Troubleshoot AEM Forms on JEE Installation

When TCP locators remove an AEM Forms server node from the cluster (due to hearbeat timeout or any other issue) and the node rejoins the distribution system, caching does not work on the node.

Users experiences an error message similar to the following:

In case caching is not working properly, you must restart the server node. On successful restart, the node joins the cluster and cache starts working. 

The Configuration Manager fails when the user changes the JBoss default port from 8080. It results in no reponse from the JBoss service.  

The issue occurs when the user modifies the JBoss listen port in the lc_turnkey.xml file from 8080 to other port.

For example, lc_turnkey.xml: Port 8080 --> 9999

<socket-binding name="http" interface="any" port="${jboss.http.port:8080 --> 9999}"/>

User experiences an error message similar to the following:

Before you change the default port, you must know that the port change is supported only for http, not for https.

To successfully modify the default JBoss port:

• Modify the port in lc-turnkey.xml file: 
  For example, lc_turnkey.xml: Port 8080 --> 9999
  <socket-binding name="http" interface="any" port="${jboss.http.port:8080 --> 9999}"/>
  
  
• Add a property turnkey.jboss.webport  in the lcm.properties file under the Configuration Manager with the value of new port.
  For example, turnkey.jboss.webport=9999

• Run Configuration Manager to apply the modifications.
