Hello Experts,

I am starting SCC 2.5.0.1 on Windows. I get this error below. How could this problem be resolved?

Thank you for your help!

I have found the root cause of this problem. When I was upgraded to 2.5.0.1, I did not delete the account config file. Now I removed the program with all configs and reinstalled. The problem does not raise any more.

Thank you for your helps so far!

Hi Jozsef,

which file exactly was not deleted before and caused the issue? I like to check if there is a general problem on our side. On Windows, for instance, the /scc_config folder should remain for an upgrade, and the configuration should continue to work after upgraded SCC has been installed to the same location.

What was the previous version of the SCC from which you have started the upgrade?

Thanks,

  Timo

I had the same issue and found a solution. I found that installing the windows installer versions calused this error everybody is experiencing. sapcc-2.5.1-windows-x64.msi .

Just uninstall this completely. Delete the directory in which it was installed.

Next unzip the developer edition provided as a zip file - sapcc-2.5.1-windows-x64.zip  This file can be found at tools.hana.ondemand.com -> cloud .

Hi Sumit,

actually, the upgrade should work without any issue. In case a situation occurs like ecxperienced by Jozsef or you, there needs to be a cause that needs to be identified and a fix provided so that it cannot happen. Using the ZIP does only help in a development environment, but not if you like to use the SCC productively, because then you'd need the capability of the Windows service.

So, if you have more details - please let us know. If possible via ticket for BC-MID-SCC.

Hi Timo,

I upgraded from SCC 2.4.3 to SCC 2.5.0.1.

I don't know which file caused this behaviour because I deleted the SAP (root)folder with all stuff within.

Jozsef

Hi Jozsef,

a first guess would be: is port 8443 blocked by another program? If you open a command window (with admin privileges) and type the command

netstat -abo

you should see a list of open network ports including the executable name and the process ID of the program that opened a port. If a different program is blocking 8443, you could either stop that program or change the configuration of the SCC to start on a different port, e.g. 7443 or 9443. The SCC installation documentation has a section about how to change the port number.

Hi Ulrich,

thank you for this suggestion but port 8443 is not blocked.

Hi Jozsef,

what Windows version and Java SDK + version do you use? Can you please check if it matches the system requirements described here?

Best regards,

Hi Timo,

I am using the latest version of SCC (2.5.0.1) and SAPJVM (7.1.024) downloaded from here, on Win7.

I also set JAVA_HOME and PATH to the right paths:

C:\SAP\scc20>set JAVA_HOME="C:\dev\sapjvm_7"

C:\SAP\scc20>set PATH=%JAVA_HOME%\bin;%PATH%

These seem to be OK. Any other idea?

Kind regards,

Jozsef
