Re: rac & client connection

ORA-12545 would mean that DNS lookups for rac1pub/rac2pub/rac3pub are failing. Do a command-line "PING" to see if the Windows client can see those hostnames. Check if they are in the DNS server.
If you errors are "random" it could just mean that the Windows client isn't finding
the hostname it is attempting. You have configured LOAD_BALANCE so the client would not always atttempt the same name "rac1pub" -- at times it would attempt "rac2pub" or "rac3pub" -- and one of them is missing from DNS lookups.

If you don't use a DNS server, you'd have to hardcode those entries in WINNT\SYSTEM32\DRIVERS\ETC\HOSTS
