db_checkpoint
NAME
db_checkpoint - the DB database checkpoint utility
SYNOPSIS
db_checkpoint [-v] [-h home] [-k kbytes] [-L file] [-p min]
DESCRIPTION
The db_checkpoint utility is a daemon process that moni-
tors the database log and periodically calls txn_check-
point(3) to checkpoint to the database.
The options are as follows:
-h Specify a home directory for the database.
-k Checkpoint the database at least as often as every
kbytes of log file are written.
-L Log the execution of the db_checkpoint utility to the
specified file in the following format, where ``###''
is the process ID, and the date is the time the util-
ity starting running.
db_checkpoint: ### Wed Jun 15 01:23:45 EDT 1995
This file will be removed if the db_checkpoint util-
ity exits gracefully.
-p Checkpoint the database at least every min minutes.
-v Write the time of each checkpoint to the standard
output.
At least one of the -k and -p options must be specified.
The db_checkpoint utility attaches to DB shared memory
regions. In order to avoid region corruption, it should
always be given the chance to detach and exit gracefully.
To cause db_checkpoint to clean up after itself and exit,
send it an interrupt signal (SIGINT).
The db_checkpoint utility exits 0 on success, and >0 if an
error occurs.
ENVIRONMENT VARIABLES
The following environment variables affect the execution
of db_checkpoint:
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_appinit(3).
