Ora-1157 ora-1110错误解决案例一枚

1、数据库打开报错如下：

SQL> alter database open;

alter database open

*

ERROR at line 1:

ORA-01157: cannot identify/lock data file 4 - see DBWR trace file

ORA-01110: data file 4: '/weblogic/oradata/orcl/users01.dbf'

2、查看告警日志，同样报错：

Thu Nov 10 17:58:14 2016

alter database open

Thu Nov 10 17:58:14 2016

3、因为报错linux错误，所以查看具体的数据文件权限，发现数据文件权限都变成了weblogic：

[root@slave1 weblogic]# ll

total 24

drwx------. 2 weblogic weblogic 16384 May 6 2016 lost+found

drwxrwxr-x. 3 weblogic weblogic 4096 May 6 2016 Oracle

drwxr-xr-x. 3weblogic weblogic 4096 Aug 16 10:20 oradata

4、修改数据文件权限：

[root@slave1 weblogic]# chown -R oracle:oinstall Oracle/

[root@slave1 weblogic]# chown -R oracle:oinstall oradata/

[root@slave1 weblogic]# ll

total 24

drwx------. 2 weblogic weblogic 16384 May 6 2016 lost+found

drwxrwxr-x. 3 oracle oinstall 4096 May 6 2016 Oracle

drwxr-xr-x. 3 oracle oinstall 4096 Aug 16 10:20 oradata

5、成功打开数据库，告警日志也没有再次报错：

SQL> alter database open;

Database altered.
