This documentation relates to an old version of Nuxeo DAM (1.x). You may want to check the documentation for our latest LTS version and Fast Track version.

Nuxeo DAM runs in a large variety of technical environments. The following list delineates the currently working systems for the installation and operation of Nuxeo DAM. Below is the list of required and recommanded environments:


All you need for a quick start is a Sun Java Development Kit (JDK) (a JRE is not enough). As of Nuxeo EP 5.4 and the applications based on it such as Nuxeo DM 5.4 or Nuxeo DAM 1.2, Java 6 (also called Java 1.6) is required.


We currently support Sun's JDK, don't hesitate to contact us if you need us to support a JDK from another vendor.

Check your Java version

To check that you have the right version of Java
  1. Open a terminal:
    • on Linux or Mac OS X: open a terminal.
    • on Windows: press "windows" key + r, type "cmd" (or "command') in the run window and press "OK" or open the "Prompt command" from "Start > Programs > Accessories" menu.
  2. Type "java -version" and press "Enter".
    If Java is correctly installed on your computer, the name and version of your Java virtual machine is displayed:
    If Java is not installed on you computer, it fails to display the Java version. Then, you need to install Java (see below).
    If Java is installed but not included in the PATH, it fails to find the Java command. Then, you need to add $JAVA_HOME/bin/ in your PATH (see How do I set or change the PATH system variable?).

Install Java

For Windows users

If the required version of Java is not installed on your computer:
  1. Download it from Sun website and choose the appropriate platform for your hardware and Windows version.
  2. Run the downloaded .exe file and follow the instructions displayed.

For Linux users

On a modern Linux distribution, you can now install Sun Java 6 with the packaging system of your distribution (using rpm, apt, yum, etc.).

If the JDK from Sun is not available for your OS, you can still download it from Sun website.


Since Ubuntu 10.4 (Lucid Lynx), sun-java-6 is available from partners software sources (apt repositories).

For Mac OS users

An appropriate version of Java should already be installed on your computer if you are using Snow Leopard (Java 6).


Hardware recommendations

Nuxeo applications are designed to be scalable and can thus to be deployed on many servers. They can be installed on only one server for a start, and can also easily be installed on many servers. The constant is that there is the need to have one modern server with good performances. Then the other servers can be more lower-end.

So the numbers below are given for the one needed high-end server.

  • RAM: 2 GB is the minimum requirement for using Nuxeo,
  • CPU: Intel Core 2 or equivalent and better.
    You might want to avoid machines from the Intel Pentium 4 Xeon series since some models have a too small amount of cache. This impairs performance greatly compared to other CPU architecture of the same generation. (Intel Pentium 4 servers are quite widespread because of an attractive price policy.)
  • Storage (disk) space: the minimum Nuxeo installation, along with the needed server and libs, takes something between 200 MB and 280 MB on a filesystem. Then, the final size will of course depend on the amount of data that will be stored in Nuxeo. A safe bet (until we provide better numbers) is to consider data space ratio of 1.5 GB to 2 GB.

Default configuration

The default persistence configuration is lightweight and easy to use, but it is not made for performance.

Nuxeo DAM uses:

  • H2 for SQL Data (directories, JBPM, Relations ...),
  • Filesystem persistence with VCS for the Document repository.

For optimal performances

  • Linux 64 bits,
  • PostgreSQL 8.4 or 9.0,
    Use PostgreSQL for document repository and all other services.

    With Nuxeo EP 5.1 or 5.2, configure the document repository to externalize the blobs to filesystem.

  • Have plenty of RAM (>= 4 GB).

Known working configurations


  • Debian GNU/Linux 5.0 Lenny
  • Linux Ubuntu 32 and 64 bits: Edgy Eft (6.10), Feisty Fawn (7.04), Gutsy Gibon (7.10), Hardy Heron (8.04 LTS), Intrepid Ibex (8.10), Jaunty Jackalope (9.04), Karmic Koala (9.10), Lucid Lynx (10.04 LTS), Maverick Meerkat (10.10).
  • Linux Mandriva 2008.1
  • Unix
  • Mac OS X Leopard (10.5), Snow Leopard (10.6)
  • Microsoft Windows 2000, Windows 2003 server 32 and 64 bits, Windows XP, Windows 7


  • Sun JDK 6, 64 bits recommended especially on Windows environment.

Storage backends

Different backends may be set as well for Nuxeo Core repository as for all other Nuxeo services that persist data. Here is a list of known working backends:

  • PostgreSQL 8.3, 8.4 or 9.0
  • MySQL 5.1
  • Oracle 10g R2 ( or 11g R2 (
  • Microsoft SQL Server 2005
  • H2 (this is the default embedded database)


  • OpenLDAP
  • OpenDS
  • Microsoft Active Directory
