||Fully automate DAOS - set and forget, save diskspace, time and money
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 without the administrator having to think about it, or chase it up.
An example of this DDO processing at work.
In this example (see below) we'll target a couple of databases that make decent candidates for DAOS participation, like most Document Libraries these are full of attachments, so these types of databases make great "low hanging fruit" for DAOS.
We can see below these database are currently not enabled for DAOS participation. Note the DAOS State and DAOS Count indicating this.
Tick the box to “DAOS enable all databases using the following templates” and enter the template name, you can enter multiple template names, mail templates, etc. If there are databases based on this template type that you don’t want DAOS’d enter the name(s) in the “Never DAOSify the following databases” field.
When the automatic maintenance schedule runs, DDO will enable DAOS participation in the targeted databases and the attachments will be moved out of the databases and into the DAOS store as part of the automated DDO maintenance.
Below, we see the results after the schedule ran, the same databases are now enabled for DAOS participation, the attachments have been moved out and as a result the space savings are significant.
Below, we can also see the DAOS State has changed to "Read/Write" and the DAOS count increased.
LZ1 Compression and Data Compression have also been enabled for the databases.
The databases have also been automatically compacted and defragged as part of the DDO workflow.
If you enable the “Automatically monitor DAOS synchronization” box DDO will automatically monitor the synchronization state of the DAOS catalog and as needed a DAOS resync operation can be automatically performed to re-count all the references to NLO files. If required DDO, will initiate a resyc of the DAOS catalog at 12:15AM. If a resync is not required the operation detects that there is no work to do, and will exit immediately.
Note: IBM best practice recommends that if the catalog state changes, a DAOS resync should be performed but, unless Daoscat.nsf has been damaged somehow, there is no immediate need to do a resync. All DAOS functions will continue to operate normally except for the 2AM prune operations, which will be postponed until the DAOS catalog state is SYNCHRONIZED again.
Additional Information about DAOS maintenance: Here
DDO makes this easier, working for you to automate, and improve Domino performance, I/O and backups (and your performance as a Domino Admin), it's all easier and automated.
Stay tuned, DDO will be available shortly and is a free update to all Defrag.NSF customers

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

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

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

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

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.
