Integrating AEM into application servers and web servers

A client’s site fails to display the most recent page content for some site visitors. The client operates two data centers, each configured with a Dispatcher connected to two Publish machines. The load issue occurs only intermittently for visitors from one data center.

Which action should the Architect take to resolve the issue?

  • A Review the log files on the Author instances to determine if there are any template errors
  • B Check the Publish instance(s) attached to the Dispatcher associated to the impacted data center
  • C Disable caching on all impacted data centers Dispatchers to force the Publish machines to serve the page content
  • D Check the SSL certificate on the impacted data center's load balancer.
Explanation

AEM Dispatcher serves cached content and retrieves a newly rendered page from its attached Publish instance when the cached content is invalid. Because the stale-content behavior is isolated to one data center, the relevant fault domain is that data center’s Dispatcher and its connected Publish instances; an unavailable or out-of-date Publish instance can intermittently return older content. Adobe documents that Dispatcher uses Publish instances for rendering and that cache invalidation is required when content is activated.
