6 tracker-store - database indexer and query daemon
7
10 tracker-store [OPTION...]
11
14 tracker-store provides both a powerful database daemon which allows
15 clients to query or update their data using the highly descriptive
16 SPARQL language.
17 tracker-store does not do any file crawling or any mining of data
19 itself, instead other processes do that while tracker-store serves as a
20 daemon waiting for such requests from application miners like tracker-
21 miner-fs.
22
25 -?, --help
26 A brief help message including some examples.
27 -V, --version
29 Returns the version of this binary.
30 -v, --verbosity={0|1|2|3}
32 Sets the logging level, 0=errors, 1=minimal, 2=detailed,
33 3=debug.
34 -r, --force-reindex
36 This forces tracker-store to remove databases and to recreate
37 fresh databases ready for data insertion from the miners. For
38 more information about the miners, see tracker-miner-fs.
39 -n, --readonly-mode
41 This starts tracker-store in a mode which disables writing to
42 the database. Only SPARQL read requests can be serviced if this
43 option is used.

47 TRACKER_DB_ONTOLOGIES_DIR
48 This is the directory which tracker uses to load the .ontology
49 files from. If unset it will default to the correct place. This
50 is used mainly for testing purposes.
51 TRACKER_LANGUAGE_STOP_WORDS_DIR
54 This is the directory which tracker uses to load the stop words
55 dictionaries from. If unset it will default to the correct
56 place. This is used mainly for testing purposes.
57 TRACKER_STORE_MAX_TASK_TIME
60 This is maximum time allowed for a process to finish before
61 interruption happens. The actual moment of interruption depends
62 also on the frequency of checks. The value 0 indicates no inter‐
63 ruption. This environment variable is used mainly for testing
64 purposes.
65 TRACKER_STORE_SELECT_CACHE_SIZE / TRACKER_STORE_UPDATE_CACHE_SIZE
68 Tracker caches database statements which occur frequently to
69 make subsequent repeat queries much faster. The cache size is
70 set to 100 by default for each type (select and update queries).
71 This must be at least 2 as a minimum, any less and a value of 3
72 is used instead. The number represents the number of cached
73 statements to keep around. This environment variable is used
74 mainly for testing purposes.
75 TRACKER_PRAGMAS_FILE
78 Tracker has a fixed set of PRAGMA settings for creating its
79 SQLite connection. With this environment variable pointing to a
80 text file you can override these settings. The file is a \n sep‐
81 arated list of SQLite queries to execute on any newly created
82 SQLite connection in tracker-store.
83 TRACKER_DISABLE_MEEGOTOUCH_LOCALE
86 If Tracker is compiled with meegotouch locale management sup‐
87 port, setting this variable in the environment will disable
88 retrieving the locale from GConf, and the standard locale set‐
89 tings will be used instead.
90 TRACKER_USE_LOG_FILES
93 Don't just log to stdout and stderr, but to log files too which
94 are kept in $HOME/.local/share/tracker/. This came into effect
95 in 0.15.3 and 0.16.0. After this version of Tracker, logging to
96 file (usually useful for debugging) can only be done by declar‐
97 ing this environment variable.
98 TRACKER_USE_CONFIG_FILES
101 Don't use GSettings, instead use a config file similar to how
102 settings were saved in 0.10.x. That is, a file which is much
103 like an .ini file. These are saved to $HOME/.config/tracker/
104
107 tracker-store is highly bound to the D-Bus freedesktop project. A D-Bus
108 session is needed for all Tracker processes to communicate between each
109 other. D-Bus is our acting IPC. See dbus-daemon(1) for more informa‐
110 tion.
