通过数据库日志大概可以看出来,由于节点2的分布式事事务异常,而在11.2.0.2中,分布式事务跨节点,引起节点2的pmon清理异常事务,但是由于bug,使得异常事务无法被清理掉,从而引起节点1 crash,节点1 crash之后节点2进行恢复,也因为分布式事务bug,导致smon回滚失败,实例也crash。无法进行回滚导致数据库无法正常启动,通过查询mos发现定位到是Bug 10222544 ORA-600 [k2vpci_2] from multi-branch distributed transaction
ORA-600-k2vpci_2


对于这类问题,由于分布事务无法清理,处理方法就是找出来事务人工提交或者直接屏蔽掉这个事务解决该问题
