Installing Oracle 11g on Ubuntu Linux 7.04

Posted in: Technical Track

Note: Installing Oracle 11gR1 on Ubuntu 8.10 Intrepid Ibex is now published.

Note: I have now published “Installing Oracle 11g on Ubuntu Linux 7.10 (Gutsy Gibbon)”

Note: This page focuses on Ubuntu installs. Oracle has published a web page for successfully installing Linux on unsupported platforms that you may find helpful.

I come from a MySQL background, and I have been given the challenge of learning Oracle. I can’t just play around with our customers’ databases, but I remembered that Paul Vallée said that there is nothing wrong with learning on company time. So I decided to install my own Oracle database, which I’ll be free to destroy in every way I can think of… and of course, free to bring it back to life. Recovering from crashes will probably be the most difficult part of my adventures in the Oracle world, but let’s take one step at a time, shall we?

Now, onto Oracle 11g (beta 5) on Ubuntu 7.04 (Feisty Fawn). One little issue is that Ubuntu is unsupported by Oracle. So, through this text, we will trick the Oracle installer into thinking it’s actually running on a Red Hat box.

Step Zero

This tutorial was based on a document which can be found here. I have adapted it for Oracle 11g.

Get a copy of Ubuntu 7.04 and install on a machine. I’m using the 32-bit version here (as well as for Oracle). Next, make sure your system is up-to-date. A simple apt-get update followed by a apt-get upgrade will do the trick, although you may prefer using the GUI Synaptic Package Manager — it’s entirely up to you what method you choose. However, I much prefer to use the command line.

As you go through updates, sometimes a reboot will be needed (usually to boot from a newer, recently-updated kernel). Sometimes it’ll just ask you to restart your web browser or some other program as a new version is installed.

It’s important to have a few gigabytes of free disk space and a total of 1 GB of memory before starting this. This 1 GB of memory can be RAM alone or the combination of RAM and swap space. Of course, since everything runs faster when in RAM, the more of it, the better.

Very important: get Java running before trying to move on. My guess is that almost any JRE (java runtime) or JDK (java development kit) will work. I’m not sure which is the minimum version required: I used Sun JDK 1.5.

Step One

Install some system requirements. There are a few packages that I had to install on this box (it was a recently installed system which didn’t have all these packages). After several attempts of installing Oracle, the equivalent command-line for installing all the necessary packages at once was something like this:

# apt-get install gcc make binutils lesstif2 libc6 libc6-dev rpm libmotif3 libaio libstdc++5 gawk alien libg++ ksh gcc-3.3 g++-3.3 libstdc++5

It’s possible that when installing the packages mentioned above, the installer will install some other prerequisites as well, as these packages themselves may have prerequisites.

Step Two

Choose where you are going to install your Oracle 11g server and create the ORACLE_BASE directory. This is the place where Oracle will be installed. Make sure there is at least 3 GB on the partition/mount point before moving to the next step. After installed, my basic installation took about 3.4 GB on disk (without the starter database!). As your database grows, it will need more space. Reserve a total of at least 6 GB for the unpacked installer and the basic installation. You can get rid of the installer files afterwards.

# mkdir -p /u01/app/oracle

Step Three

Add a few users and change groups to make the installer more comfortable. Remember, we are tricking the installer to think it’s installing on a Red Hat box.

# addgroup oinstall
# addgroup dba
# addgroup nobody
# useradd -g oinstall -G dba -p password -d /home/oracle -s /bin/bash oracle
# usermod -g nobody nobody

The usermod command is needed since because when running, the installer looks for a user called nobody which is part of a group named nobody (in Ubuntu, the user nobody it’s assigned to nogroup by default).

Step Four

Make some symlinks. Apparently, the installer uses absolute paths, so it must find the binaries in the right places.

