hello,
i want to install oracle 8i on HP9000 server which is of RAID 5 technology and OS is HP-UX. Actually my problem is i have to install oracle 8i and i have to mirror the disk.

and one more thing is, Is prallel server and Clustered Server is same or different ? and I want the database must be available at all times.
I want the server as, If one server failures another server should handle the process. and what are the steps to be taken.

it is very urgent, tomorrow i have to install the server.
