Here is what we need to know to understand what you are doing:
- Oracle version (3 decimal places)
- Is failover being done with TAF or FCF
- Is connection using VIPs (Virtual IP Addresses)
There is a sample TNSNAMES.ORA file for a RAC cluster in Morgan's Library at www.psoug.org under "REAL APPLICATION CLUSTERS." Look at how the host has been configured ... the host name does not even enter into the picture.
