【ORACLE数据库恢复】ORA-00600[KCLCHKBLK]

ORA-600: internal error code, arguments: [kclchkblk_3/4]错误的相关症状可能如下： 当从备份中restore过数据库并做了一个incomplete recovery不完全恢复时 以resetlogs 选项打开数据库 在打开数据库之后可能遇到以下的错误： ORA-00600 [kclchkblk_4] ORA

ORA-600: internal error code, arguments: [kclchkblk_3/4]错误的相关症状可能如下：

• 当从备份中restore过数据库并做了一个incomplete recovery不完全恢复时
• 以resetlogs 选项打开数据库
• 在打开数据库之后可能遇到以下的错误：
  • ORA-00600 [kclchkblk_4]
    ORA-00600 [2662]
• 其错误堆栈stack trace 为kclchkblk kcbzib kcbgcur ktfbhget ktftfcload

触发该错误的原因是：

ORA-600[KCLCHKBLK_4]是由临时文件中的块上的SCN过高引起，? ORA-600[2662]错误也是类似的原因。

该问题可能是由于在OPEN RESETLOGS之后临时文件temporary file没有正确初始化所引起

这个ORA-00600[KCLCHKBLK]中的KCLCHKBLK 代表 check block scn after a disk read

ORA-600 [kclchkblk_3] [a] [b] [c]

The error is reported when the block SCN is less than the last block SCN.
Called by the cache layer after reading a block from disk.

The block SCN is checked to make sure it is not greater than the recent
SCN and not less than the last block SCN seen.

ARGUMENTS:
Arg [a]? Current SCN WRAP
Arg [b]? Current SCN BASE
Arg [c]? Block type

FUNCTIONALITY:
Check Block scn

IMPACT:
MEMORY CORRUPTION
POSSIBLE PHYSICAL CORRUPTION
