送信または受信されるパケットには、それぞれ、---> Send nnn bytesまたは<--- Received nnn bytesという接頭辞が付きます。これは、このノードがnnnバイトの特定のタイプのパケットを送信または受信していることを示しています。この接頭辞によって、ノードがクライアントかデータベース・サーバーかを判断できます。接続要求は、常にクライアントから送信され、データベース・サーバーまたはリスナーに受信されます。
例16-17は、-odオプションを使用した場合の詳細情報の出力を示しています。この出力には、接続のネゴシエーション時に接続データとともに送信されたすべての詳細情報が表示されます。
