BizTalk WCF-ORACLEDB Oracle.DataAccess.Client.OracleException: ORA-00942: table or view does not exist

Following my previous blog post, Oracle.DataAccess.Client.OracleException: ORA-00942: table or view does not exist, and once I was able to solve that last issue, I was surprised by a brand new communication error between BizTalk Server and ORACLE, fortunately for me, this time with a more explicit error message: ORA-00942: table or view does not exist.

The Messaging Engine failed to add a receive location “ORACLE_RECEIVE_LOCATION_NAME” with URL “oracledb://SERVER_ADDRESS:PORT_NUMBER/SERVICE_NAME/Dedicated?PollingId=polling_id” to the adapter “WCF-Custom”. Reason: “Microsoft.ServiceModel.Channels.Common.MetadataException: Metadata resolution failed for OperationId: “http://Microsoft.LobServices.OracleDB/2007/03/POLLINGSTMT“. —> Oracle.DataAccess.Client.OracleException: ORA-00942: table or view does not exist

Oracle.DataAccess.Client.OracleException: ORA-00942: table or view does not exist

Once again, followed by the following error:

The receive location “ORACLE_RECEIVE_LOCATION_NAME” with URL “oracledb://SERVER_ADDRESS:PORT_NUMBER/SERVICE_NAME/Dedicated?PollingId=polling_id” is shutting down. Details:”The Messaging Engine failed while notifying an adapter of its configuration. “.

The Messaging Engine failed while notifying an adapter of its configuration

Of course, these two errors are related, but the first one is the one that has more precise information regarding what is happening.


As the error message describes, the table or the view you are trial to communicate doesn’t exist on the ORACLE database you are trying to communicate.


I wish all problems were that simple!

To solve this issue, you need to contact your ORACLE team and make sure that they properly deploy the missing databases, tables, or views.
