Dear SuSE Colleagues, I'm finding troubles with zypper.
a) I'm a new user of one SuSE trial from IBM with DB2 installed in it, every thing is working fine, and I manage the system on command line;
b) I would like to install YAST, therefore I checked the installed repositories:
zypper lr
No repositories defined. Use the 'zypper addrepo' command to add one or more repositories.
c) and then
zypper ar
Cant open /var/run/ in mode w

uname -a
Linux db2v10 3.0.26-0.7-default #1 SMP Tue Apr 17 10:27:57 UTC 2012 (3829766) x86_64 x86_64 x86_64 GNU/Linux

db2v10:/etc # cat SuSE-release
SUSE Linux Enterprise Server 11 (x86_64)

Really I'm not able to understand the message, that appears unknown on google and in SuSE Forums - in a couple hours to navigate - as well.
Now, I would like to get support for the zypper failure and the yast installation.
And possibly, to understand the logic of the pid file.
Thanks for the cooperation.
