ORACLE REAL APPLICATION CLUSTER

Oracle database administration (DBA), Oracle RAC

Hi to all In Oracle RAC what is menat by split brain syndrome ? What happens when it happens? I mean to say RAC database hangs or crashes ?
thanks in advance

It means that you have two versions of CRS running at the same time. This can happen if the devices on your network come up slower than your services. If CRS detects it, they all shut down and the database does not come up. Put in a sleep init.crs file in your rc.d directory (if UNIX) to delay RAC startup until all your devices come on line.
