9 Installing Oracle Management Agent Software Now and Configuring 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

• Before You Begin

• Prerequisites

• Installation Procedure

• Configuration Procedure

• After You Install

Overview

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 move your Management Agents from one Enterprise Manager Cloud Control to another, then you must first deinstall those Management Agents and plug-ins, and then redeploy those Management Agents and plug-ins using the new Oracle Management Service. This is typically done when you want to move from an Enterprise Manager Cloud Control in a test environment to an Enterprise Manager Cloud Control in a production environment.

Before You Begin

Before you begin installing a Management Agent, review the points outlined in Before You Begin.

Prerequisites

Before installing the Management Agent, ensure that you meet the prerequisites described in Prerequisites.

Installation Procedure

To install only the software binaries of a Management Agent in silent mode, follow these steps:

1. Follow the Step (1) to Step (7) outlined in Installation Procedure.

2. Invoke the deployment script and pass the response file with the -softwareOnly argument:

   <Software_Extracted_Location>/agentDeploy.sh AGENT_BASE_DIR=<absolute_path_to_agentbasedir> RESPONSE_FILE=<absolute_path_to_responsefile> -softwareOnly

Note:

Do not pass the option -forceConfigure.

Configuration Procedure

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

Note:

The response file you pass here is the same response file you passed in Installation Procedure.

Note:

Do not pass the option -forceConfigure.

Note:

Despite a successful installation, if you see some exceptions in the prerequisite error file, you can ignore the exception trace. This issue might happen when an operation attempts to retrieve an element from a collection using a key that does not exist in that collection. You can ignore this exception.

After You Install

After you install the Management Agent, follow the steps outlined in After You Install.

Note:

If you want to move your Management Agents from one Enterprise Manager Cloud Control to another, then you must first deinstall those Management Agents and plug-ins, and then redeploy those Management Agents and plug-ins using the new Oracle Management Service. This is typically done when you want to move from an Enterprise Manager Cloud Control in a test environment to an Enterprise Manager Cloud Control in a production environment.
