The DR mechanism of Qlik Replicate

[yit-huang]

How does Qlik Replicate perform Disaster recovery procedure? if we pre-created a secondary Qlik Replicate in DR region, how to synchronize the Configuration on primary region to DR region?

Hi @yit-huang
Thank you for posting your question.

This question is best answered by a professional services specialist who has knowledge about your environment,

In general, Replicate runs within the DR environment.

you can use high availability cluster and install a replicate to work with the cluster.

the DR mechanism will trigger the failover.

Can you please let us know the source, target, and DR you are using?

This way we can send you relevant links from the user guide.

Thank you

Hi @yit-huang

Please refer to these sections in our user guide for details on setting up Replicate in a high availability cluster:

Thanks,

Hello @yit-huang

Like Dana mentioned we support high availability cluster, where the data drive gets shared between nodes as failover happens. This is managed by Windows failover clustering.

Thank you,

Hi Dana,

Do we need Linux cluster suits to implement DR or HA ? also SAN storage ? NAS won't work ?

here are several commercially available clustering solutions for Linux including Veritas Cluster Server, Red Hat Cluster Suite and IBM HACMP for Linux.

Hi @nareshkumar 

You cannot have more than one web UI server running against the same Replicate server (where the data actually flows), so yes, a fail over cluster is the only high availability option.

Please refer to the documentation link in my post above for the details. At the top left of the screen you can change it to reflect the version of Qlik Replicate you are currently running as details may have changed.

Beyond that I suggest you work with pre-sales if you're not an existing customer or our Professional Services team if you are a customer in order to determine the best implementation options for your needs.

Thanks,

Dana

Hello @nareshkumar 

As mentioned in the Qlik Doc and Suggestion Shared by the TSE Further addition to that .

here are several commercially available clustering solutions for Linux including Veritas Cluster Server, Red Hat Cluster Suite and IBM HACMP for Linux.

Above mentioned Solution have same as cluster environme  Dr is Bit different as Qlik Stored info on the data Folder so you must use something which Copy block from Data to DR DATA folder.

let say you sync up the data by storage utility at 12:00 AM and you require DR in case of unforeseen event at 4 :00 and switchover to DR then task may be processing changes from the stored info at 12:00 PM. 

in case of Switchover, it may work logically but in case of real scenario it would not work.
