OSB flow not working properly when remote SFTP server is in cluster (Doc ID 2905780.1)

Last updated on JANUARY 30, 2024

Applies to:

Oracle Service Bus - Version and later
Information in this document applies to any platform.


1. Service Bus
3. SFTP server is a cluster of two nodes
4. Two different public keys (each public key from two nodes of the SFTP server) have been added to the
$HOME_DOMAIN/config/osb/transports/sftp/known_hosts for the same sftp hostname, like:
[sftp.test.server]:6710 ssh-rsa AAAAB1...
[sftp.test.server]:6710 ssh-rsa AAAAB2...

In case SFTP cluster had multiple nodes (servers), there is issue on OSB side

<OSB-381827> <Key Mismatch for host [sftp.test.server]:6710>
<OSB-381828> <SFTPClientException occurred, message is :: Key Mismatch for host [sftp.test.server]:6710>
<OSB-381602> <Error encountered while polling the resource for the service endpoint ProxyService$myproj$Proxy$File_Notification_In: Key Mismatch for host [sftp.test.server]:6710>
