I'm not great with Linux but I'm able to muddle through. My final goal is to get RODBC working in a shiny app to connect to an oracle 11.1g data base. My first step was to set up the oracle client on the Ubuntu VM.
Ubuntu version details:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.4 LTS
Release: 14.04
Codename: trusty
I followed the instructions at:
https://help.ubuntu.com/community/Oracle%20Instant%20Client
To install the client. I also included the odbc package as well. I was able to get sqlplus to connect to the database fairly easily but the RODBC in shiny still wasn't working. When I attempted to use isql in a terminal window it failed. To over come this I installed freeTDS.
sudo apt-get install unixodbc unixodbc-dev freetds-dev tdsodbc
I have configured the following files as so.
--- /etc/odbcinst.ini ---
[Oracle]
Description = Oracle ODBC Connection
Driver = /usr/lib/oracle/12.1/client64/lib/libsqora.so.12.1
--- /etc/odbc.ini ---
[STODS1]
Driver = Oracle
ServerName = STODS1
Port = 1521
Database = STODS1
TDS_Version = 7.1
--- /etc/freetds/freetds.conf ---
[global]
tds version = 7.1
[STODS1]
host = stods1.xxxx.xxxxxxx.com
port = 1521
tds version = 7.1
with this configuration I get the following response from different commands
isql STODS1 USER PASSWORD -v
+---------------------------------------+
| Connected! |

As can be seen isql works great
However osql fails.

sed: can't read /tmp/osql.dump.25185: No such file or directory
I don't understand why osql fails and isql works as it looks like osql uses isql in the last couple of lines.
tsql also fails and from looking through the net and manuals it looks like it's due to the TDS version but i've attempted all the TDS versions I know both in the config files and by forcing it using TDSVER.
tsql -S STODS1 -U USER -P PASWORD

Unexpected EOF from the server

I think I've included most of the information but if there is anything else you need then please just let me know. I've been working at this for 5 days now so getting a bit fed up. Any help would be great.
Thanks
