Oracle Enterprise Manager Cloud Control 24ai (24.1) Silent Installation on Oracle Linux 8

On this article we are going to do a silent install of Oracle Enterprise Manager Clod Control 24ai on a Oracle Linux 8 server.
First we need an oracle DB where the repository will run. You can use a non-cdb, but since starting from 26ai, CBD/PDB is a must, we are going to use a 19c PDB.
So lets first install RDBMS software and create a db.

We are going to start with an Oracle Linux server with a few installs:

[root@olinux8oem ~]# dnf -y install oracle-database-preinstall-19c
[root@olinux8oem ~]# yum install policycoreutils-python-utils
[root@olinux8oem ~]# dnf install perl
[root@olinux8oem ~]# yum install chkconfig
[root@olinux8oem ~]# yum update -y

[root@olinux8oem ~]# reboot
[root@olinux8oem ~]# uname -a
Linux olinux8oem 5.15.0-317.197.5.1.el8uek.x86_64 #2 SMP Fri Feb 13 02:40:51 PST 2026 x86_64 x86_64 x86_64 GNU/Linux
[root@olinux8oem ~]#

Install 19c RDBMS software and apply latest patch. (for now will work with 19.26 Patch… so not the latest.)

[oracle@olinux8oem ~]$ cd /u01/app/oracle/product/19c/db_home1/
[oracle@olinux8oem db_home1]$ cp -p /u01/installs/LINUX.X64_193000_db_home.zip .

[oracle@olinux8oem db_home1]$ cp -p /u01/installs/19.26_OPATCH_p6880880_190000_Linux-x86-64.zip .
[oracle@olinux8oem db_home1]$ unzip -q 19.26_OPATCH_p6880880_190000_Linux-x86-64.zip
[oracle@olinux8oem db_home1]$ rm *zip

See the following for information pertaining to your Enterprise Manager installation:


Use the following URL to access:

        1. Enterprise Manager Cloud Control URL: https://olinux8oem:7803/em
        2. Admin Server URL: https://olinux8oem:7102/console

The following details need to be provided while installing an additional OMS:

        1. Admin Server Host Name: olinux8oem
        2. Admin Server Port: 7102

You can find the details on ports used by this deployment at : /u01/app/oracle/middleware/oms_home/install/portlist.ini


 NOTE:
 An encryption key has been generated to encrypt sensitive data in the Management Repository. If this key is lost, all encrypted data in the Repository becomes unusable.

 A backup of the OMS configuration is available in /u01/app/oracle/gc_inst/em/EMGC_OMS1/sysman/backup on host olinux8oem. See Cloud Control Administrators Guide for details on how to back up and recover an OMS.

 NOTE: This backup is valid only for the initial OMS configuration. For example, it will not reflect plug-ins installed later, topology changes like the addition of a load balancer, or changes to other properties made using emctl or emcli. Backups should be created on a regular basis to ensure they capture the current OMS configuration. Use the following command to backup the OMS configuration:
/u01/app/oracle/middleware/oms_home//bin/emctl exportconfig oms -dir <backup dir>

Now, connect to https://olinux8oem:7803/em with sysman user and select how you want you home page to look (you can change going to top right -> SYSMAN -> welcome page)

Perfect, you have now Oracle Enterprise Manager up and running, and monitoring… basically nothing, yet!

On the old world, you needed to install an agent on each of the server, but on 24ai they introduced another way of going, it is via Remote Agent, on which a single agent on a server and this monitors remote hosts targets. Since this is just a test for my lab, I’m going to do it the old way…

Click the 3 lines on the top left -> Setup -> Add Target -> Add Targets Manually, then Install Agent on Host

Make sure host to monitor is under /etc/hosts, on this case server name is olinux8:

Next.

Fill “Installation Base Directory” and “Instance Directory“:

Populate Named Credential and Root Credential:

Next

Deploy Agent and wait for deployment….

I had to install a few packages on the remote host since prerequisites completed with warnings.

dnf install -y make
dnf install -y binutils
dnf install -y gcc
dnf install -y libaio
dnf install -y libstdc++
dnf install -y sysstat
dnf install -y glibc-devel
dnf install -y glibc-common
dnf install -y libXtst
dnf install -y libnsl

Retry and wait (you might need to cancel and re-try the deployment….)

Now, go to Targets -> Hosts:

Now, how to bring the DB targets into monitoring? go to Targets -> All Targets. At the bottom there is “Discovered Targets” (click at the number)

Here we can see the Agent on the host discovered the targets. Select all the targets from the desired Host with the same “Target Type” and Promote. On this case we are only doing the ASM instance, HAS, Listener and DB.

Repeat the same for all target types and when done, go to Targets -> All Targets and select what you want to check:

Install and monitoring is all done, but OEM autostartup will fail unless DB is up and running, so let’s do a controlled startup.

Comment out the homes inside this file so no automatic startup is attempted:

[oracle@olinux8oem ~]$ cat /etc/oragchomelist

#/u01/app/oracle/agent/agent_24.1.0.0.0:/u01/app/oracle/agent/agent_inst
[oracle@olinux8oem ~]$

Create this startup script:

[oracle@olinux8oem scripts]$ cat /home/oracle/scripts/OEM-full-stack-startup.sh
#!/bin/bash
export ORACLE_HOME=/u01/app/oracle/product/19c/db_home1

echo "Starting OMS resources... :"

Create this shutdown script:

#!/bin/bash
export ORACLE_HOME=/u01/app/oracle/product/19c/db_home1

echo "Stopping AGENT resources... :"
$AGENT_HOME/bin/emctl stop agent

echo "Stopping DB resources... :"
$ORACLE_HOME/bin/dbshut $ORACLE_HOME

[oracle@olinux8oem scripts]$

You can add these scripts to the normal startup/shutdown server startup, or run manually.

That’s it! Comparing this vs old versions, this is way easier.
