Em12c:Silent Oracle Management agent Installation

This Post would describe how to install Oracle Management Agent 12c in silent mode. We need to download the agent software which can be done using emcli utility which is present on OMS host.Login to OMS host and execute emcli utility as mentioned below

[[email protected]]~/Middleware/oms/bin% emcli login -username=sysman
Enter password 

Login successful

We need to now syncronize EMCLI

[[email protected]]~/Middleware/oms/bin% emcli sync
Synchronized successfully

Following command gets list of agent software present on grid control

[[email protected]]~/Middleware/oms/bin% emcli get_supported_platforms
Getting list of platforms ...
Check the logs at /home/oracle/Middleware/oms/bin/agent.log
About to access self-update code path to retrieve the platforms list..
Getting Platforms list  ...
-----------------------------------------------
Version = 12.1.0.1.0
 Platform = Linux x86-64
-----------------------------------------------
Platforms list displayed successfully.

Since this is a new Grid installation on Linux x86-64 we get only 1 agent software. If you need to install agent on different platform say Solaris, then you need to download software using self update option.
Note that you will have to pass your My oracle support credentials while configuring self-update.

Since our target host is also Linux x86-64 we can proceed. In below example we have specified that our 12.1.0.1.0 agent software should be placed in /tmp for Linux x86-64 platform

[[email protected]]~/Middleware/oms/bin% ./emcli get_agentimage -destination=/tmp -platform="Linux x86-64" -version=12.1.0.1.0
Platform:Linux x86-64
Destination:/tmp

[[email protected]]~/Middleware/oms/bin% ls -l /tmp/12.1.0.1.0_AgentCore_226.zip

You should copy this file to the target host and unzip it.

To perform installation , we need to use agentDeploy.sh script. You can either use agent.rsp in unzipped directory or pass parameters at command line

AGENT_BASE_DIR ->Location where Agent software will be installed
OMS_HOST -->OMS host name
EM_UPLOAD_PORT -->Agent upload port. Script will try both http/https port.
AGENT_REGISTRATION_PASSWORD -->Password for secure registration with OMS

e.g
agentDeploy.sh AGENT_BASE_DIR=/home/oracle/agent12c OMS_HOST=oradbdev04 EM_UPLOAD_PORT=4900 AGENT_REGISTRATION_PASSWORD=oracle123

You will be prompted to run root.sh as below

-bash-3.2$ sudo /home/oracle/agent12c/core/12.1.0.1.0/root.sh
Password:
Finished product-specific root actions.
/etc exist

Creating /etc/oragchomelist file...
Finished product-specific root actions.

Verify following commands are working properly

cd $AGENT_HOME/core/12.1.0.1.0/bin
./emctl status agent
./emctl upload agent

$ ./emctl upload agent
Oracle Enterprise Manager 12c Cloud Control 12.1.0.1.0

Next step is to discover the targets. You can either manually add them or use automated discovery of new Oracle targets on machines which already have agent installed. Refer to EM12c:Automated discovery of Targets for automatic discovery and target configuration.

  1. > agentDeploy.sh AGENT_BASE_DIR=/home/oracle/agent12c OMS_HOST=oradbdev04 EM_UPLOAD_PORT=4900 AGENT_REGISTRATION_PASSWORD=oracle123

    I have some questions:

    1- where I can find the agentDeploy.sh script?
    2- OMS_HOST is the host where em12c is installed or where the agent will be installed?
    3- How about RAC 11gR2 (11.2.0.3) How I can add the RAC database to be monitored by em12c?

    Thanks,
    Mek

  2. > EM_UPLOAD_PORT=4900

    In the case of RAC nodes, the EM_UPLOAD_PORT number can be the same for each node of RAC or must be different? and why you have chosen 4900 and not other port number? what are the ports range we can use?

    Thanks,
    Mek
