Tags:ORA-01157 ORA-01110 无法 识别 锁定 数据 文件

之前在生产中遇到同样报错,用户在客户端查询表中数据,报如下错误:
Errors in file /oratrace/xxx/diag/rdbms/xxx/xxx2/trace/xxx2_dbw0_8454382.trc:
ORA-01157: cannot identify/lock data file 366 - see DBWR trace file
ORA-01110: data file 366: '/dev/rrpt001vg05'


这个报错是由于,2节点重启后,包含/dev/rrpt001vg05这个lv的lv没有online导致。varyonvg vg后,还是不能访问这个vg下的lv。在数据库内执行alter system check datafiles命令后,可以访问所有的数据文件。
该命令一般用于rac环境中,比如说其中一个节点无法访问某一个datafile(只有这个节点无法访问,其余节点是能访问的),无法访问的这个节点上就可以使用ALTER SYSTEM CHECK DATAFILES这个命令来更新实例的sga信息,更新信息的来源 是控制文件。


先做个实验将故障重演一遍:
