Re: ORA-12154: TNS:could not resolve the connect identifier specified orafad Jun 26, 2006 2:37 PM (in response to 509395) It's a shame so many people have to spend so much time trouble shooting this ORA-12154 error.Agreed. Oracle guys should come out with a definitive answer.Dont think they can give you one. It depends on your specific installation(s) and configuration. It could be some multi-home issue or Oracle Net domain name related.... To start with, you should check which Oracle home you are using really (registry, PATH etc.), then check that sqlnet.ora and tnsnames.ora "matches". Basically, If error says that tns name cant be found, this is what you should look into
