You need to download and apply the agent software from self update then perform the agent deployment. Self update is the only place in EM where you can get the agent binaries.
Refer this - Installing Oracle Management Agent
Thanks for your suggestion.
So is this the only way to get the agent binaries for x86 Platform.
I used the credential and seems that there is no permission over it to download the agent binaries.
Checking for updates at EM Store Error:Server connection failed: 0:IO Error: Status code: 401, Reason: Unauthorized, HTML:<HTML> <HEAD> <meta http-equiv="Content-Type" content="text/html"; charset="UTF-8"> <TITLE>Authentication Required</Title></HEAD> <body text=black bgcolor=white> <h2>HTTP Error 401</h2> <p><strong>Authentication Required</strong></p> </body></html>
FYI... I have used the same credential through which I downloaded the OEM 12c Cloud Software.
