Do all ODBC drivers for Oracle need to work on top of OCI??

[Nagendra]

Hi all,

To access the Oracle DataBase through Easysoft or DataDirect Oracle
ODBC drivers(for solaris),is it required to have OCI installed on that
machine? What i am asking is, whether we need to have an OCI license
in addition to an EasySoft (or Datadirect license) as well, in order
to access the Oracle backend? More generally, do all ODBC drivers work
on top of the OCI itself? Or can they interact directly with the
backend?
My platform is Solaris (Sun Sparc) and Linux (RedHat on Intel)

TIA,
Nagendra.

OpenLink used to make a driver that required no SQL*Net client
installation. All of the others that I am aware of will need to use a
SQL*Net client in order to connect.
