Installing Oracle Management Agent in Silent Mode

Configuring Enterprise Manager for Firewalls

Setup the agent host

On the destination host determine the current Oracle BASE directory.

e.g. O:\Oracle

Create a temporary directory, e.g. EM12C, to hold the installation kit and log files.

e.g. O:\Oracle\EM12C

Copy the agent release kit software to the destination host and unzip the file.

i.e. copy 12.1.0.5.0_AgentCore_233.zip to O:\Oracle\EM12C

unzip 12.1.0.5.0_AgentCore_233.zip

This will create the directory O:\Oracle\EM12C\12.1.0.5.0_AgentCore_233

Modify agent installation response file

Inside the expanded release kit directory we will find the file agent.rsp which needs to have the following lines added at the end;

e.g. edit O:\Oracle\EM12C\12.1.0.5.0_AgentCore_233\agent.rsp

AGENT_IMAGE_PATH=O:\Oracle\EM12C\12.1.0.5.0_AgentCore_233\12.1.0.5.0_AgentCore_233.zip

AGENT_REGISTRATION_PASSWORD=

EM_UPLOAD_PORT=4903

OMS_HOST=

REMOTE_SYS_DIR=C:\Windows

LOG_LOC=O:\Oracle\EM12C\logs

ADDITIONAL_PARAMETERS=AGENT_PORT=3872:b_startAgent=true:s_agentHomeName=agent12cR5

Change text in bold as appropriate.

Install agent software only

Open a command window and change the default location to the installation kit directory.

O:\Oracle\EM12C\12.1.0.5.0_AgentCore_233\agent.rsp

Execute the command to install the agent software.

agentDeploy.bat AGENT_BASE_DIR=O:\Oracle\agent12c OMS_HOST=

EM_UPLOAD_PORT=4903 AGENT_REGISTRATION_PASSWORD=

RESPONSE_FILE=O:\Oracle\EM12C\12.1.0.5.0_AgentCore_233\agent.rsp

-softwareOnly

Change text in bold as appropriate.

Modify Firewall properties

The windows firewall settings need to be modified to allow communication between the agent and the oms host.

Start the firewall gui.

Start -> Administrative Tools -> Windows Firewall with Advanced configuration

Modify the settings as shown in the following screenshots.

Right click on “Inbound Rules” and select “New Rule”

 

Enter the port numbers shown

Select

Enter the rule name as “Oracle management Server to Oracle Management agent”

Right click on “Outbound Rules” and select “New Rule”

 

Modify SQLNET.ORA

For security purposes the sqlnet.ora file in use on the agent host may have an entry such as:

TCP.INVITED_NODES = ( node1, node2, node3 )

This entry is used to restrict oracle tcp access to the host; if this entry exists then the grid control host must be added to the invited nodes list; e.g.

TCP.INVITED_NODES = ( node1, node2, node3, OEM )

Configure the agent

Once the firewalls etc have been configured we can reconfigure the agent.

agentDeploy.bat AGENT_BASE_DIR=O:\Oracle\agent12c OMS_HOST=

EM_UPLOAD_PORT=4903 AGENT_REGISTRATION_PASSWORD=

RESPONSE_FILE=O:\Oracle\EM12C\12.1.0.5.0_AgentCore_233\agent.rsp
