Tagshow (event, '% Ca % fd % be % DD % BF % e2 ');
} "Href =" http://www.cnblogs.com/wuhenke/admin/javascript:; "target =" _ Self ">Database: Alter database open. Error:

ORA-01113: file 7 media recovery required

ORA-01110: data file 7 : 'e: oracle \ product \ 10.2.0 \ oradata \ orcl \ test01.dbf '.

This is because the database considers this data file to be damaged and requires recover command {
tagshow (event, '% B1 % B8 % B7 % dd ');
