Adobe AD0-E134 Exam With Confidence Using Practice Dumps

Creating a heap dump and a thread dump are two steps that should be taken after confirming the problem is related to a memory issue. A heap dump is a snapshot of the memory usage of the Java Virtual Machine (JVM) at a given point in time. A heap dump can be used to identify memory leaks, memory consumption patterns, and objects that occupy large amounts of memory. A thread dump is a snapshot of the state of all threads that are part of the JVM process. A thread dump can be used to identify deadlocks, blocked threads, and CPU-intensive threads. References:

To create Sling Models that can export data in a human-readable yaml format, the following steps are required:

Create Sling models to export as yaml. Sling models are Java classes that can be used to represent resources in AEM. Sling models can use annotations to define how they can be adapted from a resource and how they can export data in different formats. To export data in yaml format, the Sling model class needs to use the @Model annotation with the resourceType parameter set to the resource type of the resource that the model represents. The Sling model class also needs to implement the org.apache.sling.models.annotations.Exporter annotation with the name parameter set to “jackson” and the extensions parameter set to “yaml”. The Sling model class also needs to use the @JsonProperty annotation on the fields or methods that need to be exported in yaml format.

Configure mime type in Apache Sling MIME Type Service. The Apache Sling MIME Type Service is an OSGi service that maps file extensions to MIME types and vice versa. To enable the yaml format for Sling models, the MIME Type Service needs to be configured with a new entry for the yaml extension and its corresponding MIME type, which is “application/x-yaml”. This can be done by creating an OSGi configuration for the org.apache.sling.commons.mime.internal.MimeTypeServiceImpl service and adding the entry “yaml=application/x-yaml” to the mime.types property.

When performing an in-place upgrade to the latest version of AEM, there are several potential disadvantages to consider:

Long and Arduous Process:

The complexity and duration of the upgrade process can be significant, especially if there is a considerable version difference between the old and new AEM instances. This is because the upgrade process must account for all the changes and improvements made over multiple versions, including content structures, APIs, and underlying technologies.

Complex Developer Setup and Automation:

Upgrading AEM involves setting up and configuring the environment, updating custom code, and ensuring that all integrations work seamlessly. Automating these tasks can be complex and time-consuming, requiring significant developer effort to script and validate the upgrade process.

These disadvantages highlight the potential challenges and resource investments needed for an in-place upgrade.
