RE: need an 8.0.5 client and an 8.1.7 client on same machine

There is an Oracle home selector that could be run before starting the appropriate application (alters path & possibly does things to registry as well).

This should guarantee the application finding the correct dll's etc.

However, the home selector is a GUI application and I don't believe it has a command line interface (I remember reading a Metalink article on this but I don't currently have Internet access available). You could use a Windows scripting tool (eg Microsoft scriptit) to pass keystrokes into the home selector but I haven't tried it.

Also, you may need to put the tns_admin variable into the registry as well as the environment variable - see Metalink Note:1020336.102 details here.

All this said, have you tried using the 817 client with the other application - it might work (but whether the vendor would support it is another questions).

Thanks.. I will try this.. Is there anything else to be concerned about? Paths
etc? I think there's a chance that the respective apps will find the correct
dll's in the correct bin directory automatically, but I'm not sure. Any problem anticipated with that?
