TypedPolling from SQL and Insert to Oracle

Question

I have a BizTalk application trying to do the following:

1) Typedpolling from SQL server using WCF-custom adapter, debatch them

2) Convert and save each individual record to an Oracle database.

I can successfully typedpoll records from SQL and send them to files. I can also successfully read records from files and save them to Oracle tables. However, I can not manage to poll records from SQL and save them directly to Oracle Table. The error I received was: "Exception occurred when persisting state to the database". This is the error message in its entirety:

xlang/s engine event log entry: Uncaught exception (see the 'inner exception' below) has suspended an instance of service 'Test00070.Test_00070(7a42a905-f067-e0f9-31df-b2ae9c06b0e4)'.
The service instance will remain suspended until administratively resumed or terminated. 
If resumed the instance will continue from its last persisted state and may re-throw the same unexpected exception.

Additional error information:

The error was The message found multiple request response subscriptions. A message can only be routed to a single request response subscription.  with status -1061151949.

Exception type: PublishMessageException

This was what I did:

1. Created auto generated items using WCF-Custom for OracleDBBinding and SQLBinding.
2. From the xsd for SQLBinding, I debatched polled messages into individual records
3. Create orchestration to received polled data, transform the SQL Message to OracleMsg and then Insert them back into Oracle.

I have successfully deployed the application but once I put the records into the SQL Tables, they got pulled over by BizTalk but I have encountered the error above.

Has anyone come across the issue above?

Update: After stopping other application that might be waiting for the published message, I got this error:

 There was a failure executing the send pipeline: "Microsoft.BizTalk.DefaultPipelines.XMLTransmit, Microsoft.BizTalk.DefaultPipelines, Version=3.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Source: "XML assembler" Send Port: "SEND_PORT_00070" URI: "oracledb://oracleServer/?PollingId=TEST_00070" Reason: This Assembler cannot retrieve a document specification using this type: "http://Microsoft.LobServices.OracleDB/2007/03/ORACLE_SCHEMA/Table/ROTATION_REQ#Insert".

This is my mapping:

Answer 1

Please check you have the document specification (aka schema) installed in your BizTalk environment: http://Microsoft.LobServices.OracleDB/2007/03/ORACLE_SCHEMA/Table/ROTATION_REQ#Insert

The error indicates that the send port has trouble accessing this schema. It might be that this schema is not installed in BizTalk or that the schema is part of a different BizTalk application and the application which contains your send port needs a reference to it.
