Ledger Recovery using the shell

The following examples show the different ways to use the Ledger Recovery flow from the Corda node shell.

• Run Ledger Recovery for a given time window and using all available nodes in the network:

  flow start LedgerRecoveryFlow timeWindow: { fromTime: "2023-07-19T09:00:00Z", untilTime: "2023-07-19T09:00:00Z" }, useAllNetworkNodes: true
  

• Run Ledger Recovery without actually performing reconciliation (for example, dryRun = true) with detailed record/transaction-level output (verboseLogging = true) for a given time window and using all available nodes in the network:

  flow start LedgerRecoveryFlow timeWindow: { fromTime: "2023-07-19T09:00:00Z", untilTime: "2023-07-19T09:00:00Z" }, dryRun: true, verboseLogging: true, useAllNetworkNodes: true
  

• Run Ledger Recovery for a given time window and specifying a single specific peer recovery node:

  flow start LedgerRecoveryFlow timeWindow: { fromTime: "2023-10-12T19:00:00Z", untilTime: "2023-12-12T22:00:00Z" }, recoveryPeer:  "O=Bank B, L=New York, C=US"
  

• Run Ledger Recovery for a given time window and specifying several peer recovery nodes:

  flow start LedgerRecoveryFlow timeWindow: { fromTime: "2023-10-12T19:00:00Z", untilTime: "2023-12-12T22:00:00Z" }, recoveryPeers: ["O=Bank B, L=New York, C=US", "O=Bank C, L=Chicago, C=US"]
  

• Run Ledger Recovery for a given time window and single peer recovery node, and perform finality flow recovery of any encountered IN_FLIGHT transactions:

  flow start LedgerRecoveryFlow timeWindow: { fromTime: "2023-10-12T19:00:00Z", untilTime: "2023-12-12T22:00:00Z" }, recoveryPeer:  "O=Bank B, L=New York, C=US", alsoFinalize: true
