研发中心一台windows2003上跑着oracle和sqlserver的数据库，是一台老机器，已经加挂了3块硬盘，但是最近接到同事请求处理说oracle数据库数据文件所在磁盘快满掉了，问改怎么处理，之前该同事已经咨询过另外一个本部门的同事，本部门同事竟然给答复说没办法处理，处理之后会导致数据库无法使用，我 ！无奈研发同事转问我，但是给她答复说可以处理，于是跑过去看了下机器磁盘信息，发现每块盘都用的差不多快完了，必须购买新硬盘才能处理，无奈之下，研发同事只好选择删除掉1个历史大文档文件，然后先把其中的一个数据文件迁移过去，同时要求申购新硬盘。
今天新硬盘到货，上硬盘并分区，然后准备变更文件存放位置，了解了下该库有3个应用用户，而且数据文件存放的比较混乱，命名也不规范，针对这2点做了统一处理，将数据文件存放到新增加硬盘所在分区，安装用户名称规范存放，文件后增加序号标识。
一下是处理过程，记录在此！
执行如下脚本：
spool f:\mv_datafiles.txt
--Set linesize 200;
Set pagesize 100;
Column username format a8;
Column dtbspace format a8;
Column dtpspace format a8;
Column command format a75;
Select * From v$version;
select a.username,a.default_tablespace dtbspace,a.temporary_tablespace dtpspace from dba_users a where a.username in ('user1','user2','user3') order by a.username;
break on username skip 1;
break on offtbspace skip 1;

查看脱机文件，安装顺序执行脚本，注意在最后os delete的之前最好查看下表空间和数据文件的状态相关信息：
col defaultt_tablespace For a20;
col tablespacestatus For a17;
col defaultt_tablespace For a20;
col file_name For a50;
col datafilestatus For a15;
break On username Skip 1;
break On Default_Tablespace Skip 1;
Select a.Username,
a.Default_Tablespace,c.status tablespacestatus,b.file_name,b.status datafilestatus
From Dba_Users a, Dba_Data_Files b,Dba_Tablespaces c
Where a.Username In ('user1', 'user2', 'user3')
And a.Default_Tablespace = b.Tablespace_Name And b.tablespace_name=c.tablespace_name Order By usern
