Hi 2794407 -
What are you trying to accomplish? Are you setting up database communication between DB client on Exalogic and DB on Exadata via the SDP protocol? If so, you mention Oracle documentation. Have you followed MOS Note: "Setup Listener on Infiniband Network using both SDP and TCP Protocol (Doc ID 1580584.1)"? This is your best resource. You also mention the tnsnames.ora file. Have you placed the listener entries you are referring to, i.e. LISTENER_IBLOCAL, LISTENER_IBREMOTE, LISTENER_IPLOCAL and LISTENER_IPREMOTE as entries in the tnsnames.ora file? It may be helpful to post the entries (obfuscate any sensitive info as needed) here to verify. Also verify you can tnsping these entries from the OS command line on your Exadata DB servers with your database environment sourced.
Also, please note that Oracle has recently updated their recommendation to not use SDP communication between Exalogic and Exadata - and to use TCP instead. SDP is still supported, but there have been many stability issues with using SDP and for most workload the performance gain received is not worth the risk.
The issue has been resolved.
