Last year I published a small post to compare sapconf and saptune: sapconf versus saptune
It would seem that there is still some confusion about it, so let me go a little bit deeper into the rabbit hole today.
What is the difference between both?
If you are running “SUSE Linux Enterprise Server” you will only have sapconf in your arsenal.
It is meant only to do the most important changes and neither distinguishes between SAP applications nor implements entire SAP notes. This is often not known.
If you are running “SUSE Linux Enterprise Server for SAP Applications” also saptune is available to you.
It can apply entire SAP notes, offers prepared combinations (solutions) of notes and – to make your live easier – also allows you to simulate and verify changes made to the system. It is much more elaborated and one of the benefits of “SUSE Linux Enterprise Server for SAP Applications”
So, only with “SUSE Linux Enterprise Server for SAP Applications” you can choose between both tools.
Both tools use tuned to do their work, which means, that they cannot be used at the same time! You have do decide which one is your favorite.
Here a little table to summarize the important facts:
|Available on SLES?||yes1||no|
|Available on SLES for SAP Applications?||yes||yes2|
|Does it implements entire SAP notes?||no||yes|
|Can I configure everything?||yes||yes3|
|Do I have a verify option?||no||yes|
|saptune||→||Your system is running saptune|
|sap-* (SLES 12), sapconf (SLES 15)||→||Your system is running sapconf|
|systemd service file||sapconf.service||none|
|Recommended status of tuned service||active/disabled||active/enabled|
|Used tuned profile||sapconf/sap-*||saptune|
I have written a small shell script which will do the tests above and give some hints how to solve a misconfiguration.
