Oracle Database Discussions

Hi,
I tried to install Oracle 8i on Solaris 2.6. Installation went fine with out any problems. I followed Oracle install doc to install. I created groups ORADBA, ORAOPER and oradba ( instead of dba group ) and added oracle as it user. the problem came when i tried to create a new database in the installation process.
it is saying of "ORA-01031: insufficient privileges"
then i stopped and logged in server manager svrmrgl and gave this commands to 'connect internal' it is asking for a password. I don't know what to do.
I would really appreciate if you can help me complete the installation process

here is scripts which is called in Oracle installer
