Hi,
We run oracle 9i server & 9i clients,however I',ve recently installed a 10g client one of my PC's and configured my

TNSNAMES via the net configuration.
but, I keep getting the ora 12154 error.
I've replaced the tnsnames(and sqlnet too) with those of the other PC's running 9i client but still cant connect even

after tweaking it. I'm able to successfully ping the server though.
My question: Is 10gclient compatible with 9iserver(i know ther work the other way round)?If so ,any suggestions on

what I might be missing?

ps see an my tnsnames below.
Many Thanks
