[ESS] connection to Oracle does not work in ESS

[Bond, Stephen]

Further info:

When I use Rterm in a cmd shell the connection works.
When I use Rterm in a shell within Emacs the connection works.
Something must be going wrong in the way ESS does things.

Subject: connection to Oracle does not work in ESS

On 64-bit win7:

I have a DSN which tests successfully in control panel. I can connect from RGui with:
con=odbcConnect("DSNname",uid="myuid",pwd="mypass")

it does not work in ESS:

R version 3.4.2 (2017-09-28) -- "Short Summer"
Copyright (C) 2017 The R Foundation for Statistical Computing
Platform: x86_64-w64-mingw32/x64 (64-bit)

> library(RODBC)
> con=odbcConnect("DSNname",uid="myuid",pwd="mypass")


Warning messages:
1: In RODBC::odbcDriverConnect() :
  [RODBC] ERROR: state 08004, code 12154, message [Oracle][ODBC][Ora]ORA-12154: TNS:could not resolve the connect identifier specified
2: In RODBC::odbcDriverConnect() :
  ODBC connection failed

I have all the paths setup and the driver is installed correctly. Tnsping finds the db.

Let me know if anybody can help.

Stephen
