Hi ,
In managed system configuration - Enter System parameters , I am giving Load balancer host as http:<managed-system-hostname>.domain_name :8101 which is not connecting ,

but when I simply give <managed-system-hostname> it is connecting with HTTP 200 Ok.

--Telnet from Solution manager to managed system is connecting : telnet <managed-system-hostname>.domain_name 8101
--I checked the profiles parameters of managed system , they are fine.
icm/host_name_full = <managed-system-hostname>.domain_name
SAPLOCALHOSTFULL = <managed-system-hostname>.domain_name
/etc/hosts of Solution manager and managed system have entries for both the systems : IP <hostname>. domain_name <hostname>
When i check D:\usr\sap\<managed_sys>\ASCS01\work\dev_ms , I see full qualified hostname = <managed-system-hostname>, which is WRONG.
How to correct it?
Where from dev_ms is taking only hostname for full qualified domain name ?
Note : In all other systems, dev_ms is showing correct full name.
