Cause

The issue is due to missing hosts file entry in hosts file of OMS machine.
Also the output of following commands show that the OMS is up and accessible:

D:\oracle\Middleware\oms11g\BIN>emctl status oms -details

Oracle Enterprise Manager 11g Release 1 Grid Control

Console Server Host : test.com
HTTP Console Port : 7788
HTTPS Console Port : 7799
HTTP Upload Port : 4889
HTTPS Upload Port : 1159
SLB or virtual hostname: test.com
Agent Upload is unlocked.
OMS Console is unlocked.
Active CA ID: 1

Solution

* Add the following entries in hosts file, in following format:

IPAddress hostname.domainname shortname

* Now restart the OMS by issuing following command from OMS_HOME/bin:

emctl stop oms -all
emctl start oms

* Now check whether the following URL works:

https://OMSname:port/em

Once the above URL is accessible, try to secure the agent.
