一、定义说明
oracle数据库中，存在多种对象，最常见的表和索引，索引的目的是为了加快查询；oracle建议一个表>2g时，就建议进行分区，分区表的好处此处省略，分区表有维护操作，但是某些维护操作对整个表的索引维护造成巨大开销，因此本地索引就是解决分区表管理的问题。
非分区索引创建方式，create index index_name on table_name(column_name);
查询索引状态从dba_indexes->status列查询
全局分区索引创建，create index index_name on table_name(column_name) global partition by range(column_name) (partition p1 values less than (11104) tablespace system,partition p2 values less than (11100) tablespace users,partition p3 values less than (maxvalue) tablespace sysaux.) or partition by hash (id) partitions 8 online等;
查询索引状态dba_ind_partitions->STATUS列查询
查询分区索引类型，是全局or本地 DBA_PART_INDEXES ->LOCALITY
本地分区索引创建，create index index_name on table_name(column_name) local;
查询索引状态dba_ind_partitions->STATUS列查询
二、create/selet 说明
1) 非分区索引 SQL> create index ind_1 on range_part_tab(deal_date); Index created. SQL> select index_name,PARTITION_NAME,HIGH_VALUE,STATUS,TABLESPACE_NAME from dba_ind_partitions where index_owner=‘SYS‘ and index_name=‘IND_1‘; no rows selected SQL> select index_name,STATUS,GLOBAL_STATS,TABLESPACE_NAME from dba_indexes where owner=‘SYS‘ and index_name=‘IND_1‘; INDEX_NAME STATUS GLO TABLESPACE_NAME ------------------------------ -------- --- ------------------------------ IND_1 VALID YES SYSTEM STATUS 表示一个非分区索引是否VALID或UNUSABLE GLOBAL_STATUS 对于分区索引，指示是通过分析整个索引（YES）来收集统计信息，还是根据基础索引分区和子分区（NO）的统计信息进行估计
2）全局分区索引
create index ind_3 on range_part_tab(area_code) global partition by range(area_code) (partition p1 values less than (11104) tablespace system,partition p2 values less than (11100) tablespace users,partition p3 values less than (maxvalue) tablespace sysaux)
*

hash全局分区索引，使用场景较多，例如索引块争用，且表为非分区表时
SYS@ceshi>create table a1 as select * from range_part_tab;
SYS@ceshi>create index ind_4 on a1(id) global partition by hash (id) partitions 8 online;

三、索引的重建
非分区索引：
SQL> alter index ind_1 rebuild;
全局分区索引：
SQL> alter table range_part_tab move partition p1;
Table altered.
SQL> select TABLE_NAME,PARTITION_NAME,TABLESPACE_NAME from dba_tab_partitions
where TABLE_OWNER=‘SYS‘ and TABLE_NAME=‘RANGE_PART_TAB‘;
TABLE_NAME PARTITION_ TABLESPACE_NAME
------------------------------ ---------- ------------------------------
RANGE_PART_TAB P1 SYSTEM
RANGE_PART_TAB P10 SYSTEM
RANGE_PART_TAB P11 SYSTEM
SQL> select index_name,PARTITION_NAME,HIGH_VALUE,STATUS,TABLESPACE_NAME
from dba_ind_partitions where index_owner=‘SYS‘ and index_name=‘IND_3‘;
INDEX_NAME PARTITION_ HIGH_VALUE STATUS TABLESPACE_NAME
---------- ---------- -------------------- -------- ------------------------------
IND_3 P1 592 USABLE SYSTEM
IND_3 P2 11100 USABLE USERS
IND_3 P3 MAXVALUE USABLE SYSAUX
SQL> alter index ind_3 rebuild partition p1;
Index altered.
全局分区索引，单个分区的move并不会导致全局分区索引的失效
本地分区索引
select index_name,PARTITION_NAME,STATUS,TABLESPACE_NAME
from dba_ind_partitions where index_owner=‘SYS‘ and index_name=‘IND_2‘;
INDEX_NAME PARTITION_ STATUS TABLESPACE_NAME
---------- ---------- -------- ------------------------------
IND_2 P1 USABLE SYSTEM
IND_2 P10 USABLE SYSTEM
IND_2 P11 USABLE SYSTEM
IND_2 P12 USABLE SYSTEM
SQL> alter table range_part_tab move partition p1;
Table altered
SQL> alter index ind_2 rebuild partition p1;
Index altered.
