Database cache is not cleared properly across the cluster https://liferay.dev/c/message_boards/find_thread?p_l_id=119785294&threadId=120557470 2026-04-04T12:44:17Z 2026-04-04T12:44:17Z Rafał Pydyniak https://liferay.dev/c/message_boards/find_message?p_l_id=119785294&messageId=120561893 2021-01-27T07:49:08Z 2021-01-27T07:49:08Z

<p>Hello,</p> <p> </p> <p>yes I did that, thanks for the answer anyway!</p> <p>After all it seems that the issue was different timezone set on one of the servers (in setenv.sh). It seems to be working fine after I changed that</p> <p> </p> <p>Thanks!</p>

<p>Hello,</p> <p> </p> <p>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.</p> <p>Everything seems to be working fine - ES indexes seems to be working fine, documents &amp; 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.</p> <p>From what I understand from the documentation Liferay should invalidate cache on other nodes so the other nodes can fetch &quot;fresh&quot; data from the database instead of using cache.</p> <p>I also have following properties in portal-ext.properties connected to clustering (on both nodes these are the same):<br />cluster.link.enabled=true<br />ehcache.cluster.link.replication.enabled=true<br />web.server.display.node=true<br />cluster.link.channel.properties.control=/home/liferay/portal_ceGA7/unicast.xml<br />cluster.link.channel.properties.transport.0=/home/liferay/portal_ceGA7/unicast.xml</p> <p> </p> <p>Any ideas what else could've been wrong?</p>
