BERKELEY_DB5.1_SVC(1) General Commands Manual BERKELEY_DB5.1_SVC(1)NAME
berkeley_db5.1_svc - Berkeley DB RPC server
SYNOPSIS
berkeley_db5.1_svc [-Vv] [-h home] [-I seconds] [-L file] [-t seconds] [-T seconds]
DESCRIPTION
The berkeley_db5.1_svc utility is the Berkeley DB RPC server.
OPTIONS -h Add the specified home directory to the list of allowed home directories that can be specified by the client. The home directory
should be an absolute pathname. The last component of each home directory specified must be unique because that is how clients
specify which database environment they want to join.
Recovery will be run on each specified environment before the server begins accepting requests from clients. For this reason, only
one copy of the server program should ever be run at any time because recovery must always be single-threaded.
-I Set the default idle timeout for client environments to the specified number of seconds. The default timeout is 24 hours.
-L Log the execution of the berkeley_db5.1_svc utility to the specified file in the following format, where ### is the process ID, and
the date is the time the utility was started.
berkeley_db5.1_svc: ### Wed Jun 15 01:23:45 EDT 1995
This file will be removed if the berkeley_db5.1_svc utility exits gracefully.
-t Set the default timeout for client resources (idle transactions and cursors) to the specified number of seconds. When the timeout
expires, if the resource is a transaction, it is aborted; if the resource is a cursor, it is closed. The default timeout is 5 min-
utes.
-T Set the maximum timeout allowed for client resources. The default timeout is 20 minutes. If a client application requests a server
timeout greater than the maximum timeout set for this server, the client's timeout will be capped at the maximum timeout value.
-V Write the library version number to the standard output, and exit.
-v Run in verbose mode.
The berkeley_db5.1_svc 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.

db5.1_stat - Display statistics for Berkeley DB environments
SYNOPSIS
db5.1_stat -d file [-fN] [-h home] [-P password] [-s database]
db5.1_stat [-cEelmNrtVZ] [-C Aclop] [-h home] [-L A] [-M A] [-R A] [-P password]
DESCRIPTION
The db5.1_stat utility displays statistics for Berkeley DB environments.
OPTIONS -C Display internal information about the locking subsystem. (The output from this option is often both voluminous and meaningless,
and is intended only for debugging.)
A Display all information.
c Display lock conflict matrix.
l Display lockers within hash chains.
o Display lock objects within hash chains.
p Display locking subsystem parameters.
-c Display locking subsystem statistics, as described in DB_ENV->lock_stat.
-d Display database statistics for the specified file, as described in DB->stat.
If the database contains multiple databases and the -s flag is not specified, the statistics are for the internal database that
describes the other databases the file contains, and not for the file as a whole.
-E Display internal information about the database environment, including all configured subsystems of the database environment. (The
output from this option is often both voluminous and meaningless, and is intended only for debugging.)
-e Display information about the database environment, including all configured subsystems of the database environment.
-f Display only those database statistics that can be acquired without traversing the database.
-h Specify a home directory for the database environment; by default, the current working directory is used.
-l Display logging subsystem statistics, as described in DB_ENV->log_stat.
-M Display internal information about the cache. (The output from this option is often both voluminous and meaningless, and is
intended only for debugging.)
A Display all information.
h Display buffers within hash chains.
-m Display cache statistics, as described in DB_ENV->memp_stat.
-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 Display internal information about the replication subsystem. (The output from this option is often both voluminous and meaning-
less, and is intended only for debugging.)
A Display all information.
-r Display replication statistics, as described in DB_ENV->rep_stat.
-s Display statistics for the specified database contained in the file specified with the -d flag.
-t Display transaction subsystem statistics, as described in DB_ENV->txn_stat.
-V Write the library version number to the standard output, and exit.
-Z Reset the statistics after reporting them; valid only with the -C, -c, -E, -e, -L, -l, -M, -m, -R, -r, and -t options.
Values normally displayed in quantities of bytes are displayed as a combination of gigabytes (GB), megabytes (MB), kilobytes (KB), and
bytes (B). Otherwise, values smaller than 10 million are displayed without any special notation, and values larger than 10 million are
displayed as a number followed by "M".
The db5.1_stat utility may be used with 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, db5.1_stat should always be given the chance to detach from the environment and exit gracefully. To cause
db5.1_stat to release all environment resources and exit cleanly, send it an interrupt signal (SIGINT).
The db5.1_stat 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.
