OBJECT_ID与DATA_OBJECT_ID不一致，造成impdp导入[0 rows]
今天开发组的DBLINK环境发生一个奇怪的现象，一个分区表通过DBLINK进行数据插入时，
原表的近万条数据没有被插入就正常结束了。导入的结果是[0 rows] 正常结束。
在MOS上查了一下，这个现象，找到了下面的文档
DataPump Expdp Or Impdp With NETWORK_LINK Returns No Rows Exported Or
Imported For Partitioned Table (Doc ID 1381419.1)
按文档的说明，在Oracle11.2.0.1环境中，通过DBLINK实现impdp(expdp)时，由于
OBJECT_ID与DATA_OBJECT_ID不一致，造成这个分区的数据无法正常导出（导入）。
解决方法就是升级到11.2.0.2。
为此，我做如下的实验
--在主表侧做一个实现用的表
SQL> create table test_tab
(
deptno number,
deptname varchar2(20),
quarterly_sales number(10, 2),
state varchar2(2)
)
partition by list (state)
(
partition northwest values ('OR', 'WA'),
partition southwest values ('AZ', 'UT', 'NM'),
partition northeast values ('NY', 'VM', 'NJ'),
partition southeast values ('FL', 'GA'),
partition northcentral values ('SD', 'WI'),
partition southcentral values ('OK', 'TX')
); 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
表が作成されました。
