Risk of split brain scenario

704111Apr 21 2010 — edited May 14 2010

Hi,

We have come across a hughe concern within my company. We are running RAC and Dataguard on RHEL 5.3 and 10.2.0.4 PSU 2. We have configured both primary and standby as RAC databases and have run into a situation where do a failover-test. The primary fails over as expected, but the reinstate-command with the broker fails to determine the failed database is no longer a primary and wants to open the database in read / write mode. This is very dangerous and I was wondering if anyone has come across this? When using observer and FSF it has worked as expected.

Desperate for suggestions!

Regards,

Martin
