Installation of Oracle Enterprise Manager 12c cloud control on Linux

This article will demonstrate step-by-step procedure to Install Oracle Enterprise Manager Cloud Control 12c software on Linux. The Installation is performed on Oracle Enterprise Linux 5.6 (32-bit).

Oracle EM 12 c cloud control is the next generation system management and monitoring software.

This software is certified on Oracle enterprise Linux 4 and 5 only. Its still not certified on oracle Linux 6.

Software's used:

1) Oracle Enterprise Linux 5.6
2) Oracle Database 11.2.0.1
3) Oracle Enterprise manager 12c cloud control

The complete Installation and configuration is performed in three steps:

step 1 : Perform all OS related per-requisites
step 2 : Install and configure database
step 3 : Install Oracle 12c cloud control


step 1 : Perform all OS related per-requisites

-> Hardware requirement:

CPU - 2 cores
RAM - 4 GB Min.
HDD Space - 8 GB required

I've used one virtual machine with single core CPU, 4 GB RAM and 20 GB HDD space.


-> Os package requirement:

The below listed are the required rpms.

make-3.81
binutils-2.17.50.0.6
gcc-4.1.1

-> create OS group and User:

ora11g is the user who is the owner of oracle database as well as EM 12c cloud software it belongs to dba group

[root@oracloud1 ~]# groupadd dba
[root@oracloud1 ~]# useradd -g dba ora11g
[root@oracloud1 ~]# passwd ora11g
Changing password for user ora11g.
New UNIX password: 
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password: 
passwd: all authentication tokens updated successfully

-> create directories for Installation:

/u01/oradb --> Oracle database
/u01/em12_home --> Oracle EM 12c cloud control

step 3 : Install Oracle 12c cloud control

- I've extracted the sw zip files in windows and copied it to the linux box as i faced problems with installation when i unzipped it on the server

- Set the proper display variable and begin with the Installation

- screens for Installation








- here it failed for package compat-db, after Instillation of this package the pre-req check was successfull



- swap space is almost nearest value (4094 MB) as recommended (4096 MB) so ignored







- Here /u01/em12_home/oracle is actual value


































Done with the Installation.

All comments/suggestion/issues with configuration of EM 12c cloud control are appreciated


My next articles related to EM 12c cloud control:

1) Installation of EM12c on Solaris sparc and Solaris X86-64
2) upgrading EM12c from 10g/11g grid control.
2) Deployment and management of agent on targets
3) Managing RAC databases with EM 12c

thanks and regards,
