Mark,

Not sure what you're looking for but I found this doc at dutchworks. Its an HTML document on performance tuning for HPUX. Hope it helps.

A great book you should buy is

"HP-UX Tuning and Performance: Concepts, Tools, and Methods" by Robert F. Sauers and Peter S. Weygant that is part of the Hewlett-Packard Professional Books series.

Sorry to sidetrack..

Edward,
How is that book? I have it but haven't gotten around to reading it yet...still working on Hacking Exposed. But a brief glimpse of the book shows that the book is more geared towards tuning the system for best application performance.

Hi Mark:

The Technical Knowledge Base contains some very good documents. Here are a just a few:

# KBRC00000947
# UPERFKBAN00000726
# S3100002312A, S3100002312B, S3100002312C

Make sure that you are logged into the ITRC for full access. Go to Maintenance and Support -> Search Technical Knowledge Base [and choose "Search by Doc ID"].

Regards!

Santosh,

i would estimate that 1/3 of the book is geared towards applications tuning and finding out how they affect the system (and being able to point the finger at the terrible programmers you have on staff).

About 1/3 is theoretical background info (that is the part that i learned the most from)

and 1/3 is about how to using the different free/commercial tools.

It was easy reading... you can read it quickly. I'm not a expert yet in hp-ux and have learned a lot from this book (i'll read anything and everything i can find). I have been using hp-ux for about 4 years (but only about 10% of my day is involved with unix/linux... i do many more things ... i work for small company with an IT department of 2, and i'm the manager). This book was definitely worth it for me. i recommend it.

I just ran across a nifty product... it's from Presise Software. It's a very cool graphical performance analysis program that know about things like XPs... and even analyses your SQL statements. (it looks at performance from an application point of view, which is actually what you really want to do)
It even suggests what to change to increase your performance.

Worth a look, anyway.

Good luck

Hi Mary Kay,

It would be impossible to say what quick tricks you can use to tune your system. Tuning depends on what you are running on your system and how you need to address these applications (like Oracle,Informix,etc.) needs. A thread I keep bookmarked is this:
http://docs.hp.com//hpux/onlinedocs/os/KCparams.OverviewAll.html
This gives you your parms and what they do, which is the foundation of knowledge to begin. There are many threads on the Forums that will help you too....Just click on SEARCH in the upper left of your screen and type what your looking for. OR....just repost with your problem and we'll be happy to respond.
**One Tip*** Check and see what your dbc_max_pct parm is set to. If it is set to 50....then you want to reduce this, do a SEARCH for this and you'll find some great tips on it !!

Hope this helps,
Rita

....One final tip....tuning is an ongoing effort of most UNIX Admins. Most servers were not tuned perfectly in a day !!
