56.7.4 Database
56.7.4.1 Overview
On the Database tab (see figure 56.12), the properties of
the logging database can be defined.
56.7.4.2 Recent events
Use the Recent events block to define the number of
recent events that is displayed in the Logging Viewer (see
section 57.6.2.3).
56.7.4.3 Database file
Use the controls in the Database file block to define:
• The location of the logging database. This can be
entered in the upper text box.
• The critical size of the logging database. When the
critical size is reached, the Logging Server displays the
following message (see section 56.5.2): The Logging
Server database has reached its critical size. Please decrease
the logging expiration periods.
It is possible to make a back-up of the logging database
(even if the Logging Server is running). When a back-up
is made of a running Logging Server, it is advised to
wait for a moment at which a low number of events is
expected (i.e. when there are almost no running calls).
Events that occur while the back-up is made will not be
copied to the logging database. However, events that
occurred during the back-up process can be viewed with
the standard Windows Event Viewer (Start > Settings >
Control Panel > Administrative Tools > Event Viewer).
56.7.4.4 Flush events
Use the controls in the Flush events block to flush events
from the logging database. Proceed as follows:
1 If the fault events must be flushed from the logging
database, put a check mark in the Fault events check
box.
2 If the general events must be flushed from the
logging database, put a check mark in the General
events check box.
3 If the call events must be flushed from the logging
database, put a check mark in the Call events check
box.
4 Click the Flush now button to flush the selected types
of events from the logging database.
• If the Move expired events to overflow file field of the
selected type of events on the Logging Expiration
tab (see section 56.7.3) contains a check mark, the
selected type of events are flushed to an overflow
file.
• If the Move expired events to overflow file field of the
selected type of events on the Logging Expiration
tab (see section 56.7.3) does not contain a check
mark, the selected type of events are deleted from
the database.

Note
For experts only: the logging database is a
Microsoft® Access file, which also can be
opened with Microsoft® Access. If for any
reason the database becomes corrupted and
the Logging Server is not able to access the
database, the database can be repaired with
Microsoft® Access.
Close the Logging Server application.
Open the database with Microsoft® Access.
Select: Tools > Database utilities > Compact
and Repair database.
Note
When the database is flushed and the Logging
Server is started again, the database is filled
with the events that are retrieved from the
enabled network controllers. Each enabled
network controller keeps an internal list of up to
200 events of each type. Use the File Transfer
application to clear the internal list (see section
36.6).
