How do you resolve a split brain situation with HADR?

Hi,

First of all try not to enter into split brain. This is a worst case scenario. DB2 tries to its best not to enter into split brain but if you are in split brain the only option you have is to choose a database as primary and get it up. This information has to immediately conveyed to the application or ETL team and application jobs have to be rerun.

Thanks,
