Hello,
I have a question. I have created clustered environment with two
Liferay instances (hosted on two different servers, same subnet). I'm
using unicast over TCP for cluster link with TCPPing option. I'm using
the same database, I have shared directory for data and I'm using
same, remote ElasticSearch instance. When I start the servers there
are messages that suggest proper working on for the cluster
(JgroupsReceiver Accepted view... with both servers). The Liferay
version is 7.0.6 CE.
Everything seems to be working fine - ES indexes seems to be working
fine, documents & media seems to be working fine as well. The only
thing I have problem with are web contents. When I update a web
content on one node I can't see the changes right away on second node
- if I want it to be available right away I need to clear the database cache.
From what I understand from the documentation Liferay should
invalidate cache on other nodes so the other nodes can fetch
"fresh" data from the database instead of using cache.
I also have following properties in portal-ext.properties connected
to clustering (on both nodes these are the same):
cluster.link.enabled=true
ehcache.cluster.link.replication.enabled=true
web.server.display.node=true
cluster.link.channel.properties.control=/home/liferay/portal_ceGA7/unicast.xml
cluster.link.channel.properties.transport.0=/home/liferay/portal_ceGA7/unicast.xml
Any ideas what else could've been wrong?