# ln -s /usr/bin/awk /bin/awk
# ln -s /usr/bin/rpm /bin/rpm
# ln -s /usr/bin/basename /bin/basename

Step Five

We need to mimic the /etc/rc.d directory structure of a Red Hat box. We do this with more symlinks:

# mkdir /etc/rc.d
# ln -s /etc/rc0.d /etc/rc.d/rc0.d
# ln -s /etc/rc2.d /etc/rc.d/rc2.d
# ln -s /etc/rc3.d /etc/rc.d/rc3.d
# ln -s /etc/rc4.d /etc/rc.d/rc4.d
# ln -s /etc/rc5.d /etc/rc.d/rc5.d
# ln -s /etc/rc6.d /etc/rc.d/rc6.d
# ln -s /etc/init.d /etc/rc.d/init.d

Step Six

I’ve created a file called /etc/redhat-release and put only one line on it. The same can be achieved by issuing the following as root:

echo "Red Hat Linux release 4" > /etc/redhat-release

Step Seven

We tweak the system default limits on a few items. The shared-memory are specially important, since Oracle relies on shared memory for process communications. There is a file called /etc/sysctl.conf and it should have these lines on it:

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 65000
net.core.rmem_default = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144

Now that they are in a config file, these limits will be issued automatically at the next boot sequence. For now, we need to make the system re-read the config file:

# sysctl -p

Now, what do those parameters and values actually mean?

  • fs.file-max sets the maximum number of open files that can be handled by the Linux kernel.
  • kernel.shmall determines the total amount of shared memory to be allocated in pages. In this example, I’ve set it to 8GB, which is way above the amount of memory I can handle in my box, even with swap.
  • kernel.shmmax controls the maximum amount of memory to be allocated for shared memory which in this example is 2GB.
  • kernel.shmmni defines the maximum number of segments system-wide.
  • net.core.rmem_default and net.core.rmem_max define the default and maximum read buffer queue for network operations (1 MB in this example)
  • net.core.wmem_default and net.core.wmem_max define the default and maximum write buffer queue for network operations (256 KB in this example)
  • net.ipv4.ip_local_port_range tells the kernel the port ranges that will be used for outbound connections.
  • kernel.sem has four parameters:
    1. SEMMSL – semaphores per array
    2. SEMMNS – max semaphores system-wide (SEMMNI*SEMMSL)
    3. SEMOPM – max operations per semop call
    4. SEMMNI – max number of semaphore arrays

To check your current semaphores configuration, you can run cat /proc/sys/kernel/sem or ipcs -ls. On my machine, after the modifications on sysctl.conf, these commands output:

# cat /proc/sys/kernel/sem
250     32000   100     128

# ipcs -ls

------ Semaphore Limits --------
max number of arrays = 128
max semaphores per array = 250
max semaphores system wide = 32000
max ops per semop call = 100
semaphore max value = 32767

(I really don’t know if these are enough or too much, but I’ll keep you posted.)

For a better understanding of these kernel-tweaking settings, I’d recommend these resources:

Step Eight

Add these lines to /etc/security/limits.conf, letting the oracle user use more resources than the defaults allowed. You may notice that all these values are a power of 2 minus one. When soft limits are exceeded, you’ll get a warning; the hard limits can’t be exceeded in any situation: you’ll get an error. I’m not completely sure, but I think these limits apply to each session/login (and since Oracle doesn’t exactly log in to the machine, my best guess is these limits apply per instance running).

oracle soft nproc 2047
oracle hard nproc 16383
oracle soft nofile 1023
oracle hard nofile 65535

Step Nine

Make sure the limits.conf is being interpreted as the oracle user logs in by adding these lines to /etc/pam.d/login. You will want to make sure that is actually happening, since the defaults are way lower and you may get all sorts of problems.

session required /lib/security/
session required

Step Ten

Unpack and prepare the installation.

# cd /path/to/zipfile
# unzip

(And wait… wait a bit more… go get a cup of coffee…)

After your second cup of coffee, you should have a multi-gigabyte set of files; this is our installer.

# chown -R oracle:oinstall database
# chown -R oracle:oinstall /u01/app/oracle

Step Eleven

Fire up the installer as the oracle user itself. This is what you will probably see on the output window:

# su - oracle
$ cd /path/to/extracted/zip/file
$ ./runInstaller

rpm: To install rpm packages on Debian systems, use alien. See README.Debian.
error: cannot open Packages index using db3 - No such file or directory (2)
error: cannot open Packages database in /var/lib/rpm

There are a few errors that can be safely ignored: the ulimit and the RPM-related errors, since the limits don’t restrict the installer and since we actually don’t have a RPM database on the machine — we are running on Ubuntu, remember?

After a few moments, you will be prompted to choose where to install the Oracle server. You’ll notice that I asked the installer to not create a starter database — I did that later. Choose the Oracle Base and correct the group if needed. I personally recommend sticking with the defaults if you are a newbie like me.


As you press the Next button, you will be prompted where to install the Inventory — leave it that way unless you know what you are doing (if this were the case, you wouldn’t be reading this text anyways). Also correct the OS group name if needed and hit Next.


