现象：
RAC环境，数据文件状态变为recover，查看alert日志有如下报错：

分析：
1.查看所有节点的messages系统日志、asm日志均没有出现错误信息。
2.查看DG的raw权限，也没有异常。
/dev/raw/raw6
/dev/raw/raw7
3.该Datafile为autoextend模式。
SQL> select file_name,autoextensible from dba_data_files where file_name like '+TJDISK/tj/datafile/ntj_index03.301.757894747';

FILE_NAME

+TJDISK/tj/datafile/ntj_index03.301.757894747
YES

最后查了下Metalink，怀疑是命中了Oracle的一个BUG：Bug 16734525或Bug 9357097（Bug 16734525 is the duplicate of Bug 9357097）。

ANALYSIS:--------------------
1. Matches the bug 9357097: SMALL BEEHIVE: FAILURE TO REFRESH FILE SIZE DUE TO SPACE OFFLINES DATAFILE
Need to confirm from DEV as audit file space issues were not there
2. Not using role separation and oracle executable is with correct permissions
3. CT is not sure if dbv or rman validate was run on the problematic datafiledue to media error

Range of versions believed to be affected <-- 12.1下的版本都有可能命中

This issue is fixed in <-- 12.1.0.1 11.2.0.2中已修复
?12.1.0.1 (Base Release)
?11.2.0.2 (Server Patch Set)

DBWR can offline the datafile with message "Automatic datafile offline due to media error"
if file size refresh fails with error ORA-1148.
As the file is offline, subsequent attempts to read the affected file produce
error ORA-372 or ORA-376 requiring media recovery.
解决方法：
临时解决方法是将手动将文件online，
Oracle并没有提供专门的补丁，需要升级到对应版本才能彻底解决（11.2.0.2）。

诊断时在ASM实例中执行了以下脚本。
SPOOL ASM_FIRST<instance#>.HTML
SET MARKUP HTML ON
set echo on
set pagesize 200
alter session set nls_date_format='DD-MON-YYYY HH24:MI:SS';
select 'THIS ASM REPORT WAS GENERATED AT: ==)> ' , sysdate " " from dual;
select 'HOSTNAME ASSOCIATED WITH THIS ASM INSTANCE: ==)> ' , MACHINE " " from v$session where program like '%SMON%';
