Symptoms

After configuring encryption between the server and the client, the dispatchers are continuously dumping the following errors:


*** 2010-06-02 11:01:38.188
async error encountered when accepting new connection:
NS Primary Error: TNS-12650: No common encryption or data integrity algorithm

*** 2010-06-02 11:01:40.190
async error encountered when accepting new connection:
NS Primary Error: TNS-12650: No common encryption or data integrity algorithm

*** 2010-06-02 11:01:40.190
async error encountered when accepting new connection:
NS Primary Error: TNS-12650: No common encryption or data integrity algorithm

The server is configured to work with the AES128 encryption algorithm:

SQLNET.ENCRYPTION_TYPES_SERVER = (AES128)


If parameter SQLNET.ENCRYPTION_TYPES_SERVER is not set then the dispatchers are not dumping any error.