Since I’ve chosen to install the server in the same directory as the oracle user’s HOME directory, the installer will issue a warning. I simply ignored it and continued with the installation.


After that warning, I tried to perform some prerequisite tests, and yes — some will fail. Just mark the failed boxes and hit Next (after trying a few times to fix those issues, I’ve decided to call the installer’s bluff and… it worked!)


After all this warning stuff, it’ll ask you to check the list of products to be installed. I was amazed when I read that 122 different products would be installed on my box. Hit Next.

Go get some coffee.


And some more coffee.


And even more coffee.


You may like to go to the washroom after so much time drinking coffee. Remember: I was installing on a 3 GHz machine with 1 GiB of RAM with SATA2 disks — this box is supposed be blazing fast.


At some point, it will ask you to run some commands as root. Do that when it asks, since the install depends on a few modifications on the base system (like creating the /etc/oratab file).

$ sudo -s

# /u01/app/oracle/oraInventory/
Changing permissions of /u01/app/oracle/oraInventory to 770.
Changing groupname of /u01/app/oracle/oraInventory to oinstall.

Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created

Finished product-specific root actions.

After these scripts finish their execution (the errors seem to be ignorable), hit the OK button and you’ll have a window that (probably) will look like this one:


Just hit OK to get out the installer. The basic installation is… not over yet.


To allow Oracle start on boot-up, create a file called oracledb (or whatever name you want to call it) and put it in /etc/init.d with the contents below. This script was copied and pasted from a tutorial by Graham Williams. It will read the /etc/oratab and fire up any instances it finds.

# /etc/init.d/oracledb
# Run-level Startup script for the Oracle Instance, Listener, and Web Interface

export ORACLE_HOME=/u01/app/oracle


# if the executables do not exist -- display error

if [ ! -f $ORACLE_HOME/bin/dbstart -o ! -d $ORACLE_HOME ]
    echo "Oracle startup: cannot start"
    exit 1

# depending on parameter -- startup, shutdown, restart
# of the instance and listener or usage display

case "$1" in
        # Oracle listener and instance startup
        echo -n "Starting Oracle: "
        su $ORA_OWNR -c "$ORACLE_HOME/bin/lsnrctl start"
        su $ORA_OWNR -c $ORACLE_HOME/bin/dbstart
        touch /var/lock/oracle

        su $ORA_OWNR -c "$ORACLE_HOME/bin/emctl start dbconsole"
        echo "OK"
        # Oracle listener and instance shutdown
        echo -n "Shutdown Oracle: "
        su $ORA_OWNR -c "$ORACLE_HOME/bin/lsnrctl stop"
        su $ORA_OWNR -c $ORACLE_HOME/bin/dbshut
        rm -f /var/lock/oracle

        su $ORA_OWNR -c "$ORACLE_HOME/bin/emctl stop dbconsole"
        echo "OK"
        $0 stop
        $0 start
        echo "Usage: `basename $0` start|stop|restart|reload"
        exit 1

exit 0

After saving the file, make it executable

# chmod a+x /etc/init.d/oracledb

and if you want, make it run at every boot:

# update-rc.d oracledb defaults 99
Adding system startup for /etc/init.d/oracledb ...
/etc/rc0.d/K99oracledb -> ../init.d/oracledb
/etc/rc1.d/K99oracledb -> ../init.d/oracledb
/etc/rc6.d/K99oracledb -> ../init.d/oracledb
/etc/rc2.d/S99oracledb -> ../init.d/oracledb
/etc/rc3.d/S99oracledb -> ../init.d/oracledb
/etc/rc4.d/S99oracledb -> ../init.d/oracledb
/etc/rc5.d/S99oracledb -> ../init.d/oracledb

Before finishing, add the following lines to your /etc/profile . Be careful, since these values are valid system-wide. So make sure the paths are set according to your particular setup (if you have been doing everything according to this text, you should be fine).

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.1.0/db_1
export PATH=$PATH:/u01/app/oracle/product/11.1.0/db_1/bin

Last operation: add yourself to the dba group. You can use usermod or just edit the /etc/groups file and add your username at the end of the line that starts with dba (my username is ‘bott’):


If you chose to not create a starter database during your install, you’ll have to do two extra steps. You should create a listener (with netca) and after that, create the starter database (also with netca). If you chose to have the installer create a database for you, then you should be fine, since when doing that, it asks for a password for the default accounts (SYS, SYSTEM, and DBSNMP, SYSMAN if you choose to install it with the enterprise manager option selected).

