Kernel parameter adjustment for Oracle9i v2 on HP-UX 11.23

Hi all,

I've adjusted kernel parameters through SAM to prepare 2 rx4640 for Oracle9i Server and RAC installation. After clicking on reboot in SAM the system is inaccessible through telnet, rlogin or telneting through the console. I don't get the Console from the MP menu. Although I see in the CL option that the 2nd system is at the login prompt and system is ready, I still cannot access it without power cycling which I did on the 1st system. Also, how could I hookup a laptop to the console port to monitor the next system that needs kernel adjustments. Once I hook the laptop, configured it with an IP in the same subnet, I still cannot telnet to the console. Thank you in advance.

Something has been done that has trashed the kernel of the machine.

Get on the machine, perhaps by booting off of a core OS cd.

cd /stand
mv vmunix vmunix.bad
mv vmunix.prev vmunix

Then your machine will at least boot without the changes.

Then you can go about diagnosing what went wrong.

Hi Steven,

The machine will boot again after I power cycle'd it and it took the new values for the changed parameters. I attached the kernel parameters I've changed according to oracle recommendations. Maybe you can spot something there. Can you or anyone tell me if there's anything special I have to do to hook up a laptop to the console port so I can see where the system is when booting? I've used a x-over cable from the laptop to the console port of the rx4640. I can't telnet to the console after that. Thanks again.

It was the kcweb interface that was hanging the system. After making the ajustments do not reboot the system within the web interface but log out of it and SAM and reboot using shutdown from the command line.
