NAME
tracker-store - database indexer and query daemon
SYNOPSIS
tracker-store [
OPTION...]
DESCRIPTION
tracker-store provides both a powerful database daemon which allows
clients to query or update their data using the highly descriptive
SPARQL language.
tracker-store does not do any file crawling or any mining of data
itself, instead other processes do that while
tracker-store serves as
a daemon waiting for such requests from application miners like
tracker-miner-fs.OPTIONS
-?, --help A brief help message including some examples.
-V, --version Returns the version of this binary.
-v, --verbosity={0|1|2|3} Sets the logging level, 0=errors, 1=minimal, 2=detailed,
3=debug.
-r, --force-reindex This forces tracker-store to remove databases and to recreate
fresh databases ready for data insertion from the miners. For
more information about the miners, see
tracker-miner-fs. -n, --readonly-mode This starts
tracker-store in a mode which disables writing to
the database. Only
SPARQL read requests can be serviced if
this option is used.
ENVIRONMENT
TRACKER_DB_ONTOLOGIES_DIR This is the directory which tracker uses to load the .ontology
files from. If unset it will default to the correct place.
This is used mainly for testing purposes.
TRACKER_LANGUAGE_STOP_WORDS_DIR This is the directory which tracker uses to load the stop
words dictionaries from. If unset it will default to the
correct place. This is used mainly for testing purposes.
TRACKER_STORE_MAX_TASK_TIME This is maximum time allowed for a process to finish before
interruption happens. The actual moment of interruption
depends also on the frequency of checks. The value 0 indicates
no interruption. This environment variable is used mainly for
testing purposes.
TRACKER_STORE_SELECT_CACHE_SIZE / TRACKER_STORE_UPDATE_CACHE_SIZE Tracker caches database statements which occur frequently to
make subsequent repeat queries much faster. The cache size is
set to 100 by default for each type (select and update
queries). This must be at least 2 as a minimum, any less and a
value of 3 is used instead. The number represents the number
of cached statements to keep around. This environment
variable is used mainly for testing purposes.
TRACKER_PRAGMAS_FILE Tracker has a fixed set of PRAGMA settings for creating its
SQLite connection. With this environment variable pointing to
a text file you can override these settings. The file is a \n
separated list of SQLite queries to execute on any newly
created SQLite connection in tracker-store.
TRACKER_DISABLE_MEEGOTOUCH_LOCALE If Tracker is compiled with meegotouch locale management
support, setting this variable in the environment will disable
retrieving the locale from GConf, and the standard locale
settings will be used instead.
TRACKER_USE_LOG_FILES Don't just log to stdout and stderr, but to log files too
which are kept in $HOME/.local/share/tracker/. This came into
effect in 0.15.3 and 0.16.0. After this version of Tracker,
logging to file (usually useful for debugging) can only be
done by declaring this environment variable.
TRACKER_USE_CONFIG_FILES Don't use GSettings, instead use a config file similar to how
settings were saved in 0.10.x. That is, a file which is much
like an .ini file. These are saved to $HOME/.config/tracker/
NOTES
tracker-store is highly bound to the D-Bus freedesktop project. A D-
Bus session is needed for all Tracker processes to communicate
between each other. D-Bus is our acting IPC. See
dbus-daemon(1) for
more information.
