db_printlog

db_printlog [-NrV] [-b start-LSN] [-e stop-LSN] [-h home] [-P password]  

The db_printlog utility is a debugging utility that dumps Berkeley DB log files in a human-readable format.

Note

If the application(s) that use the environment make use of the DB_ENV->set_lg_dir() method, then in order for this utility to run correctly, you need a DB_CONFIG file which sets the proper paths using the set_lg_dir configuration parameter.

The options are as follows:

For more information on the db_printlog output and using it to debug applications, see Reviewing Berkeley DB log files.

The db_printlog utility uses a Berkeley DB environment (as described for the -h option, the environment variable DB_HOME, or because the utility was run in a directory containing a Berkeley DB environment). In order to avoid environment corruption when using a Berkeley DB environment, db_printlog should always be given the chance to detach from the environment and exit gracefully. To cause db_printlog to release all environment resources and exit cleanly, send it an interrupt signal (SIGINT).

The db_printlog utility exits 0 on success, and >0 if an error occurs.

Environment Variables

DB_HOME

If the -h option is not specified and the environment variable DB_HOME is set, it is used as the path of the database home, as described in the DB_ENV->open() method.
