Manual Installation and Upgrade of OEM 13c Agent [Part-1]

Hello viewers, welcome to YouVolve. the database channel to learn and practice oracle and other databases. In this tutorial I am going to demonstrate how to manually install or upgrade an OEM 13c agent.

This topic has two parts. In the Part-1 we install an OEM 13.4 agent manually on a 64 bit Oracle Linux host and in the Part-2 we upgrade the OEM 13.4 agent to version 13.5 manually in a 64 bit Oracle Linux host.

Manual installation of the OEM 13c agent has a prerequisite which are:

- OEM software library must have the required agent software
- The OMS should be up and running
- The agent host should have one of the supported platforms for OEM
- OEM and the target hosts must have network connectivity
- OEM and the target host names should be resolved through DNS
- Minimum 1 GB free space to store the agent software in the target host
- Minimum 2 GB free space to install the agent software in the target host

Manual installation of the agent software involves multiple steps as below:

1- download the agent software to a local file system
2- transfer the agent software to the target host
3- install the agent software to the target host
4- configure the agent software to the target host
5- discover and promote targets
Login to OMS using emcli
=============================================
emcli login -username=sysman
Password: ****

Sync up OMS and repository
=============================================
emcli sync
List available agents software in the library
=============================================
$ emcli get_supported_platforms
Download agent software to a local file system in the OMS host from software library:
==========================================================

mkdir -p /tmp/agnt_inst_134
export unzip_loc=/u01/app/oracle/em135/middleware/bin/unzip
emcli get_agentimage -destination=/tmp/agnt_inst_134 -platform="linux x86-64" -version=13.4.0.0.0 -zip_loc=/u01/app/oracle/em135/middleware/bin/zip

Check its size
=============================================
oracle@adminserver catdb ~$ ls -lrt /tmp/agnt_inst_134
total 913360
-rw-r--r-- 1 oracle oinstall 935272942 jul 11 13:26 13.4.0.0.0_agentcore_226.zip
Transfer the agent software to the /tmp directory in the target host named vmlinux1
=============================================

cd /tmp/agnt_inst_134/
scp /tmp/agnt_inst_134/13.4.0.0.0_agentcore_226.zip vmlinux1:/tmp
oracle@192.168.1.57's password:
13.4.0.0.0_agentcore_226.zip
Agent installation
==================

cd /tmp
unzip 13.4.0.0.0_agentcore_226.zip -d agnt_134_lin64

Create the target folder for the agent base

mkdir -p /u001/oracle/agent13c

Make sure the unzip utility is the one we copied from the middleware home

which unzip
export unzip_loc=/tmp/agnt_134_lin64/unzip

Execute deply command

./agentdeploy.sh agent_base_dir=/u001/oracle/agent13c oms_host=adminserver.manash.hom em_upload_port=4903 agent_registration_password=agent123 oracle_hostname=vmlinux1.oraexpert.org agent_port=3871 -ignoreprereqs

If you want you can also create a response file and put the parameters passed in this command into that response file. then you command will look quite smaller as it will only have two parameters viz agent_base_dir and the response_file parameter that will point to the response file's physical location something like:

./agentdeploy.sh agent_base_dir=/u001/oracle/agent13c response_file=/tmp/agent13c_inst.rsp

Response file agent13c_inst.rsp content:

OMS_HOST=adminserver.manash.hom
EM_UPLOAD_PORT=4903
AGENT_REGISTRATION_PASSWORD=agent123
AGENT_INSTANCE_HOME=/u001/oracle/agent13c/agent_inst
AGENT_PORT=3871
ORACLE_HOSTNAME=vmlinux1.oraexpert.org
b_startAgent=true
EM_INSTALL_TYPE="AGENT"

Check agent status:
========================================

oracle@vmlinux1 orcl1 /tmp/agnt_134_lin64$ cd /u001/oracle/agent13c/agent_13.4.0.0.0/bin
./emctl status agent

List plugins:
========================================
$ ./emctl listplugins agent
$ ./emctl listplugins agent -type all

List targets:
========================================
$ ./emctl config agent listtargets
