Sorry for crossposting - was not a great idea.

Well I already succeeded with installation. You don't need any rpms. At least in 10.2.0 the driver is already present after installation. All you have to do is to make it available through your LD_LIBRARY_PATH.

I had a bunch of parameters set, which I found at

These didn't work. I throw everything out but DSN and ServerName. Now it works. But I'd not consider this a professional installation. I don't really know what I am doing. I'd like to know the meaning of all these parameters. Some info can be found in 'Oracle Database Administrator's Reference 10g Release 2 (10.2) for UNIX-Based Operating Systems' (B15658-01). I did not find installation hints or a description of odbc.ini parameters.

I had problems using unixODBC because my software, directly accessing odbc32.dll, used latin-1 encoding which works fine on Microsoft systems while unixODBC does only accept unicode even when using the ansi function version. unixODBC provides SQLPrepare and SQLPrepareW but no SQLPrepareA. After fixing this issue my Windows App now runs on Linux.

Still I'd like to have indepth infos on the mentioned parameters.
