RAC lab Part 2 – Virtualbox installation and configuration
RAC lab Part 3 – VMs configuration
RAC lab Part 4 – Installing the Openfiler software
RAC lab Part 5 – Installing OEL 7.x on VM
RAC lab Part 6 – OEL 7.x configuration for Oracle 12c GI & RAC DB installation
RAC lab Part 7 – Openfilers configuration and cloning
RAC lab Part 8 – OEL 7.x prepare storage
RAC lab Part 9 – Clone first RAC node as 2nd node and prepare config.
RAC lab Part 10 – Installing Grid Infrastructure
RAC lab Part 11 – Installing Database Software
RAC lab Part 12 – Creating a Container Database
Why Ubuntu you might ask?? Well, by accident :), really!!. I had bought Tplink Wifi USB dongle and it wasn’t supported on OEL 7.2 that I used to install everywhere around. I needed to find something else. Ubuntu seems to be the most popular linux desktop distribution in the world. So why not to try??
My plan is to build Virtualbox environment for my RAC laboratory, let’s see how it goes and if it ends up successfully. I hope!!.
First of all, take a look at what my plan is for the LAB.
As I have mentioned, I want to install Virtualbox software on Ubuntu and create Virtual Guests on it. Two guest are going to be dedicated for OpenFiler software. The OpenFiler is a Open Source Storage Management Appliance. In my case it provides iscsi storage by utilizing local storage, it’s working like a storage proxy. I could use local storage of VirtualBox you might say, you could be absolutely right, but I want my configuration to be more enterprise-like. To add more complexity I am gonna leverage two separate OpenFiler servers to be able to use normal redundancy in ASM diskgroups.
Read more about OpenFiler here: http://www.openfiler.com
Having storage infrastructure, I will be able to build Oracle RAC using shared storage presented by OpenFiler servers. I can create as many future RAC nodes as memory accommodates, but in this simple example just 2 will be brought to life. I am gonna install OEL 7.2 as a base OS platform for Oracle Software installation.
VirtualBox infrastructure will provide 3 networks for the guests.
- Storage network for storage iscsi traffic
- Interconnect network for private RAC communication (cache fusion, cluster synchronization, heartbeat)
- Public network for client and admin access
This post includes installation of Ubuntu as a base for VirtualBox. I will try to present more important steps skipping simple ones like time zone settings in gui in example. I will not show exact steps of partitioning process as the real layout on my server is really really complicated (windows partitions interlaced with the linux ones).
I. Ubuntu 16.04 step by step installation
- Download Ubuntu from its official page at https://www.ubuntu.com/
I am not going to build any kind of server services over my Ubuntu machine, so all I need is a desktop version of 16.04 release.Please find the link pointing directly to the iso file below of Ubuntu 16.04 LTS Desktop 64bit:
https://www.ubuntu.com/download/desktop/thank-you?version=16.04.1&architecture=amd64 - Burn bootable USB or DVD
After the file has been downloaded pull UnetBootin software in order to create bootable USB or CD. Please follow the instructions on the tool’s homepage to burn the ISO grabbed in step 1: https://unetbootin.github.io/
- Boot your computer from USB or DVD and follow the steps
- After booting the server/computer you have many options to choose from like disc check etc. Just run Install Ubuntu
- Choose installation language
- If installer detects Wifi adapter it may ask you to provide network credential
It is not necessary, but allows to download OS/packages updates during the installation process
- Choose to install additional drivers – I guess it is not required, but wanted to be sure all is in place if any custom hardware exists in my box.
- Choose partitioning schema accordingly to your needs. You can erase all the disks and install ubuntu, or keep the content just installing Ubuntu beside of other OSes like Windows. I have very complicated disk layout so there is no sense in going to deeply into the details. Consider having around 200G for your Virtualbox guests, and 50G for operating system.
- Choose polish keyboard if you like all those ąęśżćół :), or choose any other you like
- Provide details of regular user’s account
- Changing hostname and domain name
If you want to change your hostname and change domain name do the actions in the code below.
First take a peek at how it looks now
# To set new server name use hostnamectl tool # It sets hostname dynamically and statically in /etc/hostname maciek@trying ~ $ sudo hostnamectl set-hostname macieksrv # To set domain name # add macieksrv.dba24.pl at the beginning of the second entry in the hosts file maciek@ ~ $ cat /etc/hosts 127.0.0.1 localhost 127.0.1.1 macieksrv.dba24.pl macieksrv
Let’s check the effect
Exactly as expected!!
- Setting bash prompt
I really like to know where I am after logging in, if this is production or not. It can be done by adding the following lines at the end of your users’ .bashrc file (in their home dirs).if hostname -f | grep -qE 'tst|dev|pre|uat'; then _ROOT_COLOR=33 # yellow _USER_COLOR=36 # cyan else _ROOT_COLOR=31 # red _USER_COLOR=32 # green fi if [ "`id -u`" -eq 0 ]; then PS1="\[\033[0;${_ROOT_COLOR}m\]\u@$(hostname -f)\[\033[0;34m\] \w #\[\033[00m\] " else PS1="\[\033[0;${_USER_COLOR}m\]\u@$(hostname -f)\[\033[0;34m\] \w $\[\033[00m\] " fiYou can read more about customizing your prompt here:

