Berkeley DB: db_printlog
db_printlog

db_printlog [-NV] [-h home]
Description
The db_printlog utility is a debugging utility that dumps Berkeley DB
log files in a human-readable format.
The options are as follows:
- -h
- Specify a home directory for the database environment; by
default, the current working directory is used.
- -N
- Do not acquire shared region locks 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.
- -V
- Write the library version number to the standard output, and exit.
For more information on the db_printlog output and using it to
debug applications, see Reviewing
Berkeley DB log files.
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
Berkeley DB environment, db_printlog should always be given the chance to
detach from the environment and exit gracefully. To cause db_printlog
to release all environment resources and exit cleanly, send it an
interrupt signal (SIGINT).
The db_printlog utility exits 0 on success, and >0 if an error occurs.
Environment Variables
- 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.
