1.因为工作需要，需要将CAMS_CORE用户下的表做一次表空间迁移，生成迁移命令脚本如下：
select 'alter table CAMS_CORE.'|| TABLE_NAME || ' move tablespace cams_core_tab;' from dba_tables where owner='CAMS_CORE';
2.将生成的语句进行迁移，其中有2个表为Interval Partition分区表，迁移时遇到了问题：
alter table CAMS_CORE.BP_VOUCHER_RECENT move tablespace cams_core_tab; alter table CAMS_CORE.BP_VOUCHER_HISTORY move tablespace cams_core_tab;
提示错误
ORA-14511: cannot perform operation on a partitioned object
3.使用oerr查看错误信息
[oracle@XLJ181 dump]$ oerr ORA 14511 14511, 00000, "cannot perform operation on a partitioned object" // *Cause: An attempt was made to perform an operation that is not allowed // on partitioned tables or indexes. // *Action: Retry the command with correct syntax.
4.从错误提示上看，应该是分区表的迁移不能基于表迁移，需要基于分区进行迁移，特此改进操作，先查看dba_tab_partitions表的字段
SYS@cams> desc dba_tab_partitions Name Null? Type ----------------------------------------- -------- ---------------------------- TABLE_OWNER VARCHAR2(30) TABLE_NAME VARCHAR2(30) COMPOSITE VARCHAR2(3) PARTITION_NAME VARCHAR2(30) SUBPARTITION_COUNT NUMBER HIGH_VALUE LONG HIGH_VALUE_LENGTH NUMBER PARTITION_POSITION NUMBER TABLESPACE_NAME VARCHAR2(30) PCT_FREE NUMBER PCT_USED NUMBER INI_TRANS NUMBER MAX_TRANS NUMBER INITIAL_EXTENT NUMBER NEXT_EXTENT NUMBER MIN_EXTENT NUMBER MAX_EXTENT NUMBER MAX_SIZE NUMBER PCT_INCREASE NUMBER FREELISTS NUMBER FREELIST_GROUPS NUMBER LOGGING VARCHAR2(7) COMPRESSION VARCHAR2(8) COMPRESS_FOR VARCHAR2(12) NUM_ROWS NUMBER BLOCKS NUMBER EMPTY_BLOCKS NUMBER AVG_SPACE NUMBER CHAIN_CNT NUMBER AVG_ROW_LEN NUMBER SAMPLE_SIZE NUMBER LAST_ANALYZED DATE BUFFER_POOL VARCHAR2(7) FLASH_CACHE VARCHAR2(7) CELL_FLASH_CACHE VARCHAR2(7) GLOBAL_STATS VARCHAR2(3) USER_STATS VARCHAR2(3) IS_NESTED VARCHAR2(3) PARENT_TABLE_PARTITION VARCHAR2(30) INTERVAL VARCHAR2(3) SEGMENT_CREATED VARCHAR2(4)
5.拼写自动生成迁移语句的sql
SYS@cams> set pages 1000
SYS@cams> set lines 200
SYS@cams> select 'alter table ' ||table_owner|| '.' || table_name || ' move partition ' || partition_name || ' tablespace cams_core_tab;' as move_sql from dba_tab_partitions where table_owner='CAMS_CORE' and table_name in ('BP_VOUCHER_RECENT','BP_VOUCHER_HISTORY');
MOVE_SQL
-------------------------------------------------------------------------------------------------------------------------------------------------
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition P0 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition P1 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition P2 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P118 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P119 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P120 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P121 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P122 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P123 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P124 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P125 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P126 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P127 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P128 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P129 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P130 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P131 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P132 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P133 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_HISTORY move partition SYS_P134 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_RECENT move partition P0 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_RECENT move partition P1 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_RECENT move partition P2 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_RECENT move partition P3 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_RECENT move partition P4 tablespace cams_core_tab;
alter table CAMS_CORE.BP_VOUCHER_RECENT move partition P5 tablespace cams_core_tab;
26 rows selected.6.将生成的sql重新执行，全部提示成功，表空间迁移顺利完成。
