I have an application that’s using Oracle.DataAccess to connect. I’ve already discovered that the footprint can be lessened by using ODAC 11 with xcopy deployment. That’s already a big win.
Ideally, though, we would like to not have to alter any path variables and have all the ODAC files in a subdirectory underneath the application’s folder. Is it possible to do this without changing the PATH variable? Is there some way to set a temporary PATH variable? Could we copy all of the files necessary to the application folder?
The general idea is that we want to isolate our ODAC files as much as possible from other applications that might be running on the same client.
System.Environment.SetEnvironmentVariable allows you to modify the process environment block. Whether that’s enough for notoriously PITA Oracle is anyone’s guess, though. 😉
