.
\nToday every DBA should have a lab on his laptop. This is where I reproduce most of cases before opening a SR, or to investigate something, to demo, to learn new features, or to prepare an OCM exam. I’ve a few basic VirtualBox VM with single instance databases (11g and 12c, SE and EE, CDB and non-CDB, etc). I’ve the RacAttack environment with a 3 nodes RAC in 12c on OEL7. But in order to prepare for OCM12c upgrade, I need also a Cloud Control 12c. Here is how I got it without having to install it.
\n
\nOracle provides some VirtualBox images, and there is one with Oracle Enterprise Manager Cloud Control 12c Release 5 (12.1.0.5) and a database (11.2.0.4) for the repository.

\n

Download

\n

You can get the image from: https://edelivery.oracle.com

\n

Filter products by ‘Linux/OVM/VMs’ and search for ‘Enterprise Manager’:

\n

\"CaptureVBCC001\"

\n

It’s 17GB in total to download, so be patient:

\n

\"CaptureVBCC002\"

\n

You can also download a wget script to get all files:

\n

\"CaptureVBCC003\"

\n

So you have 6 files and you can unzip them. When you see the compression ratio you can ask why it is zipped…

\n

Then concatenate all .ova files:

\n
\nC:\\Users\\frp>cd /d F:\\Downloads\nF:\\Downloads>type VBox*.ova > EM12cR5.ova\n
\n

and you can import it with VirtualBox as any OVA.

\n

Network

\n

I have all my VMs on the host-only network (192.168.78.1 in my case).
\nOn the VM configuration, I set the first network card on ‘host only’ network and the second one as NAT to be able to access internet.
\nIf you imported the OVA without changing the MAC addresses, here they are: 0800274DA371 and 08002748F74B

\n

Now I can start the VM and login as root – password welcome1

\n

My keyboard is Swiss French layout, so I change it in System/Administration/keyboard

\n

Then I want to be able to ssh to the machine so I set the network (System/Administration/Network)

\n

Here is my configuration in my case;
\n\"CaptureVBCC011\"

\n

Then I activate the interface and can connect with ssh:
\n$ ssh root@192.168.78.42

\n

Stop iptables as root

\n

I want to communicate with the other VMs to discover databases, and to access via web, so I disable the firewall:

\n
\n[root@emcc ~]# /etc/init.d/iptables stop\nFlushing firewall rules:                                   [  OK  ]\nSetting chains to policy ACCEPT: filter                    [  OK  ]\nUnloading iptables modules:                                [  OK  ]\n[root@emcc ~]# chkconfig iptables off\n
\n

then I can connect as oracle

\n
\n$ su - oracle@192.168.78.42\n \nInstallation details of EM Plugin Update 1 12.1.0.5.0 .....\n \nEM url: https://emcc.example.com:7799/em\nPorts used by this deployment at /u01/OracleHomes/Middleware/oms/install/portlist.ini\nDatabase 11.2.0.4.0 location: /u01/OracleHomes/db\nDatabase name:                emrepus\nEM Middleware Home location:  /u01/OracleHomes/Middleware\nEM Agent Home location:       /u01/OracleHomes/agent/core/12.1.0.5.0\n \nThis information is also available in the file /home/oracle/README.FIRST\n \n \nTo start all processes, click on the start_all.sh icon on your desktop or run the script /home/oracle/Desktop/start_all.sh\n \nTo stop all processes, click on the stop_all.sh icon on your desktop or run the script /home/oracle/Desktop/stop_all.sh\n
\n

You just have to follow what is displayed

\n

start_all.sh

\n

Here is how to start everything in the right order.

And it’s ready. You can access to it from the VM console, or the host browser on https://192.168.78.42:7799/em

\n

All passwords are welcome1.

\n

You can discover the others hosts. I’ve put them n the /etc/hosts in the EM VM, and I’ve put the following line in all /etc/hosts where I want to install agents:

\n
\n192.168.78.42 emcc emcc.example.com\n
\n

Hope it helps. There are things that are quicker to do from Cloud Control when you are in OCM exam so better to know it. However, don’t rely on that only as it may not be available for all exercises.
