Resolution

For each ticket, please attach your portal-ext.properties file, as well as the output of the patching-tool support-info command specific to the environment.

For clustering tickets specifically, please work through the following checklist and include the resulting information when you create a Help Center ticket.

Users Working on Liferay DXP

  1. Are you using Multicast or Unicast?
  2. Have you followed the basic clustering instructions provided in our Knowledge Base?
    1. Installing Liferay DXP in a Clustered Environment

  3. Do you have a cluster license?
  4. Provide us with the complete portal-ext.properties file from all nodes.
    1. Do you have cluster.link.enabled=true in your portal-ext.properties?

Users Working on Liferay Portal

  2. Have you followed the basic clustering instructions provided in our Knowledge Base?
    1. Installing Liferay Portal in a Clustered Environment
    2. Managing Liferay Portal's Distributed Cache
  3. Do you have a cluster license?
  4. Have you installed the Ehcache plugin?
    1. Verify it is the correct version for this portal.
    2. If caching has been customized, please provide the XML files.

    1. Do you have cluster.link.enabled=true in your portal-ext.properties?
  6. Our main objective will be to help troubleshoot a basic cluster of your Liferay Portal environment.
  7. *Have you tried setting up Unicast clustering?

*Please Note: By default, the Liferay platform is tailored for enabling Multicast clustering. Yet, for some users whose environment is not setup to handle Multicast communication—even with Multicast clustering enabled—clustering may not work properly. In this case, we suggest setting up your Liferay cluster using the Unicast option.
