Before I could start I needed to get 11gR1 loaded. The first stages of this research are two fold, look at the documentation and of course look at 11g itself. I downloaded 11g as soon as it was available for download for Linux a week or so ago but didnt get around to installing it until last night. I had to first dig out a box to install on. I was going to vmware it then i thought, no better to run natively even if the box is not top spec. I had thought about an old base unit i have but decided that it was too old and slow and instead I have reformatted the disk of my last laptop and I downloaded Oracle "unbreakable" linux at the weekend.
I then spent Monday evening trying to get it installed.... that was a failure, wouldnt you think that Oracle "unbreabable" Linux downloaded from Oracle's site would work out of the box with Oracle 11g database.... nope..... no such luck. After some digging this last night, i solved the DISPLAY issue (Thanks to Howard) and then set about fixing the packages, kernel parameters and a few other bits. I seemed to have parameter issues that are not listed in Howards install docs or others I found. The install then went reasonably smoothly, if slow. When it had finished I got another issue. I tried to log into sqlplus but got an error "sqlplus: error while loading shared libraries: /oracle/11g/libnnz11.so: cannot restore segment prot after reloc: permission denied" - This was solved after a bit of digging to find it was an SELinux policy issue. I had to log in as root and run "tail -f /var/log/audit/audit.log | tee oracle.log" then log back in as oracle and try and start sqlplus as sysdba. The log back in as root and CTRL-C the log file. Then its a simple case of feeding the log into the policy by doing "audit2allow -M oracle < oracle.log" and then run "semodule -i oracle.pp" - now sqlplus works natively on the Linux box. I can of course also log in remotely:
