SAP Lumira – Geek Tweaks
I’ve been playing around with Lumira for a while now and tried some geeky tweaks on it. Here are some of which I am sharing through this post. A word of caution though. Please try them at your own risk. For geeks only.
Trick 1: Minimise ‘low memory’ errors
SAP Lumira runs on SAP JVM. Since the entire system runs on it, there are times when insufficient virtual memory may lead to performance issues, latency etc. Increasing the virtual memory in this case, say 1024 MB for a 4 GB machine, will help you avoid low memory errors and significantly improve performance too.
How do you go about? Well, all you need to do is edit the SAPLumira.ini found on the installation folder. Voila! You’re done.
Trick 2: Import as much as you want
While importing large datasets, it isn’t unusual to encounter an error message thrown by Lumira. This happens because of the cap on the maximum number of rows of a dataset that can be imported into Lumira.
Trick 3: Personalize the Splash screen
Give a personal touch to the splash screen that you can see while the application is launched. Personalize it with photographs or funny images/texts to your liking & add some fizziness to your start.
Here are the 2 simple steps:
- Access the ‘splash.bmp’ image in the folder %HOMEPATH%\ .sapvi\ configuration\ org.eclipse.equinox.launcher\ com.sap.hilo.branding.vi_126.96.36.199406070027-1094 \ splash.bmp
- Replace the image with any .bmp image of your choice.
In case you want to revert it, simply delete the image you uploaded. The default image gets loaded automatically.
Note: Ensure that the image is in .bmp format.
Trick 4: Speed up Lumira
When you use Lumira for a long time, you may find an unexplainable sluggishness. You’d wish if only there was a way to speed things up. Well, its possible. All you need to do is clean the cache files. Access %HOMEPATH%\.sapvi\desktopCache and delete them.
Trick 5: Why should it be the default port always?
SAP Lumira uses Jetty server for rendering the charts and other visuals on the screen inside the application, and runs on port 54643 by default. But in any case you would want to change the port to something else, you can edit the file
Change the preferredHttpPort property to the port you need.
Trick 6: Log what matters alone
Log files often get bloated with inconsequeintial messages that are hardly actionable. However, it can be very helpful if there’s a method to streamline it. You can achieve this by editing the file BO_trace.ini found in the installation folder
Set active=true, importance=XL, severity=error. Uncomment the parameters that you want to include. You can also edit other parameters like the log file capacity and the log extension.
Trick 7: Creating content behind Lumira
This was the most fun part. You can build content behind Lumira that will be rendered along with the Lumira UI but behind the visualization frame. You will need to scroll down to view the extension.
Note: Extension can be loaded inside the body instead of g division to get this.
These are just a very few I found and I’m sure there are many many more. If you find any interesting tweaks, please feel free to comment below.
