admin_move_table的重组机制验证（失败了）

这次的表，字段多一些，建索引，然后表中行的顺序打乱一下，然后看看移动之后会否变的有顺序。
首先我们创建测试数据库和测试表：
[root@bogon tmp]# touch /opt/var/orgsp2
[root@bogon tmp]# chown db2inst1 /opt/var/orgsp2db2 "create database testmove"db2 connect to testmovedb2 "create tablespace orgsp2 managed by database using (FILE '/opt/var/orgsp2' 64M)"db2 "create table t1 (id int not null primary key,name varchar(20), desc varchar(20)) IN orgsp2"db2 "create table t2 (id int not null primary key,name varchar(20)) IN orgsp2"db2 "create table t3 (id int not null primary key,name varchar(200)) IN orgsp2"db2 "create table t4 (id int not null primary key,name varchar(20),sex smallint,address varchar(200),education char(4)) IN orgsp2"db2 "insert into t4 with c1(col1) as (values(3000) union all select c1.col1 +1 from c1 where c1.col1<3800) select c1.col1,'t4LTT4','0','T4t4T4t4T4t4T4t4T4t4T4t4T4t4t4t4t4t4t4t4t4asdfskdfafasfsfsdfasdfjsadfla s sfdasdfsdfadsfas','benk' from c1"db2 "insert into t1 with c1(col1) as (values(1) union all select c1.col1 +1 from c1 where c1.col1<18000) select c1.col1,'ltt1','this is table t1 ' from c1"db2 "insert into t2 with c1(col1) as (values(1) union all select c1.col1 +1 from c1 where c1.col1<25000) select c1.col1,'this is table t2 ' from c1"db2 "insert into t3 with c1(col1) as (values(1) union all select c1.col1 +1 from c1 where c1.col1<20000) select c1.col1,'T3t3T3t3T3t3T3t3T3t3T3t3T3t3T3t3t3t3t3t3t3t3t3 sdflksadfsa dfjdslkfjsdfjaslkdfsdfsadlfkjsdlkfdsf' from c1"
对表4做一些处理使表4id乱七八糟的哈：

额，只剩下5000个页了，看看能不能admin_move_table成功吧。

注意：初始化的目标表没有索引哦。staging table是有索引的。

现在审视一下表8的数据：
db2dart testmove /DD /tsi 3 /oi 8 /ps 0 /np 0 /v y /rptn t4td.dart
查看导出的数据，可以发现先是id：
Page 0 -> 50-> 150 -> 200 -> 242 -> 250 -> 253 -> 400 -> 600 -> 743 -> 750 -> 760 -> 777 -> 780 -> 785
id: 100->2140-> 6202 -> 8253 -> 9978-29521 -> 29807 -> 30000-51040 -> 59020 -> 65246 -> 71091-300012 ->300313 -> 13227 -> 13992 -> 11036 -> 21076 就是大致是这样的，但是不够有顺序，没有完全遵循顺序应该考虑指定order by子句吗？
重来
首先我们创建测试数据库和测试表：
[root@bogon tmp]# touch /opt/var/orgsp2

20000-20900：

6300-6900：
4880-4990：
删除
5100-5700：

通过导出的文件查看,是符合我们插入的顺序的，然后看看admin_move_table之后它会不会有序呢？

那是不是说admin_move_table它的重点还是在移动而不是在重组哦。。。
关于MDC索引的事情？
最后找到原因了，因为primary key产生的索引就是一个常规索引，不是集群索引。admin_move_table是需要使用一个集群索引的。
引以为戒啊！
