  1. Confluence is a pure Java application and should run on this platform provided the JRE or JDK requirement is satisfied. 
  2. While some of our customers run Confluence on SPARC-based hardware, Atlassian only officially supports Confluence running on x86 hardware and 64-bit derivatives of x86 hardware.
  3. Ensure that you configure your Confluence MySQL database to use the InnoDB storage engine as the MyISAM storage engine could lead to data corruption. 
  4. Confluence ships with a built-in HSQL database. While this database is fine for evaluation purposes, it is somewhat susceptible to data loss during system crashes. Hence, for production environments, we recommend that you configure Confluence to use an external database
  5. Internet Explorer 9 does not support the drag-and-drop functionality of HTML5. As Confluence relies on this functionality, the drag-and-drop experience in Internet Explorer 9 is not complete. Internet Explorer 10 in 'desktop' mode does support the drag-and-drop functionality, and the implementation of drag-and-drop in Confluence works as expected with Internet Explorer 10 'desktop' mode. The 'modern' mode of Internet Explorer 10 does not support drag-and-drop.
  6. Confluence is tested with these versions of Internet Explorer in standards-compliant rendering mode, not compatibility mode. Enabling compatibility mode may cause problems because it emulates older, unsupported rendering modes.
  7. Chrome does not have WEBDAV / plugin support so features such as Edit in Word for attachments will not work. Please refer to CONF-23322 for information on the progress of the issue.
  8. Confluence does not support editing in Mobile Safari on iOS devices (such as iPhone and iPad). Please refer to CONF-19523 for information on the progress of this issue.
  9. Confluence does not support editing on Android devices.
  10. NFS mounts are not supported on Linux operating systems due to Lucene requirements.
