From RFC 2068
<i>Hypertext Transfer Protocol -- HTTP/1.1</i>
The error can happen from SOAP UI, Postman or EBS ISG Test Client
as well.
The same error can happen when the input XML is not properly
parsed. But the error explained here is unrelated.
This typically happen when the service is invoked several times and
very frequently. Due to some internal issue, EBS create multiple records in the
resultant table.
Cause:
Duplicate records are created in “fnd_log_transaction_context” table due to Oracle EBS Bug.
Solution:
Step 1: Get Class ID of Problem Web Service
ICL.CLASS_NAME, ICL.IREP_NAME, ICL.CLASS_TYPE, ICL.PRODUCT_CODE, ICL.SOURCE_FILE_PATH, ICL.SOURCE_FILE_NAME, ICL.DISPLAY_NAME
FROM APPS.FND_SOA_SERVICES FSS, FND_IREP_CLASSES_VL ICL
WHERE FSS.WSDL_URL LIKE '%<Service Name>%%'
AND FSS.CLASS_ID = ICL.CLASS_ID(+)
--AND WSDL_URL LIKE '%/rest/%' -- get only RESTful Web Services
ORDER BY FSS.SERVICE_ALIAS;
Step 2: Identify any service that has created duplicate records in FND LOG
Transaction Context (fnd_log_transaction_context) table
from fnd_log_transaction_context
where transaction_type = 'SOA_INSTANCE'
group by transaction_id
having count(*) > 1;
Step 3: Delete the records: Replace the transaction_id in query below from
the able query results.
where transaction_type = 'SOA_INSTANCE'
and transaction_id = < transaction_id>;
System will automatically create new record in the table, when the
web service is invoked first time after deletion.
No bouncing or Functional Admin Cache Clearing is required for this
solution.
