Hi UNIX WORLD

i have a problem and not able to solve plz any body help me to solve
this one.

I want to install ORACLE 7.0.2 in SCO UNIX 5.0.5

what action i had made to install ORACLE 7.0.2 in SCO UNIX 5.0.5 these are...

1- I made a " dba " group and then i made " oracle " user and make it
" dba " member as well.
2- I made two directories named " cdrom " and " orainst " in oracle user
3- I made two directories named " cdrom " and " orainst " in root user
4- and mount cd in cdrom by this command
# mount -r -f HS,lower /dev/cd0 /cdrom
5- and then go into orainst directory of root and run this blow one
being connected by oracle user.
$ start.sh

What happend...
~~~~~~~~~~~
1- when at first time i run this scrip and found errors those tell (means
like that ) no able to make cdlink directory.
2- and when i run this script haven connected by root user so, makes
cdlink directory but makes some others error.
3- and again i run this script by oracle user so, it shows me that i have
established link to oracle user's cdrom already and this link will be
used.

MY Question is that weather these steps are right or not. if not so, what are right steps. if yes, it means i have to make changes in SCRIPT of
" install.sh ".
please tell me what the changes are to be... plz tell me all...
OK
