Domino Fragmentation Analyser - FAQ

What is the Domino Fragmentation Analyzer (DFA) ?
A new Free and easy to use tool that runs in a Command Prompt and will quickly analyse Domino and produce a comprehensive report of fragmented nsf files. The DFA concentrates only on analyzing nsf files and will highlight the total number of nsf files fragmented, how many fragments each of those files are in, the most fragmented nsf file and also freespace info for the drive hosting the Domino Data directory, including freespace fragments and the size of the largest fragment.

Where can I get the Domino Fragmentation Analyzer (DFA) ?
Just register and download it from here

What's required to run Domino Fragmentation Analyzer (DFA) ?
You just need a copy of the code, and an account with Local Admin Rights. When you open the command window make sure you select Run as Administrator if you have UAC on. You also need a .NET Framework 2.0+

What will DFA tell me ?
It will detail the NSF files that are fragmented, and show the current state of the volumes freespace.

Can I run DFA while Domino is running ?
Yes.

DFA show's a significant number of fragmented files, what should I do next ?
Take steps to defragment your Domino NSF files. Grab a trial of Defrag.NSF.

Domino reads data 'randomly' so having a fragmented file wont make a difference.
Wrong. The effects of fragmentation add up. Random reads will be slower, and sequential reads will be significantly affected. Backup times universally suffer.

Domino is on a VM, I don't need to worry about fragmentation
Sorry, wrong. Please review this blog post.

Domino is on a SAN, I don't need to worry about fragmentation.
Sorry, wrong. Please review this blog post.

I get an error, Error: Access to the path  is denied. What's wrong ?
You haven't open a cmd.exe and selected "Run as administrator"

Will DFA follow Domino database links ?
No, it just looks at the state of the files on a given volume. If required, run it on the other volumes that the links point to.

We use DBMT, its pre-allocation will prevent fragmentation.
If the freespace is fragmented (and it normally will be), DBMT pre-allocation helps but it is far from a complete solution. See this blog for more details

DBMT Optimizations in DDO - real world example
Thu, Dec 8th 2016 2:09a   Adam Osborne
Further to my previous post on "DBMT Optimizations in DDO that can reduce its workload by over 90%" here is a real world screen shot of what is happening at one of our clients. Now that's optimization. Why not try DDO for yourself with a free 30 day trial?

DBMT Optimizations in DDO that can reduce its workload by over 90%
Thu, Dec 8th 2016 12:23a   Adam Osborne
DDO includes three optimizations to DBMT that make a dramatic difference in its workload: The first and most powerful setting is the “Only Compact when Freespace exceeds” fields on the Optimization Schedule. By setting this field a database can only become a candidate for DBMT compacting when the freespace within it exceed the amount specified. This avoids potentially processing hundreds of database where little, or no, freespace can be recovered. This dramatically reduces DBMT processin

What are the stages of optimization in DDO?
Fri, Dec 2nd 2016 3:16a   Adam Osborne
One of the great features of DDO is how it works through its optimization stages automatically to ensure you get the best 'bang for buck' from your Domino server. The first stage is ensuring database properties on databases inheriting design from the mail template (or other identified templates) are set correctly. Any databases out of line are quickly put back into line. Stage two optimization ensures databases that need to have DAOS applied, have it. Any new databases created based on the i

New product - The Domino Database Optimizer – DDO.
Thu, Dec 1st 2016 4:32a   Adam Osborne
We are delighted to announce the general availability of our new product - The Domino Database Optimizer – DDO. The DDO combines the power of DBMT, with the intelligence of an inbuilt configuration tuner while also integrating everything we’ve learned developing Defrag.NSF. We’ve wrapped it in a single application, with a super easy to use user interface and scheduler. It is designed to work on all types of storage systems from direct attached, SSD, NSA, SAN or virtual. No matter what

Fully automate DAOS enabling database - set and forget, save diskspace, time and money
Thu, Jul 21st 2016 2:55a   Adam Osborne
If you have a DAOS enabled server with mail files or other databases like Document Libraries containing attachments on your servers that may have slipped through the administration cracks and not been enabled for DAOS participation, even though they should have been, (possibly as an administrative oversight?), this functionality in DDO will automatically DAOS enable those databases and get those attachments into DAOS, it will also automatically pick up any new databases created in the future wit

News from the Lab - System Database Optimization - So easy with DDO!
Sun, Jul 17th 2016 6:39p   Adam Osborne
We often see customers with bloated System databases that never seem to get compacted/maintained (you know the ones.... log.nsf, etc) because.....well it's just a hassle for many admins to shut down and manually do it. As a result, because these databases are missing out on some much needed maintenance, can get pretty huge and often respond sluggishly when they do need to be opened and with many GB of disk space trapped inside are just wasting disk space too, it all adds up costing time and mon

Arriving soon.. The Domino Database Optimizer.
Thu, Jun 23rd 2016 11:58p   Adam Osborne
For the last six months we've been working on our next Domino product, The Domino Database Optimizer. The DDO (Domino Database Optimizer) is a database-oriented utility that automates and greatly simplifies the optimization of Domino databases and their maintenance. All activities are done through an integrated control panel where tasks can be done either manually or scheduled for overnight processing. The primary focus of the DDO is maximising the performance of your databases and the Domin

The Domino Database Optimizer. Our new product is on its way - Preliminary testing on SSD
Sun, May 15th 2016 11:19p   Adam Osborne
Our new product is undergoing preliminary testing in our lab and is showing some great performance gains even with Domino attached to the latest SSD storage technology. We are using lightning-fast SSD storage here and seeing these results. It's further proof that even though a super-fast storage/back end will help it is not a complete performance solution and in fact true optimal performance results from acknowledging and tuning each individual component of a system. To not apply that basic pr
