Login problem

Hi Everybody,

I am getting following error when am trying to login to my oracle user.

su: warning: cannot change directory to /bin/bash: Not a directory
-sh: /bin/bash/.profile: Not a directory
-bash-3.1$ 

Please help me how to avoid this message and how to login with normal user login prompt.

Regards,
Mastan

I presume the oracle user's default shell is wrong is /etc/passwd ?
