Replication agents & DAM

Replication agents:

-----------------------------

They help to publish the content. Replication agents are mapped to publication. So when we need more than one publish environment, we need replication agents for each one.

Access replication agents through Tools>Replication

Publish flow:

Once site is developed it should be activated by going website> activate

It send alert to replication agent, the request will be put in a queue will be formed for it.

We can restrict continuous attempts of publish through Agents>Setting>Extended> connect time out.

Settings

On modification - helps to publish a page immediately after modification

Activating (publishing) more pages together in AEM/Adobe cq

Access replication tree using below url.

http://localhost:4505/etc/replication/treeactivation.html

Now activate more pages by selecting pages or entire directory.

How to publish a Component immediate after creation or modification?

Push component to publish through Crxde lite by selecting component, then go to replication tab, click on replicate. This will send component immediately to publish.

We have manual way of publishing through build bundle-> install to publish environment. Easier solution to publish content is,we can use direct replicate for the package. For this ensure you configured replication agents.

DAM:

----------

Thumbnails are created automatically in DAM because it is defined default by Adobe in workflow:

http://localhost:4505/cf#/etc/workflow/models/dam/update_asset.html : step> Thumbnail creation

Use sidekick > DAM workflow to create dam related workflows.

All items we uploaded can be seen in CRXDE through http://localhost:4505/crx/de/index.jsp#/content/dam

References section gives the list of all references from pages for an image. Double click on image and see right top (renditions,versions,references)

Securities:

Change admin or author passwords:

------------------

1)

http://localhost:4505/crx/explorer/index.jsp > 'Content explorer' opens below url

http://localhost:4505/crx/explorer/browser/index.jsp

now

Security > change password.

2)

http://localhost:4505/crx/explorer/index.jsp > 'User Administration' opens below url

http://localhost:4505/crx/explorer/ui/usereditor.jsp?ck=1402297401235&Path=/home/users

Select a>admin>change password

Create or delete users canbe done through http://localhost:4505/useradmin.

All users’ preferences can be done through above url.

OSGi component Vs CQ component:

OSGI-Backend part- business component;

CQ-front end part

OSGI bundle can have many no of osgi components and each component can have many services.

AEM/ Adobe CQ: Version controlling

CQ uses svn by default.

Filevault ( VLT)is used when we need crx file system to be available in local system(like accessing code using eclipse).

Create back up of crx code using file vault

To set up the filevault, we need to unzip the filevault file and configure its bin path to system path variable.

Export project from CQ to local machine

c:\CQ5_training\backup>vlt --credentials admin:admin export -v http://localhost:4505/crx /apps/training .

Above command creates a jcr_root folder in backup folder and put all files from crx

Import Project from Local file system to CQ

c:\CQ5_training\backup>vlt --credentials admin:admin import -v http://localhost:4505/crx . /apps/training

Once user credential is entered, it is not required again bcz, the user credential is saved in user directory> vault folder as an xml file.

Checkout just directory structure, not entire project

backup>vlt -co http://localhost:4505/crx/-/jcr:root/apps/training .

Identify locally modified files, execute below command.

jcr_root>vlt -st

Identify difference in local and crx files, execute below command.

jcr_root>vlt -diff complex/components/test.jsp

jcr_root>vlt diff will give all changed fields comparison in jcr_rot checked out directory

commit changes to code repository:

All files:

jcr_root>vlt - ci

Single file commit:

jcr_root>vlt - ci filename

Note: ci,st,diffcommaond only works withchecked out code , not exported code.

Workflow, performance monitoring, logging in AEM

Workflow:

Used to automate process involved in page creation to publish.

http://localhost:4505/libs/cq/workflow/content/console.html

Launcher workflow enables to automate the workflow in AEM.

·         Instance tab shows running workflows which can be suspended or cancelled.

·         Models list all work flows created.

·         Archive : shows completed workflows

·         Failures: Shows all the failed workflows.

Error /Failure in Workflow custom process "Process implementation not found: "

The reason may be you are creating bundle using CRXDELite and below codes are commented.

#Export-Package: *

#Import-Package: *

Solution:So you have to uncomment to get the workflow success.

Performance:

Logging

Request.log files will have all requests logged. Monitoring this log is the best way to track performance issues. We can also use some profilers to tackle the performance issues.

Tool helps to track last few requestsAuthor\crx-quickstart\opt\helpers > rlog.jar

To access logs,

From command prompt reach to the location of rlog.jar then > execute java -jar rlog.jar -n 10  ../../logs/request.log will give all slowest responses.

Readable: http://dev.day.com/docs/en/cq/current/deploying/performance.html

Timing chart URL will also help to find the performance timing of any page loading.

AEM/CQ Common issues

Rectify Content Assist issue in AEM/ Adobe CQ(5.6)

-------------------------------------------------

We need CRXDE to have installedfuture pack to get content assist for JSP pages

Download link: http://blogs.adobe.com/livecycle/2012/06/developers-faq-on-cq5-5.html

·         Missing crx de libs(missing-crxde-libs.zip) to be install through package manager.

·         Now rename or delete user>.crxde folder, restart the crxde so that content assist works fine.
