overview
This chapter explains the safety measures that should be taken before putting the surveillance system into operation.
The operation of a monitoring system requires safe operation through continuous operation. Even if sufficient development and testing is performed, there is a possibility that an unexpected event may cause a stop or failure during operation. By taking the safety measures described in this chapter, you can automatically restart the application when it abnormally terminates, and save various log files necessary for investigation when a problem occurs.
|
Setting safety measures is very important.By configuring the various settings described in this chapter, various log files necessary for investigating when a problem occurs will be automatically generated. Since this information will be necessary when contacting us for technical support when a problem occurs, we strongly recommend configuring these settings. |
Safety measures for continuous operation
Below we explain the safety measures that must be implemented to ensure continuous operation.
Please refer to each link for details on specific setting procedures, etc.

Get and apply the latest patch program for FA-Server |
Be sure to apply the latest patch program. The latest patch program may have resolved some bugs. Patch programs can be obtained from our website.
Furthermore, if the client is a PC different from FA-Server, please make sure that the same revision is applied to all PCs.

Optimizing the database |
If you are outputting to a database via ODBC from an action, etc., please make optimal settings on the database side to prevent the database from becoming overloaded due to long-term continuous operation.
In particular, consider tuning backup processes and transaction logs.
|
||
Notes on antivirus software |
If you install antivirus software, please configure it so that the IP addresses and port numbers used by FA-Server and FA-Client for communication are not blocked.

Set up safety measures for continuous operation |
By checking "Continuous operation safety measures" on the FA-Server application settings screen, you can set FA-Server to automatically restart if an abnormality occurs. We recommend this setting as it can reduce the time that the system is unmonitored if it abnormally terminates. |
||
Set output log save settings |
Please configure the output log settings in the Output View settings screen of FA-Server. This log can be useful for troubleshooting.
|
||
Configure system log storage settings |
Please configure your FA-Server application settings to save system logs. These logs can be useful for troubleshooting.
|
||
Set FA-Server stop operation to be password protected |
You can set it so that you are required to enter a password when stopping FA-Server. Please set this as necessary.

Disable Error Reporting |
If the "Error Reporting" function of Windows is enabled, a confirmation message will be displayed asking whether or not to send a problem report to Microsoft when an application terminates abnormally. If you enable automatic application restart, you must disable this function because the display of this confirmation message will prevent the application from automatically restarting.
|
||
Crash dump output settings
|
The standard functionality of Windows is to automatically generate a debug information file (dump file) called a "crash dump" when a running application terminates abnormally. If our application terminates abnormally, sending us the crash dump may help us to resolve the problem more quickly. We strongly recommend that you leave this setting enabled unless you have a special reason not to do so.
|
||
Install the latest update for Windows |
Potential issues with Windows may affect continuous operation. Please update Windows on the actual PCs you will be deploying to the site.
|
||
Disable automatic updates for Windows Update |
If WindowsUpdate is set to automatic updates, the OS may restart automatically. Please consider the settings according to your operating environment.
|
||
Consider disabling WindowsSearch |
If the WindowsSearch function is enabled, the continuous operation of the monitoring system may be affected due to increased memory consumption caused by updating the search index by the OS and the enlargement of index files. Consider disabling this function depending on your operating environment.
|
||
The Time sync of the PC running FA-Server |
The time on your PC will gradually become inaccurate. If the time on your PC is changed significantly while your FA-Server is running, this may affect the timestamps in the logging files. Consider whether or not to NTP your PC, and if so, which PC (NTP server) you want to sync the time with, and then configure it appropriately.
|
||
Firewall settings |
If you enable a firewall, make sure to configure it so that the IP addresses and port numbers used by FA-Server and FA-Client for communication are not blocked.
