Thanks Thomas for your reply.
If I understand correctly, why can't i just create a symlink?
ln -s /usr/sap/HDB /usr/sap/HDB/HDB
Re-installation was successful with this symlink. (but the number of instances was not set to 1 after installation, I had to do this manually)
From the server it looks good now, BUT xs command-line tool is not working any more. Of course certificate is untrusted but after login I always get
FAILED: Could not decode access token: Bad credentials.
I also double checked the credentials, but if I really input a wrong password I get a different error:
Authentication failed: Name or password mismatch
At first I thought it might be a mismatch between xs tool (1.0.9) and xs controller (1.0.13) but I get the same error on the instance itself with command-line tool 1.0.9...
Do you have any idea what might be the cause for the access token issue? Otherwise I will probably re-install XSA again tomorrow...
Best Regards,
Fabian
