move分区表

原创 Linux操作系统 作者:myownstars 时间:2011-10-19 17:42:25 0 删除 编辑

现在需要将一些分区表移到别的表空间下去,且该表是arc表,目前是没有任何程序访问,不需使用在线重定义,可以直接move.
SQL> alter table JUSTIN move tablespace ARC;
alter table JUSTIN move tablespace ARC
            *
ERROR at line 1:
ORA-14511: cannot perform. operation on a partitioned object

分区表必须以分区为单位进行move,可以使用以下sql

Elapsed: 00:00:00.00
SQL> select 'alter table '||table_name||' move partition '||partition_name||' tablespace ARC;' from user_tab_partitions where table_name ='JUSTIN';

'ALTERTABLE'||TABLE_NAME||'MOVEPARTITION'||PARTITION_NAME||'TABLESPACEARC
--------------------------------------------------------------------------------
alter table JUSTIN move partition P0912 tablespace ARC;
alter table JUSTIN move partition P1003 tablespace ARC;
alter table JUSTIN move partition P1006 tablespace ARC;
alter table JUSTIN move partition P1009 tablespace ARC;
alter table JUSTIN move partition P1012 tablespace ARC;
alter table JUSTIN move partition P1103 tablespace ARC;
alter table JUSTIN move partition P1106 tablespace ARC;
alter table JUSTIN move partition P1109 tablespace ARC;
alter table JUSTIN move partition P1112 tablespace ARC;
alter table JUSTIN move partition P1203 tablespace ARC;
alter table JUSTIN move partition P1206 tablespace ARC;

11 rows selected.

SQL> alter table JUSTIN move partition P0912 tablespace ARC;
alter table JUSTIN move partition P1003 tablespace ARC;
alter table JUSTIN move partition P1006 tablespace ARC;
alter table JUSTIN move partition P1009 tablespace ARC;
alter table JUSTIN move partition P1012 tablespace ARC;
alter table JUSTIN move partition P1103 tablespace ARC;
alter table JUSTIN move partition P1106 tablespace ARC;
alter table JUSTIN move partition P1109 tablespace ARC;
alter table JUSTIN move partition P1112 tablespace ARC;
alter table JUSTIN move partition P1203 tablespace ARC;
alter table JUSTIN move partition P1206 tablespace ARC;

Table altered.

接下来需要重建索引,分区表上的索引分为分区索引和全局索引,需要区别开来进行重建
重建分区索引
SQL> select 'alter index '||index_name||' rebuild partition '||partition_name||' online tablespace  ARC;' from user_ind_partitions where index_name in (
  2  select index_name from user_indexes where table_name ='JUSTIN')  status != 'USABLE';

no rows selected
重建全局索引
SQL> select 'alter index '||index_name||' rebuild online tablespace  ARC;' from user_indexes where table_name ='JUSTIN'
  2  and status != 'USABLE';

no rows selected
不过这个arch表没有索引,那就不需要重建了,move完成。
