oracle数据库ORA-600错误问题解决办法

朋友让我帮忙处理一个不能open的库,打开alert日志一看,傻眼了,里面是各种ORA-600的错误应有尽有,被折腾的够惨
故障后重启,无法启动主要表现在block坏块,引起的各种ORA-600等错误

进行了一些恢复处理后,日志中报错
主要体现在进行了不完全恢复,而且应该是对redo进行了重命名或者redo头损坏锁引起的一系列提示

通过一些列方法(bbed,隐含参数等)调整数据库scn,强制启动数据库,报如下错误

SELECT NULL FROM PROPS$ WHERE NAME='BOOTSTRAP_UPGRADE_ERROR'
这里可以发现是数据库在启动的过程中需要执行SELECT NULL FROM PROPS$ WHERE NAME=’BOOTSTRAP_UPGRADE_ERROR’语句，而该语句递归调用了select obj#,type#,ctime,mtime,stime, status, dataobj#, flags, oid$, spare1, spare2 from obj$ where owner#=:1 and name=:2 and namespace=:3 and remoteowner is null and linkname is null and subname is null 语句。既然这样通过一些方法避免数据库启动之时查询SELECT NULL FROM PROPS$ WHERE NAME=’BOOTSTRAP_UPGRADE_ERROR’语句，果然数据库启动成功。

知识点补充
ORA-600 [4502] [a]
Arg [a] ITL entry with a lock count
Meaning: During ITL cleanout we clear all row locks but the ITL entry
     still thinks there is an uncleared lock. Ie: ITL has a locked
     row but there are no locked rows in the block
大体意思是数据库发现undo 的itl已经被清除，但是block中的itl依然存在，从而出现ORA-600[4502],引起该问题除bug外主要原因是坏块

ORA-600 [2037] [a] [b] [d] [e] [f] [g]
Arg [a] Relative Data Block Address (RDBA) that the redo vector is for
Arg [b] The Block format
Arg 1 RDBA in the block itself
Arg [d] The block type
Arg [e] The sequence number
Arg [f] Flags, if set
Arg [g] The return value from the block head/tail checker.
DESCRIPTION:
  During recovery we are examining a block to ensure that it is not
  corrupt prior to applying any change vectors.
  The block has failed this check and this exception is raised
大体意思是在恢复过程中，正在检查的块，以确保它在应用任何变化向量之前不损坏。如果检查失败排除该异常ORA-600[2037],引起该问题除bug外主要原因是坏块

ORA-600 [kcbzpbuf_1],[a],[b]
Arg [a] Corruption reason
Arg [b] Calculate checksum flag
 
Corruption reason:
#define KCBH_GOOD    0                                     /* block is valid */
#define KCBH_ZERO    1             /* block header was entirely zero on disk */
#define KCBH_BROKEN  2      /* corruption could be from a partial disk write */
#define KCBH_CHKVAL  3               /* The check value for the block failed */
#define KCBH_CORRUPT 4     /* this is the wrong block or is not a data block */
#define KCBH_ZERONG  5               /* all zero block and it is not allowed */
 
Calculate checksum flag:
The possible values are 1 (Generate Checksum - db_block_checksum is enabled - default value)
                        0 (do not generate checksum - db_block_checksum=false)
kcbzpbuf_1是该错误的源码函数

ORA-600 [17182] [a] [b] [d] [e]
DESCRIPTION:       
  Oracle has detected that the magic number in a memory chunk header has been overwritten.
  This is a heap (in memory) corruption and there is no underlying data corruption.
  The error may occur in the one of the process specific heaps
  (the Call heap, PGA heap, or session heap) or in the shared heap (SGA).
1
ORACLE 发现在内存中重要的块头被重新,但是没有基础数据损坏,大部分和数据块或者内存损坏有关系.


ORA-600 [4552] [a] [b] 1 [d] [e]
1
DESCRIPTION:
  This assertion is raised because we are trying to unlock the rows in a
  block, but receive an incorrect block type.
  The second argument is the block type received.
ORACLE尝试对某行进行解锁但是接收到了不正确的数据块类型,Arg [b]是接收到的数据块类型

ORA-600 [2662] [a] [b] [d] [e]
DESCRIPTION:
 
  A data block SCN is ahead of the current SCN.
 
  The ORA-600 [2662] occurs when an SCN is compared to the dependent SCN
  stored in a UGA variable.
 
  If the SCN is less than the dependent SCN then we signal the ORA-600 [2662]
  internal error.
 
ARGUMENTS:
  Arg [a]  Current SCN WRAP
  Arg [b]  Current SCN BASE
  Arg 1  dependent SCN WRAP
  Arg [d]  dependent SCN BASE
  Arg [e]  Where present this is the DBA where the dependent SCN came from.
主要的含义就是oracle文件头scn比某个block dependent scn小从而出现该问题
