utility

The db_archive utility supports database backup and archival, and log file administration. It facilitates log reclamation and the creation of database snapshots. Generally, some form of log archival must be done if a database environment has been configured for logging or transactions.

utility

The db_checkpoint utility runs as a daemon process, monitoring the database log and periodically issuing checkpoints. It facilitates log reclamation and the creation of database snapshots. Generally, some form of database checkpointing must be done if a database environment has been configured for transactions.

utility

The db_deadlock utility runs as a daemon process, periodically traversing the database lock structures and aborting transactions when it detects a deadlock. Generally, some form of deadlock detection must be done if a database environment has been configured for locking.

utility

db_hotbackup utility

The utility creates “hot backup” or “hot failover” snapshots of Berkeley DB database environments.

db_load utility

The utility reads the flat-text file produced by the db_load utility and loads it into a database file.

utility

The db_printlog utility displays the contents of Berkeley DB log files in a human-readable and parsable format.

utility

db_stat utility

The utility displays statistics for databases and database environments.

db_tuner utility

The utility suggests a page size for btree databases that optimizes cache efficiency and storage space requirements.

db_upgrade utility

The utility provides a command-line interface for upgrading underlying database formats.

db_verify utility

All of the functionality implemented for these utilities is also available as part of the standard Berkeley DB API. This means that threaded applications can easily create a thread that calls the same Berkeley DB functions as do the utilities. This often simplifies an application environment by removing the necessity for multiple processes to negotiate database and database environment creation and shut down.