If everything has gone well, open a terminal window and, as the oracle user, type:

Great job Augusto. I am now very tempted to destroy my Enterprise Linux 5 setup again and go afterall with Ubuntu. One of the reasons is that Ubuntu probably gives me a better desktop experience (and hopefully WPA wireless access) and better community support. As said. Thank you very much for sharing !

Great tutorial Augusto,

Especially nice was the script you included to autostart the DB and listeners. That is what usually trips folks up when installing Oracle DB.


Great instructions! I was successful after getting all of the packages installed correctly.
I would recommend running apt-get one at a time to make sure.
lesstif2 wouldn’t update or is no longer available but that didn’t seem to matter.
Just wanted to get my hands on the newly released copy of 11g and I had an Ubuntu desktop handy.

Very good text…
Than’s my friend
I install here oracle 11g for ubuntu 7.04

Marcio Novelli

Marília – S.P



I believe that on step seven these

net.core.rmem_default = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144

are not correct values. according to the Oracle11g documentation they should be more like

See; 2.7 Configuring Kernel Parameters

rmem_default 4194304
rmem_max 4194304
wmem_default 262144
wmem_max 262144



You are probably right – thanks for the input. This text was written before the ‘official’ documents were released and were based on other howtos and your input made me wonder: why Oracle would raise their recommended default OS receive buffer size from 1M to 4M?
Anyway… thanks again.

As per your instructions I tried to intall ORACLE 11g on my UBUNTU system which is Ubuntu 6.06 LTS Desktop Edition.

I reached till step 11. But after running the script runInstaller of ORACLE 11g the intallation gets stuck at 17%. I’m getting the same errors as you repoerted like to install rpm package use alien, cannot open package database in /var/lib/rpm etc.

Could you please help me out.

One more thing whenever I work in oracle user mode I’ve to set DISPLAY variable.



I haven’t really tried it with 6.06 LTS, so your input is welcome. Is there any disk activity when it seems stuck on the 17%? Did you check if you’re hitting swap on your machine (so the installation seems stuck but instead is trying to free up some RAM to move on?). The DISPLAY variable should be carried on if you ‘sudo -s’ (from your ‘regular user’). The dash sign on the ‘su -‘ command means it’ll force the command interpreter to re-read the environment variables (I had to set DISPLAY anyway since I was installing on a remote machine). See the following example on the behaviour of the ‘-‘ parameter for ‘su’:

[email protected]:~$ echo $DISPLAY
[email protected]:~$ sudo -s
[email protected]:/home/bott$ echo $DISPLAY
[email protected]:~# su – oracle
[email protected]:~$ echo $DISPLAY

[email protected]:~$ exit
[email protected]:~# su oracle
[email protected]:/home/bott$ echo $DISPLAY


I don’t know what is happening. Coz when I tried to install 11g without the starter database the setup was stuck at 21%.
The display variable is quite correct as per your instruction. There is no other disk activity apart from OUI.

Regarding SWAP how can I check it. When I tried to install it second time I left OUI to do its work whole night ( 7hours ).

My system conf is: Intel 865GBF motherboard, two 80-80 GB ATA harddisks, 512+256 RAM DDR1, P-4 with HT 2.9GHz


I forgot to mention about swap space. It is 1GB.



I don’t think I’m following what you mean – so I believe it’s best to give you some pointers/clues to check what can be happening. The installation gets stuck at 17% or at 22%? How can you tell the difference on disk activity between the Oracle installer or anything else? Have you checked ‘top’, ‘iostat’ or ‘sar’ (on package ‘sysstat’)? The machine I was working on had 1 GiB of RAM and if touched the swap space, was just a little bit… My best idea so far would be investigating a bit further with the tools I’ve mentioned.

Anyways – good luck!


Couple of days back I installed my first Linux (Ubuntu 7.04). Today i began Oracle 11g installation using procedure documented by you. Thank you.

I encountered a couple of problems while implementing Step 7.

command “sysctl.conf -p” didn’t work until i specified the full path of the file. Current active directory is ‘/etc’. Not specifying the complete path causes the following error to be generated “bash: sysctl.conf: command not found”.

Secondly, attempt to re-read the file failed producing the following errors.

