Oracle Management Server (OMS)

You can search My Oracle Support (formerly Metalink) for Oracle software patches and patchsets, and download these patches or patch sets to an appropriate location in the OMS Oracle home of Enterprise Manager.

The direction of the arrows specify the direction of ports.

• Port 1159, 4898-4989 specify that 1159 is the default. If this port is not available, the management Service will search in the range that is specified.
• To clone between two target hosts separated by a firewall, the agents will need to communicate to each other on the agent ports.
• The initiating agent will make the call.

Configuring the Firewall to Allow Incoming Management Data from the Management Agents

While the Management Agents in your environment must contact the Management Agents on your managed hosts, the Management Service must also be able to receive upload data from the Management Agents. If the Management Service is behind a firewall, you must configure the firewall to allow the Management Agents to upload data on the upload port.

See:

http://www.scribd.com/doc/49302050/Oracle-Enterprise-Manager procedures and port assignments.

After you determine the port number assigned to the Management Service upload port, you must then configure the firewall to allow incoming HTTP or HTTPS traffic (depending upon whether or not you have enabled Enterprise Manager Framework Security) on that port.

• SSH (Secure Shell) Setup
• SSH Setup is the connectivity that is established between the host running Oracle
• Management Service and the host where the Management Agent needs to be installed.
• This is primarily required for the Agent Deploy application to install Management.

Agents over HTTP on remote hosts.

The Agent Deploy application is an application that is part of the Enterprise Manager Grid Control console. It is used for deploying Management Agents in your environment using an interactive user interface. The installation of a Management Agent from the source host to the remote target host happens over HTTP, and for this communication to happen over HTTP, an SSH setup is required between the two hosts. This also helps to avoid SSH authentication calls during future Agent Deploy operations.

Firewalls between the Management Service and the Management Repository

Secure connections between the Management Service and the Management Repository are performed using features of Oracle Advanced Security. As a result, if the Management Service and the Management Repository are separated by a firewall, you must configure the firewall to allow Oracle Net firewall proxy access.

SSH Setup is required if you are installing a Management Agent using Enterprise Manager 10g Grid Control Release 3 (10.2.0.3) or higher, but you do not have to set it up manually.

In Enterprise Manager 10g Grid Control Release 3 (10.2.0.3) or higher, the Agent Deploy application sets up and drops the SSH connectivity automatically, but if the Management Agent is going to be on a Microsoft Windows operating systems, then you need to install and configure Cygwin on that host.

Therefore, if you are installing a Management Agent using Enterprise Manager 10g Grid Control Release 3 (10.2.0.3) or higher, then you do not have to set up the SSH connectivity manually, but have to install Cygwin for Microsoft Windows hosts. So you do not have to run the SSH script (sshUserSetup.ssh/sshUserSetupNT.ssh, sshConnectivity.sh) before starting with the Agent Deploy application.

This site is your central information source for all Enterprise Manager extensibility information. Partners can build plug-ins for their products, and post the plug-ins there. Customers who want to monitor their custom applications can download documentation and tutorials on how to build custom plug-ins. In addition to tutorials and the latest documentation, you can download ready-to-use Management Plug-ins developed by Oracle as well as third-party integrators. Because this list is continually being updated, you should check the Extensions Exchange site regularly.
