I know you are on 3.2, but you might check http://docs.alfresco.com. There are multiple clustering topics covered in the official documentation that might be applicable to your install.

Hello,

Thanks for the valuable information, can any one tell us the cluster configuration, step by step on using Alfresco 3.2.2.7 on windows platform.

An early response would be highly appreciated.

Thanx… & Regards

@Tommy,

Double-check that you’ve got the defaultProtocol and inital_hosts set correctly. Also note Björn’s comment in this thread about setting java.net.preferIPv4Stack=true if you are on Linux.

Hi…

I had already setup 2 Alfresco Enterprise 3.1 with trial license in 2 virtual machine and also set the log level of jgroups to INFO but i still can’t see the log message about join and leave node.

Am I miss something?

Thank you
Tommy

No idea. You might have better luck on the Alfresco Forums (http://forums.alfresco.com).

Sorry!

I’d just like to add a few notes to these instructions, to help anyone who might bump into the same problems I did:

* If you configure an Alfresco Cluster setup on Linux, be aware that multicast (UDP) does not work properly if you have IPv6. You should pass this flag to the JVM when starting Alfresco:

-Djava.net.preferIPv4Stack=true

This is not mentioned in the Alfresco documentation as far as I am aware, but is quite clearly noted on the JGroups website.

* Also be aware that the alfresco.tcp.initial_hosts is indeed a required property if using JGroups TCP protocol stack – also noted on the JGroups website.

Thanks for a good tutorial, as usual.

Tuan,

When you changed your props to point to the NAS-mounted directory, did you also move all of the files from /opt/alfresco/alf_data to /alf_data_cluster? Or are you starting with completely clean repository (clean data directory AND clean database)?

Also, make sure the account running Alfresco has full access to the directory (can create/delete files).
