How to display the dynamic popup in a page through GTM?

How to display the dynamic popup in a page through GTM?

This post will explain how to display the dynamic popup in a page through GTM.

The assumption is the required JQuery scripts are included as part of the page.

Define the cookie type variable:

This will help us to display the popup for every new browser session(this step is not required if the popup should displayed every time visiting the page)
  • Click on Variable in left hand side menu.
  • Go to user defined variables and select new.
  • Select variable configuration as 1st party cookie 
  • Give cookie name as popUpDisplayed and check url decode cookie option.
  • Save the changes and give the name as popUpDisplayed.

How to monitor the Replication Queues through Java - Adobe CQ5/AEM

Monitoring the Replication Queues through Java - Adobe CQ5/AEM

This post will explain the approach to monitor the Replication Queues of Adobe Experience Manager(AEM) through java

Enable the Remote JMX in the AEM server:

Add the following configurations as part of CQ_JVM_OPTS in AEM startup file (start.sh or start.bat)

-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=50055

e.g.

CQ_JVM_OPTS='-server -Xmx6144m -XX:MaxPermSize=512M -Djava.awt.headless=true -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=50055'

Restart the server.

Configuration.txt:

ServerHost=xxxxxxxxxxx
ServerPort=50055
QueueNames=publish,publish_Dev
Environment=Development
EmailHost=xxxxxx
Email_To=xxxxxx
Email_From=xxxxxxx
QueueThreshold=15

     }catch (MessagingException mex) {
        mex.printStackTrace();
     }
}

}

Configure the data in Configuration.txt file accordingly.
Email will be triggered whenever the configured Queue is disabled, blocked, paused or the pending request is more than the configured threshold.

Executable jar file can be generated for the java class and scheduled for continuous monitoring.

This post will explain, how to populate the current page path to the dialog through EXT JS - Adobe Experience Manager(AEM ) 6.1

Add the listener for the widget and use the below script.

function(widget) {
        var currentPath;
if(CQ.wcm.SiteAdmin.hasListSelection()) {
        var grid = CQ.wcm.SiteAdmin.getActiveGrid();
        var selections = grid.getSelectionModel().getSelections();
currentPath = selections[0].id;
console.log(currentPath);
widget.setValue(currentPath)
}
}
