Deploying OEM 12c Management agents

OEM 12c agents can be deployed using a few options and here's the simple procedure for the 'silent install' option using the response file method.

• Extract the Management agent software from the OMS for your platform.

                (asssuming the OMS_HOME is "/u01/app/middleware/oms")

             /u01/app/middleware/oms/bin/emcli login -username=sysman
             /u01/app/middleware/oms/bin/emcli sync
             /u01/app/middleware/oms/bin/emcli get_supported_platforms

Here's the command used to extract the binaries for Linux x86_64 bit (by default OMS host will have the agent binaries for the platform on which OMS is rnning)

/u01/app/middleware/oms/bin/emcli get_agentimage -destination="/tmp/agent_Linux_x86_64" -platform="Linux x86-64" -version=12.1.0.1.0

This will generate the "12.1.0.1.0_AgentCore_226.zip" zip file under /tmp.

• Copy this zip file to a temporary location to the Host where the agent need to be installed.
• unzip the file and update the response file as below.

               OMS_HOST="OMS Server"
               EM_UPLOAD_PORT="4889"
               AGENT_REGISTRATION_PASSWORD="xxxxxx"
               #AGENT_INSTANCE_HOME=
               AGENT_PORT=3872
               b_startAgent=true
               ORACLE_HOSTNAME="Host where Management Agent need to be installed"
               s_agentHomeName="agent12c"

• Deploy the agent as below

/tmp/agentDeploy.sh AGENT_BASE_DIR=/u00/app/oracle/product/11.2.0/agent12c RESPONSE_FILE=/tmp/agent.rsp

Pls ensure AGENT_BASE_DIR is NOT a parent directory of any other Oracle software installation directories. This will cause serious issues if you try to uninstall in future for any reason as the entire 'agent_base_dir' directory will be removed after the deinstallation of the agent software.

Once the agent installation is complete, it'll prompt you to run the root.sh and that'll complete the agent setup and the uploads will commence immediately.
