Thanks to all for the suggestions/hints/advice.  They will all be
helpful once I get this particular database up to 10g because, according
to Metalink Note 261726.1, generic connectivity is not available on
Linux until 10g.  This was "verified" by checking a 10g installation and
seeing the $ORACLE_HOME/bin/hsodbc program while my 9i installation does
not have it.  One of those situations where a feature is supported on
non-Linux platforms earlier than Linux....sigh.

Again, thanks for all the help.

I asked a similar question here a while back (HSODBC  connection to
informix), admittedly the initial googling and metalinking seemed
circular... I found this document to work perfectly 245549.1 . Be sure
to follow it to the letter, its actually easier to do than  than the
document makes it sound. This also assumes you will aquire 3 party (your
system) odbc drivers.


note 245549.1 = How to setup generic connectivity - HSODBC - on (your
platform) in this case Sun solaris

HSODBC = hetrogeneous services via odbc