/etc/sysctl.conf: line 28: fs.file-max: command not found
/etc/sysctl.conf: line 29: kernel.shmall: command not found
/etc/sysctl.conf: line 30: kernel.shmmax: command not found
/etc/sysctl.conf: line 31: kernel.shmmni: command not found
/etc/sysctl.conf: line 32: kernel.sem: command not found
/etc/sysctl.conf: line 33: net.ipv4.ip_local_port_range: command not found
/etc/sysctl.conf: line 34: net.core.rmem_default: command not found
/etc/sysctl.conf: line 35: net.core.rmem_max: command not found
/etc/sysctl.conf: line 36: net.core.wmem_default: command not found
/etc/sysctl.conf: line 37: net.core.wmem_max: command not found

When i look under \proc\sys\ directory i see the files mentioned in the above commands. I’m not sure if the two are related.

What should i do to get past this problem? If you deal strictly with Oracle and not configuration, can you please direct me to a website where i can find help.

Ami i missing an entry in the “system path” environment variable or something?

Thanks Again.



use “sysctl -p” instead (not “sysctl.conf”)


Thank Alex. That worked. I didn’t realize suppressing file extension is mandatory.



When i try to run installer (step 11), i get the following message ….

Can you please help me out?

“Suppressing” file extension is mandatory to call the right thing, yes :)

Appreciate your immediate response.




Checked on my box (which runs Feisty):

[email protected]:~$ dpkg –list | grep -i libc6
ii libc6 2.5-0ubuntu14 GNU C Library: Shared libraries
ii libc6-dev 2.5-0ubuntu14 GNU C Library: Development Libraries and Hea
ii libc6-i686 2.5-0ubuntu14 GNU C Library: Shared libraries [i686 optimized]

I’m sure you probably already have it – just make sure you have the ‘dev’ lib also (if I’m not mistaken Oracle needs to build and link some runtime libs).



Hi. I’m trying to install Oracle 10g on ubuntu Feisty Fawn. When I try to run runInstaller. I get the following error

.oui not found

any ideas why?



It seems the installer is complaining about not finding oui (Oracle Universal Installer). That’s odd – as far as I know, the Oracle Installer ships its own Java Virtual Machine on the installation package. I’ve done some browsing around and found references to possible incorrect session variables, possible left overs from another misconfigured JVM. Try listing the session variables on your system with env and perhaps getting rid of any suspicious variables/values with unset.



Hi, I also got the .out not found — then I realized that I had inadvertently d/l the x86 version and I’m on an x64 arch.

$ file /install/.out

indicated this is an ELF 32-bit LSB executable…when you try to run this on x64, it just says “file not found”.

I just checked Oracle’s site, and there is no download for x64 11g (yet), so I’m stuck with 10gR2 for now.



I really haven’ tried that, but you may want to try installing 32 bit libraries with sudo apt-get install linux32 ia32*. As far as I know, that’s the way to go with many 32 bit applications in a 64 bit Ubuntu. Let us know the outcome and good luck!


The install goes fine until the Linking phase when it tells me that all this stuff can’t be found or linked.

During the Pre-requisite check, it is telling me I don’t have glibc installed as well.

Error message:

Checking Recommended glibc version
Expected result: ATLEAST=2.3.4-2.19
Actual Result: package glibc is not installed

seems I should have it just fine

[email protected]:/home/oracle# dpkg –list | grep -i libc6
ii libc6 2.5-0ubuntu14 GNU C Library: Shared libraries
ii libc6-dev 2.5-0ubuntu14 GNU C Library: Development Libraries and Header Files
ii libc6-i386 2.5-0ubuntu14 GNU C Library: 32bit shared libraries for AMD64

I couldn’t find that package you listed:

[email protected]:/home/oracle# apt-get install libg++
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Couldn’t find package libg++



You shall be safe ignoring the prerequisite check on glibc (since you already checked and have a suitable version). Just mark the checkbox on that step of the installation (that’s what I did). Regarding libg++, make sure you have the ‘universe’ repository enabled (after uncommenting the repository, make sure you run sudo apt-get update).

Good luck!

Mr. Bott,

great work! Especially the depencies, you must have spent some time figuring that out I guess.
I just followed your guidelines to install it on a laptop with only 750 MB of ram, running an ubuntu 7.10 and apart from some minor details (which I hardly dare to mention below) it worked great.


