AEM FAQs

Follow this page to get answers to some AEM troubleshooting and configuration issues.

Sites

How do I configure binary-less distribution?

Binary-less distribution is supported for deployments over a shared data store and involves agents that leverage the Vault-based Distribution package exporter (factory PID: org.apache.sling.distribution.serialization.impl.vlt.VaultDistributionPackageBuilderFactory ) package builder.
With binary-less mode enabled, the content packages distributed contain references to binaries rather than the actual binaries.

How do I enable binary-less distribution?

To enable binary-less distribution, deploy with a shared blob store. Check the useBinaryReferences property in the OSGI configuration with the factory PID ( org.apache.sling.distribution.serialization.impl.vlt.VaultDistributionPackageBuilderFactory ) that your agent is using.

How can I customize the error messages while navigating page hierarchy in AEM sites console?

Check the Network panel (of Chrome browser) where a personal setup (JS has not been minified).
View the Initiator column to determine what the initiator of a request was. It provides the files and the line numbers from where the AJAX calls are made. Later, you can trace the error handling function and change the error message as per your requirement.

How to enable permissions while creating Language Copy for Content-Authors in AEM?

To create language copy feature, content-authors need permissions at /content/projects location.
If one requires the authors to manage projects as well, then the workaround is to add the author to project-administrators group.

How to change the format while creating Language Copy for a project?

Create a language root and language copy inside the root, before creating a translation project.
For example, Create a language root at /content/geometrixx with name as fr_LU (and title as French (Luxembourg)). Subsequently, create language copy of page from the references panel and navigate to Create structure only option in Create & Translate . Finally, create a translation project and then add the language copy to the translation job.

You need to change the JS processor default configs property of the Adobe Granite HTML Library Manager to min:gcc . To import the Design Package successfully, it is recommended to include pre-minified 3rd party libraries in our Client-Side Libraries.

Assets

Why the Assets workflow repeats itself while uploading MP4 files (for example, using drag-and-drop method)?

If the user, uploading the movie files does not have delete permissions under asset node, the delete chunk nodes fail and the upload restarts.

What is the maximum number of digital assets that can be operated with AEM 6.4 at a time?

Adobe Experience Manager (AEM) 6.4 currently lets you upload up to 2 GB of assets at a time.
For additional information on maximum number of assets that can be operated with AEM 6.4, see Assets sizing guide .

What are the default settings for OOTB configurations while creating Language Copy?

When creating language copies through classic UI, Assets are not moved under the new language hierarchy but used from the language master.
Whereas, when you create a language copy through Touch UI ( References -> Update Language Copy ), a new DAM folder is created under the new language and assets are referenced from there.
This is default setting for OOTB configurations. You can set Translate Page Assets = Do not translate in Translation configurations. For AEM 6.4, Tools > Cloud Services > Translation Cloud services .

How to disable an AEM component causing exponential growth for the AEM SegmentStore (AEM 6.3.1.1)?

You can disable the OSGi Component Disabler. To use this service, see OSGi Component Disabler .

What is the difference between CoralUI 2 and CoralUI 3-based components?

A new set of Sling components of Granite UI Foundation is created for Coral3 and is located under /libs/granite/ui/components/coral/foundation. There is one set for CoralUI 2-based components and one set for CoralUI 3-based components. The new set will not be just a copy-paste of the old set, rather it will be cleaned up (for example streamlining, removing deprecated feature). So it is recommended that a page only use either CoralUI 3-based or CoralUI 2-based set.
To learn more in detail, refer to Migration Guide to CoralUI 3-based .
