【ggs错误】源端插入一次数据，目标端会插入两次
这两天发现了奇怪的问题，就是源端插入一条数据的时候会导致目标端插入两次，然后导致目标端违反唯一性约束，进程abended。
报错如下：
2013-07-29 12:39:41 WARNING OGG-01154 Oracle GoldenGate Delivery for Oracle, r33ciq1.prm: SQL error 1 mapping EPCIQ.T_TSQY_GOODS_PASS to EPCIQ.T_TSQY_GOODS_PASS OCIError ORA-00001: unique constraint (EPCIQ.PK_T_IDEC2_GOODS_LIST_PASS) violated (status = 1), SQL <INSERT INTO "EPCIQ"."T_TSQY_GOODS_PASS" ("ID","LIST_ID","WAREHOUSE_NO","QUANTITY","QUANTITY_UNIT","NET_WEIGHT","WEIGHT_UNIT","CREATE_TIME","UPDATE_DATE","RESERVED1","RESERVED2","RESERVED3","IDEC_HEAD_>.

为了不影响业务，先没有排查该问题，而是尽快拉起r33ciq1进程，每次都如下操作：
目标端：
- disable主键以及唯一性约束
- 等待数据同步
- 删除相同数据
- enable主键以及唯一性约束
后经过排查，发现是复制进程出了问题：
GGSCI (dbrac) 4> view param P43CIQ1
extract p43ciq1
rmthost 192.168.131.43, mgrport 7809

table CCP.*;
table CIQPARA.*;
table GCC.*;
table IEED.*;
table PMS.*;
table EPCIQ.*;
table UIPEPDECL.*;
table YSBJ.*;
table YSPORTAL.*;
table EPCIQ.*;
该表复制了两次，所以导致出错。
停止相关进程，修改该复制进程，重启进程，问题就解决了。
