SYNOPSIS

10       tracker-store [OPTION...]
11
12

DESCRIPTION

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
18       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.

OPTIONS

25       -?, --help
26              A brief help message including some examples.
27
28       -V, --version
29              Returns the version of this binary.
30
31       -v, --verbosity={0|1|2|3}
32              Sets  the  logging  level,  0=errors,   1=minimal,   2=detailed,
33              3=debug.
34
35       -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
40       -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.

ENVIRONMENT

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
52
53       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
58
59       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
66
67       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
76
77       TRACKER_USE_LOG_FILES
78              Don't  just log to stdout and stderr, but to log files too which
79              are kept in $HOME/.local/share/tracker/. This came  into  effect
80              in  0.15.3 and 0.16.0. After this version of Tracker, logging to
81              file (usually useful for debugging) can only be done by  declar‐
82              ing this environment variable.
83
84
85       TRACKER_USE_CONFIG_FILES
86              Don't  use  GSettings,  instead use a config file similar to how
87              settings were saved in 0.10.x. That is, a  file  which  is  much
88              like an .ini file.  These are saved to $HOME/.config/tracker/

NOTES

92       tracker-store is highly bound to the D-Bus freedesktop project. A D-Bus
93       session is needed for all Tracker processes to communicate between each
94       other.   D-Bus  is our acting IPC. See dbus-daemon(1) for more informa‐
95       tion.
