DB5.0_PRINTLOG(1)
NAME
db5.0_printlog - Dumps Berkeley DB log files in a human-readable format
SYNOPSIS
db5.0_printlog [-NrV] [-b start-LSN] [-e stop-LSN] [-h home] [-P pass- word]
DESCRIPTION
The db5.0_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 prob
- lems, 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 db5.0_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, db5.0_printlog should always be given the chance to detach from the environment and exit gracefully. To cause db5.0_printlog to release all environment resources and exit cleanly, send it an interrupt signal (SIGINT).
- The db5.0_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.
