通过DB_LINK按照分区表抽取数据

DB:11.2.0.3.0
OS:oracle-linux 5.7

建表语句：
create table YOON.YOON_HIS
(
  c_id              NUMBER not null,
  YOON_code      VARCHAR2(30),
  create_time       DATE,
  update_time       DATE not null,
)
partition by range (CREATE_TIME)
(
  partition PART_01 values less than (TO_DATE(' 2012-10-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
    tablespace YOON
    pctfree 10
    initrans 1
    maxtrans 255,
  partition SYS_P29637 values less than (TO_DATE(' 2014-08-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
    tablespace YOON
    pctfree 10
    initrans 1
    maxtrans 255
    storage
    (
      initial 8M
      next 1M
      minextents 1
      maxextents unlimited
    ),
  partition SYS_P30739 values less than (TO_DATE(' 2014-09-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
    tablespace YOON
    pctfree 10
    initrans 1
    maxtrans 255
    storage
    (
      initial 8M
      next 1M

创建DB_LINK，按分区表来抽取数据。（因数据量过大，大约8亿行，直接抽取会报undo回滚段错误）

按照分区抽数方法如下：

insert /*+APPEND*/ into YOON.YOON_HIS   select /*+ parallel（t 8） */ * from YOON.YOON_HIS@cts01  t 
where CREATE_TIME<=(TO_DATE(' 2012-10-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'));
commit;


insert /*+APPEND*/ into YOON.YOON_HIS   select /*+ parallel（t 8） */ * from YOON.YOON_HIS@cts01  t 
where CREATE_TIME>(TO_DATE(' 2012-10-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')) and
CREATE_TIME<=(TO_DATE(' 2014-09-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'));
commit;




insert /*+APPEND*/ into YOON.YOON_HIS   select /*+ parallel（t 8） */ * from YOON.YOON_HIS@cts01  t
