有网友在QQ上找我,说Oracle 7.3的数据库,因为redo异常咨询我是否可以恢复
检查数据库得到以下信息
SVRMGR> select * from v$version; BANNER ---------------------------------------------------------------- Oracle7 Workgroup Server Release 7.3.2.2.1 - Production Release PL/SQL Release 2.3.2.2.0 - Production CORE Version 3.5.2.0.0 - Production TNS for 32-bit Windows: Version 2.3.2.1.0 - Production NLSRTL Version 3.2.2.0.0 - Production 已选择 5 行
数据文件信息
redo信息
跳过redo进行恢复,在resetlogs过程中报rbs表空间坏块,然后通过dul工具获得回滚段名称,然后使用隐含参数屏蔽掉

数据库在启动过程中出现ORA-00600[4306]，导致smon异常。该错误是因为在数据库open过程中smon会清理临时段从而出现该错误,通过设置event跳过，数据库算整体打开，不过在恢复过程中还遇到了

ORA-00600[3600]是因为在offline 回滚段所在表空间锁出现的问题
ORA-00600[4194]是因为回滚段所在的表空间数据文件出现坏块所导致
