This export process saves all Matrix data, both configu-
ration and production data, to the file. Graco recom-
mends this export process be done, at minimum, any
time the system configuration is changed—a meter’s
configuration is changed, a new meter is added, a new
user is added, etc. If the PC has a hard disk failure or
becomes otherwise unusable, the Matrix application
software can be reloaded and the last saved database
file can be imported to recover from the event—see
Importing a Matrix Database File for details. Graco
recommends the backup database file be stored some-
where other than the Matrix PC’s hard disk—such as on
a network drive, on a CD or DVD, or on an external
drive.
This database export process can be done at any time
without interfering with normal operation of the Matrix
system.
Importing a Matrix Database File
Matrix can import database files created by the export
routine described in Exporting the Matrix Database in
this manual.
The primary purpose of importing a Matrix database file
is to allow recovery from a catastrophic PC hardware or
software event, such as a hard disk failure or reinstalla-
tion of Windows. It is a process that should not be taken
lightly. If the import process is not done correctly, Matrix
may malfunction or could fail completely and require a
manual reconfiguration of the entire system, including
reprogramming of all meters and tank level monitors.
Read and understand the database import process and
its ramifications before importing a database file.
When a database file is imported, the contents of the file
completely replace all elements of data that the Matrix
system has. This includes system configuration and pro-
duction data.
Configuration data. Configuration data is all the sys-
tem setup parameters, such as system, user, meter,
tank level monitor, and e-mail event parameters.
Production data. Production data is all data that Matrix
generates as part of normal system operation, such as
meter dispense history, tank level reporting history, etc.
Since the database file’s contents replace the corre-
sponding settings and data in Matrix, any configuration
changes made and production data generated since the
file’s creation will be lost.
If there are differences between, for example, meter
parameters in the database file and the actual pro-
grammed parameters in the meter itself, the resulting
system behavior is unpredictable. The meters will have
to be reprogrammed to ensure the PC and meters are
match exactly. This also applies to tank level monitors.
Therefore, export the database to a backup file when-
ever the system configuration is changed.
The database file being imported must have been cre-
ated by the Matrix system you are using. If you’re
upgrading from an older version of Matrix PC software
to this version, you must contact your authorized Graco
distributor for assistance.
The contents of the database file being imported will
completely replace all elements of data that the existing
system has. This includes system configuration and pro-
duction data.
The import process is not reversible, meaning that you
can’t “undo” the import. However, there are precautions
that you can take to recover an previous database fol-
lowing an import (see step 3 of the import instructions
below).
Follow the instructions carefully when import-
ing a database file. If this process is not done cor-
rectly, Matrix may malfunction or could fail
completely and require a manual reconfiguration of
the entire system, including reprogramming of all
meters and tank level monitors.
