Confluence 3.5.9 Upgrade Notes

Below are some important notes on upgrading to Confluence 3.5.9. For details of the fixes in this release, please read the release notes.
As of Confluence 3.5.9, the queue that backs the re-indexing workers has been improved to remove contention. This means two important changes.

  1. Re-indexing is now more CPU-bound. This means that if you had previously adjusted the indexing thread count you may want to revisit that number as it can put significant load on your server if this number is too high.
  2. Each thread will make use of a connection to the database. If the number of threads are configured to a high number this means that there will be a significantly bigger load on the database.

Upgrade Procedure

If you are already running a version of Confluence, please follow these instructions to upgrade to the latest version:

  1. Before you upgrade, we strongly recommend that you back up your Confluence Home directory and database. The Confluence Home directory is the folder where Confluence stores its configuration information, search indexes and page attachments. Another term for 'Home directory' would be 'data directory'. Read more about finding your Home directory.
  2. If your version of Confluence is earlier than 3.5, read the release notes and upgrade guides for all releases between your version and the latest version. In particular:
  3. Download the latest version of Confluence.
  4. Follow the instructions in the Upgrade Guide.
