You must post the exact versions of everything you are using - which odbc, which unix, which oracle. For oracle, the version would be something like 7.3.4.
You might want to search for those things on the obsolete comp.databases.oracle group (but ask questions here).
Just making some wild stabs in the dark - try specifying upper case in the ODBC string. If you can use sqlplus like sqlplus scott/tiger, but can't in the ODBC, you might look at the way Oracle stores the username password - without quoting, oracle translates the username to upper case, but ODBC may silently quote, requiring SCOTT/TIGER. The same thing may apply to the SID, but it's been so long since I've been on 7 or 8 I can't remember which versions had which issues with that, as well as the rules for hostnames. But usually an ora-1017 means you have gotten past that. You may want to search on metalink for the ora-1017 error explanations, using the "all sources" knowledgebase to get past the ridiculous version issue your management has made. You see, that is why we upgrade, because eventually we want to use more current tools to get to the data, and they must be somewhat close, and even old stuff can need support. You may want to exp/imp into an XE db on a PC (if the data set is small enough) just to use modern tools.
