Ticonderoga

Ticonderoga is the primay Moodle database server.  However, since the load required for that task does not seem to taxing the server we are exploring using it for other MySQL databases as well. In particular, some of the Drupal databases from MyCEHD.  Having a single MySQL database would be more efficient for maintenance purposes.  But, we don't want to do anything that will take away from the its primary Moodle tasks.

Ticonderoga runs MySQL almost exclusively.

The moodle databases are replicated

  • binlog_format = 'MIXED'
    • There was a problem with the upgrade process when using the default 'STATEMENT'. The error seems limited to the upgrade process when extra care is being taken to isolate statements. But, we are leaving this as default since it appears to be more robust than the default setting.
