Home directory and database build number mismatch in Confluence 5.1.x after a site restore (NOT after an upgrade)

    XMLWordPrintable

    Details

      Description

      Since CONF-13798, we store the build number in the database and prevent Confluence from starting up when the home directory and database build numbers don't match.

      When a site restore is performed, the build number in the database is replaced with the value from the backup. When the backup is from a different version, this will prevent the next application startup with the error message:

      Confluence will not start up because the build number in the home directory [...] doesn't match the build number in the database [...].
      

      Fix

      Starting from version 5.1.5, the history of Confluence upgrades will no longer be included in a site backup. This means that backups created from 5.1.5 or later should no longer encounter this issue.

      Restoring a backup that was created prior to 5.1.5 into any version of Confluence that is newer than 5.1.2 will still trigger this error, and the following workaround should be followed.

      Workaround

      Important - Do NOT perform this workaround if the above error was encountered during an upgrade of Confluence (see the description of CONF-13798 for an explanation). If you are seeing this error during or shortly after an upgrade of Confluence, follow the instructions in this document to resolve it.

      If you are restoring an XML backup

      Workaround is to clear the build number from the database - it will be repopulated from the home directory at startup:

      1. Shutdown Confluence
      2. Backup your Confluence database!
      3. Run the following SQL query on the database:

      DELETE FROM confversion;
