HP-UX

Hello rhfrommn,

This is very kind of you.

As mentioned in my reply to buffoonix, I found some info about my question but you response shed some more light on the issue.

If I understood this correctly, when you change the run level of a Sun Box to (init 0) running the Oracle database, will shutdown your Oracle database and when you change the run level to init 6 to bring up the Box will result in executing the script placed in /etc/rc2.d which starts up your Oracle database. I hope I got it right!!!

On a different note, I was wondering if you be happy to let me know your e-mail address as I have difficulty to log into my Hp-ux (C200) workstation running on Hp-ux 11.x Operating System.

Well, once again many thanks for your time and I look forward to hearing frome you.

Best regards

Yes, when you change runlevels it runs the scripts in /etc/rcX.d as they go through that level. Scripts with a K in front of the name are run with a "stop" flag, and scripts with an S are run with a "start" flag. So the oracle DBAs will put a script in that handles their shutdown and startup tasks.

Using init 6 changes it from runlevel 3 (the normal running level) to 0 then back to 3 again. Runlevel 6 is a special "reboot" runlevel which the machine actually never stays at - telling it to go to 6 just makes it reboot by going to 0 then immediately to 3.

All the above info is for Solaris. I think most of it applies to HP-UX (at least the general ideas) but the specifics may be different. Unfortunately my only exposure to HP-UX was a 3 month contract with a few HP machines I did over 2 years ago, so I know not much at all about HP-UX. Sorry I can't be of more specific help there.

Hello rhfrommn,

This is very good of you explaining it so clear. As mentioned in my last thread, I am having difficulty to intract with the IPL by pressing "Esc" key soon after powering up my Hp-ux (C200) workstation which is running on Hp-ux 11.x. Shame, that your HP-ux is not as good as your Solaris. I do not know how to deal with it as I am new with unix operating system!!!!!

Well, once again many thanks for all you kind response.

Best wishes

As far as the HP-UX boot process is concerned
I only have some experience with HP enterprise servers
but not HP workstations.
The server HW is usually equipped with a so called
Guardian Service Processor (GSP) - similar I guess to SUN's NVRAM -
Although I doubt that the PDC for an HP workstation incorporates the
same functionality as for HP servers, they might however behave similarily.
Through an attached terminal at the console port you can access the GSP
by pressing ^B (i.e. Ctrl+b key).
Usually, if Autoboot is enabled an HP box will after the POST phase
(which can take up to quater of an hour, depending on how many Gigs of RAM
are installed) display for 10 secs a screen where it asks to press *any* key
to bypass the autoboot and possibly interact with ISL.
Having pressed any key you can e.g. search boot paths of attached bootable media.
Having entered "bo" you will be asked if you want to interact with ISL.
Just type "y" here and you will get into ISL.
If you go to docs.hp.com you can search for your HW and you will find docs
that describe the features of your box as well as docs that describe the HP
boot phases.
There should also exist manpages for hpux, pdc, isl on your box.

Hi buffoonix

Many thanks for you response. This is mydilemma. To start, I am not a System Administrator but am teaching my self about Hp-ux Admin tasks.

To get to the point, I have a Hp-ux (C200) workstation running on Hp-ux 11.x Operating System. Couple of weeks ago when practicing on file access permission, I have set the permission on a directory (perhaps a file I am not sure) to 0544 and did some other practic (vi) and then turned the machine off (shutdown -yh 0).

When next day I powered up my machine and wanted to login as a root through CDE, I got this message:

"account locked in the commercial security database"

I tried to interrupt the boot process (to interact with ISL ) by hitting the Esc key soon after turning the power ON, but I could not interrupt the boot process.

I turn power ON, kernel gets loaded, CDE appears ready to login and when I login as root, I get the above message. I do not know what to do.

rhfrommn and you are very kind in responding to my threads and on that note, I thought if you could help me to resolve this problem.

Many many thanks for you time.

Hello,

I'm pretty much at the end of what I know here, but I have one last suggestion. I know in the FAQ section on this site they have instructions for how you can recover a system where you lost root access due to forgetting the password or the account getting corrputed or whatever. If you check the instructions for HP-UX maybe you could use those to boot into some kind of maintenance mode and fix the root account that way. Unfortnately like I mentioned before my HP specific knowledge is way too small to know HOW to do that part, but I would think there has to be a way to fix it once you access the machine in maintenance mode.

Good luck.

Oh, one other thing. When I did have that short contract working on some HP-UX I found that HP had an absolutely fantastic support forum. By far the best vendor-specific one I've ever seen, way better than Sun's bigadmin site for example.

Here is the link to the start page. I think you can sign up for access even without a vaild HP support contract.
