Re: NT - Installing Multiple Instances - 8.0.5

I think the problem may be registry related. creating a default database during installation will set oracle_sid in the registry. better remove it to force setting oracle_sid on the command prompt explicitely. at least, that's what I make of your "pointing to another".

no problem in having multiple instances on one NT box. oracle_home has nothing to do with is - you decide where to put the database (but nt doesn't know symbolic links so yout init<SID>.ora file always resides in %ORACLE_HOME%/database
