AIX Certification ... continuing story

I took two more tests - and as I feared, failed the HACMP 000-102: High Availability for AIX - Technical Support and Administration one. However, to my surprise, being honest, I passed what I thought was going to be the easiest test -  000-109: Virtualization Technical Support for AIX and Linux - v2.

AIX Certified: anno 2011

About time - I was thinking. Back in 2002 - last time I tested - I was angry about the questions because they were almost the same as what was in the certification redbooks I read the next week. I was think - how is certification going to mean anything if they are practically publishing the questions? But, I kept my pin and certificate - which is how I knew it was 2002 that I last went.

What's going on? PDF Print E-mail
Written by Michael Felt   

Been a long while since I worked a blog like entry. But so much is going on that it should not be too difficult for the coming weeks.

So what's going on with me? Keeping it limited to AIX and POWER the keywords/tokens are:
CAA - Cluster Aware AIX
HACMP (aka PowerHA, SystemMirror) and
GLVM

My goal is to be doing some writeup's soon.

Almost forgot: Versioned WPAR support for AIX 5.3!

What are your favorite tools?

My favorite tools are focused around monitoring current behavior aka performance monitoring. Until 1999 I was satisfied with vmstat as a "one size fits all" for basic monitoring and troubleshooting. In 1999 AIX 4.3.3
was enhanced with topas as a standard tool and that tool became my favorite for the more specific statistics - especially with regard to paging activity (not to be confused with paging space activity).

If I saw PAGING SPACE statistics I was fairly certain the system was poorly sized and/or tuned. AIX should not be paging to any extent that it is observeable.

My new job, well, almost 2 years now, takes me on the road (read in the air) to be on-site with customers and review and or teach about how to implement IBM's newest POWER features.

The last two months have been difficult: 1) getting a planning settled; 2) changing almost everything because "something came up" and everything needed to be scheduled again; 3) my wife does not like it when I am only home for three Saturdays in a row (if at all); my wife does not like it when I work on holidays. (Did anyone else notice that the Easter related holidays are rather late this year?).
