Oracle’s acquisition spree has wound up producing odd bedfellows.

I would not wish this task on my worst enemy. My friend, good luck and best wishes but I’m afraid I just can’t help you, because that much suffering is way too much for me.

Just wanted to quickly mention an excellent new blog, the Oracle Multimedia Blog, that might be of interest to some of you.
It’s run by fellow Canberra resident, Marcel Kratochvil, a well known Oracle identity, who is almost as well known as myself but nowhere near as good looking
Marcel and I go way back, having worked together […]

Anyone following my tweets last night would know I installed Vista SP1 and VMware Server 1.0.5 last night.
While I was doing the Oracle workshops I didn’t really want to mess with my laptop much, but now I’m having a right good rummage.
The Windows Vista SP1 installation took about 45 minutes and didn’t report any problems. […]

Tonight I am catching up on older e-mails — here’s another question that came to me about 2 weeks ago from a user group member that I never had time to research and answer. I have directed the original author to this post so questions you pose in the comments can be answered.
Do you […]

Hi all,
I was asked this question in an e-mail — feel free to ask your questions in the comments, as I will point the original author to this post to answer those questions. There is not a lot of data here, so instead of me asking questions in an e-mail I figured I would […]

This week I’ve been looking into Oracle’s resource manager. It is a bit like “nice” for Oracle, only smarter and more complicated.
The idea is that you can create “consumer groups”, which is subsets of sessions divided by different criteria, and then decide how much CPU each group will get
There are relatively few streams resources around, […]

While going through the latest at Jerry Pournelle’s, I bumped into this:

Techniques of Systems Analysis

Back in my prior life as an Engineer, Herman’s writings were some of the most prized. The Rand Corporation represented for many of us the creme-de-la-creme of top engineering and design skills.

If you feel like getting enlightened on the seminal work that resulted in IT System Analysis as

vi not found in single user mode in HP-UX 11i v2:

For doing some file system changes i had to boot the Itanium Integrity rx7640 HP-UX server in single use mode and when I tried to edit /etc/fstab file using vi, I received unexpected “vi not found” error :

Get into HP-UX single user mode:

Interrupt the boot process by pressing any key to get into Single user mode

From the shell prompt in Single user mode I tried to ran vi and received this message:

Steps to Fix vi not found error in HP-UX 11i single user mode

This happens when /usr filesystem is not mounted, so i ran mount command to mount the /usr filesystem on my HP-UX 11i v2 server:

OK /usr is mounted now to run vi but remember you wouldn’t be able to edit files using vi until you mount /var filesystem else you will get this error when you run vi command

Mount HP-UX /var filesystem in single user mode:

Booting HP-UX Integrity server from EFI

During HP-UX integrity initial boot ,EFI(extensible firmware interface) boot manager loads \efi\hpux\hpux.efi, which reads the \efi\hpux\auto file to determine which kernel and mode to boot. You can interrupt the HP-UX kernel loader when prompted and

Type the HP-UX kernel and mode to boot from

Examples:

To list the contents of /stand:

To view the contents of auto file:

To boot HP-UX from the backup kernel :

To boot vmunix kernel into multiuser mode:

To Boot HP-UX into single user mode:

Boot HP-UX without checking LVM quorum:

Boot HP-UX into LVM maintenance mode :

Boot HP-UX into tunable maintenance mode :
