Answer 1

Hi;
This error occurs when you have run a switchover/ failover, you may have two parallel standby's but when you pass the command for switchover the one standby is not aware of what you have done.
The point is that all standby should know who is your primary & standby's should also be aware of each other in their "pfiles" now, you should either recreate the standby or open with reset logs.
ora-600 occurs due to different incarnation.
Hope this will help you
if you switch multiple logfiles in primary, & run >>
alter database recover managed standby database disconnect;
your standby will start syncing.
Hope this will help you
