Symptoms

In OSN
PO_ACKNOWLEDGE transaction from Supplier Trading Partner via OSN to a Peoplesoft Buyer Trading Partner gets errors in OSN and shows as SENDING after restricting SSLV3 protocol in the Middleware.

[ Oracle Supplier Network and Transport Layer Security (TLS) Support (Doc ID 1943414.1) ] indicates that OSN Test has already disabled SSLv3 and enabled TLS for Incoming transactions (from OSN into Oracle Applications like EBS and Peoplesoft), so users expect there should be no issue raised by disabling SSLv3 protocol in the Middleware. But when the SSLv3 is disabled in the middleware, the inbound PO Acknowledge transaction from OSN gets errors in OSN and cannot be received into the Peoplesoft instance.

STEPS TO REPRODUCE
1. Verify the Middleware used by the Peoplesoft application that receives transactions from OSN is setup to allow SSLv3 connection
2. Create Purchase Order in Peoplesoft
3. Send the PO through OSN Test to Supplier trading partner
4. As supplier trading partner, respond with PO_ACKNOWLEDGE transaction through OSN Test to Peoplesoft, to acknowledge the PO
5. Receive the PO_ACKNOWLEDGE transaction without issue
6. Modify the Middleware setup of the Peoplesoft application to restrict / not allow SSLv3 connection, and allow only TLS
7. Repeat steps 2-4 above
8. Check for the incoming PO_ACKNOWLEDGE and see it is not received. Review the OSN Test monitor and see the transaction got errors as shown

IMPACT
PO_ACKNOWLEDGE transaction cannot be received from supplier via OSN Test after Disabling SSLv3 protocol on the Middleware for the Peoplesoft application. This should not cause any issues because the OSN Test is already setup to allow TLS protocol and not allow SSLv3 protocol for Incoming transactions (like PO_ACKNOWLEDGE from Supplier through OSNTest to Oracle EBS or Peoplesoft Applications), but instead the transaction gets error in OSN Test when the SSLv3 is disabled on the Middleware.
