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 and serves as a daemon  waiting
20       for such requests from application miners like tracker-miner-fs.
21
22       For help on how to configure this daemon, see the man page for tracker-
23       store.cfg.

OPTIONS

27       -?, --help
28              A brief help message including some examples.
29
30       -V, --version
31              Returns the version of this binary.
32
33       -v, --verbosity={0|1|2|3}
34              Sets  the  logging  level,  0=errors,   1=minimal,   2=detailed,
35              3=debug.
36
37       -r, --force-reindex
38              This  forces  tracker-store  to remove databases and to recreate
39              fresh databases ready for data insertion from  the  miners.  For
40              more information about the miners, see tracker-miner-fs.
41
42       -m, --low-memory
43              This changes the behavior of the database manager and some other
44              parts of tracker-store to be optimized for lower memory  systems
45              by  lowering  database connection cache sizes and page sizes for
46              example. This may slow down indexing performance.
47
48       -n, --readonly-mode
49              This starts tracker-store in a mode which  disables  writing  to
50              the  database. Only SPARQL read requests can be serviced if this
51              option is used.

ENVIRONMENT

55       TRACKER_DB_SQL_DIR
56              This is the directory which tracker uses to load the .sql  files
57              from.   These are needed on each invocation of tracker-store. If
58              unset it will default to the correct place. This is used  mainly
59              for testing purposes.
60
61
62       TRACKER_DB_ONTOLOGIES_DIR
63              This  is  the directory which tracker uses to load the .ontology
64              files from. If unset it will default to the correct place.  This
65              is used mainly for testing purposes.

NOTES

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