Step 11:
– /etc/group (not : /etc/groups)
-When not choosen to create a db during install, it must be dbca (not netca, which is for the listener setup) to create a new instance

My experience:

listener did not start after setup with netca, it complained that the port was already in use, which wasn’t the case.
Manually edited the $ORACLE_HOME/network/admin/listener.ora which had the hostname missing (wild guess is that netca might have had a problem with figuring out the hostname or ip, not sure), any how with a listener.ora like this, it works (of course the db is only accesable from localhost, which for a production db would not make much sense):

(ADDRESS = (PROTOCOL = TCP)(HOST=localhost)(PORT = 1521))



That’s curious. You seem to have the proper sources configured. Anyway, I’m working on a new version of this howto for Gutsy (7.10). It should be published soon.



Thanks for your feedback! Comments like yours give us the strength to move on, trying to improve our own work. As mentioned on the other comment, I’m working on a new version of this document and your input is more than welcome. Thanks again!


I failed to mention that I am running the 64 bit version of Ubuntu. Huge mistake and I’ve had nothing but problems with it.


sudo apt-get install libaio1


Fabulous doc! I got it running on Ubuntu 7.10 Desktop without any problems (save for a minor glitch – apt-get install libaio1 (not libaio), as others mentioned.
Also, my init script demands that I run dbstart and dbshut with $ORACLE_HOME as parameter (maybe because I created the database during installation?):

– su $ORA_OWNR -c $ORACLE_HOME/bin/dbstart
+ su $ORA_OWNR -c “$ORACLE_HOME/bin/dbstart $ORACLE_HOME”

– su $ORA_OWNR -c $ORACLE_HOME/bin/dbshut
+ su $ORA_OWNR -c “$ORACLE_HOME/bin/dbshut $ORACLE_HOME”

Many thanks,


What’s scary is that that seems easier than trying to install Oracle 11g on Oracle’s own distro of Linux! Especially considering that the Oracle distro is missing a required RPM in order to use ASM.

If only in my case the database and distro were made by the same company… Oh hang on… they are!



I’ve followed all the instructions you kindly put in this tutorial but there are still problems after the installation has “successfully” finished. I’m installing on a 6.06 LTS ubuntu linux system. After a system reboot oracle was unable to open the database created during installation.
The first error I’gve found is this: I was not able to found the initORCL.ora file in the $ORACLE_HOME/dbs/ folder . After some googling I’ve found a post in a mailing list suggesting to solve the problem simply doing a
cp init.ora initORCL.ora
after this I’m able to connect to sqlplus but ti cannot mount the database:

SQL> alter database mount;
alter database mount
ERROR at line 1:
ORA-00205: error in identifying control file, check alert log for more info

I’ve tried to found the alert.log file but without luck …. I’ve also found a similar problem (also after some googling) in a mailing list but it seems to be originated by an spfile modification (which is not the case because all the files are expected to be created by the installer ……). Any help would be greatly appreciated … Im new to Oracle and I’m a little bit confused.




I have the same problem. I was able to connect to the web interface https://localhost:1158/em… (for exact url, see the output of the oracle startup script; it appears to generate port numbers randomly)
and from there I manually started the instance. Also, make sure your /bin/sh is linked to /bin/bash (not something else like /bin/dash, which doesn’t properly intepret some of the oracle scripts).



… quick update to my post above. Take a look at /etc/oratab which lists the available services. By default, my install didn’t set databases to auto-start which prompted manual intervention after each reboot. In short, the last letter should be Y for autostart:

That took care of it. Take a look at for more info.


fckn DISPLAY … just typed “xhost +” in terminal, and it worked…


Hola para los que tienen el problema:

Comprobando el monitor: debe estar configurado para mostrar al menos 256 colores
>>> No se ha podido ejecutar la comprobación automática de colores de visualización con el comando /usr/X11R6/bin/xdpyinfo. Compruebe si está definida la variable DISPLAY. Fallo <<<<

Fallo de algunas comprobaciones de requisitos. Debe cumplir estos requisitos antes de

continuar con la instalación,en cuyo momento se volverán a comprobar.

