  1. JIRA is a pure Java-based application and should run on any supported operating system, provided that the JDK / JRE requirements are satisfied.
  2. A dedicated user should be created to run JIRA, as JIRA runs as the user it is invoked under and therefore can potentially be abused. Here is an example of how to create a dedicated user to run JIRA in Linux/Solaris:

    $ sudo /usr/sbin/useradd --create-home --home-dir /usr/local/jira --shell /bin/bash jira

  3. Deploying multiple Atlassian applications in a single Tomcat container is not supported. We do not test this configuration and upgrading any of the applications (even for point releases) is likely to break it. There are also a number of known issues with this configuration (see this FAQ for more information).

    We also strongly recommend that you do not deploy multiple Atlassian applications in a single Tomcat container for a number of practical reasons. Firstly, you will need to shut down Tomcat to upgrade any application and secondly, if one application crashes, the other applications running in the Tomcat container will be inaccessible.

  4. JIRA ships with a built-in HSQL database, which is fine for evaluation purposes but is somewhat susceptible to data loss during system crashes. For production environments we recommend that you configure JIRA to use an external database.
  5. Minimum screen resolution of 1024 x 768 (when these browsers are maximised).
  6. Firefox version 3.6.0 possesses a bug that could result in data loss when used with JIRA. If you use this version of Firefox, please either upgrade your version of Firefox to 3.6.2 or refer to our Firefox 3.6.0 caveats document for more details about this issue and how to avoid it.
