1.从源端拷贝表定义语句，在目标端执行，确保两边表定义一致，另外需要增加三个字段（INC_ID--记录序列值，ACP_TIME--记录接受时间，FLAG--记录操作类型）
2.在源端表增加补充日志trandata（因为源端已经有该表的抽取，所以该步骤可以省略）
3.目标端添加replicat进程
add replicat inccert,exttrail ./dirdat/cust11/la,checkpointtable OGGNEW.CHECKPOINT
4.编辑配置
REPLICAT inccert setenv (NLS_LANG="AMERICAN_AMERICA.ZHS16GBK") setenv (ORACLE_SID=xxoo) setenv (ORACLE_HOME=/opt/oracle/product/11.2) userid ogg, password xxoo nohandlecollisions checksequencevalue discardrollover assumetargetdefs applynoopupdates --getupdatebefores reperror default, discard discardfile /dat/dirrpt/rpcert_001.dsc, append, megabytes 1024 eofdelaycsecs 10 batchsql opsperbatch 2000 MAP CRM20.tb_pty_certif_id_var_info, TARGET test.INC_VAR_INFO,& INSERTALLRECORDS,& SQLEXEC (id tb_pty_certif_id_var_info, query "select test.SEQ_INC_INFO.nextval id from dual",noparams,ERROR RAISE),& SQLEXEC (id tb_pty_certif_id_var_infot,query "select sysdate id from dual",noparams,ERROR RAISE),& colmap ( FLAG[email protected] (@GETENV("GGHEADER","OPTYPE"), "UPDATE", "M", "ENSCRIBE COMPUPDATE", "M", "SQL COMPUPDATE", "M", "PK UPDATE", "M", "DELETE", "D", "INSERT", "A", "TRUN CATE", "T"),& INC_ID=tb_pty_certif_id_var_info.id,& ACP_TIME=tb_pty_certif_id_var_infot.id,& IDENTITY=IDENTITY,& GENDER=GENDER,& BIRTHDAY=BIRTHDAY,& NATIONALITY=NATIONALITY,& ADDRESS=ADDRESS,& SIGN_UNIT=SIGN_UNIT,& DEGREE=DEGREE,& CAREER=CAREER,& ADDR_CD=ADDR_CD,& ADDRESS_COUNT=ADDRESS_COUNT,& LATN_ID=LATN_ID,& NAME=NAME,& CRT_DATE=CRT_DATE,& PHOTO=PHOTO,& DATA_SOURCE=DATA_SOURCE,& CERT_ORG=CERT_ORG,& EFF_DATE=EFF_DATE,& EXP_DATE=EXP_DATE );
5.目标端表添加自增序列
create sequence crm40.SEQ_INC_INFO minvalue 1 maxvalue 9999999999999999999999999999 start with 1 increment by 1 cache 2000;
6.起复制进行
alter REPLICAT inccert,begin now
启动后就append了，报错如下
ERROR OGG-01163 Bad column length (8) specified for column GENDER in table test.INC_VAR_INFO, maximum allowable length is 5.
检查两边表的定义确实都是一致的，所以出现这个问题比较奇怪
解决思路：
在源端生成表的定义，并传送到目标端
$vi source.prm
defsfile ./dirdef/certif.def,purge userid ogg, PASSWORD xxoo table username.tablename;
$defgen paramfile source.prm
在目标端的配置文件中修改相应参数
--assumetargetdefs sourcedefs ./dirdef/certif.def
重启复制进程后恢复正常
