Not neccessarily.....
It depends on the argument which is followed after the ora-600 error.
If the args[17000......more] and args[7445] you are right it may need recovery ...It may
corrupt index (I have faced)....
I feel arg[6033] is because of the core dump?.If so just bounce the db once.It will work.
What corresponding trace file says?.can you post that.
Thanks.
