{{Fancydancy|'''Please feel free to contribute to this article by adding installation steps for more operating systems or improving existing ones'''.}}

== PostgreSQL database ==
Openbravo ERP supports [http://www.postgresql.org/ PostgreSQL] as its database engine.

* 8.3.5 is the minimum required version.
* The UUID contrib package is required.

PostgreSQL documentation and tutorials are available at:

* [http://www.postgresql.org/docs/ PostgreSQL Documentation]
* [http://www.thegeekstuff.com/2009/04/15-practical-postgresql-database-adminstration-commands/ 15 Practical PostgreSQL Database Administration Commands]

===Installing PostgreSQL on Microsoft Windows ===
Follow the instructions on the [http://wiki.postgresql.org/wiki/Running_%26_Installing_PostgreSQL_On_Native_Windows PostgreSQL wiki]. Make sure to select the "UUID" option during the installation.

There's two installers right now: ''pgInstaller'' and ''One click installer'', We suggest you use '''pgInstaller''' to install PostgreSQL.

By default, '''One click installer''' version does not include the UUID, if you use it you will need to also do this three steps:

#Download "uuid-ossp.dll" from zip file at [http://winpg.jp/~saito/pg_work/OSSP_win32/ winpg.jp]
#Unpack the zip file into ''%Postgresql_directory%/lib'' directory
#Restart the Postgresql server.

=== Installing PostgreSQL on Debian (Ubuntu/Kubuntu/Linux Mint) ===
#Install the package using
#:<pre>sudo apt-get install postgresql-8.3 postgresql-contrib-8.3</pre>
#Set the postgres password using:
#:<pre>sudo /etc/init.d/postgresql-8.3 start
#:sudo su - postgres -c psql
#:alter role postgres with password 'new_password';
#:\q</pre>

===Installing PostgreSQL on Gentoo ===

* The '''number of open cursors''' should be at least '''3000'''. Verify it, and tune the ''ALTER SESSION'' to change the number of open cursors if needed:
<source lang="sql">SELECT value FROM v$parameter WHERE name = 'open_cursors';
ALTER SYSTEM SET open_cursors = 3000 SCOPE=BOTH;</source>
* Make sure that the '''number of processes''' is at least '''150'''. Verify it, and tune the ''ALTER SESSION'' to change the number of processes if needed:
<source lang="sql">SELECT value FROM v$parameter WHERE name = 'processes';
ALTER SYSTEM set processes=150 SCOPE=SPFILE;</source>
* Restart Oracle after doing this change.

== Sun JDK ==
Openbravo supports the following JDKs:

* [http://java.sun.com/ Sun Java Development Kit] version 1.6 (also known as JDK 6.0).
* [http://www.ibm.com/developerworks/java/jdk/ IBM JDK]
* [http://openjdk.java.net/ OpenJDK] version 6 (IcedTea 1.8.x).

All the developers use Sun's version and therefore is the recommended one.

=== Installing the Java SDK on Microsoft Windows ===
#Download and install [http://java.sun.com/javase/downloads/index.jsp JDK 1.6].
#Add the JAVA_HOME environment variable:
## Right-click on '''My Computer'''.
## Select '''Properties'''. The System Properties window appears.
## Select the '''Advanced''' tab then click '''Environment Variables'''.
## Click '''New'''. The New System Variable box appears.
## In the '''Variable name''' field, type ''JAVA_HOME''.

## Select the PATH environment variable.
## In the '''Variable value''' field, type the path of the JDK installation directory's ''bin'' folder. This is usually ''C:\Java\jdk1.6.0_<version>\bin''

===Installing the Java SDK on Debian (Ubuntu/Kubuntu/Linux Mint) ===

You must add unstable/non-free apt repositories to install sun-java-jdk6. Ubuntu/Kubuntu users may also need to add the Multiverse repository to install sun-java6-jdk. The Multiverse repository is enabled by default in version Ubuntu 7.10 onwards.

#Install the package:
#:<pre> sudo apt-get install sun-java6-jdk</pre>
#Set the Sun Java JDK as the default JDK:
#:<pre>sudo update-java-alternatives -s java-6-sun</pre>
#Create the '''JAVA_HOME''' variable:
#:<pre> echo 'JAVA_HOME="/usr/lib/jvm/java-6-sun"' | sudo tee -a /etc/environment</pre>
#To make this variable available in your current terminal run:
#:<pre>source /etc/environment</pre>
#To make these variables available system wide, restart the user session.

