表压缩及索引重建--子分区表

1.查看表空间使用率，对比压缩前后以及索引重建前后表空间的一个变化

SELECT Upper(F.TABLESPACE_NAME)         "表空间名",
       D.TOT_GROOTTE_MB                 "表空间大小(M)",
       D.TOT_GROOTTE_MB - F.TOTAL_BYTES "已使用空间(M)",
       To_char(Round(( D.TOT_GROOTTE_MB - F.TOTAL_BYTES ) / D.TOT_GROOTTE_MB * 100, 2), '990.99')
       || '%'                           "使用比",
       F.TOTAL_BYTES                    "空闲空间(M)",
       F.MAX_BYTES                      "最大块(M)"
FROM   (SELECT TABLESPACE_NAME,
               Round(Sum(BYTES) / ( 1024 * 1024 ), 2) TOTAL_BYTES,
               Round(Max(BYTES) / ( 1024 * 1024 ), 2) MAX_BYTES
        FROM   SYS.DBA_FREE_SPACE
        GROUP  BY TABLESPACE_NAME) F,
       (SELECT DD.TABLESPACE_NAME,
               Round(Sum(DD.BYTES) / ( 1024 * 1024 ), 2) TOT_GROOTTE_MB
        FROM   SYS.DBA_DATA_FILES DD
        GROUP  BY DD.TABLESPACE_NAME) D
WHERE  D.TABLESPACE_NAME = F.TABLESPACE_NAME
ORDER  BY 1

2.查看数据文件大小(rac查看asm磁盘大小)，方便resize完数据文件对比大小

SELECT tablespace_name, 
file_id, 
file_name, 
round(bytes / (1024 * 1024), 0) total_space 
FROM dba_data_files 
ORDER BY tablespace_name;

3.创建分区测试表

create table sales_part_test
(
  prod_id       NUMBER not null,
  cust_id       NUMBER not null,
  time_id       DATE not null,
  channel_id    NUMBER not null,
  promo_id      NUMBER not null,
  quantity_sold NUMBER(10,2) not null,
  amount_sold   NUMBER(10,2) not null
)
partition by range(time_id) subpartition  by range  (time_id)  --指定主表分区和子分区分区方式都是:范围分区，并按照列time_id 进行范围划分
( 
 partition sales_part_1998 values less than (TO_DATE('1999-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS'))
 tablespace   HZH0528

   subpartition sales_part_1998_02 values less than ( TO_DATE('1998-03-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS'))  tablespace   HZH0528,

4.创建分区局部索引

create index idx_sales_sales_part_test on sales_part_test (time_id)local;

5.插入数据

insert into sales_part_test select * from sh.sales;

6.分析表

analyze table sales_part_test compute statistics;

7.查看分区表是否压缩,以及生成压缩语句

select table_owner,table_name,partition_name,subpartition_name,tablespace_name,compression,compress_for,'alter table '||TABLE_OWNER||'.'||TABLE_NAME||' move subpartition '||SUBPARTITION_NAME||' tablespace '||TABLESPACE_NAME|| '  compress for oltp parallel 4;' from dba_tab_subpartitions where table_name = 'SALES_PART_TEST'  ORDER BY SUBPARTITION_NAME;

8.执行子分区压缩，这种压缩尽量放在后台执行

alter table HZH.SALES_PART_TEST move subpartition SALES_PART_1998_01 tablespace HZH0528 compress for oltp parallel 4;
alter table HZH.SALES_PART_TEST move subpartition SALES_PART_1998_02 tablespace HZH0528 compress for oltp parallel 4;
alter table HZH.SALES_PART_TEST move subpartition SALES_PART_1998_03 tablespace HZH0528 compress for oltp parallel 4;

alter table HZH.SALES_PART_TEST move subpartition SALES_PART_2001_12 tablespace HZH0528 compress for oltp parallel 4;

9.查看压缩状态

select table_owner,table_name,partition_name,subpartition_name,tablespace_name,compression,compress_for,'alter table '||TABLE_OWNER||'.'||TABLE_NAME||' move subpartition '||SUBPARTITION_NAME||' tablespace '||TABLESPACE_NAME|| '  compress for oltp parallel 4;' from dba_tab_subpartitions where table_name = 'SALES_PART_TEST'  ORDER BY SUBPARTITION_NAME;

10.查看索引状态，此时如果不知道索引名字，可以从dba_indexes视图中去查询表下有无索引

select b.index_name, b.partition_name, b.subpartition_name,b.status from dba_ind_subpartitions b where b.index_name in ('IDX_SALES_SALES_PART_TEST') and status<>'USABLE' order by 1,2;

11.生成索引重建语句

select INDEX_OWNER,INDEX_NAME,PARTITION_NAME,SUBPARTITION_NAME,HIGH_VALUE,SUBPARTITION_POSITION,STATUS,TABLESPACE_NAME,'alter index '||INDEX_OWNER||'.'||INDEX_NAME||' rebuild subpartition '||subpartition_name||' parallel 4 online;' from dba_ind_subpartitions where index_name='IDX_SALES_SALES_PART_TEST'  and index_owner='HZH' and status<>'USABLE'

 12.重新查找重建后的索引状态，这两个语句都可以

select b.index_name, b.partition_name, b.subpartition_name,b.status from dba_ind_subpartitions b where b.index_name in ('IDX_SALES_SALES_PART_TEST') and status<>'USABLE' order by 1,2;

select INDEX_OWNER,INDEX_NAME,PARTITION_NAME,SUBPARTITION_NAME,HIGH_VALUE,SUBPARTITION_POSITION,STATUS,TABLESPACE_NAME,'alter index '||INDEX_OWNER||'.'||INDEX_NAME||' rebuild subpartition '||subpartition_name||' parallel 4 online;' from dba_ind_subpartitions where index_name='IDX_SALES_SALES_PART_TEST'  and index_owner='HZH' and status<>'USABLE' 

13.压缩完子分区就可以进行数据文件resize，如何resize见另一篇文章，是分区压缩完，数据文件resize的，方式相同
