Database Size
Shadow Tracker Professional includes a feature that continually monitors the size of your database.
Allowing a database to become too large increases the risk of GPS data records becoming
permanently corrupted. Therefore, when your database reaches 1.5 GB in size, you will begin to
receive promptings urging you to perform a Purge and Compact operation and/or to archive the
database.
If these promptings are ignored and the database is allowed to reach a size of 1.8 GB, the database’s
status will automatically be converted to read-only. If this occurs, no data will be lost, but the
database will be rendered incapable of accepting any more data. To correct this, the database will
need to be reduced in size by performing a Purge/Compact operation. This is done to ensure that
your GPS data records will never be corrupted due to database size.
N
OTE: Before performing any data maintenance, it is recommended that you first make a backup
copy of your database.
Compact Utility
Data in your program is constantly being added, evaluated and rearranged. As a result, your database
can become fragmented and use disk space inefficiently. Compacting the database makes a copy of
the database and then rearranges how the data file is stored on disk. You can perform a compact on
your database at anytime to release disk space, so your program runs more efficiently.
To compact the database:
Close all other Shadow Tracker Professional programs, i.e. Shadow Tracker, Premier Base
Extractor, Wireless Grabber or Data Processor.
1 In the Administrator window, select Database > Compact.
2 In the DB Compact Utility window, click the Start Compact Procedure button.
When the compact operation has completed, you will receive a confirmation message in the
Status window: Compacting operation was successful.
3 Click Exit to close the DB Compact Utility window.
