This is a step-by-step procedure to install the latest available release of the Oracle Enterprise Manager 13c (13.2) on Linux 64-bit.

The main installation steps are:

1- Install Oracle Database 12c (  binaries.

2- Create  database using a ready template (to hold the EM’s repository objects).

3- Install the Oracle EM CC


So, let us start.

00 -Software to be downloaded:

1-     Oracle Enterprise Manager Cloud Control 13c Release 2 ( from:


2-   Database Template (with EM repository pre-configured) for Installing Oracle Enterprise Manager Cloud Control 13c Release 2 ( from:


3-     Oracle Database 12c Release 1 ( Enterprise Edition from:


1-   Oracle Database 12c ( Installation

Hardware Specs:

I was lucky to have a server with 256 GB ram and 24 core (48 threads), but at least you should have about 24-32GB ram + 80 GB disk.

O.S is Redhat Linux 6.8

Make a staging area for the database software:
Unzip the database software

Hosts File:                        localhost      localhost.localdomain                  yourHostName   yourHostName.yourDomain

Oracle Installation Prerequisites

You may use the Oracle provided package to do that ( if your server has internet connection)

# yum install oracle-rdbms-server-12cR1-preinstall –y

Or you may check the prerequisites manually as follows:

Add or amend the following lines in the “/etc/sysctl.conf” file.
fs.file-max = 6815744
kernel.sem = 250 32000 100 128

kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65000

Then you may reboot the server or just reload the kernel using:
   /sbin/sysctl –p

Add the following lines to the “/etc/security/limits.conf” file.

oracle   soft   nofile    1024
oracle   hard   nofile    65536
oracle   soft   nproc    16384
oracle   hard   nproc    16384
oracle   soft   stack    10240
oracle   hard   stack    32768

Install the following packages if they are not already present:

yum install binutils -y

yum install compat-libstdc++-33 -y
yum install compat-libstdc++-33.i686 -y

yum install unixODBC-devel –y
yum install zlib-devel –y                           #Linux 7
yum install zlib-devel.i686 –y                      #Linux 7
or you may install them using rpm:
     # rpm –ivh libX11

Users & Groups:

Create the new groups and users.

groupadd -g 1001 oinstall
groupadd -g 1002 dba
groupadd -g 1003 oper
useradd -u 1001 -g oinstall -G dba,oper oracle


Additional Setup

[For Linux 6] Amend the “/etc/security/limits.d/90-nproc.conf” file as described below. See MOS Note [ID 1487773.1]

# Change From
*          soft    nproc    1024

# To:
*             - nproc 16384


Set secure Linux to permissive by editing the “/etc/selinux/config” file as follows.


Once the change is complete, restart the server or run the following command.

# setenforce Permissive

If you have the Linux firewall enabled, you will need to disable.

For Linux 6:
# service iptables stop
# chkconfig iptables off


For Linux 7:
# systemctl stop firewalld
# systemctl disable firewalld


Create the directories in which the Oracle software will be installed:
mkdir -p /u01/app/oracle/product/
chown -R oracle:oinstall /u01
chmod -R 775 /u01


Unless you are working from the console, or using SSH tunnelling, login as root and issue the following command:
 xhost +<machine-name>

Add the following lines at the end of the “/home/oracle/.bash_profile” file:

# Oracle Settings
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=HostName.localdomain
export ORACLE_UNQNAME=emccdb
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/
export ORACLE_SID= emccdb
export PATH=/usr/sbin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

Oracle Binaries Installation:

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable:
  DISPLAY=<machine-name>:0.0; export DISPLAY
Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory:


2- Repository Database Creation Using Template

The database template that you downloaded earlier at step “00” includes all the relevant database settings, but make sure that character set is selected during the creation is “AL32UTF8”.

Unzip the repository template under the ORACLE_HOME.
   cd $ORACLE_HOME/assistants/dbca/templates
   unzip /tmp/

As oracle user, start the Database Configuration Assistant (DBCA) and create a new database using the template:



You may deselect listener creation at this step and create it manually after that (as I received error due to that)


[Optional] Edit the contents of the “/etc/oratab” file, making sure the database can be started and stopped using the dbstart and dbshut commands:


3- EM Cloud Control 13c ( Installation

You don’t need to unzip the EM13c software files, the installer will do that for you, but ensure you have enough space at /tmp (about 10GB)

Make the following directories to hold the management server and agent. There are some restrictions on the possible path lengths, so don’t make the directory structure too deep, especially for Windows installations:

mkdir -p /u01/app/oracle/middleware
mkdir -p /u01/app/oracle/agent

Start the installation by running the "em13200_linux64.bin" file.
 chmod u+x em13200_linux64.bin


I changed the value of the above kernel parameter from 65500 to 65000 and continued.


Now, you can run the EM CC and navigate around successfully:


Also, in this release you will find many plugins installed by default (including Exadata plugin):


In the coming blog, I’ll explain how we can discover one Exadata machine, stay tuned !
