dbwrap_tool — low level TDB/CTDB manipulation tool using the dbwrap interface
dbwrap_tool [--persistent] [--non-persistent] [-d <debug level>] [-s <config file>] [-l <log file base>] [-V] [--option=<name>=<value>] {<database>} {<operation>} [<key>
[<type>
[<value>]]]
This tool is part of the samba(7) suite.
The dbwrap_tool program is used to read and manipulate TDB/CTDB databases using the dbwrap interface.
The following database operations are available:
fetch: fetch a record
store: create or modify a record
delete: remove a record
exists: test for existence of a record
erase: remove all records
listkeys: list all available records
listwatchers: list processes, which are waiting for changes in a record
The following types are available:
int32: signed 32bit integer
uint32: unsigned 32bit integer
string: "hello world"
hex: hex strings like "68656C6C6F20776F726C6400" ("hello world")
Open the database as a persistent database.
Exactly one of --persistent and --non-persistent must be specified.
Open the database as a non-persistent database.
Caveat: opening a database as non-persistent when there is currently no other opener will wipe the database.
Exactly one of --persistent and --non-persistent must be specified.
level is an integer
from 0 to 10. The default value if this parameter is
not specified is 1.
The higher this value, the more detail will be logged to the log files about the activities of the server. At level 0, only critical errors and serious warnings will be logged. Level 1 is a reasonable level for day-to-day running - it generates a small amount of information about operations carried out.
Levels above 1 will generate considerable amounts of log data, and should only be used when investigating a problem. Levels above 3 are designed for use only by developers and generate HUGE amounts of log data, most of which is extremely cryptic.
Note that specifying this parameter here will
override the log level parameter
in the smb.conf file.
Prints the program version number.
The file specified contains the
configuration details required by the server. The
information in this file includes server-specific
information such as what printcap file to use, as well
as descriptions of all the services that the server is
to provide. See smb.conf for more information.
The default configuration file name is determined at
compile time.
Base directory name for log/debug files. The extension
".progname" will be appended (e.g. log.smbclient,
log.smbd, etc...). The log file is never removed by the client.
Set the smb.conf(5) option "<name>" to value "<value>" from the command line. This overrides compiled-in defaults and options read from the configuration file.
Print a summary of command line options.
Display brief usage message.