¿Desea continuar? (y/n) [n] n

lo pueden solucionar asi:
desde root colocan
xhost +local:oracle

y ya puede continuar con la instalacion

Great page, Augusto. It was extremely useful. My firsrt Oracle install on an unsupported Linux platform (our loved ubuntu) and it was “cut&paste”.
I mention 1 tip. Almost at the end, the Enterprise Configuration Assicant (emca.script) complaint on not getting what he exptets on /etc/oraIst.loc. This would have made emca happy before calling oraInst:
touch /etc/oraInst.loc
chown oracle /etc/oraInst.loc
chgrp dba /etc/oraInst.loc

Great page.
I’ve prepared my spirit for a 2 day fight and my db is up and running on 2 hours.
Thanks again,



I installed oracle 11g and creeate a sample database. every work perfectely. But I cannot connect with the SYS user. In can not stop or start my database. There are some thing wrong on $HOME_ORACLE/lib like lib*


Thanks for this great tutorial. I had tried installing 11g on Fedora 9 64 bit, and I agree with others, 64 bit 11g for Linux is a nightmare. I would suggest making sure that you have all the required 32 bit and 64 bit libraries installed. In many cases I linked the 32 bit path to the 64 bit one, and it seemed to work.

Thanks for the great tutorial. I ran into many troubles with 8.04. If you get around to it, I’d love to see a good comprehensive tutorial on that.

BTW, for the user who asked earlier, my WPA on my iMac works flawlessly!

Thanks again for a great tutorial.

Radio Free Tooting: Installing Oracle 10g on Ubuntu Hardy Heron
June 29, 2008 9:51 am

[…] instead of 11.1.0.To apply the patch you just need to repeat the process.Further ReferencesAugusto’s earlier article on installing on Ubuntu Feisty Fawn (which has some additional explanation of the parameter tweaking) Oracle Release for 10gR2 on Linux […]


FWIW I followed this installation guide on a fresh [and apt-get update’d] install of Hardy Heron.

Here’s the issues I had as I went along:

The initial apt-get command: libaio has been renamed to libaio1.

The DISPLAY environment variable. had to switch to my normal user and type “xhost +” (after install is over type “xhost +localhost”), then back as the oracle user: “export DISPLAY=:0.0”

I also had an error appear:

“Error in invoking target ntcontab.o of makefile[…]”

For which I found this website:

that suggested the following fix:

apt-get install gcc make manpages-dev autoconf automake libtool flex bison gdb binutils

Which did in fact solve the problem.

I then recieved an error on the “Configuration Assistants” dialog: “OUI-25031:Some of the configuration assistants failed/cancelled.” Where, in the Details panel I traced it to “UnsatisfiedLinkError exception loading native library: njni11”

sudo apt-get install libaio1

solved the problem.


“If you see these messages (and I sincerely hope you do) you’re all set!”

Not strictly true…if you created a sample database from the installer.

First, be aware that if you follow the steps exactly as laid out, you will have put this in your /etc/profile:


Notice the installed gave your instance sid “orcl”. This will cause a huge problem, in that you can’t connect to the instance. Change it either when installing or in your profile. And check oratab in /etc/init.d/ to make sure the SID is correct.

If you get a shared pool memory error, open the initSID.ora file and adjust the pool until oracle is satisfied.

It’s also worth mentioning…try to start sqlplus as sysdba to make sure everything is cool:

sqlplus / as sysdba;

(As sysdba you can also check out the instances running in the view v$instance view.)

I also ran across a problem where oracle complained about the control files…

so issuing show parameter control_files from sqlplus as sysdba will give you what the initSID.ora file is looking for. I found out the files simply didn’t exist. So making sure to be user oracle, I just touched the two files:

# touch control_file1
# touch control_file2

then, shutdown the instance:


then, restarted the instance:


And finally, after 4 hours of installing, messing with DISPLAY, permissions, exceptions, etc, the oracle process was running, the instance was started and the database was mounted!


what is the password oracle , i can’t connect i have the message “password for oracle” but i dont have it .

You probably want to install package libaio1 – without that one, dbca won’t run. On step 7 you need to add the lines mentioned to each file (as those lines are usually not present on a standard Linux distribution). May I suggest you take a look at newer versions of this tutorial? Just check out

Hi all,
A great introduction – when do you get the time to write things up :)
I am a firebirder about to play with oracle. Can I install oracle on my home server – ubuntu 8.04 – and get to it from win boxes elsewhere on the network?
There is no gui on the server – it just serves very well

Thank you, thank you.
This page helped me alot, since Im in the middle of installing oracle at school.

Although Im running 10g and Karmic.

Your other tuts are not as wellwritten as this one, imho. Thats why i chosed this one over those…

And my teacher said it couldn’t be done. Ha, this page shut him up…

Thank you very very very much…
