DB_PRINTLOG(1) BerkeleyDB Utilities DB_PRINTLOG(1)
NAME
db_printlog - Dumps log files into a human-readable format
SYNOPSIS
db_printlog [-NrV] [-b start-LSN] [-e stop-LSN] [-h home] [-P password]
DESCRIPTION
The db_printlog utility is a debugging utility that dumps Berkeley DB log files in a
human-readable format.
OPTIONS
-b start-LSN
Display log records starting at log sequence number (LSN) start-LSN; start-LSN is
specified as a file number, followed by a slash (/) character, followed by an off-
set number, with no intervening whitespace.
-e stop-LSN
Stop displaying log records at log sequence number (LSN) stop-LSN; stop-LSN is
specified as a file number, followed by a slash (/) character, followed by an off-
set number, with no intervening whitespace.
-h home
Specify a home directory for the database environment; by default, the current
working directory is used.
-N Do not acquire shared region mutexes while running. Other problems, such as poten-
tially 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 circum-
stances.
-P password
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.
-r Read the log files in reverse order.
-V Write the library version number to the standard output, and exit.
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 Berke-
ley DB environment, db_printlog should always be given the chance to detach from the envi-
ronment and exit gracefully. To cause db_printlog to release all environment resources
and exit cleanly, send it an interrupt signal (SIGINT).
EXIT STATUS
The db_printlog utility exits 0 on success, and >0 if an error occurs.
ENVIRONMENT
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.
NOTES
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.
