Managing High Available Applications : Q & A
Hi was going through the Managing High Available Applications Q & A.
Which component in a high availability architecture is useful to recover a single user session data in crash recovery? (Choose One)
Application Server Cache
For this question , as per the Q& A correct answer is mention as Shared Storage.
But the question talks about single user session data in crash recovery. Single User session data recovery is required only when the browser crash. When the server Crashes, multiple user session will be involved. As per my understanding, For browser crash, application server cache is the better approach . Kindly suggest
Please review the lesson content before posting. Single user session crash recovery applies to both browser and server crash. In case of server crash, it uses the shared storage layer and in case of browser crash, it uses the user interface metadata stored on a shared file location. In both cases the application server cache is not relied.
