    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,
    Pandit

    Good DBAs are not formed in a week or a month. They are created little by little, day by day. Protracted and patient effort is needed to develop good DBAs.
