DB5.3_PRINTLOG(1) General Commands Manual DB5.3_PRINTLOG(1)
NAME
db5.3_printlog - Dumps Berkeley DB log files in a human-readable format
SYNOPSIS
db5.3_printlog [-NrV] [-b start-LSN] [-e stop-LSN] [-h home] [-P pass-
word]
DESCRIPTION
The db5.3_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 in-
tervening 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 de-
fault, the current working directory is used.
-N Do not acquire shared region mutexes while running. Other prob-
lems, such as potentially fatal errors in Berkeley DB, will be
ignored as well. This option is intended only for debugging er-
rors, 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 argu-
ments.
-r Read the log files in reverse order.
-V Write the library version number to the standard output, and
exit.
The db5.3_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 envi-
ronment, db5.3_printlog should always be given the chance to detach
from the environment and exit gracefully. To cause db5.3_printlog to
release all environment resources and exit cleanly, send it an inter-
rupt signal (SIGINT).
The db5.3_printlog utility exits 0 on success, and >0 if an error oc-
curs.
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.
