Step 02 - Add the '/etc/hosts' entry of the EM server to all the target servers.

Entry on all '/etc/hosts' of the target servers:

# EM_24ai
<ip-of-EM-server> <hostname-of-EM-server> <hostname-alias>

Step 03 - Add the '/etc/hosts' entry of the target servers to the EM server.

Entry on EM server:

#Server 1
<ip-of-server1> <hostname-of-server1> <hostname-alias>
#Server 2
<ip-of-server2> <hostname-of-server2> <hostname-alias>
#Server 3
<ip-of-server3> <hostname-of-server3> <hostname-alias>
#Server 4
<ip-of-server4> <hostname-of-server4> <hostname-alias>

Step 03 - Create a directory names EM_24AI_AGENT on all target servers. Give correct permission and ownership (to oracle user)

mkdir -p /u01/app/EM_24AI_Agent
chown oracle:oinstall /u01/app/EM_24AI_Agent

Step 04 - Log in to the Console and start configuring the agents

1. Navigate to Setup > Add Target > Add Targets Manually


2. Select Install Agent on Host


3. Select Add and enter the correct details of the target server

6. Add the correct entries




7. Select Continue all hosts from the Continue drop down



8. Run the root scripts

9. The agents are successfully configured and the hosts are successfully added to the EM for monitoring.
