The time-out in seconds for incoming and outgoing connections. Answer: C Explanation: Answer C is correct. In large networks, the connection pooling feature of Oracle can improve scalability by maximizing physical network connections to the multithreaded server. The set of connections made to a dispatcher are shared or pooled between many user processes. Oracle does this by using a time-out mechanism to temporarily release transport connections that have been idle. These physical connections are then available Actualtests.com - The Power of Knowing 1Z0-026 for incoming clients, while the logical session with the previous idle connection is still being maintained.
