Hello, there! With another Ubuntu release, it has come the time to update our series of posts on how to install Oracle 11g on Ubuntu. If you’ve been following, we’ve been publishing updated howtos since Ubuntu 7.04:
- Installing Oracle 11g on Ubuntu 8.04 Hardy Heron LTS
- Installing Oracle 11g on Ubuntu 7.10 Gutsy Gibbon
- Installing Oracle 11g on Ubuntu 7.04 Feisty Fawn
In fact, in this article I refer several times to previous posts regarding some configuration aspects and why I chose particular values. Also, note that this series of posts is a work in progress and we were able to improve this series with your help. So please do post comment below as your collaboration is very much appreciated.
In this post, we’ll see the steps needed to install Oracle 11gR1 on an Ubuntu 8.10 Intrepid Ibex box all the way to creating your very first database. I’ve been working very hard to ensure that at every new post, the results you get when executing this procedure are as deterministic as possible, leading to a successful setup.
Please keep in mind that this is not a supported architecture, so pay special attention to the order in which I do things. Don’t rush and try to merge steps, as it took me a lot of attempts to make this setup work properly. There are some reboots and also there’s a specific order you need to do things, so please follow the instructions step-by-step and verify the the results of every single command.
Let’s get down to it, shall we? The first thing to do is to get some files. We need an ISO image of Ubuntu (a CD/DVD will do) and one of Oracle 11gR1. Get Ubuntu 8.10 Server here; and Oracle 11gR1 here. (It’s free, but you have to register on the Oracle website to download it.)
It’s a good idea to check the md5sum of each image after downloading from the Internet.
- Here is the md5sum I calculated on the Oracle package:
I’m using VMWare Server for this article, since it’s very handy when you have to repeat the whole procedure several times until you get the proper sequence; also because it is free as in “free beer” (but not as in “free speech”—see http://vmware.com/products/server/). If you prefer, you can use a physical machine, Xen (http://www.xen.org/) or VirtualBox (http://www.virtualbox.org/) but I’m not covering those here.
I’ve installed a plain-vanilla x86 Ubuntu instance with 512 MB of RAM, but instead of creating a disk with the suggested defaults, I’ve created one single virtual disk with 16 GB instead, so I can be sure not to run out of disk space. During the installation, you should choose guided partitioning and no encrypted home directory, unless you know what you’re doing. Also, as we’re going to do everything remotely in this HOWTO, you will want to request the installation of a OpenSSH server in the last steps of the installation.
On the first boot, let’s check if we have everything we need, such as connectivity and
bott@desktop:~$ ssh email@example.com (...) firstname.lastname@example.org's password: Linux ibex 2.6.27-7-server #1 SMP Fri Oct 24 07:37:55 UTC 2008 i686 (...) pythian@ibex:~$ sudo -l [sudo] password for pythian: User pythian may run the following commands on this host: (ALL) ALL pythian@ibex:~$ logout Connection to 192.168.x.y closed.
If you don’t have access to the box, review your installation, network addresses, etc. Let’s continue by updating every single package on the box:
bott@desktop:~/Desktop$ ssh email@example.com firstname.lastname@example.org's password: (...) pythian@ibex:~$ sudo su - root@ibex:~# apt-get update Hit http://security.ubuntu.com intrepid-security Release.gpg Ign http://security.ubuntu.com intrepid-security/main Translation-en_US (...)

Since we had a kernel upgrade, reboot before continuing:

After rebooting to change the kernel, let’s install all the required packages to continue:
bott@desktop:~/Desktop$ ssh email@example.com firstname.lastname@example.org's password: (...) pythian@ibex:~$ sudo su - [sudo] password for pythian: root@ibex:~# apt-get install gcc make binutils gawk x11-utils rpm alien ksh lsb-rpm Reading package lists...

Setting up build-essential (11.4) ... Processing triggers for libc6 ... ldconfig deferred processing now taking place root@ibex:~#
Now we have all the packages we need, so let’s make sure we have all the requirements to run the Oracle Universal Installer as it was not designed to run on Ubuntu, but rather on Redhat-like systems). First, make sure Bash is your default replacement for
root@ibex:~# cd /bin root@ibex:/bin# ls -l /bin/sh lrwxrwxrwx 1 root root 4 2008-11-02 21:33 /bin/sh -> dash root@ibex:/bin# ln -sf /bin/bash /bin/sh root@ibex:/bin# ls -l /bin/sh lrwxrwxrwx 1 root root 4 2008-11-02 22:34 /bin/sh -> bash root@ibex:/bin#
Let’s create some users:
root@ibex:/bin# cd root@ibex:~# pwd /root root@ibex:~# addgroup oinstall Adding group `oinstall' (GID 1001) ... Done. root@ibex:~# addgroup dba Adding group `dba' (GID 1002) ...

