Restoring State Keepers
For more information about where to locate the nodes that contain a checkpoint’s metadata subdirectory and the state keeper recovery file, see the section, Checkpoints. The state keeper recovery file is named statekeeper-recovery.
Before you begin When restoring your state keepers, ensure that the same checkpoint recovery file is used when restarting each state keeper. To restore your state keepers from a checkpoint recovery file, ensure that you complete the following steps.
- Ensure that the realm services have been restored as described in the sectionRealm Service Checkpoint Restore.
- Ensure that all state keepers are stopped.
- Procedure
- Locate the statekeeper-recovery file associated with the checkpoint that you want to restore the state keeper from. Note its path.
- Restart all state keepers by using the same version of the recovery file. Use the --recovery-file or -R command-line options.
tibdgkeeper -r <realm service URL> -n <state keeper name> --recovery-file <path to statekeeper-recovery file>
The same command can be used to restore a single state keeper or each state keeper of a fault tolerant set of state keepers.
