Just upgraded to Oracle 8 (personal edition) 8.0.4.0.0 under NT.
In a sample app I put a TOracleSession component on it and can connect to the any one of several instances. Borland's SQL explorer also works fine. However, when I try to run the same app either inside or outside the IDE I get the following error:
ORA-06413 Connection not open.

Any ideas one what is going on?
