Applies to:

Oracle Service Bus - Version 10.3.1 to 10.3.1 [Release AS10gR3]
Information in this document applies to any platform.

Symptoms

In an OSB clustered environment, one file poller is configured for one Proxy Service (PS) as a singleton resource where only one managed server can poll the directory.

Oracle Service Bus Deployment Resources - Singleton Resources

File Transport Configuration page - Managed Server

However, sometimes the file poller is running on two managed servers for the same Proxy Service, resulting in duplicate processing.

Changes

Manually switching the file polling server to another one, this issue could happen.
