Recovering Provisioning Flow

When restarting after a failure or shutdown, use the recover checkpoints command to reload the provisioning flow to its last known checkpoint: 

provadmin recover checkpoints

This recovers:

  • Orders waiting inside order queues and derived order queues such as, drivers or sequencers. Heaps and queues are reconstructed as if the shutdown never happened.

  • Orders in checkpoint modules: Each order is reinjected into the module at the last checkpoint.

Following an application failure, the last known state for an order is the last valid checkpoint. If the application fails while writing a checkpoint, the checkpoint will be invalid. In such cases, the previous checkpoint will be used.
