   i am using jdk1.8.0_211 and i have ran the jar file ( java -jar aem-author-4502.jar )
  

This is my terminal screen-shot :

I did not get error in terminal. i tried fix the issue but not getting proper solution

Please anyone help to solve this issue. i am beginner for AEM.

Answer 1

I have run into similar issue before, and there could be multiple reasons why you are having this issue.

1. Most Probable: It looks like the files in your segment store/ datastore got deleted and this is causing the issue. Possible Solution: Try to find if you have your datastore files in your bin and recover/restore them. This is how they look:

If you cannot find these files in your bin and they have been permanently deleted, you would need to restore your instance i.e. You would need to create a fresh instance

If your repo gets too big try offline compaction ( It is advised to do offline compation every 2 weeks by Adobe)

Revision Cleanup Official Documentation : here

Storage/Segment/Data store maintenance : here

2. Your JVM/JRE or Maven has been unbinded.

Solution: Java:

• To check the Java version on Linux Ubuntu/Debian/CentOS:
• Open a terminal window.
• Run the following command: java -version

3. The output should display the version of the Java package installed on your system.

In the example below, OpenJDK version 11 is installed.

Maven:

• Enter mvn --version in terminal.

If you have both of these commands working properly, that means you would need to check for the deleted files.

Before creating a new instance , make sure to clear your OS/Application cache which is generated in Libraries. ( I'm not sure where cache is stored on Linux.)

Datastore issues are not fixable as the blobs/files created by AEM are randomly generated for different data. And we cannot recreate that. I am afraid you might need to create a fresh instance.
