Hi Pavan,
As Archie882 have pointed have you reviewed DMGR_HOME/properties/wsadmin.properties file specifically the line
com.ibm.ws.scripting.host
The error says "Unable to find a valid IP for host abc.xyz.com]" have you review if the server "abc.xyz.com" can be resolved?
try doing a nslookup abc.xyz.com (and review /etc/hosts file too) to check if abc.xyz.com can be resolved
Try
wsadmin.sh -conntype SOAP -host IP_DMGR -port 8892
Hope this helps. Tell us if you need more support
Regards
