ORA-00756 ORA-10567故障数据0丢失恢复

惜分飞 — Sun, 29 Jun 2025 01:38:10 +0000

客户虚拟化故障修复之后,数据库启动报ORA-600 kcratr_scan_lastbwr错误

这个是一个比较常见的错误,一般recover 下就ok了,但是有些时候会出现ORA-600 3020或者类似ORA-00756 ORA-10567的错误,比如这次不幸就遇到了该错误

SQL> recover database;
ORA-00283: recovery session canceled due to errors
ORA-00756: recovery detected a lost write of a data block
ORA-10567: Redo is inconsistent with data block (file# 10, block# 4005760, file

ORA-10564: tablespace PACS55
ORA-01110: data file 10: '/u02/oradata/pacsdb/pacs55.4.dbf'
ORA-10561: block type 'TRANSACTION MANAGED INDEX BLOCK', data object# 76649

然后尝试单个文件recover恢复

确定数据文件本身没有坏块,只是redo写丢失或者某种bug导致少量block应用redo的时候异常,而且报错是index,直接通过底层处理报错的block,让其这些报错的block直接不应用日志,然后完成recover操作,其他数据块数据不会丢失(最大限度减少损失,而不是直接修改文件头scn,或者强制拉库的方式来处理)

至此该库完美恢复业务可以直接使用,业务数据0丢失.这次运气比较好,如果是表数据异常,可能会麻烦一点,但是也可以最大限度恢复(肯定比强制拉库,或者修改文件头的方式效果好)

通过上述分析,确认还有I_OBJ2和I_COL3这两个核心index异常,参考:bootstrap$核心index(I_OBJ1,I_USER1,I_FILE#_BLOCK#,I_IND1,I_TS#,I_CDEF1等)异常恢复—ORA-00701错误解决进行处理,数据库可以正常导出
