NAME
dbwraptool - low level TDB/CTDB manipulation tool using the dbwrap interface SYNOPSIS
dbwraptool [persistent] [non-persistent] [-d
] [-s
] [-l ] [-V] [option= = ] { } { } [ [ [ ]]] DESCRIPTION This tool is part of the samba(7) suite. The dbwraptool 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") OPTIONS persistent Open the database as a persistent database. Exactly one of persistent and non-persistent must be specified.
non-persistent
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.
-d|debuglevel=level 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.
-V|version Prints the program version number.
-s|configfile=
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.
-l|log-basename=logdirectory 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. option=
= Set the smb.conf(5) option " " to value " " from the command line. This overrides compiled-in defaults and options read from the configuration file.
-?|help Print a summary of command line options. usage Display brief usage message. COMMANDS fetch dbwraptool
