NAME
db4.7_printlog - Dumps Berkeley DB log files in a human-readable format
SYNOPSIS
db4.7_printlog [-NrV] [-b start-LSN] [-e stop-LSN] [-h home] [-P
password]
DESCRIPTION
The db4.7_printlog utility is a debugging utility that dumps Berkeley
DB log files in a human-readable format.
OPTIONS
-b 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 offset number, with no
intervening whitespace.
-e 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 offset number, with no intervening
whitespace.
-h 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 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.
-P 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 db4.7_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, db4.7_printlog should always be given the chance to detach
from the environment and exit gracefully. To cause db4.7_printlog to
release all environment resources and exit cleanly, send it an
interrupt signal (SIGINT).
The db4.7_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.
