Activate HTTP/2 on AS ABAP 752 SP01 Dev Edition

[albanleong]

I've just recently downloaded and installed the new AS ABAP 752 SP01 Developer Edition server. A little late to the party - but better late than never.

This is a short blog tip on how to activate HTTP/2 for this server to speed up Fiori/SAPUI5 applications. Why is this step necessary? Check out this blog by nick.yang1 - How HTTP/2 feature can improve your Fiori/SAPUI5 solution performance

The quickest way to maintain an Instance Profile is through transaction RZ10 however, I was not able to locate one when I ran this transaction on the server (see below). Weird, isn't it?



UPDATE 10/11/18: Thanks to 0281bd377f70426e8bb9d2d0005e7762's comment below, I was able to load the profiles into RZ10.

To get the profiles loaded into RZ10, go to Utilities -> Import profiles -> Of active servers



 

It'll then take a while to execute and you should then get this screen.



After getting the screen above, you should now be able to add/change the Instance Profile directly from RZ10. Note: As best practice, please use the user id DDIC when performing these changes.





If you're able to follow the steps above, ignore these instructions below. 🙂

Anyway, I am still determined to set this parameter - and here are the steps I took below:

Path to the Start Profile

To get the path for the Instance Profile, you can launch the SAP Management Console (see link below), right-click on the instance D00 -> Show Start Profile

http://vhcalnplci.dummy.nodomain:50013/sapmc/sapmc.html?SID=NPL&NR=00&HOST=vhcalnplci

Virtual Machine - Terminal

Now, go to the Virtual Machine and launch 'Terminal' app. From the command prompt, enter the following commands:

> cd /usr/sap/NPL/SYS/profile

> sudo nano NPL_D00_vhcalnplci



Find a good spot in this file and Insert the parameter icm/HTTP/support_http2 = true



Press Ctrl + O and Enter to commit the changes and then Ctrl + X to exit.

Restart the server and check your changes

You can restart the server through SMC or use the command stopsap and startsap.

To validate that the changes are active, go to transaction RZ11 and display the profile parameter.



Or, launch a Fiori application from Fiori Launchpad and use Chrome Developer Tools to display the protocol in the Network tab.



 

That's it! Now, go and enjoy faster and speedier Fiori/UI5 applications from your AS ABAP 752 server.
