ORA-01157: cannot identify/lock data file 6 - see DBWR trace file

2个月以前使用swingbench的时候,cc这个user创建17GB的测试数据(ccdata.dbf),后面测试完成后,

因为是测试机,空间不足,直接手动rm –rf /Data/oradata/ora11g/ccdata.dbf这个文件

 

之后因其他测试时重启DB时碰到了ORA-01157错误,

ORA-01157: cannot identify/lock data file 6 - see DBWR trace file

ORA-01110: data file 6: ‘/Data/oradata/ora11g/ccdata.dbf‘

root case:手动ccdata.dbf文件,既然问题已经知道,那就下手处理吧:

ora11g</Data/oradata/ora11g>$sqlplus / as sysdba

至此问题已经解决

测试库,暂时用startup force启动一次吧:

警示:正式库DB万万不要手动rm 数据文件
