System administrators can modify system-wide settings by selecting Management tab, as in the following example:and then selecting the
The Readonly section of the System Settings page allows you to enable or disable read-only mode, which allows administrators to perform maintenance or diagnose performance problems while a V‑Spark installation is still running.
While in read-only mode, V‑Spark cannot process new data, and user, folder, company, organization, and system settings cannot be changed. V‑Spark may still be used to examine existing data that has already been processed.
To enable or disable read-only mode:
- Click Management tab. and select the
- Select the Put V‑Spark in readonly mode checkbox.
A text box containing the default announcement displays. This message may be edited, and it appears when any user logs in while read-only mode is enabled.
- Click Save to save the message and enable read-only mode.
- To disable read-only mode, deselect the Put V‑Spark in readonly mode checkbox and click Save.
Safe mode and low storage
If V‑Spark does not have sufficient storage, it will automatically enter safe mode, which is similar to read-only mode. Any file processing when safe mode activates will complete, but no new data can be added to the system.
All users will see a notification banner indicating that the system is in safe mode. Users can still use V‑Spark to examine data that has already been processed, and can reprocess applications against that existing data.
V‑Spark may not be taken out of safe mode until it has sufficient storage.
The Announcements section of the System Settings page enables system administrators to add, change, and remove system-wide announcements. New announcements are displayed to all users the first time that they log in after an announcement is created.
Use the following procedure to create an announcement:
Click Add announcement. The following textbox displays:
Enter the text of your announcement in the textbox and click Save.
When a user logs in, all announcements created since that user's last login will be identified as New. Announcements are only identified as new the first time that a user logs in after the announcement was created. Afterward, announcements are displayed without the New identifier until they are deleted. Announcements can also be hidden by users during their login sessions.
To modify an existing announcement, edit the text for that announcement and click Save. Updated announcements are not displayed as New when users log in. To cause an existing announcement to be identified as new, delete the old announcement and create a new one with the updated text.
To delete an announcement, click Delete. The Undo icon will restore the deleted announcement until you click Save.
