||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 ?
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

Get those Domino System Databases back in shape with Defrag.NSF|

We often see Domino servers with bloated System databases that never seem to get compacted/maintained (you know the ones.... log.nsf, etc) because.....well it's just always been a hassle for many admins to shut down and manually do it. As a result, these databases are missing out on some much needed maintenance and can get pretty huge and often respond sluggishly when they do need to be opened. Usually with many GB of disk space trapped inside they are just wasting disk space too, it all adds u

Domino Database Optimizer Health Check|
Tue, Jun 27th 2017 4:29a Adam Osborne
One of the first things we suggest you do when you install the Domino Database Optimizer is run a Health Check and below is a typical example of what we find. These screenshot shows a selection of some of the less than optimal results revealed on a Domino 9.0.1 server during the initial DDO Health Check. A simple button click in DDO will activate the optimizations with no further administrator effort. Then on schedule, DDO performs tasks according to the administrator's configuration fo
DBMT still creates fragmented NSF files on volumes that are fragmented|
Thu, Apr 6th 2017 8:12p Adam Osborne
On a busy server Compact -C fragments NSF files left, right and center. It sprays bits of the file all over the place. The only thing we have seen in Domino that does a worse job are full text indexes. As previously discussed and referenced by others and IBM, DBMT does a much better job. It tries to create a contiguous NSF file, but it can ONLY do that it the freespace on the server is not highly fragmented, and the only way that is going to happen is if you have taken steps to keep it in sha
Virtualizing Domino is NOT a "Get Out Of Jail Free" card|

Further to yesterday's blog we wanted to point out that recently VMware updated their latest documentation for VSphere 6.5, included is the recommendation to "Defragment the file system on all guests" to enhance Disk I/O performance. It is so often not understood that fragmentation in the virtualized environment can have a devastating impact on Domino server performance and also the O/S, and yep, we see this a LOT. This negative impact happens because as far as the Guest O/S (Windows) is co
A simple way to reduce backup times by 55%|

Last week DDO went into action at an Australian Coal mining organisation. The server was a mess, with exceptionally long backup times. It is a VM, running on a high powered SAN, but none of that matters, because if Windows sees fragmentation it acts accordingly, it slows down and in this case was issuing millions of additional I/Os to get backups done. DDO ran and optimised the files. In the chart below you can see the positive effect of removing 742,289 fragments from just 144 databases. Back
How healthy are your Domino System Databases?|
Mon, Mar 27th 2017 9:20p Adam Osborne
Are the System Databases on your Domino servers optimized and healthy? You know, the really important ones that seem to never get maintenance, log.nsf, names.nsf, mailjrn.nsf etc, are they getting huge, sluggish to open, slow to backup, wasting GB of disk space? DDO makes this often never done Domino and database maintenance as simple as ticking a few boxes, set and forget,. If this is scheduled once a week the difference it makes to Domino is quite amazing. Here are some screen shots from a c
The easiest way to enable Feature Pack 8 View Separation|
Mon, Mar 20th 2017 1:17a Adam Osborne
In this 2 minute video, we will show how to use DDO to: - Enable Feature Pack 8 View Separation (NIFNSF) with a single selection - Direct the View NDX files into their own directory - Schedule View Separation for all Mail 9 databases - Schedule a Domino restart at 12:05 am to enable View Separation. Just for good measure, we'll run DBMT over all the System Databases at the same time. - Schedule DBMT to run at 2:30 am for 2 hours, during which View separation will occur on Mail 9 databases. On
