OMS Server Prerequisites (OEM 13cR5)

Repository Database Prerequisites (Oracle 19.23)

 1.Install Required Packages, oracle-database-preinstall-19c package helps to automatically install required packages and configure OS users and groups.

[root@dbsrv09 ~]# yum install oracle-database-preinstall-19c -y

 Installed:

  ksh-20120801-267.0.1.el8.x86_64                    libaio-devel-0.3.112-1.el8.x86_64      libnsl-2.28-251.0.2.el8_10.5.x86_64    lm_sensors-libs-3.4.0-23.20180522git70f7e08.el8.x86_64

  oracle-database-preinstall-19c-1.0-2.el8.x86_64    sysstat-11.7.3-13.0.2.el8_10.x86_64

 Complete!

 

 10. Based on the EM Prerequisite Kit report (prereqResultReport.html), apply the required parameter settings on the repository DB server.

 [oracle@dbsrv01 ~]$ sqlplus / as sysdba

 2. Set Kernel Parameters, Add the port range settings to /etc/sysctl.conf and apply it with sysctl -p

 [root@dbsrv09 ~]# vi /etc/sysctl.conf

net.ipv4.ip_local_port_range = 11000 65000

 [root@dbsrv09 ~]# sysctl -p

 

 11. Restart the repository RAC database to apply the updated parameter changes.

 [oracle@dbsrv01 ~]$ srvctl stop database -db master

[oracle@dbsrv01 ~]$ srvctl start database -db master

 

 3. Set User Limits, Add file and process limits for the oracle user in /etc/security/limits.conf

 [root@dbsrv09 ~]# vi /etc/security/limits.conf

 oracle   soft    nofile     65536

oracle   hard   nofile     65536

oracle   soft    nproc     30000

oracle   hard   nproc     30000

 

 

 4. Stop and disable the firewall service.

 [root@dbsrv09 ~]# systemctl stop  firewalld 

[root@dbsrv09 ~]# systemctl disable firewalld

 

 

 5. Change SELinux mode to disabled in the config file, it requires reboot to take effect.

 [root@dbsrv09 ~]# vi /etc/selinux/config

SELINUX=disabled

 

 

 6. Download Oracle Enterprise Manager 13.5 installer from the official Oracle site, transfer it to the OMS host's /tmp directory and run chmod +x to make it executable.

 [root@dbsrv09 ~]# su - oracle

[oracle@dbsrv09 ~]$ cd /tmp

[oracle@dbsrv09 tmp]$ ls -ltr em13500_linux64*

-rw-r--r-- 1 oracle oinstall 1454982045 Oct 27  2024 em13500_linux64-4.zip

[oracle@dbsrv09 tmp]$ chmod +x em13500_linux64.bin

 

 

 7. Invoke the installer and generate response file for performing a silent installation.

 [oracle@dbsrv09 tmp]$ ./em13500_linux64.bin -J-Djava.io.tmpdir=/opt/tmp -getResponseFileTemplates -outputLoc /tmp/

Launcher log file is /opt/tmp/OraInstall2025-07-04_02-33-51PM/launcher2025-07-04_02-33-51PM.log.

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

Use the following URL to access:

 

        1. Enterprise Manager Cloud Control URL: https://dbsrv09.localdomain:7803/em

        2. Admin Server URL: https://dbsrv09.localdomain:7102/console

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

        1. Admin Server Host Name: dbsrv09.localdomain

        2. Admin Server Port: 7102

You can find the details on ports used by this deployment at : /u01/app/oracle/em13c/oraclehome/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/em13c/gc_inst/em/EMGC_OMS1/sysman/backup on host dbsrv09.localdomain. 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/em13c/oraclehome/bin/emctl exportconfig oms -dir <backup dir>

 Prompt for the allroot.sh

Warning: You must run the following configuration scripts as the "root" user.

  /u01/app/oracle/em13c/oraclehome/allroot.sh

To execute the configuration scripts:

 1. Open a new  terminal window.

 2. Login in as "root".

 3. Run the scripts.
