达梦数据库日志错误记录:

select * from v$datafile ;
select * from v$buffer_lur_first ;
检查出错记录 page(group_id,id,page_no )

dmdbchk path=/data/dmdata/DAMENG/dm.ini file_path=/data/dmdata/DAMENG/pagecheck01.dbf

使用dmrman 进行库恢复.
restore page[5,0,588] database '/data/dmdata/DAMENG/dm.ini' from backupset '/data/dmbak/db_full_bak_for_restore' ;

recover page[5,0,588] database '/data/dmdata/DAMENG/dm.ini';
