Supported Platforms

This page describes the supported platforms for JIRA 5.2. If a particular platform's version is not mentioned on this page, then we do not support that version of the platform for JIRA 5.2.

Please also ensure you have read the JIRA Requirements page, since not all the platforms listed below may be required for your specific JIRA setup.

Notes:

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. Atlassian only officially supports JIRA running on x86 hardware and 64-bit derivatives of x86 hardware. If you are installing JIRA from an archive, you should create a dedicated user account on the operating system to run JIRA, since JIRA runs as the user it is invoked under and therefore can potentially be abused.
   
3. Although the JIRA Linux Installer is designed to install successfully on all 'flavours' of Linux, we only test the JIRA Linux Installer on CentOS Linux. If you encounter problems with the JIRA Linux Installer on your particular flavour of Linux, we recommend installing JIRA on Linux from an archive file.
   
4. Deploying multiple Atlassian applications in a single Tomcat container is not supported. Please see Deploying Multiple Atlassian Applications in a Single Tomcat Container for reasons why we do not support this configuration.
   
5. The MySQL driver is no longer bundled with JIRA, as of JIRA 5.2. Please see the JIRA 5.2 Upgrade Notes for reasons why we do not bundle this driver.
   
6. JIRA ships with a built-in database (HyperSQL DataBase or HSQLDB). While this database is suitable for evaluation purposes, it is susceptible to data loss during system crashes. Hence, for production environments we strongly recommend that you configure JIRA to use an external database.
   
7. Please refer to our Security Bugfix Policy on fixing browser issues.  
8. Minimum screen resolution of 1024 x 768 (when these browsers are maximised).
9. 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 above (preferably 5.0), or refer to our Firefox 3.6.0 caveats document for more details about this issue and how to avoid it.
