Verify that recv_buf_size (and send) are in fact enabled?
Is there a way to confirm that SEND_BUF_SIZE, set in sqlnet.ora on both source and dest along with RECV_BUF_SIZE are indeed being used?
I tried client_trace=16 but nothing in there that I can find shows this info.
We are trying to validate the findings of the white paper Data Guard Redo Transport and Network Best Practices to see if the above parameters can give us the performance gains outlined in the whitepaper. So far we have not seen any significant improvement -- hence the question -- can we prove that the values are being used.
