Allows controlling various Domain configurations. To open this item, right-click the E3 Admin icon on Windows Notification Area, select the Domain - Options option, and click the Properties tab. The window on the next figure is then displayed.
Properties tab
The Alarms group contains the Save alarm summary option, which allows saving the alarm summary and therefore avoiding duplicated alarm notifications when opening or closing a Domain. By default this option is disabled. To enable it, select the Enabled option on the Enable item and specify a time interval, in minutes, in the Time interval option. The default time interval of this option is 1 (one) minute. These saved alarms are loaded whenever a Domain is opened and saved in the interval specified in the Time interval option or whenever a Domain is closed. Saving alarms is not performed when stopping or executing a Domain, because the alarm summary is kept in memory.
NOTES |
•In case of servers in Hot-Standby mode, both servers save the alarms. •Only alarms visible in the summary are saved. •When disabling this option, the previously saved alarms are deleted, to prevent outdated information when enabling this option again. |
The General group contains the Domain name option, which allows configuring a friendly name for a Domain. If this option is left blank, the Domain name then corresponds to the name of the Domain file without its .dom extension. This name is available via script at run time by using the Domain property of the Domain Information object, such as "Application.GetObject('[?Server].Domain').Domain".
The IOServer Process Pool group contains the options described on the next table.
