The next level is the HP-UX Certified System Engineer (CSE.)

This is the HP-UX CSE book, "HP-UX CSE : Official Study Guide and Desk Reference," with 1704 pages of material for concepts from 2004 by Charles Keenan, September 10, 2004.

If a deeper understanding of HP-UX is required, then I strongly suggest the "HP-UX 11i Internals," with 432 pages of material for concepts from 2004 by Chris Cooper, January 22, 2004.

Sometimes you buy a book and wonder if it is any good or not.

This book provides excellent, thorough and detailed information on HP-UX S/W and the platform H/W.
It is a hard-cover book, and it is about 1700 pages. This book touches on PA-RISC and Itanium Servers with SuperDome.

HP Systems Engineer

While this book is quite the industrial doorstop and is rather daunting for newbies, it serves as a nice reference and does a great job explaining in-depth such things as VxFS/JFS, kernel options, and memory utilization. There is a section on identifying bottlenecks that I found particularly interesting. With the new exams coming out (soon or already), its usefulness as a study guide is somewhat diminished, but the information contained should continue to be valid for years to come. One of the nice things about operating systems at this level is the long lifetimes and backward compatibility.
