Busting a DBMT pre-allocation Myth

Some say you no longer need to worry about fragmenation now DBMT has a new pre-allocation feature - sorry that's not the case. Let me explain:

DBMT uses copy style compacts when it's reorganizing a target database. We've written numerous times about how copy style compacts have a nasty fragmentation side-effect. See here and here and here. IBM must of been listening to us because they attempted to address this with new pre-allocation functionality in Domino 9.0.1. 

The concept is that DBMT asks Windows to pre-allocate a file as contiguously as possible and then uses this space to make the copy.  Sounds great and a vast improvement over the previous method, but can you see the problem ? 

You spotted it right ?

That's right, this works great as long as your freespace is contiguous, and the only way that's going to happen is if you have a defragmentation product mopping up the mess that routinely results from running Domino. For early adopters of the DBMTas it was delivered in 9.0, prior to the pre-allocation improvements in 9.0.1, it is a case of half closing the gate after the horse has bolted, as they will already be suffering the negative effects of serious database fragmentation as a result, unless of course they had Defrag.NSF installed.

Even with DBMT available we still see customers  using compact -c (old habits die hard). The other major fragmentation contributor is full text indexing and we have written about it before. FTI will scramble the volume's freespace.

So what are we saying ?

Simply this, if the freespace is scrambled then DBMT preallocation is going to produce fragmented files, It can only deliver optimum results if contiguous freespace is available, and that's only going to happen if something is actively defragmenting it.  And for that we recommend Defrag.NSF (shameless product plug). 

So it's interesting to note that the pre-allocation functionality, introduced to help reduce DBMT related fragmentation works even better when Defrag.NSF is installed.
Thanks for reading.

New Business Partner BlazinglyObvious to release XPages Connections clone.

New business partner "BlazinglyObvious", located in McMurdo Antarctica  has decided to release Domino XPages applications that are functionally identical to IBM's Connections product.

During the product announcement their CEO, Captain Obvious said "We've spoken to numerous Connections customers and they've told us that they're having trouble installing the product. Apparently the process of downloading 10's of GBs of files, patches and cumulative updates for multiple disparate products, assembling and installing them (with conflicting hyper-linked based instructions) is proving to be harder than the stealth marketing department had advertised. One customer even described the process as 'hard'. 

We took a close look at this and decided that maybe selecting File -> Application -> New from within Notes was easier. We've since had this belief confirmed by early adopters of the product  who were also delighted with the 2 minute installation process. They also liked the fact that the solution runs on a single server and existing Admin skills could be used. Furthermore, upgrading the software is as easy as performing a Replace Design.

Analysts  from leading research organization "HyperCurveMaximus" believe BlazinglyObvious's approach may be well received by existing Domino customers, but they are not sure how others will feel about it.  They said "This approach worked well in the 80's  but it is unclear if it is compatible with the industry's current Rip and Replace strategies and the general quest for increased complexity while simultaneously providing less functionality at maximum cost".  HyperCurveMaximus also felt it was unclear how this will help drive new services sales or force people to the cloud. Only time will tell.

BlazinglyObvious's xPages Connections will be available on the 34th of Octember, 2014.

4 years ago we posted this graphic of Domino vs Exchange, true then, true today !!

Rather than Lotus knows, maybe it should be 'We all know' !

Does anyone know how to decrease the delay before inviewedit fires ?

This is in the Notes Standard client... I've looked and look... starting to pull my hair out... please help.


We made it into Connect 2014 and didn't even know !


I've been reviewing different bits and pieces from Connect and noticed that in John Paganetti's excellent presentation "ID104 - Best Practices for Upgrading IBM Notes and Domino 9.x" our work got a mention on page 42.



 
I'm really proud of the work we've done in this area and it's great to have IBM recognized our efforts and research in this space.


Thanks again John.

What's the difference between Project Vulcan and IBM Mail next ?

Can anyone at Connect let us know ?

Remember this:

ORLANDO, FL LOTUSPHERE - 18 Jan 2010: Today IBM (NYSE: IBM) unveiled IBM Project Vulcan, a blueprint for the future of collaboration.

Building on a company's existing investments, IBM Project Vulcan enables breakthrough approaches to reduce personal information overload and improve business agility, empowering people to drive better business results.

IBM Project Vulcan is designed to exploit the convergence of:

Was project hawthorn discussed in the OGS today at Connect ?

I haven't seen anything on it yet, but did IBM talk about it ? Can anyone at Connect let us know ?

BTW I bet the most heavily attended sessions at Connect are focused on Domino and Notes... where is the love !!!