===Installing the Java SDK on Gentoo ===
#To install the package:
#:<pre>emerge -av sun-jdk</pre>
#Set the default JDK:
#:<pre>java-config -S sun-jdk-1.6</pre>

Portage sets the '''JAVA_HOME''' variable automatically.

===Installing the Java SDK on CentOS ===

#Download [http://java.sun.com/javase/downloads/index.jsp JDK 1.6], put the file in /tmp/.
#Run the installer as root:
#<pre>su -</pre>
#<pre>sh /tmp/jdk-6uXY-linux-i586.bin</pre>
#<pre>mv /tmp/jdk1.6.0_XY/ /usr/local/sun-jdk</pre>
# Create the required environment variables:
#<pre>echo 'export JAVA_HOME=/usr/local/sun-jdk' > /etc/profile.d/sun-jdk.sh</pre>
#<pre>echo 'export PATH=$JAVA_HOME/bin/:$PATH' >> /etc/profile.d/sun-jdk.sh</pre>
#<pre>chmod +x /etc/profile.d/sun-jdk.sh</pre>
# Now log out and log in again as root:
#<pre>exit</pre>
#<pre>su -</pre>
# Verify that the JDK is working as expected:
#:<pre>echo $JAVA_HOME</pre>
#:<pre>/usr/local/sun-jdk</pre>
#:<pre>java -version</pre>
#:<pre>java version "1.6.0_18"</pre>
#:<pre>Java(TM) SE Runtime Environment (build 1.6.0_18-b07)</pre>

== Apache Tomcat ==
Openbravo ERP recommends [http://tomcat.apache.org/ Apache Tomcat] version 6.0 as the servlet container. Use the tar and not the Installer.

===Installing Apache Tomcat on Microsoft Windows ===

##Click '''OK'''.
##Click '''New'''. The New User Variable box appears.
##In the '''Variable name''' field, type ''CATALINA_BASE''.
##In the '''Variable value''' field type the path of the Apache Tomcat installation directory.
##Click '''OK'''
##Click '''New'''. The New User Variable box appears.
## In the '''Variable name''' field, type ''CATALINA_OPTS''.
##In the '''Variable value''' type ''-server -Xms384M -Xmx512M -XX:MaxPermSize=256M''.
### If you want to be able to install modules and update the core from the repository, we recommend setting the ''CATALINA_OPTS'' to ''-server -Xms384M -Xmx1024M -XX:MaxPermSize=256M''
##Select the ''PATH'' environment variable.
##In the '''Variable value''' field, type the path of the Apache Tomcat installation's ''bin'' folder. This is usually ''C:\Apache Software Foundation\Tomcat 6.0\bin''.
{{(!)| More information about managing environment variables in Microsoft's [http://support.microsoft.com/kb/310519 Help & Support] site}}
#Copy the ''C:\Java\jdk1.6.0_<version>\bin\lib\tools.jar'' file from your Sun JDK installation to ''C:\Apache Software Foundation\Tomcat 6.0\lib\''
#In order to avoid Tomcat from auto-reloading itself, comment the WatchedResource line in ''C:\Apache Software Foundation\Tomcat 6.0\conf\context.xml'':
#:<source lang="xml"></source>
#Configure a username and password for the Tomcat Manager, by replacing the ''C:\Apache Software Foundation\Tomcat 6.0\conf\tomcat-users.xml'' file with these contents, replacing password="admin" with your chosen password:

<source lang="xml"><?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="manager"/>
<role rolename="admin"/>
<user username="admin" password="admin" roles="admin,manager"/>
</tomcat-users>
</source>

You can check that Tomcat is running by opening http://localhost:8080 in a web browser.

