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
password]
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
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 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 environment,
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 interrupt signal (SIGINT).
The db5.3_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.
