Load balance liferay problem with index data

[6年前 に mika mika によって更新されました。]

Hi everybody,
I have two sevrer liferay tomcat and one proxy to load balance between two node server. both server liferay are configured same database, same solr sever, same data location. But when I edit something like webcontent, authen, ldap , disable app, etc... It seem to not synchronize between two node sever. I use Liferay 7 ga3
Please help me, thank a lot!

You need the new cluster support module that was recently announced...

Basically when you retrieve data from the DB, liferay leverages ehcache to keep a copy locally so it can use it for subsequent requests. When you change the value, Liferay will purge it from ehcache to get rid of the "stale" data.

When you're in a cluster, this same activity needs to occur for writes, but all nodes need to be notified to purge from their own local ehcaches. If that cluster notification mechanism is not in place, a node will not know that its data in the cache is stale and will continue to return it.

The new cluster support module restores this cluster notification mechanism.








Come meet me at 2017 LSNA!

Hi David,

Clustering is only supported in CE 7.0 GA5+.
Since this version is not released yet, it obviously won't work.

Please note that there is a branch which you could use till GA5 is released:
