As of late, I’ve had to do a few Windows OS Agent Deployments. As we all know, if you want to auto deploy to a Windows OS, you need to have CygWin installed (on each target host) first.The alternative, via Silent Install, is illustrated by my good friend Bobby Curtis here. However, for large scale quicker deployments, I came up with an a solution which worked quite well.Assuming you have already download the agent binaries from the OMS server, copy them to a centralized location accessible to all target hosts.In my case, I used \\slave\software\oracle\oem\12.1.0.3.0\agent.

The important thing here is the content of the agent.rsp file. Mine looks like this. I did not keep the ORACLE_HOSTNAME parameter within the response file (agent.rsp).

EM_INSTALL_TYPE="AGENT"

I then created a wrapper install script. Since I was deploying on windows, the script looked like

c:\> view DeployTheAgent.bat \\slave\software\oracle\oem\12.1.0.3.0\agent\agentDeploy.bat AGENT_BASE_DIR=D:\Oracle\app\product\12.1 RESPONSE_FILE=\\slave\software\oracle\oem\12.1.0.3.0\agent\agent.rsp ORACLE_HOSTNAME=%COMPUTERNAME%.%USERDNSDOMAIN%

The linux version of this might look something like

$ cat DeployTheAgent.sh \\slave\software\oracle\oem\12.1.0.3.0\agent\agentDeploy.sh AGENT_BASE_DIR=/u01/app/oracle/product/12.1 RESPONSE_FILE=\\agent.rsp ORACLE_HOSTNAME=hostname.domainname

From here, its a simple as invoking the script from the target host:

c:\>\\slave\software\oracle\oem\12.1.0.3.0\agent\DeployTheAgent.bat
\\slave\software\oracle\oem\12.1.0.3.0\agent\agentDeploy.bat AGENT_BASE_DIR=D:\Oracle\app\product\12.1 RESPONSE_FILE=\\slave\software\oracle\oem\12.1.0.3.0\agent\agent.rsp ORACLE_HOSTNAME=javelin.missile.com

The installer takes a few minutes and I’d rather not bore you with the contents of the log files. You know what you are doing :)So, for any new target host, simply invoke the DeployAgent.bat or DeployAgent.sh script and relax! Assuming that your paths are correct and, network ports are accessible, the installation should go through without any glitches.
