1. System Requirements

Hardware Requirements

The hardware required to run Crowd depends significantly on the number of applications and users that your installation will have, as well as the maximum number of concurrent requests that the system will experience during peak hours.

During evaluation Crowd will run well on any reasonably fast workstation computer (eg. 1.5+Ghz processor). Memory requirements depend on how many applications and users you will store, but 256MB is enough for most evaluation purposes.

Most users start by downloading Crowd, and running it on their local computer. It is easy to migrate Crowd to your enterprise infrastructure later.

We would appreciate if you let us know what hardware configuration works for you. Please create a support request in JIRA with your hardware specification and mention the number of applications and users in your Crowd installation.

Software Requirements

1. Sun JDK 1.4 (1.5 or higher is preferred). NOTE: Once the JDK is installed, you will need to set the JAVA_HOME environment variable, pointing to the root directory of the JDK. Some JDK installers set this automatically (check by typing 'echo %JAVA_HOME%' in a DOS prompt, or 'echo $JAVA_HOME' in a shell). If it is not set, please see 1.1 Setting JAVA_HOME.
2. J2EE 1.4 application server or a Servlet 2.3 web container. NOTE: Crowd ships with Apache Tomcat (5.5.x).
3. JDBC-compliant database that is supported by Hibernate. NOTE: Crowd ships with a built-in HSQL database, which is fine for evaulation purposes. For production environments we recommend configuring Crowd to use an external database. 

Supported Databases

The following database servers are supported by Hibernate:

• HypersonicSQL
• PostgreSQL
• Microsoft SQL Server
• MySQL
• Oracle 10g (tested on 10.2.0.1)

Of these, the following databases have been tested and are supported by Atlassian:

• 2.1.1 HSQL DB
• 2.1.2 MS SQL Server
• 2.1.3 MySQL
• 2.1.4 Oracle
• 2.1.5 PostgreSQL

Supported J2EE Servers

The following J2EE servers are supported:

• JBoss (4.2.2 GA)
• Resin (3.0.x) - tested on 3.0.23
• Tomcat (5.5.x) - tested on 5.5.20
