  • 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
