Hi
- You need to install 32 bit Oracle 11 G R2 client on the Windows client
- Place the tnsnames.ora under the ORACLE_HOME/network/admin/ folder.
- Add the oracle installation location under the ORA_HOME and environment variables like PATH and classpath
- Make sure you are able to tnsping the oracle instance using command in command prompt
tnsping service_name
5. Create a new datastore in the DS designer and point to the native Oracle driver using Database type.
6. Also make sure that you are able to telnet the port on which oracle is listening
