A company is anticipating a large migration of web assets into their AEM instance. Bulk upload of large assists is typically a very resources intensive process.
The DevOps Engineer needs to avoid any potential performance impact and high Java heap consumption.
Which change should the DevOps Engineer make to the Apache Sling Job Queue Configuration?
A DevOps Engineer must configure a production deployment pipeline. The AEM environment consists of one author instance, two publish instances, and two dispatcher instances. A load balancer and CDN are also leveraged.
In combination with load balancing which step is required to make sure that the site is available during deployment?
An html page is published and is accessible through the dispatcher. A client is trying to access the updated page but is not getting the updated content.
* A rule /type ''allow'' /glob ''*.html'' is present in the dispatcher /cache /rules configuration
* The HTTP header ''Cache-Control: max-age=3600'' is set for all requests with the html extension
* The /invalidate section is not set in the dispatcher configuration
* A flush agent is configured on the publish instance
* A CDN is serving all static content including html files and was flushed manually
Why does the content fail to update on the client side?
A DevOps Engineer notices that the disk usage for an AEM author instance is constantly going up.
Upon further investigation, it is revealed:
- Online Compaction is unable to complete revision cleanup task during the daily maintenance window
- Segment Store Size has gone up from 8 GB to 13 GB
- The following message is logged in the error.log file
Canceling RevisionGC. The task was either stopped by the user or the Maintenance Window reached its end - Lucene Binaries Cleanup task completed successfully during the daily maintenance window
What additional step can be performed during the weekly maintenance window to reduce the overall disk usage?