===Installing Apache Tomcat on Debian (Ubuntu/Kubuntu/Linux Mint) ===
#Install the package:
#:<pre> sudo apt-get install tomcat6 tomcat6-admin
#: sudo rm /var/log/tomcat6/catalina.out
#: sudo /etc/init.d/tomcat6 start</pre>
#:'''Note''': On Ubuntu the 'sudo rm /var/log/tomcat6/catalina.out' command may not find the file, resulting in an error message. This will not affect the installation.
#Check that Tomcat is running by opening http://localhost:8080 in a web browser. Alternatively use the following nmap command to check that port 8080 is open:
#:<pre> nmap localhost -p 8080</pre> if you don't have installed nmap you can try <pre>sudo netstat -atunep|grep 8080|grep jsvc</pre>
#:'''Note''': Earlier versions of Debian based distributions configured Tomcat to run on port 8180. If you cannot verify that Tomcat is running on port 8080, please try 8180 instead.
#Set the '''CATALINA_HOME''', '''CATALINA_BASE''' and '''CATALINA_OPTS''' variables:
#:<pre>echo 'CATALINA_HOME="/usr/share/tomcat6"' | sudo tee -a /etc/environment
#: echo 'CATALINA_BASE="/var/lib/tomcat6"' | sudo tee -a /etc/environment</pre>
#Edit the /etc/default/tomcat6 file, and set the following line:-
#:<pre>JAVA_OPTS="-server -Djava.awt.headless=true -Xms384M -Xmx512M -XX:MaxPermSize=256M"</pre>
#To make this variable available in your current terminal run:
#:<pre>source /etc/environment</pre>
#To make these variables available system wide, restart the user session.
#Check if the tools.jar library is present in Tomcat's classpath in directory /usr/share/tomcat6/lib and, if not, add it:
#:<pre>cp $JAVA_HOME/lib/tools.jar /usr/share/tomcat6/lib/</pre>
#:In order to avoid Tomcat from auto-reloading itself, comment the WatchedResource line in /var/lib/tomcat6/conf/context.xml:
#:<source lang="xml"></source>
#Configure a username and password for the Tomcat Manager, by replacing the ''/etc/tomcat6/tomcat-users.xml'' file with these contents, replacing password="admin" with your chosen password:
#:<source lang="xml"><?xml version='1.0' encoding='utf-8'?>
#:<tomcat-users>
#: <role rolename="manager"/>
#: <role rolename="admin"/>
#: <user username="admin" password="admin" roles="admin,manager"/>
#:</tomcat-users></source>
#Starting with 2.50, the modularity feature required the tomcat user to write in the main Openbravo ERP directory. So achieve this, edit the /etc/init.d/tomcat6 file, search for ''umask 022'' and replace it with ''umask 002''. Then restart Tomcat.

{{Fancydancy|'''Important notes''':
* The security policy of Debian's Tomcat package will prevent the Openbravo context from loading. You must either disable the security policy or create a rule to allow the Openbravo context to load.
*#To create a rule for Openbravo you must create a .policy file. Use a command like:
*#:<pre> sudo touch /etc/tomcat6/policy.d/20openbravo.policy</pre>
*#:to create a file called ''/etc/tomcat5.5/policy.d/20openbravo.policy''.
*#Open the file and add the following contents:
*#:<pre> // permissions for Openbravo ERP
*#: grant codeBase "file:${catalina.base}/webapps/openbravo/-" {
*#: permission java.security.AllPermission;
*#: };</pre>
*#Save the file.
*#Restart tomcat to make the changes effective.
*#:<pre> sudo /etc/init.d/tomcat6 restart</pre>}}

===Tomcat through a proxy===
If your network have a proxy, you need to append this to the tomcat configuration:

CATALINA_OPTS='-Dhttp.proxySet=true -Dhttp.proxyHost=[PROXY SERVER] -Dhttp.proxyPort=[PORT]'

== Apache Ant ==
[http://ant.apache.org/ Apache Ant] is a Java-based build tool used by Openbravo ERP to automate most of its development tasks. Version 1.7.0 or higher is required.
{{(!)|Note: Apache Ant 1.8.x has not been tested. Use the latest 1.7.x}}

===Installing Apache Ant on Microsoft Windows ===
#Download and extract [http://ant.apache.org/bindownload.cgi Apache Ant] ([http://archive.apache.org/dist/ant/binaries/ old releases]) onto your system (for instance, ''C:\Apache-Ant'').
#Add '''ANT_HOME''' environment variable:
##Right-click on '''My Computer'''.
##Select '''Properties'''. The System Properties window appears.
##Select the '''Advanced''' tab.
##Click on the '''Environment Variables''' button.
##Click the '''New''' button.
##In the '''Variable name''' field, type ''ANT_HOME''.
##In the '''Variable value''' field, type the path of the Ant directory. This is usually ''C:\Apache-Ant''.
##Click '''OK'''.
## Select the ''PATH'' environment variable.
##In the Variable value field, type the path of the Ant directory's ''bin'' folder. This is usually ''C:\Apache-Ant\bin''.
#Equally add the '''ANT_OPTS''' environment variable:
##Click the '''New''' button.
##In the '''Variable name''' field, type ''ANT_OPTS''.
##In the '''Variable value''' field, type ''-Xmx1024M -XX:MaxPermSize=128M''.

