Replication agents & DAM


Replication agents:
-----------------------------
They help to publish the content. Replication agents are mapped to publication. So when we need more than one publish environment, we need replication agents for each one.
Access replication agents through Tools>Replication


Publish flow:

Once site is developed it should be activated by going website> activate
It send alert to replication agent, the request will be put in a queue will be formed for it.
We can restrict continuous attempts of publish through Agents>Setting>Extended> connect time out.

Activating (publishing) more pages together in AEM/Adobe cq
Access replication tree using below url.
http://localhost:4505/etc/replication/treeactivation.html
Now activate more pages by selecting pages or entire directory.
How to publish a Component immediate after creation or modification?
Push component to publish through Crxde lite by selecting component, then go to replication tab, click on replicate. This will send component immediately to publish.



We have manual way of publishing through build bundle-> install to publish environment. Easier solution to publish content is,we can use direct replicate for the package. For this ensure you configured replication agents.




DAM:

Thumbnails are created automatically in DAM because it is defined default by Adobe in workflow:
