rman not starting on Linux

Hi all

I have installed Oracle 8i (8.1.5) on Linux 6.2
Here However I found that the rman is not working
when I issue rman or ./rman command on $ prompt
It remains in the hang mode. I have to cancel that session using Ctrl-C. What can be the problem. How to Invoke rman on a linux platform

That is because you are trying to run another rman.
execute command:
which rman
and you will see that it is another one.
try to run ~ORACLE_HOME/bin/rman
and you will see difference.

Thanks Dmitri

That is working
