rac数据库多个节点均处于open状态,数据查询正常,但是应用入库有些时候会失败报类似ORA-01187: cannot read from file because it failed verification tests错误：
故障最初原因是由于有坏盘,换盘之后,有两个节点数据实例crash

但是数据库人工启动成功,查询所有数据文件均处于online状态
可是有部分入库进程非常慢大量等待在enq:HW – contention
所有数据库节点alert日志偶尔报ORA-01186: file 1399 failed verification tests等错

基于这种情况,初步判断：
1. 是由于该集群本身多节点(6个节点),只要有节点是open状态,其他节点关闭再启动依旧可以正常启动,但是无法写入数据到报ORA-01207错误的数据文件中(可以读取数据).
2. 如果所有节点关闭关闭,然后数据库无法正常启动会报ORA-01207: file is more recent than control file错误
这样的情况,根据以往经验,ORA-01207: file is more recent than control file通过重建ctl即可恢复,先关闭所有节点,然后尝试启动一个节点

和预期的一样,重试重建ctl,然后数据库报ORA-00600 [krhpfh_03-1210]错误

这里的提示是有fhcpc和fhccc值不对导致,通过bbed查看相关值
BBED> set file 1399 FILE# 1399 BBED> p kcvfhccc ub4 kcvfhccc @148 0x00043227 ===>274983(10进制) BBED> p kcvfhcpc ub4 kcvfhcpc @140 0x00043218 ===>274968(10进制)
报错比较明显通过bbed修改这两个值
