  1. Confluence is a pure Java application and should run on this platform provided all other JDK requirements are 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. HSQLDB: 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. We do not support editing in Safari on iOS devices (such as iPhone and iPad). Please refer to CONF-19524 for information on the progress of this issue.
