UCMDB 10 high availability versus failover

Jump to solution

Hi,

 

I have been spending some time thinking how to best fulfill the company's need to have a resilient and well-responsive UCMDB 10.01 system. Initially I went in the direction of a reader-writer based setup with two servers behind a load balancer. However at this point I keep thinking of the failover mechanism, where one server is active and one is passive, to add something like this to the mix. Could you please tell me if this is a choice? Is it either HA or DR, or can both be used together? Should I be thinking of a reader-writer setup times 2? Or is every server in the cluster to be set up redundantly?

 

The documentation (at least what I have here in front of me) is not clear on this.

 

Thanks,

Rutger

Hi,

You can't, actually, choose implementation of HA in UCMDB.

UCMDB 9.X and 10.0 were running with active-passive configuration.

Starting from 10.01 and north UCMDB is running with one writer (the one who right in the DB) and at least one reader. In the configuration both servers will be answering on requests from LB. So , be aware that LB need to be reconfigured to "round-robin" with moving to 10.01.

If you have any concerns regarding design on HA please open support case.

Hi Dima,

 

Thanks. Your remark regarding the change in high availability support starting at 10.01 was the one I was looking for.

 

Best,

Rutger
