Install Oracle OEM agent 13c using EM CLI

In this post we will see how to install OEM agent 13c on any target host.

My OMS server host name : oemhost ( oemhost.oracle.com)
My target host is here : example

Step:1 - Find your supported platform details and OMS version

[oracle@oemhost bin]$ pwd
/u01/app/OEM/Middleware13c/bin
[oracle@oemhost bin]$ ./emcli login -username=gmohapatra
Enter password : 

Login successful
[oracle@oemhost bin]$ ./emcli sync
Synchronized successfully
[oracle@oemhost bin]$ ./emcli get_supported_platforms
-----------------------------------------------
Version = 13.2.0.0.0
 Platform = Linux x86-64
-----------------------------------------------
Version = 13.2.0.0.0
 Platform = Microsoft Windows x64 (64-bit)
-----------------------------------------------
Version = 12.1.0.4.0
 Platform = Linux x86-64
-----------------------------------------------
Platforms list displayed successfully.
[oracle@oemhost bin]$ 


Step:2 - Create agent image. You can create in your OMS and move to target host or you can install emcli client on target host and run same installation steps:

In OMS server downloaded the agent for the platform.

[oracle@oemhost bin]$ ./emcli get_agentimage -destination=/tmp/agentinstaller -platform="Linux x86-64" -version="13.2.0.0.0"

[oracle@oemhost bin]$ 


Step-3: Now let’s scp the software to our target server or Transfer it and unzip it. Then go to the installer location. Then run below command. 

$./agentDeploy.sh AGENT_BASE_DIR=/u01/app/oracle/product/agent13c \
-ignorePrereqs \
-invPtrLoc /u01/app/OraInventory/oraInst.loc  \
AGENT_PORT=3872 \
EM_UPLOAD_PORT=4903 \
OMS_HOST=oemhost.oracle.com \
ORACLE_HOSTNAME=example \
AGENT_INSTANCE_HOME=/u01/app/oracle/product/agent13c/agent_13.2.0.0.0 \ -- optional
AGENT_REGISTRATION_PASSWORD="world123" \
SCRATCHPATH=/home/oracle/tmp

OR

You can create a .rsp ( response file and run like below):

-- see the values set in agent.rsp response file:

$ cat agent.rsp | grep -v ^# | grep -v ^$
OMS_HOST=oemhost.oracle.com
EM_UPLOAD_PORT=4903
AGENT_REGISTRATION_PASSWORD=world123
AGENT_PORT=3872
EM_INSTALL_TYPE="AGENT"

$/u01/app/oracle/product/agent13c/agentDeploy.sh AGENT_BASE_DIR=/u01/app/oracle/product/agent13c RESPONSE_FILE=/u01/app/oracle/product/agent13c/agent.rsp

Note:
If you are getting below error then go with recommended fix:

Error msg:

SEVERE:emctl secure agent command has failed with status=1
Agent configuration has failed
Waiting for agent targets to get promoted...

Fix:

Reset the password of "AGENT_REGISTRATION_PASSWORD"

Setup --> Security --> Registration Passwords --> create

Step:4 - Execute the root.sh as given in the log from # ( root) user

# /u01/app/oracle/product/agent13c/agent_13.2.0.0.0/root.sh

Step-5: Check the agent status now:

[oracle@example bin]$ pwd
/u01/app/oracle/product/agent13c/agent_13.2.0.0.0/bin
[oracle@example bin]$ 
[oracle@example bin]$ ./emctl status agent
