ORA-600 3600恢复—-resetlogs scn异常

发表于 2022 年 1 月 28 日 由 惜分飞

由于客户误操作,在有文件offline的情况下进行resetlogs操作,导致有文件resetlogs scn不对
20220128000040

尝试offline异常文件,均报ORA-600 3600

因为resetlogs scn不对,也无法正常重建控制文件,对于这样的case,可以Oracle Recovery Tools进行修复resetlogs scn,然后直接open库

这个对象为核心对象obj$的index,无法直接rebuild,当然可以通过参考以前blog文档进行重建:bootstrap$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,直接对该坏块进行修复.

Oracle Recovery Tools恢复—ORA-00704 ORA-01555故障

发表于 2021 年 3 月 14 日 由 惜分飞

由于虚拟化环境使用了精简模式(预分配),后面出现分布式存储空间不足,导致虚拟化环境中的数据库服务器异常,通过一系列操作恢复好系统,发现数据库无法open,请求我们给予解决
通过我们的Oracle Database Recovery Check脚本分析,分析文件的checkpoint scn 有部分3月2日,还有一些是2月28日,是严重不一致,而且对应的归档也丢失