- Update Ubuntu after installation
I remember that years ago when I was using debian it was good to update all the packages having new updated versions in the internet repository right after the fresh installation. The update itself was performed by invoking apt-get tool.There are two options available in Ubuntu as described below, I will go with the second one.
upgrade
upgrade is used to install the newest versions of all packages currently installed on the system from the sources enumerated in /etc/apt/sources.list. Packages currently installed with new versions available are retrieved and upgraded; under no circumstances are currently installed packages removed, or packages not already installed retrieved and installed. New versions of currently installed packages that cannot be upgraded without changing the install status of another package will be left at their current version. An update must be performed first so that apt-get knows that new versions of packages are available.dist-upgrade
dist-upgrade in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a “smart” conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary. The dist-upgrade command may therefore remove some packages. The /etc/apt/sources.list file contains a list of locations from which to retrieve desired package files.First we need to update the our local repo cache with information about any new software versions available
maciek@macieksrv.dba24.pl /etc # sudo apt-get update Hit:1 http://pl.archive.ubuntu.com/ubuntu xenial InRelease Get:2 http://pl.archive.ubuntu.com/ubuntu xenial-updates InRelease [95,7 kB] Get:3 http://security.ubuntu.com/ubuntu xenial-security InRelease [94,5 kB] Hit:4 http://pl.archive.ubuntu.com/ubuntu xenial-backports InRelease Fetched 190 kB in 5s (34,5 kB/s) Reading package lists...

“The following packages were automatically installed and are no longer required:” is telling me that those packages that were installed due dependency resolution, are no longer required, as the packages that depend on them has been removed or have other dependencies. We can remove them with simple:

Yup, it looks fine now.
Just create a place to store your Virtualbox resources as the last step, a leave it to you where you keep it. I prefer meaningful mount points like /vbox-repo1. - Disable IPV6
Since I don’t have plans of using IPv6 addressing in my environment and my ISP doesn’t require it I am going to disable it accordingly to the helpful note:
http://www.binarytides.com/disable-ipv6-ubuntu/
Disabling IPv6 looks differently in different Linux distributions.In my case I will create additional file in /etc/sysctl.d/ called 11-ipv6-disable.conf
and put the lines below inside it. Remember to run sysctl -p /etc/sysctl.d/11-ipv6-disable.conf to enable those changes.maciek@macieksrv.dba24.pl /etc/sysctl.d $ sudo cat /etc/sysctl.d/11-ipv6-disable.conf net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 # Check if settings enabled maciek@macieksrv.dba24.pl /etc/sysctl.d $ sudo sysctl -a|grep disable_ipv6|grep -v stable sysctl: reading key "net.ipv6.conf.all.stable_secret" sysctl: reading key "net.ipv6.conf.default.stable_secret" sysctl: reading key "net.ipv6.conf.eno1.stable_secret" sysctl: reading key "net.ipv6.conf.lo.stable_secret" sysctl: reading key "net.ipv6.conf.wlx98ded00b5b05.stable_secret" net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.eno1.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 net.ipv6.conf.wlx98ded00b5b05.disable_ipv6 = 1 #Check if ipv6 settings disappeared maciek@macieksrv.dba24.pl /etc/sysctl.d $ ip a 1: lo: <loopback,up,lower_up> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 2: eno1: <no-carrier,broadcast,multicast,up> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000 link/ether 90:b1:1c:6b:a8:db brd ff:ff:ff:ff:ff:ff 3: wlx98ded00b5b05: <broadcast,multicast,up,lower_up> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 98:de:d0:0b:5b:05 brd ff:ff:ff:ff:ff:ff inet 192.168.1.100/24 brd 192.168.1.255 scope global dynamic wlx98ded00b5b05 valid_lft 66534sec preferred_lft 66534secIPv6 disabled successfully!!

Extras: Quick LVM tutorial
This part is not directly related to what you might need to build your own environment. As I said before, my disk layout is quite complicated, I got few disks with interlaced partitions and while waiting for new empty SDD disk to come I need to laverage what I got at this moment.
I have prepared two empty partitions both around 111GB one on disk no. 2 (the one and only there) and second on disk no 3. I want to build stripe comprising of those two partitions what is to give me around 220GB of disk space for Virtualbox resources.
Ubuntu desktop in my configuration has no LVM installed so I need to start everything from scratch.
