Hi,
Please specify whether you have installed CI and DB on two different machines (hosts).
Have you given proper entries when asked about Database Server during your CI installation ? Check the SAPDBHOST parameter in the DEFAULT.PFL
If yes then have you installed oracle client on CI ? You will have to install it.
Please check and reply.
Regards,
Suhas
