Re: Issue with I_CmsEventListener in Clustered System

You can  call a JSP/java to send an event from master to slaves.
Another option is pay the OCEE to Alkacon

Hello David,

Thank you for your response. That is an option, but what I really need to know is how I can send events to the slaves using the OpenCms API.

Best regards.
Chema Jiménez Flores.

Hi Chema

We use a table in database to save the changes in the master. The slaves read this table and do the changes in a task every 5 minutes. If you need more information contact me

Regards

Asunto: [opencms-dev] Issue with I_CmsEventListener in Clustered System


Hello,



I have developed a class that implements I_CmsEventListener, and its events include [EVENT_RESOURCE_AND_PROPERTIES_MODIFIED, EVENT_RESOURCE_COPIED, EVENT_RESOURCE_CREATED, EVENT_RESOURCE_DELETED, EVENT_RESOURCE_MODIFIED, EVENT_RESOURCE_MOVED]. If a resource meets a certain condition, another class is executed.



The problem is that in a "cluster" system (with two slave nodes), when editing a resource on the admin node, the I_CmsEventListener class runs only on the admin node and not on the other nodes.



How can I ensure that the I_CmsEventListener class executes on all nodes when modifying a resource?



Thank you very much.

Regards.
