." it is good to use.
Run the BPEL process again and once you find the error, come back and test the connection.
If it comes back with Error, diagnose based on the error message received.
