Conversion to SAP S/4HANA using SUM: ABAP Systems on UNIX and Linux
Starting or Restarting the Software Update Manager
This section describes how you start the SUM user interface and the SUM back-end
process, or alternatively how you restart SUM if an error, a terminated step, or a system
failure occurred.
Prerequisites
You have met the requirements for the update.
The SAP system and the database have been started.
The SAPCAR version that is referenced in the environment variable
PATH is identical with the one that is located in the kernel directory. In
addition, no reference to any other SAPCAR version must exist in the
PATH variable.
When using Internet Explorer, you have to make sure that the URL relevant for
your system is listed in the “Trusted” security zone. To do so, proceed
as described in the Internet Explorer documentation.
In case of a SUM restart, you have corrected the errors as described in section A.2 Troubleshooting of the SUM
Guide.
