System Overview

Figure: Example of a system overview

The intention of this panel is to give the user a general overview about the condition of the Disaster Recovery System. It shows:

• The PSS and SSS error status with alert lines (errors are shown that occur during a synchronization process) in the middle area of the panel.

• The connection between the systems.

• The connection to the database.

• The active/passive status of the systems.

Furthermore, via this panel the user can activate a manual switching between the systems and a general synchronization of the online data and the alarm status (configuration synchronization) can be started.

In the tables in the middle of the system overview panel the alerts of the respective server system are displayed.

Note

If the maximal parsing time (maxParseTime) is exceeded by the Event manager when constructing the queries for the synchronization of the online values, an alert is displayed in the table. If this error occurs, online values can not be synchronized correctly between the SSS and PSS.

Click left on the area of a server system (see figure above) of the primary or the secondary server system to open the panel for the System overview in redundant systems. In this area also the output of the current and maximum error state is displayed.

If one of the bots systems is in split mode, this is shown in the system overview panel and the file synchronization is not possible during this time.

Note

The split mode can only be activated on the primary server system. On the secondary server system this option is disabled.

Visualization of a crash of the active server in the system overview panel

If all 4 servers of the DRS are running, the active servers are displayed with the color green in the background and the passive servers with the color cyan.

If the active server of the PSS/SSS crashes, its backgrounds color changes to red and the background color of the passive server changes to green, because this became active.

If the passive server of the PSS/SSS crashes, its backgrounds color changes to red and the background color of the active server remains green. When the passive server is restarted again, its background changes to cyan again.

Buttons

• “Send all Values“
  
  Sends all online data and the alarm status to the other system. This virtually corresponds to a general synchronization of the systems.

• “Set Active“
  
  Sets the corresponding system to active and automatically sets the other to passive. That means that a manual switching is carried out.

• "DRS driver connection"

Allows setting a driver connection that is handled by the DRS (see also Configuration -> Managers) to active/inactive from DRS point of view.

With this panel the driver connections of all drivers handled by the DRS can be activated or deactivated from DRS point of view. Which status the connections at the PSS and SSS actually get assigned depends on the used driver mode.

For example:

Setting a connection of the IEC driver to active. The driver is running:

• in mode 0 or 2 -> connection becomes active at the PSS and SSS

• in mode 1 -> connection becomes active on the active system and inactive on the passive system

• "Configuration synchronization"
  
  Triggers a manual configuration synchronization between the PSS and SSS.

• "User/Password"
  
  Click on this button to open the panel for user data synchronization between the PSS and the SSS.

• "Historical Synchronisation"
  
  Opens the panel via which the synchronization of the historical data can be activated (see Database Synchronization).

• “Close”
  
  Closes the system overview.

Synchronization of user data and passwords

Click on the “User/Password” button in order to open the panel for synchronizing user data and passwords between the PSS and the SSS.

In the table, all users of the corresponding system (PSS and SSS) are automatically listed together with their passwords.

The following commands can be sent via the buttons here:

• Password PSS => SSS
  
  Synchronises the password of the chosen user from the PSS in the direction of the SSS.

• Password SSS => PSS
  
  Synchronises the password of the chosen user from the SSS in the direction of the PSS.

• Synchronisation PSS => SSS
  
  Carries out a complete synchronization of the user data from the PSS in the direction of the SSS.

• Refresh
  
  Updates the table.

• Close
  
  Closes the panel.