Copy the unpacked Oracle 11gR1 to the box we’re working on:
bott@desktop:~/Desktop$ scp -r database email@example.com: firstname.lastname@example.org's password: (...)
And put our installation files in place:
pythian@ibex:~$ sudo su - root@ibex:~# mv /home/pythian/database /media/database root@ibex:~# chown -R oracle:oinstall /media/database root@ibex:~#
Let’s change some system-wide configuration files, starting with
root@ibex:~# cd /etc root@ibex:/etc# cp sysctl.conf sysctl.conf.original
Edit it, adding the following lines to the bottom of the file:
fs.file-max = 65535 kernel.shmall = 2097152 kernel.shmmax = 2147483648 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 1024 65535 net.core.rmem_default = 4194304 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 262144
Then, let’s modify
root@ibex:/etc# cd /etc/security/ root@ibex:/etc/security# cp limits.conf limits.conf.original
Add the following lines to the bottom of the file:
oracle soft nproc 2047 oracle hard nproc 16383 oracle soft nofile 1023 oracle hard nofile 65535
The last one, for now, is
root@ibex:/etc/security# cd /etc/pam.d root@ibex:/etc/pam.d# cp login login.original
login, adding to it:
session required /lib/security/pam_limits.so session required pam_limits.so
I’m not completely convinced that a reboot is needed here (you probably could get away with
sysctl -p as
root and logging in again as your user) but I do recommend it, just to make sure we are on the same page. Doing so guarantees that we’ve cleaned up our memory and loaded at boot time all the changes we just did.
Once our VM is back online. it’s time to become user
oracle and to fire up the Oracle Universal Installer. Don’t forget to allow incoming connections on your X server with
xhost +192.168.x.y. The IP address
192.168.w.z is the IP address of your X server.

At the end of the installation, the Oracle Universal Installer is kind enough to ask us for confirmation before leaving (you can click on “Installed Products” and review what was installed before leaving the installer:
Now, take note of two things, our
ORACLE_BASE and our
ORACLE_HOME as we’ll use them later:
We now have only the database software, but no database created yet. Let’s get moving and install the few extra packages needed to complete our installation. Please note that on several attempts, I’ve installed all the packages in the earlier step, but all those attempts failed; that’s why we’re installing it just before we actually need it (
dbca will fail without those and the database won’t be created):

Note: Do NOT reboot now.
Creating a database
Let’s install our first database with DBCA (DataBase Configuration Assistant).
root@ibex:~# su - oracle oracle@ibex:~$ export DISPLAY=192.168.w.z:0.0 oracle@ibex:~$ export ORACLE_HOME=/u01/app/oracle/product/11.1.0/oraibex oracle@ibex:~$ export PATH=$PATH:/u01/app/oracle/product/11.1.0/oraibex/bin oracle@ibex:~$ dbca (...some time will pass before you see anything -- be patient...)

Now, wait for a few moments, as
dbca can take up to a couple of minutes to show this initial screen:
That’s right, we want to create a database:
A general Purpose or TransactionProcessing database, next:
And our SID will be
But we don’t want to configure Enterprise Manager just now:
We want to use the same password for both
Nothing fancy, just plain filesystem for storage:
Let’s use the suggested template:
But no recovery area or archiving:
We don’t want the sample schemas or to execute any custom scripts at this time:
You can tune this if you want, but I’d suggest leaving it as-is unless you know what you’re doing:
As well as sticking with the suggestion of keeping the enhanced default security settings:
I don’t want any automatic unattended tasks running:
Check your filesystem layout, then hit
Yes, we want it to go ahead and create the database. Hit
Finish this time.
It will show what it’s about to do. Check it out, then hit
OK when ready.
And it will get to work, creating your first database:
Go get another cup of tea:
And keep watching the screen until you see something like this:
At this point, you’ll have an empty database created.
Time to check it out. First test: we shut it down and restart it.
