Remember the program conversion when loading 8.5.x

 I want to remind everyone that the Lotus Domino 8.5.x installations are saved to release V6R1 for the iSeries.  I recently worked with a customer to upgrade their environment to 8.5 and installation of the Domino server code took over 3 hours.  Their OS level is V5R4 and they have an older model 810. 

Once the installation was underway, the CPU utilization on the iSeries server hovered in the 70-95% range for the duration of the installation of the Domino 8.5 code.  There were 3 jobs consuming the majority of the CPU:

LDFX01
LDFX02
LDFX04

These LDFX jobs are the jobs associated with doing the program conversion.  Interestingly enough, they were only visible through the WRKSYSACT command, they did not show up in WRKACTJOB.  This is how the good old CFINIT jobs behave as well.  You have to have the performance tools loaded on your iSeries server to use the WRKSYSACT command.

Beware when installing Domino 8.5.x on a V5R4 system, the program conversions will increase installation time.  While my customer experienced an increase of 3 hours+, newer, faster systems will see shorter program conversion times.  One the newer hardware, the program conversions can be done in around 10 minutes.

Make sure you plan for the added time the installation will take due to the program conversion and ensure you don't decide to do the installation during production hours because of the significant increase in CPU consumption.  The multi-version capability has made this a regular practice in a number of iSeries shops.  While this normally has no impact on production applications, the program conversion can cause performance concerns to other applications running on the iSeries server.

The program conversion will also happen when installing 8.5.x hotfixes on a V5R4 system.

Hi Kim,

What I usually do is create savefiles of the license programs on a v5r4 box (without any applied hotfixes). Whenever I upgrade a v5r4 system I use these savefiles and save me and the customer from the conversion headaches. I do lose the comfort of the installation wizard, but if you know your way around a few FTP and RSTLICPGM commands it will save you a lot of trouble.
Let me know if you need more info to use this approach.

Hi Hans, you are correct, this is the way to work around this issue, however most customers prefer to use the wizard for the installation. I hope my post gives those going down this road a heads up that the installation can take longer due to the program conversions.
