Hi,
    I am trying to install the DB2 Administration Server 8.1 in SuSe 8. I 
am running the installation as sudo root and not real root. The 
installation returns with following error

ERROR:An error occurred while updating the configuration parameter 
"DASADM_GRP"
to "db2asgrp" for the DB2 Administration Server. The return value is 
"5001".

ERROR:An error occurred while updating the DB2 Administration Server's
configuration with the specified administration group. Please ensure the
DASADM_GRP setting is correct by using the GET ADMIN CONFIGURATION 
command. To
modify the value of any DB2 Administration Server configuration parameter, 
use
the UPDATE ADMIN CONFIGURATION command.

Configuring the DB2 Administration Server:.......Failure

Can anyone tell me what could be the problem?

thanks
Tulika Agrawal
