14 Optimizing Performance

Learn how to optimize connection performance.

• Understanding the Benefits of Network Data Compression
  
• Configuring Session Data Unit
  Under typical database configuration, Oracle Net encapsulates data into buffers the size of the Session Data Unit (SDU) before sending the data across the network.
• Determining the Bandwidth-Delay Product
  
• Configuring I/O Buffer Space
  Reliable network protocols, such as TCP/IP, buffer data into send and receive buffers while sending and receiving to or from lower and upper layer protocols. The sizes of these buffers affect network performance by influencing flow control decisions.
• Configuring SDP Support for InfiniBand Connections
  Oracle Net Services provides support for the Sockets Direct Protocol (SDP) for InfiniBand high-speed networks. These sections describe how to set up Oracle Net support of SDP for middle tier and database server communication.
• Configuring Exadirect Support for InfiniBand Connections
  Oracle Net Services provides support for the Exadirect for InfiniBand high-speed networks.. Use the new transport to improve latency and throughput by leveraging Remote Direct Memory Access (RDMA) in an InfiniBand environment
• Limiting Resource Consumption by Unauthorized Users
  To mitigate these types of attacks, configure limits that constrain the time in which resources can be held prior to authentication.
• Configuring Key-Based Routing for Client-Server Connections
  Learn how to establish client-server connections in a sharded database by using key-based (or direct) routing. In key-based routing to a shard, a connection is established to a single, relevant shard that contains the data pertinent to the required transaction using a sharding key.
• Configuring SNI for TLS connections
  Oracle Net Services supports Server Name Indication (SNI) in order to minimize the time taken to establish client-server connection. When SNI is set, the listener forwards the connection request from client to an appropriate server without performing a TLS handshake, thereby reducing the overall connection establishment time.
