2284028 - SUM SL Common UI : Troubleshooting problems with the new SUM UI

Symptom

You want to run an upgrade on a system and you configure the SAP host agent for Software Update Manager (SUM) UI as per the guide. After this, you are having troubles when launching SUM via browser. You try to access the SUM UI relevant link for your scenario (ABAP/Java/Dual Stack):

Above links are for http, but for https (Use port 1129 instead).

The link is not reached or the browser shows the following random error messages:

  • Internal Server Error Operation [id=00505689237B1ED5B4FDC6FE9AA95220] terminated with errors : 127 (null)
  • Webpage cannot be opened HTTP 404
  • Internal Server Error (Status code 500)

The error messages shown above could be different but the underlying problem may be the same as different browsers could show different messages for the same underlying issue.

How the SUM SL Common UI Works?

For the new SL Common UI, The entire communication happens through the SAP host agent. The below figure from the Guide illustrates the same.

So, even if it seems like the problem is with SUM. It could be very much because of the SAP host agent. (Faulty installation, Incorrect permissions etc.). Two important logs that can help in troubleshooting SL Common UI related Issues on SAP host agent side: dev_saphostexec and most importantly, sapstartsrv.log (Both located under <SAP host agent>/work directory). If no apparent problem is observed in these logs, try increasing their trace level by following the link and recreating the issue - Changing the default trace level of SAP Host Agent

This is important as some of the error messages shown in this note may only appear on an increased trace level.
