Regarding the MOS connection did you check note: EM 12c: Unable to complete network operation against My Oracle Support. Please check network connectivity to Oracle Support Site [ID 1376896.1]
Remerber if OMS and Target are on Windows platforms you do have to install Cygwin on the OMS server and on the target server before you can use the Add Host Target wizard, see http://docs.oracle.com/cd/E28271_01/install.1111/e22624/preinstall_req_cygwin_ssh.htm
As an alternative you could use the silent installl way, see http://docs.oracle.com/cd/E25054_01/install.1111/e24089/install_agent_usng_rsp.htm
If you don't have too many Windows servers to monitor I would use this alternative.
As an option try the offline mode:
First set the Cloud Control in Offline Mode:
1. Ensure Cloud Control is set to the offline mode. From the Setup menu, choose Provisioning and Patching>Offline Patching, then change the setting for Connection to Offline.
2. Please follow the section: "Acquiring Management Agent Software in the Offline Mode:" from the following below document:
EM 12c: Acquiring or Updating the Enterprise Manager Cloud Control 220.127.116.11 Management Agent Software Using the Self Update Feature (Doc ID 1369575.1)
Please check the following section in
Enabling Oracle Management Service to Access My Oracle Support
Unless online access to the Internet is strictly forbidden in your environment, Oracle Management Service should be enabled to access My Oracle Support. This access is necessary to enable updates and patches to be downloaded, for example.
At minimum, the following URLs should be made available through the firewall:
About the dontProxyfor Property
When you configure the Oracle Management Service or a Management Agent to use a proxy server, it is important to understand the purpose of the dontProxyFor property, which identifies specific URL domains for which the proxy will not be used.
For example, suppose the following were true:
You have installed the Oracle Management Service and several Management Agents on hosts that are inside the company firewall. These hosts are in the internal .example.com and .example.us.com domains.
You have installed several additional Management Agents on hosts that are outside the firewall. These hosts are installed in the .example.uk domain.
You have configured Enterprise Manager to automatically check for critical software patches on My Oracle Support.
In this scenario, you want the Oracle Management Service to connect directly to the Management Agents inside the firewall without using the proxy server. On the other hand, you want the Oracle Management Service to use the proxy server to contact the Management Agents outside the firewall, as well as the My Oracle Support site, which resides at the following URL:
The following properties will prevent the Oracle Management Service from using the proxy server for connections to the Management Agents inside the firewall. Connections to My Oracle Support and to Management Agents outside the firewall will be routed through the proxy server:
PS: Cygwin has nothing to do with My Oracle Support connection. Cygwin is ONLY required for agent deployment using agent push from OMS.
Yes, but the option to skip these proxies is to go with the silent installation.
The following document explains the steps to perform the agent installation in silent mode:
DOC ID 1360083.1 : How to Install EM 12c Agent using Silent Install Method with Response File
I checked the download site
and the certification matrix no mention of a windows 32bit OEM 12c agent, do you have a link to where I can download this?
If you are using proxy you need to enter correct realm that was used during proxy setting . If you are unsure of that , best way is to take a TCPDUMP & look for realm value in that .
+[root@c-w-pm ~]# tcpdump -vvvs 1500 -A | grep -i auth+
tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 1500 bytes
at....;.HTTP/1.1 407 Proxy Authentication Required
Proxy-Authenticate: BASIC realm="ABC Infrastructure"
Your credentials could not be authenticated: "Credentials are missing.". You will not be permitted access until your credentials can be verified.
using above you will know your realm .
Hi, You can find the info about the Proxy and more detailed errors from the logs @
Log file : EMGC_OMS1-diagnostic.log
This is the log file for the HTTP client/Proxy communication.
Note if you are using NTLM Proxy. It is not supported. You would need to workaround to enable connectivity to My Oracle Support.
In MS PROXY in "Unauthenticated Sites Properties" add these sites
Let us know, what you found and the details.
Filing SR will be helpful to exchange info and files more efficiently. I would request you file an SR and put the details from this thread into it.
You can also mention my name in the SR as the Product Dev. contact.
