While installing Oracle Database 10g base release on HP Unix Itanium Server with OS kernel version 11.31 we were unable to start the OUI and got following error:
Checking Operating System Version Must be B.11.23 Actual B.11.31
After hours of digging through the the documentation available on the internet specifies the following reason for it and proposes a workaround which unfortunately is not entirely correct...
The installer attempts to make sure that you are using a certified combination of product and OS.
If you want to override this, try using:
./runInstaller -ignoreSysPrereqs
To quote the documentation:
__________________________________________
Install following operating system patch.
PHKL_35936
To ignore the system pre-requisite test during installation use-ignoreSysPreReqs flag with runInstaller.
__________________________________________
It is telling you that install the required OS PATCH and when you run the Oracle installer use the -ignoreSysPrereqs option on the command line:
./runInstaller -ignoreSysPrereqs
However even after installing the required Kernel Patch and executing the runInstaller with the required switch the OUI failed to start...
Further investigation relvealed the following and a FIX for it.
This is due to internal OUI bug with Montecito Processor.
What it means is that the JRE version bundled with Oracle Installation is incompatible to invoke the OUI while running on a machine hosting MONTECITO PROCESSOR. It is worth to mention that it is not possible for any System Admin to diagnoze the exact Processor Family from command line. Your Harware vendor needs to be contacted for this diagnoses..
However, this provided the much required solution to our problem... and we were able to invoke OUI by using following command.
./runInstaller -jreLoc <path of JAVA1.4>/jre -ignoreSysPrereqs
Lesson learnt: never underestimate any task :)
