We have received a Windows application that
we are told requires "Oracle Client 10g" to run.

We tried downloading Oracle's Instant Client and
installed that, in the hopes that that would be enough,
and we are able to run queries using SQL*PLUS, so
we know the installation worked,
but the application cannot find the Oracle stuff: we
get the message

Oracle client and networking components were not found

Is there a way to get an application (apparently) compiled
with Oracle Client to run with Instant Client?

You might poke around on oradim.blogspot.com . I know I got this
working with some mysterious vendor supplied client software, but it
took a few tries to get everything in the right place and the right

system environment variable). Then when I had it all figured out, I
couldn't remember how later, 'cause it was too easy and obvious at the

Depends.

If the client needs Oracle Data Provider for .NET or the OLE Provider,
Instant Client won't do. Same if you need utilities like SQL*Loader.

But if the Oracle client is used to establish a connection via OCI
or JDBC or ODBC, it should work fine.


I guess that in this case the problem could be that the program uses some
heuristics to determine whether there is a working client or not, and these
heuristics check for some stuff that is not in Instant Client.

A well behaved program should try to access oci.dll and leave all the rest
to Oracle.

To illustrate that, let me relate my experiences with the "Microsoft ODBC
Driver for Oracle". This piece of, er, software was developed long ago and
is out of support, so has never seen an Instant Client in its days.
It stubbornly refused to work with Instant Client, and eventually I
traced what it was doing and found that it does not only check for the
presence of oci.dll, but for a few other random Oracle DLLs as well.
Why I do not know, but that prevents it from recognizing Instant Client as
a valid Oracle client.

Maybe the program also checks for Oracle registry keys or the ORACLE_HOME
environment variable, things that you do not have in a sound Instant Client
installation.


The error message you quote sounds vaguely familiar - which "Windows
application" is that?

It might eb a good idea to ask the vendor.
