ORA-00205: error in identifying controlfile, check alert log for more info
Which view would you query at this stage to investigate this missing control file?
A) V$INSTANCE
B) V$CONTROLFILE
C) DBA_CONTROL_FILES
D) V$DATABASE_PROPERTIES
E) V$CONTROLFILE_RECORD_SECTION
答案: B
当控制文件丢失时,你可以通过动态性能视图V$controlfile来查看丢失的控制文件
疑问:v开头视图绝大部门来自控制文件或内存,如果控制文件丢失了,这个视图还能查吗
无C选项对应视图
查询v$controlfile_record_section可以得出控制文件的使用情况
