Generic Linux


Exadata Environment, though the same can be used for Non-Exadata Deployments that are using Infiniband
and the Linux platform supporting SDP protocol.

Configuring Sql*Net Listener using SDP/TCP protocol on Infiniband Network.   If the intention is to make usage of SDP on various environments, i.e. multiple RACKS/Clusters be sure to implement this change on all nodes.


Please Note Oracle recommends the usage of TCP instead of SDP for Exalogic to Exadata connectivity. 

Although the following instructions in this MOS note outline steps to deploy either protocol, it is highly recommended to use TCP for maximum stability.

The stability benefits provided by TCP outweigh any performance increase obtained from the use of SDP. For a variety of workloads in several scenarios, we have observed extremely good performance with TCP. In case of link failovers, TCP also resumes better than SDP due to less dependency on hardware layers.