===Installing Apache Ant on Debian (Ubuntu/Kubuntu/Linux Mint) ===
#Install the package:
#:<pre>sudo apt-get install ant ant-optional</pre>
#Set the '''ANT_HOME''' variable:
#:<pre>echo 'ANT_HOME="/usr/share/ant"' | sudo tee -a /etc/environment</pre>
#Set the '''ANT_OPTS''' variable:
#:<pre>echo 'ANT_OPTS="-Xmx1024M -XX:MaxPermSize=128M"' | sudo tee -a /etc/environment</pre>
#Make the ANT_HOME and ANT_OPTS variables available in your current terminal run:
#:<pre>source /etc/environment</pre>
#To make the variables available system wide, restart the user session.

===Installing Apache Ant on Gentoo ===
In Gentoo it's enough to install the ant-core package:

emerge -av dev-java/ant-core

Portage sets the '''ANT_HOME''' variable automatically. But not '''ANT_OPTS'''. To set it:

echo 'ANT_OPTS="-Xmx1024M -XX:MaxPermSize=128M"' > /etc/env.d/99ant
env-update && source /etc/profile

To make the variables available system wide, restart the user session.

===Installing Apache Ant on CentOS===

#Download and extract [http://archive.apache.org/dist/ant/binaries/apache-ant-1.7.1-bin.tar.gz Apache Ant] 1.7.1 onto your system:
#:<pre>su -</pre>
#:<pre>cd /tmp</pre>
#:<pre>wget http://archive.apache.org/dist/ant/binaries/apache-ant-1.7.1-bin.tar.gz</pre>
#:<pre>cd /usr/local</pre>
#:<pre>tar zxvf /tmp/apache-ant-1.7.1-bin.tar.gz</pre>
#:<pre>mv apache-ant-1.7.1/ ant</pre>
#Add the environment variables:
#:<pre>echo 'export ANT_HOME=/usr/local/ant' > /etc/profile.d/ant.sh</pre>
#:<pre>echo 'export PATH=$ANT_HOME/bin/:$PATH' >> /etc/profile.d/ant.sh</pre>
#:<pre>echo 'export ANT_OPTS="-Xmx1024M -XX:MaxPermSize=128M"' >> /etc/profile.d/ant.sh</pre>
#:<pre>chmod +x /etc/profile.d/ant.sh</pre>
# Now log out and log in again as root:
#<pre>exit</pre>
#<pre>su -</pre>
# Verify that Ant working as expected:
#<pre>ant -version</pre>
#<pre>Apache Ant version 1.7.1 compiled on June 27 2008</pre>

== Operating system permissions for Tomcat ==
UNIX based operating systems use different system users to run their processes and services. Tomcat usually has its own ''tomcat'' user, and a command line and task is run by a normal user, e.g. ''openbravo''. Since the introduction of the modularity feature in version 2.50, it is necessary to allow ''tomcat'' to write in the root directory of the Openbravo ERP installation. Conversely, the ''openbravo'' user requires write permissions in the Tomcat webapps directory.

#Change the default file permissions for the user running the Ant tasks, e.g. ''openbravo''. Assuming you are using Bash as your shell, append the following line to the /home/openbravo/.bashrc file:
#:<pre>umask 002</pre>
#Add openbravo to the tomcat group:
#:<pre>gpasswd -a openbravo tomcat</pre>
#Add tomcat to the openbravo group:
#:<pre>gpasswd -a tomcat openbravo</pre>

=== Jasper Reports ===
In some configurations to make JasperReports work, you need to add ''-Djava.awt.headless=true'' parameter to the ''CATALINA_OPTS'' environment variable. The ''CATALINA_OPTS'' should look something similar to ''CATALINA_OPTS ="-server -Xms384M -Xmx512M -Djava.awt.headless=true"''.

=== Tomcat hot-deployment problem on Windows ===
There is a known issue with Tomcat working under Windows. Openbravo ERP does a hot-deploy a of ''openbravo.war'' file to Tomcat but on Windows it often encounters file locking issues. Windows will not let Tomcat undeploy the old application because files are locked by the Operating System. Tomcat has mechanisms to allow avoiding locking. In Tomcat 5.5 and 6.0, this mechanism is disabled by default. To enable it edit %CATALINA_BASE%\conf\context.xml. Find the root <context> and add these two attributes:

<context antiJARLocking="true" antiResourceLocking="true" />
