db_printlog(1) General Commands Manual db_printlog(1)
db_printlog [-NrV] [-h home] [-P password]
The db_printlog utility is a debugging utility that dumps Berkeley DB log
files in a human-readable format.
The options are as follows:
Specify a home directory for the database environment; by default, the
current working directory is used.
Do not acquire shared region mutexes while running. Other problems, such
as potentially fatal errors in Berkeley DB, will be ignored as well. This
option is intended only for debugging errors, and should not be used
under any other circumstances.
Specify an environment password. Although Berkeley DB utilities overwrite
password strings as soon as possible, be aware there may be a window of
vulnerability on systems where unprivileged users can see command-line
arguments or where utilities are not able to overwrite the memory
containing the command-line arguments.
Read the log files in reverse order.
Write the library version number to the standard output, and exit.
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.
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 DB_ENV->open.
