Thank you for the detailed hints! However, I tried a lot of this and that,
but without a possibility to track down what went wrong, the ways to fix
the probable problems are unbounded. Finally I get 'Driver's
SQLAllocHandle on SQL_HANDLE_HENV failed' when I start 'isql' and that's
where systematic error analysis stops and wild guessing starts. Since OCI
and sqlplus work on my machine, I'll try to follow this way.
