Unsurprisingly we require a user to hold the Oracle database. Since we have no desire to relink the Oracle kernel (more about that later) we have to accept the Oracle defaults for user name and group name. This includes the user ORACLE and the group DBA.
Login as Root
Create the oracle user and the group dba.
$ groupadd dba
$ useradd oracle
Ensure a home directory is created for the user oracle.
Unfortunately the Oracle Installer on the SCO disc will not work. A variety of problems can be experienced, from core dumps to hangs. As a result we need to copy the files from the CDROM manually and uncompress them:
Oracle tools require the messages to be in the $ORACLE_HOME/tool_name/mesg directory.
So, move the msb files from the msg_ship directories to the mesg directories.
