I have been fighting a problem at my current employers environment that has been hard to diagnose. The mail servers run on IBM’s Power Platform and iOS (OS/400) V5R4. The Domino version is 8.5.1 FP4. That said you would think that everything is going to be just fine. There is plenty of memory, plenty of CPU and about 1.5TB of extra disk space. Evertyhing should be perfect, but it’s not and you know this because I would not have started out by saying I was “fighting a problem”.
What was problem?
There are two servers. One primary and one secondary. The majority of the users would run on the primary until it crashed then as expected would jump over to the secondary. Problem was when they started to move to the secondary the server would run up 300% CPU (Which is ok in a LPAR system if you have the CPU) and eventually just crash as well leaving NO mail server, which is a bad thing.
Ater begging for help from IBM I finally got some answers about the issue. Seems there is a problem with OS/400 V5R4 that don’t make Domino 8.5.X very happy. Seems the issue lies in the way Domino does a look up on the files and OS/400 adds a 4K record to every record looked up. On a server with over 5000 users and a Domino Directory with 25,000 users and 65,000 Groups that is going to get messy. So when the fail over started the server would go nuts trying to index and do lookups to make sure everything was right and going into this spiral of doom eventually crashing. So not only was my primary down, not my secondary was down as well.
So with both server down a few questions come up; 1 . Why and 2. When can we move to Exchange.
Answers; 1. I am working on it and 2. Never!
I am still looking for the IBM Article that shows the problem.
The fix is simple upgrade the OS to V6R1 or V7R1 and it fixes the problem. But in a big IT environment it’s not that easy. So I have spent the past 6 months building new servers and moving them into place to replace the old one. Still in the process of doing this today and things are going well. The secondary server is doing good and the primary is due for a swap out in the next few weeks.

Lotus Administration eBooks?
Sun, Apr 22nd 2012 6:43p David Vasta I was in the shower, that is where I do all of my good thinking, and I said to myself….the last great Domino Book I have is over 9 years old and a few versions back, I think version 6.
It might be high time to write a new book that people can use. The problem is if you know the book I am talking about written one Brian Benz and Rocky Oliver called the Lotus Notes and Domino 6 Programming Bible and it’s well over 1032 pages of juicy Lotus goodness. I have one on my desk at work and [read] Keywords: administration

Fri, Apr 6th 2012 4:42p David Vasta So it’s been a long while since I have posted anything. I have been in the middle of a fire fight at work getting things fixed up and working. The smoke is starting to clear and frankly I have learned some new things about Lotus I need to share. There is a Twitter Account that goes along with this blog and I will be tweeting as best I can using it and the blog to try to make an impact on the businesses who user Lotus, don’t use Lotus and everyone else.

Merry Christmas Everyone
Sun, Dec 26th 2010 11:39a David Vasta I have been on a bit of a vacation. Sorry for not posting. I took 2 full weeks off and went on a 10-Day Panama Canal Cruise with Holland America. It was wonderful and I would recomend it to anyone. With Lotusphere only 30 days away it’s time to ramp up the Lotus posts.
Hope you all had a Merry Christmas and may the NEW YEAR be the best ever! [read] Keywords: administration
I want to get some . . . Lotus Training
Tue, Nov 30th 2010 9:02p David Vasta I am looking for “other” Lotus training. I know about Integro in Denver, and they are super people that supported the local Lotus User Group, but I am trying to get more of a list of places that offer Lotus Training other than IBM/Lotus. I am also a big fan of TLCC as well.
Hit me with your favorite places to send people to train or where you go to learn more? [read] Keywords: administration
