Qlik HA Installation

SreehariPV — Wed, 07 Feb 2024 06:23:17 GMT

I already have Qlik Replicate (May 2022 (2022.5.0.499)) installed on a primary node, I want to add Qlik Replicate HA on another node.

Whate are the pre-requisites for this, and important things to be considered before doing the same.

Is separate license required for HA installation?
because I'm getting the below warning in HA Server

Hi @SreehariPV The error is not due to the license but the user account you logged in as. Are you opening it from the server as the user that installed Replicate?

I'm having an instance/ primary server where i have my qlik running and I want an HA in secondary server, I have a shared folder where I'm setting all configs like masterkey. my question is do the versions have to match or can I have a newer version in secondary?

Hi @SreehariPV

The versions need to match. The structure of the data folder and files can be different between versions.

1) is there any minimum number of instances required while setting up HA, can I have only 1 primary node and 1 secondary node( were HA is setup). Or is there anything were min.requirement is 3?

Hi @SreehariPV

I have only seen configurations with 2 fail over nodes. Seems like 3+ should work as well, provided they all share the same data directory, but only one node can be active at a time, there is no load-balancing between servers. You might want to check with our Professional Services team to explore all your disaster recover options. Please reach out to your Account Manager to contact them.

@Dana_Baldwin in 4th step

Step 4: Enable different console addresses in a high availability environment

where should I run the command in primary or secondary node?

Hi @SreehariPV

You will run that command on each machine in the cluster as the user interface service that hosts the web UI is local to each server. Run the command on one server, fail over to the other node and then run the command there.

Thanks,
