Synchronization in Qlik Sense multi-node setup

Mon, 22 May 2017 09:14:10 GMT

Hello,

We have two multi-node setups, each has a central node and a Reload node (Scheduler + Engine) and the default sync rule to sync all apps to the Rim is enabled. The first one is working but the second one doesn't synchronize the apps.

I would like to understand how the synchronization is working. I know that during the initialization of the scheduler node, there is a general synchronization of the repository.

When are the apps synchronized and how frequently are they synchronized ?

After validate the sync rule, will the synchronization start immediately ?

If not, is it possible to force the start of a synchronization ?

My last question is how does the synchronization work in details ? And especially for these ports : 5050, 5151, 4241,4242.

Thanks,

Thibaut SCHUELLER

Hi @felipeseberhard,

This post was from 2017 and refers to another architecture model called Synchronized Persistence which does not exist anymore since the version Qlik Sense June 2018.

I believe you are referring to the issue posted here https://community.qlik.com/t5/Deployment-Management/QMC-not-sync-between-cluster-nodes/td-p/1798528

In that case the symptoms you described are more related to a node (or several) getting disconnected from the Qlik Sense Repository Database.

Take a look at this link for more information: https://community.qlik.com/t5/Knowledge-Base/Qlik-Sense-Randomly-some-streams-are-not-available-in-the-Hub/ta-p/1778814

Hope this helps!
