I have a strange (to me anyway) problem with TNS. Connecting with SQL*Plus, SQL*Navigator, TOAD: I get "ORA-12154: TNS:could not resolve service name" But, tnsping returns in 100-130 msecs. ?!?!?! I'm confused. Any thoughts? Thanks, Jon Knight __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
