TL;DR

There is an automated Vagrant build for Cloud Control 13c available here.

Software

Download the following software:

OS Installation

Install Oracle Linux (OL) in the same way you would for a regular Oracle Database installation. You can see examples of this type of installation below. Remember to check database installation article (listed below) for the specific package group selection. These Linux installations articles are generic, not specific for Cloud Control.

During this installation I used a virtual machine with 6G RAM (more would be better) and 100G disk space. The swap size was set at 8G, the firewall was disabled and SELinux was set to permissive.

Database Installation (Software-Only)

The Cloud Control 13.3 installation can use database versions 12.1.0.2, 12.2.0.1 or 18.x for the repository. You should use apply the latest patchset, but the installation will work with the base release. For this installation you will need 12.2.0.1 for the repository database, but the same instructions work for 18c, so use the installation instructions from this article.

Alternatively, just do a silent installation from the "oracle" user, and run the root scripts when prompted.

# 12cR2
unzip linuxx64_12201_database.zip
cd database

# 18c
cd $ORACLE_HOME
unzip LINUX.X64_180000_db_home.zip

The installation documentation says the following packages are necessary for the cloud control installation. If you have performed the database installation as described in one of the above articles, most of these prerequisites will already have been met.

# OL6 and OL7
yum install make -y
yum install binutils -y
yum install gcc -y
yum install libaio -y
yum install glibc-common -y
yum install libstdc++ -y
yum install sysstat -y
yum install glibc -y
yum install glibc-devel.i686 -y
yum install glibc-devel -y
yum install libXtst -y

The database software installation is now complete.

Repository Database Creation

Create a database to hold the repository.

As mentioned above, database version 12.2.0.1 Enterprise Edition is used for this installation, but 12.1.0.2 and 18c are also supported.
You can use a Non-CDB database, or a PDB. Here we are using a CDB called "emcdb" and a PDB called "emrep".
Character set AL32UTF8.
Set "_allow_insert_with_update_check"=true.
There are some minimum recommended settings listed in the example database creation below.

You can create the database using the DBCA in interactive mode, but it's easier to do it silently.

lsnrctl start

mkdir -p /u01/oradata

dbca -silent -createDatabase                                                    \
     -templateName General_Purpose.dbc                                          \
     -gdbname emcdb -sid emcdb -responseFile NO_VALUE                           \
     -characterSet AL32UTF8                                                     \

     -createAsContainerDatabase true                                            \
     -numberOfPDBs 1                                                            \
     -pdbName emrep                                                             \

     -storageType FS                                                            \
     -datafileDestination /u01/oradata                                          \
     -redoLogFileSize 50                                                        \
     -emConfiguration NONE                                                      \

You now have a database for use as the repository.

Cloud Control 13c Installation

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 "em13300_linux64.bin" file.

$ chmod u+x em13300_linux64.bin
$ ./em13300_linux64.bin

If you wish to receive support information, enter the required details, or uncheck the security updates checkbox and click the "Next" button. Click the "Yes" button the subsequent warning dialog.

My Oracle Support Details

If you wish to check for updates, enter the required details, or check the "Skip" option and click the "Next" button.

Software Updates

If you have performed the prerequisites as described, the installation should pass all prerequisite checks. Click the "Next" button. I got warnings as I was using a VM with less than the recommended memory. I ignored both by clicking the "Ignore" button, then the "Next" button.

Prerequisite Checks

Select the "Create a new Enterprise Manager System" and "Simple" options, then click the "Next" button.

Install Types

Enter the middleware and agent locations, then click the "Next" button.

Installation Details

Enter the administrator password and database repository details, then click the "Next" button. If you are using the Multitenant template the PDB name will be "emrep". If your database uses a domain, the PDB name will be "emrep.your.domain".

Configuration Details

Click the "Yes" button to allow the installer to fix any errors.

Fixable Errors

Click the "OK" button to accept the warnings. If this is a real installation you should make sure all minimum settings are met.

Warnings

Enter a location for the software library. If you are using multiple management servers, you will need to configure shared storage for BI Publisher. For this installation I unchecked the "Configure a Shared Location for Oracle BI Publisher" option, but left the "Enable Oracle BI Publisher" option checked. Click the "Next" button.

Shared Location Details

If you are happy with the review information, click the "Install" button.

Review

Wait while the installation and configuration take place.

Installation Progress Details

When prompted, run the root scripts, then click the "OK" button.

Root Scripts

Make note of the URLs, then click the "Close" button to exit the installer. A copy of this information is available in the "/u01/app/oracle/middleware/install/setupinfo.txt" file.

Finish

The login screen is available from a browser using the URL provided in the previous screen ("https://ol7-emcc.localdomain:7803/em"). Log in with the username "sysman" and the password you specified during your installation.

Once logged in, you are presented with a with the "Accessibility Preference" screen. Click the "Save and Continue" button and you are presented with the the "License Agreement" screen. Click the "I Accept" button and you are presented with the homepage selector screen. On the right side of the screen it lists the post-installation setup tasks you need to work through. I have these documented in a separate article. Select the desired homepage (I chose Summary).

Homepage Selector

You are presented with the selected screen as the console homepage. it might take some time for all of the targets to be recognised as up.

Console

Startup/Shutdown

Cloud Control is set to auto-start using the "gcstartup" service. The "/etc/oragchomelist" file contains the items that will be started by the system.

/u01/app/oracle/middleware
/u01/app/oracle/agent/agent_13.3.0.0.0:/u01/app/oracle/agent/agent_inst

On a simple installation the default auto-start will cause a problem as Cloud Control will attempt to start before the database has started. The service can be disabled by commenting out (using #) all the contents of the "/etc/oragchomelist" file to prevent the auto-start and use start/stop scripts described below.

If the start/stop needs to be automated, you can do it in the usual way using Linux service that calls your start/stop scripts that include the database management.

Use the following commands to turn on all components installed by this article.

#!/bin/bash
export ORACLE_HOME=/u01/app/oracle/product/12.2.0.1/db_1
export OMS_HOME=/u01/app/oracle/middleware
export AGENT_HOME=/u01/app/oracle/agent/agent_inst

# Start everything
$ORACLE_HOME/bin/dbstart $ORACLE_HOME

$OMS_HOME/bin/emctl start oms

$AGENT_HOME/bin/emctl start agent

Use the following commands to turn off all components installed by this article.

#!/bin/bash
export ORACLE_HOME=/u01/app/oracle/product/12.2.0.1/db_1
export OMS_HOME=/u01/app/oracle/middleware
export AGENT_HOME=/u01/app/oracle/agent/agent_inst

# Stop everything
