I'm presently trying to connect to Oracle through RODBC / UnixODBC on linux (Red Hat 5). I've successfully connected through the easysoft drivers but the trial license has run out and I'm trying to connect via the default Oracle 11G driver. However I'm getting the following error

> library(RODBC)
> setwd (paste("/home/oracle/scripts/R"))
> channel <- odbcConnect("test", uid="prod", pwd="passwd")


  1. .Call(C_RODBCDriverConnect, as.character(connection), id, as.integer(believeNRows))
  2. odbcDriverConnect(st, ...)
  3. odbcConnect("test", uid = "prod", pwd = "passwd") aborting ...

The below shows the changes in the odbcinst.ini file.


Description             = Easysoft ODBC Oracle Driver
#Driver         = /usr/local/easysoft/oracle/libesoracle.so
Driver          = /u01/app/oracle/product/11.1.0/db_1/lib/libsqora.so.11.1
#Setup          = /usr/local/easysoft/oracle/libesoraclesetup.so
DontDLClose             = 1
FileUsage               = 2

Can anyone point me to what I'm doing wrong?
