Hi Sudheer,
Firstly, I'm not sure OpenACS is supported on 10g, but I think it should certainly work. Maybe someone else can answer that.
Here are some install docs - it'd be a good idea to check you've done everything here:
https://openacs.org/xowiki/oracle-install
https://openacs.org/doc/current/oracle.html (an older one)
Looking at your error:
"couldn't execute "/home/oracle/bin/loadjava": no such file or directory". It seems that you don't have Oracle fully configured to run OpenACS, specifically the Java stuff.
