How to identify which is primary and secondary datacenter of our instance?

[Suggy]

In support portal, I see this. Which is primary DC vs Secondary DC?

Hi, if you check /stats.do the 'active' instance can be identified but the name of the node that you are connected too.

You can also identify from 'sys_cluster_state' table, nodes from the 'active' data center will show as schedulers = 'any'.
