================================ Database administration commands ================================ There are two types of maintenance operations that can be performed through the LaunchPad: * **maintain** - automatically detects and marks failed jobs and deleted queue reservations * **tuneup** - tries to speed up database performance by updating indices and compacting the database. Should be performed during database downtime. Maintain to mark failed jobs and queue reservations =================================================== We recommend that all users periodically run the *maintain* command from the LaunchPad. This will detect failed jobs and queue reservations - for details, refer to the :doc:`failures tutorial ` and :doc:`queue reservation tutorial `. In summary, the command will mark the state of failed jobs as *FIZZLED* and will move any long-waiting *RESERVED* FireWorks back to *READY*. The maintenance command can be run using:: lpad admin maintain If you would like to run maintenance in an infinite loop, you can use:: lpad admin maintain --infinite --maintain_interval 6000 This formulation will run a maintenance job every 6000 seconds (100 minutes). Tuneup to improve performance ============================= You only need to run a database tuneup if you are not satisfied with the performance of FireWorks. The tuneup will update all the indices:: lpad admin tuneup You can do a full tuneup which will block while updating indices and also compact the database. You should only run the full tuneup command during periods of downtime:: lpad admin tuneup --full Force Refresh Workflow ====================== This command should not be needed, but if you would like to force a workflow refresh you can do it via: lpad admin refresh_wf -i where ```` is the id of any one FW in the Workflow you want to refresh. More options are available, use ``lpad admin refresh -h`` for more information.
