hi all
i have two clustered liferay 6.5 servers ,two database server Master/Master replication relationship & have solr Server

when i add or modify any journal articles i can't see the changes on the next server till i go to control panel >> Server administration >> and execute the "Clear content cached across the cluster."

and this my portal-ext.properties is



jdbc.default.driverClassName=com.mysql.jdbc.Driver
jdbc.default.url=jdbc:mysql://xxx.xxx.xxx.122:3306/tabuk_db?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false
jdbc.default.username=user_a
jdbc.default.password=1234a5678

jdbc.one.driverClassName=com.mysql.jdbc.Driver
jdbc.one.url=jdbc:mysql://xxx.xxx.xxx.119:3306/tabuk_db?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false
jdbc.one.username=user_a
jdbc.one.password=1234a5678

jdbc.two.driverClassName=com.mysql.jdbc.Driver
jdbc.two.url=jdbc:mysql://xxx.xxx.xxx.122:3306/tabuk_db?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false

Looks like you're using default multicast groups/ports then?
    multicast.group.address*...
    multicast.group.port*...

    multicast.group.address["multi-vm"]=239.255.0.5
    multicast.group.port["multi-vm"]=23305


Can you make sure your two nodes can communicate through these addresses/ports

I believe you also want to turn on cluster link too. I'm not sure all the things affected by it, but I know managing scheduled jobs is part of it.

    #
    # Set this to true to enable the cluster link. This is required if you want
    # to cluster indexing and other features that depend the cluster link.
    #
    cluster.link.enabled=false

It works for CE too.

You've mentioned that you've setup a Liferay in cluster? How did you set it up? Did you cluster your application server (e.g. JBoss cluster)? If you did, you may run into some trouble.

Liferay tries to get data from the cache before going to the database. So, you'll have to share the cache by activating clusterlink.

If you activate Clusterlink, be sure to check that the data is not being written to the 2 Masters separately because it may result in duplicate entries.

i solve the problem by adding the folloing to my portal-ext and adding with myehcache folder to the location /liferay-6.5/tomcat-6.0.26/webapps/ROOT/WEB-INF/classes i include the file in the attachment

but i still don't know what the wrong with the default value ??

Liferay's default is just for a standalone configuration because most small users aren't clustering.

Hi,

Exactly the same problem here : journal article is not updated on my LR node #2 until I hit the "clear content cached accross the cluster" button. So 'I'm really happy you found a solution emoticon

I'm using jgroups to handle nodes communication - is this kind of network communication compliant with your settings ?

I got this same issue in the non clustered environment as well. Our related assets in a web content on a page won't get updated unless we do a clear cache or turn off caching in the templates.
