Cluster VIP and Preempt

Hi

 

I have two nodes want to configure them as primary and secondary cluster, so;

-can I configure VIP floating between the two nodes (active in primary)?

- if VIP is supported, then is it recommended to configure it or keep each node with different IPs?

- Is there a preempt option in cluster, that the primary (publisher) will be the primary whenever its active?

 

Thanks

Hi

 

There is no much details in documnet about the VIP and how to create it, and preempt too...

I doont know which will be better from design perspective, use different IP in each node, or use the VIP "what is the pros and cons for both"

Re: Cluster VIP and Preempt

But how to configure the VIP and what is the differences between using VIP and separate IP for each node (pros and cons for each), or lets say what are the limitations for each...

Re: Cluster VIP and Preempt

Did you take a look at the user-guide?

 

To config the VIP the nodes MUST also have a separate IP address per interface of their own.
