CRX/DE console doesn't show node-tree in the AEM 6.2 for the run mode - Author, CRX3 and samplecontent

Issue: CRX/DE light console doesn't show nodetree

- Run mode for Author instance as follows:

  • sling.run.mode.install.options=author|crx3|samplecontent

- Post the installation of Author instance in crx/de console shows nothing in the tree-node, refer the below screenshot.
http://localhost:4502/crx/de/index.jsp











Solution:
- Go to the http://localhost:4502/system/console/configMgr
- Search for Apache Sling DavEx Servlet
- Root path shows only /Server as shown in the below screenshot.










- Change root path from /server to /crx/server and save it.



- Go back to the /crx/de console , You will be able to see the node-tree as shown below.

How to turn any workflow model to “transient" Model

Issue:
How to turn any workflow model to Transient model:

 Step1: Go to the below URL
http://localhost:4502/miscadmin#/etc/workflow/models/dam

Step2: Open any workflow model for eaxmaple - DAM Update asset.

Step3: Click on the page tab--> properties of Sidekick.

Step4: Check the enable Transient workflow under Basic tab.

Step5: Click on Ok. That's It!. as shown below


- Do not enable this option if user interested to see the run time data.

Advantages of Transient workflow:

  • Run-time Data related to any intermediate workflow steps will not be persisted into the JCR.
  • Of course the output of renditions/workflows will be persisted.
  • Lesser repository growth. 
  • Lesser/no more Workflow Purge
  • lesser tar file campact
  • increase in performance.

Note: Applicable for AEM 6.1/6.2/6.3/6.4

      # The docroot must be equal to the document root of the webserver. The
      /docroot "/data/aem/dispatcher/cache"
      # Sets the level upto which files named ".stat" will be created in the
      #/statfileslevel "0"
      # Flag indicating whether to cache responses to requests that contain
      # authorization information.
      #/allowAuthorized "1"
      # Flag indicating whether the dispatcher should serve stale content if
      # no remote server is available.
      /serveStaleOnError "0"
      # The rules section defines what responses should be cached based on
      /rules
        {
        /0000

Performance tuning
# this configuration file extends the basic httpd.conf
# it includes a number of options that are used to improve performance
# turn off Etags completely, since they will differ across the cluster
FileETag None
# instead we use Expires and Cache-Control headers
ExpiresActive On
ExpiresByType text/css "access plus 1 year"
ExpiresByType text/javascript "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType application/x-shockwave-flash "access plus 1 year"
# force set Vary header so it works with proxies and IE properly
Header set Vary "Accept-Encoding"
        # enable compression for text file types: html, css, js, XML
        AddOutputFilterByType DEFLATE text/plain
        AddOutputFilterByType DEFLATE text/html
