目的端配置大致分为如下三个步骤：配置mgr,配置checkpoint table,配置应用进程
在目的端先创建一张表,记得带主键：
create database hr;Query OK, 1 row affected (0.00 sec)
①配置mgr
GGSCI (nosql2) 2> edit params mgr PORT 7809 DYNAMICPORTLIST 7810-7909 --AUTOSTART ER * AUTORESTART EXTRACT *,RETRIES 5,WAITMINUTES 3 PURGEOLDEXTRACTS ./dirdat/*,usecheckpoints, minkeepdays 3 LAGREPORTHOURS 1 LAGINFOMINUTES 30 LAGCRITICALMINUTES 45 GGSCI (nosql2) 3> start mgr Manager started. GGSCI (nosql2) 4> info all Program Status Group Lag at Chkpt Time Since Chkpt MANAGER RUNNING
GGSCI (nosql2) 7> edit params ./GLOBALS
CHECKPOINTTABLE hr.checkpoint
添加：
GGSCI (nosql2) 8> add checkpointtable hr.checkpointtab Successfully created checkpoint table hr.checkpointtab. GGSCI (nosql2) 9> info checkpointtable hr.checkpointtab Checkpoint table hr.checkpointtab created 2014-04-02 16:11:38. GGSCI (nosql2) 10> 在相应的mysql数据库中,也可以看到相应的表被添加了： mysql> show tables; +---------------+ | Tables_in_hr | +---------------+ | ah4 | | checkpointtab | +---------------+ 2 rows in set (0.00 sec)
GGSCI (nosql2) 10> edit params rep3 replicat rep3 sourcedefs /u01/ogg/11.2/dirdef/ah④prm SOURCEDB hr,userid root,password 123456 reperror default,discard discardfile /u01/ogg/11.2/dirrpt/rep④dsc,append,megabytes 50 map hr.ah4, target hr.ah4;
GGSCI (nosql2) 13> add replicat rep3,exttrail /u01/ogg/11.2/dirdat/xs,checkpointtable hr.checkpointtab
REPLICAT added.
PS:
REPLICAT进程参数配置说明：ASSUMETARGETDEFS：假定两端数据结构一致使用此参数；SOURCEDEFS：假定两端数据结构不一致,使用此参数指定源端的数据结构定义文件,该文件需要由GlodenGate工具产生.MAP:用于指定源端与目标端表的映射关系；MAPEXCLUDE：用于使用在MAP中使用*匹配时排除掉指定的表；REPERROR：定义出错以后进程的响应,一般可以定义为两种：ABEND,即一旦出现错误即停止复制,此为缺省配置；DISCARD,出现错误后继续复制,只是把错误的数据放到discard文件中.DISCARDFILE：定义discardfile文件位置,如果处理中油记录出错会写入到此文件中；SQLEXEC：在进程运行时首先运行一个SQL语句；GROUPTRANSOPS：将小交易合并成一个大的交易进行提交,减少提交次数,降低系统IO消耗.MAXTRANSOPS：将大交易拆分,每XX条记录提交一次.
源端进程：

源端插入数据：
SQL> insert into ah4 values(1,'aaaccc'); 1 row created. SQL> commit; Commit complete.
