AEM6.3 how to find the Binaries location on file system

Statement : Identify the Binary Location on file system

Environment : AEM 6.3

Solution :

1.       Go to this path  http://localhost:4502/crx/de/index.jsp#/content/dam/projects/we-retail/cover/jcr%3Acontent/metadata

2.       And Navigate to this path in crxde search : /content/dam/projects/we-retail/cover/jcr:content/metadata

3.     Check the value of dam:sha1 and that shows the binary location on file system Dam:sha1 =a81372af7d4d9ab856cad6e293ea48e653f0e278

4.     Whereas first letter a813 indicates datastore location  on the file system where - \crx-quickstart\repository\datastore\0a\81\13  and you can observe the asset located under with file type .file : 0a81135558804df12feb78bd994c0f4416aad830

Steps to Tune the Sling Job Queues

Statement: Tuning the Sling Job Queues

Environment : AEM 6.3

Issues Faced :

• A large amount of content was activated by the content authors resulting unresponsive publishers.

Solution :

1. Go to this path  : http://localhost:4502/system/console/configMgr
   
2. Search for Apache sling job queue configuration and open it for edit and default value for parallel jobs is 15
   
   
   
   
   
3. Change the parallel Jobs value to 4 if CPU core is 8, Key in the value - Maximum Parallel Jobs = 4.0 
   
4. Save the changes.it will create two file one for old and one for new value
   
   
   
   
   

Reason to changes the parallel Job value in Sling Job queue configuration

1. The bulk upload of large assets may be very resource intensive. 
2. By default the number of concurrent threads per job queue is equal to the number of CPU cores, which may cause an overall performance impact and high java heap consumption.
3. It is recommended to not exceed 50% of the cores
4. For example for 8 CPU core , Maximum parallel jobs value would be 4(8 core = 4 Jobs in parallel)
