How to Start and Stop AEM instance locally

There are altogether 3 methods to start and stop AEM instance
1. Double-click the jar file
2. Using Command Prompt
3. Using custom script (start.bat and stop.bat)
Double-click the jar file

Start:-
This is possible with all GUI enabled devices. You can simply double-click the jar file to start AEM. A progress bar will appear on screen to indicate the progress of a start-up.

If you are installing AEM for the first time. It will take time to start as it creates an entire JCR-compliant repository in the background, which may take several minutes [depending on your machine configurations]. After this startup is much quicker as double-clicking on the jar file in the install directory simply starts the instance, it does not re-install it.

Stop:-
To stop the instance from the GUI, simply click the on/off switch on the desktop application window.


How to Start Using Command Prompt
Open command prompt, select the jar file directory and enter the command
for a 32bit VM type:
java -Xmx1024M -jar <Name of jar file>
Or, for a 64bit VM, type:
java -XX:MaxPermSize=256m -Xmx1024M -jar <Name of jar file>
How to Stop Using Command Prompt
Press CTRL-C stop AEM instance.


Using custom script(start.bat and stop.bat)
Use a custom script located in the bin (crx-quickstart\bin) folder, such as start.bat to start AEM. The Start and Stop scripts are for UNIX, Linux, and Macintosh. The start.bat and stop.bat scripts are for Windows.

Note: If you are installing AEM for the first time, you must unpack the jar to access custom scripts in the repository. To unpack the jar use java -jar cq5-author-p4502.jar –unpack command.

The script starts the instance installed in <cq-installation> directory.
For Window’s platform, start the command prompt in <cq-installation>/bin directory and enter the below command to start AEM instance on port number 4506.
SET CQ_PORT=4506 & start.bat
