数据库版本 11.2.0.3.0
使用impdp + network_link 功能不落地同步数据表。
已知：
源库 dw.dw_c_d_user_all:P_201407 和 dw.dw_c_d_user_all:P_201408 实际均有数据。
SQL> SELECT COUNT(*) FROM DW.DW_C_D_USER_ALL PARTITION(P_201407) UNION ALL SELECT COUNT(*) FROM DW.DW_C_D_USER_ALL PARTITION(P_201408);
COUNT(*)
----------
271697
307026
使用impdp user/********tables=dw.dw_c_d_user_all:P_201407 network_link=boncbi_145 table_exists_action=TRUNCATE CONTENT=DATA_ONLY
impdpuser/********tables=dw.dw_c_d_user_all:P_201408 network_link=boncbi_145 table_exists_action=TRUNCATE CONTENT=DATA_ONLY
201407 无法同步数据， 但201408可以。
类似的表还有很多，不解
源库 DW.DW_C_D_USER_ALL 已经执行表分析
CALL DBMS_STATS.GATHER_TABLE_STATS('DW','DW_C_D_USER_ALL','P_201407');
CALL DBMS_STATS.GATHER_TABLE_STATS('DW','DW_C_D_USER_ALL','P_201408');
目的库是否已经建表，对执行结果无影响。
请各位老师帮忙解答。 谢谢。
