10 Installing the Oracle Management Agent Software Now and Configuring It Later
This chapter explains how you can install only the software binaries of Oracle Management Agent (Management Agent) at one point and configure the installation at a later stage. In particular, this chapter covers the following:
Overview of Installing a Management Agent and Configuring It Later
You can choose to install only the software binaries of the Management Agent at one point and configure it at a later stage to work with the associated Oracle Management Service (OMS). This approach enables you to divide the installation process into two phases, mainly the installation phase and the configuration phase.
During the installation phase, you invoke the agentDeploy.sh script passing the -softwareOnly argument to copy the software binaries and create an Oracle home for the Management Agent. During the configuration phase, you invoke the same script passing -configOnly to configure the software binaries.
Understandably, the installation phase takes much lesser time compared to the configuration phase because the installation phase involves only copying of binaries. This helps you plan your installation according to the time and priorities you have.
Note:
This installation type is available only in silent mode.
Note:
If you want to repoint your existing Management Agents to a new Oracle Management Service (OMS), then you must first deinstall those Management Agents and plug-ins, and then redeploy those Management Agents and plug-ins using the new OMS. This is typically done when you want to move from an Enterprise Manager Cloud Control system in a test environment to an Enterprise Manager Cloud Control system in a production environment.
When you repoint your existing Management Agents to a new OMS, you cannot move the targets monitored by the Management Agents, the target history, and the Management Agent history. The monitored targets and the history data is lost.
Before You Begin Installing a Management Agent
Before you begin installing a Management Agent, review the points outlined in Before You Begin Installing a Management Agent in Silent Mode.
Prerequisites for Installing a Management Agent
Before installing the Management Agent, ensure that you meet the prerequisites described in Prerequisites for Installing a Management Agent in Silent Mode.
Installing Only the Management Agent Software Binaries
To install only the software binaries of a Management Agent in silent mode, follow one of the procedures mentioned in Installing a Management Agent Using the agentDeploy Script. While invoking the deployment script, ensure that you pass the -softwareOnly option:
<Software_Extracted_Location>/agentDeploy.sh AGENT_BASE_DIR=<absolute_path_to_agentbasedir> RESPONSE_FILE=<absolute_path_to_responsefile> -softwareOnly
For example, /tmp/agtImg/agentDeploy.sh AGENT_BASE_DIR=//u01/software/em13c/agentbasedir RESPONSE_FILE=/tmp/agtImg/agent.rsp -softwareOnly
If the Management Agent is installed successfully, a message mentioning so is displayed on the command line.
Note:
Do not pass the option -forceConfigure.
Configuring the Management Agent Software Binaries
To configure the software binaries of a Management Agent in silent mode, invoke the deployment script with the following options from the Management Agent home:
$<AGENT_HOME>/sysman/install/agentDeploy.sh AGENT_BASE_DIR=<absolute_path_to_agentbasedir> RESPONSE_FILE=<absolute_path_to_responsefile> -configOnly
For example,
/u01/software/em13c/agentbasedir/agent_13.5.0.0.0/sysman/install/agentDeploy.sh
AGENT_BASE_DIR=/u01/software/em13c/agentbasedir
RESPONSE_FILE=/tmp/agtImg/agent.rsp -configOnly
If the Management Agent is installed successfully, a message mentioning so is displayed on the command line.
Note:
-
The response file you pass here is the same response file you passed in Installing Only the Management Agent Software Binaries.
-
Do not pass the option
-forceConfigure.
After Installing a Management Agent
After you install the Management Agent, follow the steps outlined in After Installing a Management Agent in Silent Mode.
