Delay in Refreshing Notification Counts

[Printer Icon] Print this article

Issue Description: The notification count in My Blackboard > Global Nav seems to take 10 minutes to reflect any changes in notification counts, such as Students dismissing notifications or new notifications being added based on new Assignments or Announcements in Courses. The change in the notification count is expected to be almost instantaneous. This is affecting the "secondary" application server where Amq broker is not residing on.

Steps to Replicate:

  1. Login to Blackboard Learn on a secondary application server
  2. Enter a test Course
  3. Click Create Announcement
  4. Enter a subject and message. Enter date restrictions. Submit
  5. Repeat steps 3-4 to create a second Announcement
  6. Wait several minutes for the notification of the new Announcement to be distributed
  7. Log in as a Student in the Course
  8. Observe that the red notification count in the upper right corner is 2
  9. Select Updates from the My Blackboard tool
  10. Dismiss one of the Announcements
  11. Go to the MyBB tab
Observed Behavior:
 The red notification count continues to display 2. If you stay idle on the page after approximately 10 minutes the notification number will go away

Expected Behavior:
 The red notification count goes away as soon as the User exits the My Blackboard tool

Target Release: Future Reference
Patch Available: No
