Hello,

Try this

Stop SAP,Stop DB.Reboot server and launch SUM using SIDADM.

[AtulKumarJain]

Please find the step,you can same check in  SUM guide

********************************************************

To start the Software Update Manager, enter the command <DRIVE>:\<update directory>\STARTUP.BAT

Note

Always start the Software Update Manager from within the directory in which it is located.

Note

If you are running several updates in parallel on the same host, you have to use different port numbers for

each update. When you start the Software Update Manager, specify the port numbers as follows:

○ httpport=<http port number>

○ guiport=<GUI port number>

○ -srvarg=/UseCaseService/abaptoolport=<port number for ABAP update tool>

To start the Software Update Manager GUI, proceed as follows:

Note

This procedure depends on the host on which you are starting the GUI. We recommend that you call the

GUI from an Internet browser.

If, for example, you have to use the SAProuter to pass a firewall, call the GUI by using the Java runtime

environment. In this case, you can specify the required routing string.

If you want to run the Software Update Manager GUI in accessibility mode, see .

Enter the following Internet address:

http://<host name>:4239

Replace <host name> with the name of the host on which the Software Update Manager is running.

b. In the dialog box that appears, choose Run.

Note

If the dialog box does not appear, choose GUI for the Software Update Manager on the update start

page.

Starting the GUI on Windows Hosts

Note

If you have not configured your system differently, you can confirm the default port number 4241 that is

displayed automatically in the dialog box Connection to Server. For more information about the

communication between the back-end processes and the Software Update Manager GUI, see

Communication Between Back-End Processes and GUI [page 41].

a. So that the GUI can also be executed on other hosts, you need an update directory on this host including

the following files:

○ <update directory>\sdt\lib

○ <update directory>\sdt\exe\DSUGui.bat

b. Start the GUI in a command prompt with the command DSUGui.bat.

Enter a user name and a password for the administrator role [page 110].

Note

The password must be at least 6 characters long. Remember this user name and password, as you have to

enter them each time you start the GUI

If still issue persists even after complete restart of system then suggest you to please share results for command

netstat -np TCP | find "4241"

Thanks,

Hi Ajay,

With addition to my previous replies i would suggest you to disable windows firewall & antivirus if any with a complete restart of system.

After that you could initiate startup.bat file & check again on browser for successful connection.

Good luck !!

Hi Ajay,

Have you started SL controller before launching SUM? , if not please start the SL controller and then try to launch the DSUgui.bat

I can see you are starting SUM from DSUGui  (Port 4241), have you tried to open the GUI using the HTTP port???...

Simply call  http://<hostname.fqdn>:4239 from your browser and check if it open SUM.

To add to this, find a file called : sdtdsu.jnlp in your /SUM/sdt/htdoc directory, this file should contain the URL that you need to launch for starting SUM through a browser.

it should contain lines such as:

<?xml version="1.0" encoding="ISO-8859-1"?>
  <jnlp spec="0.2 1.0" href="https://answers.sap.com/sdtdsu.jnlp" codebase="http://<hostname>:4239/">

I mention this, since looking at your thread history, you may have made loads of changes to your Windows hostfile, hence not sure what URL will work.

Additionally try to disable any firewall as well as any antivirus soft on the system before execution.

Hope this will help you.

Good luck !!

Hi Ajay,

Have you maintained host file entries as similar under /etc/hosts file,if not please try to append with

127.0.0.1  localhost.localdomain  localhost
<Server IP>  <Host Name>

After that try to re-execute the process.
