异常处理一（异常表通用型）
新建异常处理表

create table ogg.exception_log
    ( replicat_name varchar2(10),
      table_name varchar2(100),
      errno number,
      dberrmsg varchar2(4000),
      optype varchar2(20),
      errtype varchar2(20),
      logrba number,
      logposition number,
     committimestamp timestamp,
     primary key(logrba,logposition,committimestamp)
);

REPLICAT添加异常处理

REPERROR (DEFAULT, EXCEPTION)
REPERROR (DEFAULT2,discard)---abend根据需求
map chf.a_t_1, target chf.a_t_1;
map chf.a_t_1, target ogg.exception_log,
EXCEPTIONSONLY,
INSERTALLRECORDS,
COLMAP (   replicat_name = "repl"
, table_name = @GETENV ("GGHEADER", "TABLENAME")
, errno = @GETENV ("LASTERR", "DBERRNUM")
, dberrmsg = @GETENV ("LASTERR", "DBERRMSG")
, optype = @GETENV ("LASTERR", "OPTYPE")
, errtype = @GETENV ("LASTERR", "ERRTYPE")
, logrba = @GETENV ("GGHEADER", "LOGRBA")
, logposition = @GETENV ("GGHEADER", "LOGPOSITION")
, committimestamp = @GETENV ("GGHEADER", "COMMITTIMESTAMP"));
--实例中只处理chf.a_t_1表

异常处理二(异常表需要定制)
新建表(正常表和异常表)

--正常表
create table fei_1_1(id number , name varchar2(1000));
--异常表
create table ogg.exception_fei_1
    ( id number,
      name varchar2(1000),
      table_name varchar2(100),
      errno number,
      dberrmsg varchar2(4000),
      optype varchar2(20),
      errtype varchar2(20),
      logrba number,
      logposition number,
     committimestamp timestamp,
     primary key(logrba,logposition,committimestamp)
);

异常处理程序

map chf.fei_1, target chf.fei_1_1;
map chf.fei_1, target ogg.exception_fei_1,
EXCEPTIONSONLY,
INSERTALLRECORDS,
COLMAP ( USEDEFAULTS
, table_name = @GETENV ("GGHEADER", "TABLENAME")
, errno = @GETENV ("LASTERR", "DBERRNUM")
, dberrmsg = @GETENV ("LASTERR", "DBERRMSG")
, optype = @GETENV ("LASTERR", "OPTYPE")
, errtype = @GETENV ("LASTERR", "ERRTYPE")
, logrba = @GETENV ("GGHEADER", "LOGRBA")
, logposition = @GETENV ("GGHEADER", "LOGPOSITION")
, committimestamp = @GETENV ("GGHEADER", "COMMITTIMESTAMP"));

异常处理三（通配符MAPEXCEPTION）
新建异常表

create table ogg.exception_fei_all
    ( replicat_name varchar2(10),
      table_name varchar2(100),
      errno number,
      dberrmsg varchar2(4000),
      optype varchar2(20),
      errtype varchar2(20),
      logrba number,
      logposition number,
     committimestamp timestamp,
     primary key(logrba,logposition,committimestamp)
);

异常处理程序

MAP chf.fei_*, TARGET chf.*,
MAPEXCEPTION (TARGET ogg.exception_fei_all,
COLMAP (   replicat_name = "repl"
, table_name = @GETENV ("GGHEADER", "TABLENAME")
, errno = @GETENV ("LASTERR", "DBERRNUM")
, dberrmsg = @GETENV ("LASTERR", "DBERRMSG")
, optype = @GETENV ("LASTERR", "OPTYPE")
, errtype = @GETENV ("LASTERR", "ERRTYPE")
, logrba = @GETENV ("GGHEADER", "LOGRBA")
, logposition = @GETENV ("GGHEADER", "LOGPOSITION")
, committimestamp = @GETENV ("GGHEADER", "COMMITTIMESTAMP")));

处理说明：
REPERROR参数用以控制Replicat进程如何响应映射过程中发生的错误
DEFAULT参数代表一种全局错误类型，即除去所有已明确指定的错误外的一切错误
DEFAULT2参数代表当DEFAULT错误以Exception方式响应时，所有MAP映射中未定义Exception部分出现的所有错误
EXCEPTIONSONLY只能用于确定表的异常处理
MAPEXCEPTION可以用于通配符的表异常处理

一、source端

add extract extl,tranlog,begin now
ADD EXTTRAIL /u01/ogg/dirdat/lr, EXTRACT EXTL
ADD TRANDATA chf.objce_t

edit params extl
extract extl
userid ogg,password xifenfei
exttrail /u01/ogg/dirdat/lr
dynamicresolution
gettruncates
table chf.objce_t;

ADD EXTRACT pump1, EXTTRAILSOURCE /u01/ogg/dirdat/lr, BEGIN now
add rmttrail /u01/ogg/dirdat/rl extract pump1

edit params pump1
extract pump1
userid ogg, password xifenfei

rmttrail /u01/ogg/dirdat/rl
PASSTHRU
gettruncates
table chf.objce_t;

二、target端

edit params ./GLOBALS
CHECKPOINTTABLE ogg.chkpoint

dblogin userid ogg,password xifenfei
ADD CHECKPOINTTABLE ogg.chkpoint

add replicat repl exttrail /u01/ogg/dirdat/rl,begin now,checkpointtable ogg.chkpoint 

edit  params repl
replicat repl                               
userid ogg,password xifenfei                    
assumetargetdefs                          
reperror default,discard

gettruncates                                                      
map chf.objce_t, target chf.objce_t;   

一、source端

add extract extl,vam,begin now
ADD EXTTRAIL F:\ogg\mysql\dirdat\rl, EXTRACT EXTL

edit params extl
extract extl
sourcedb test@localhost:3306,userid root,password xifenfei
exttrail F:\ogg\mysql\dirdat\rl
dynamicresolution
gettruncates
table test.t_1;

add EXTRACT pump1, EXTTRAILSOURCE F:\ogg\mysql\dirdat\rl, BEGIN now
add rmttrail /ogg/mysql/dirdat/rl extract pump1

edit params pump1
extract pump1
rmthost 192.168.1.111,mgrport 7808
rmttrail /ogg/mysql/dirdat/rl
PASSTHRU
gettruncates
table test.t_1;

二、target端

edit params ./GLOBALS
dblogin sourcedb test@localhost:3306,userid root,password xifenfei
CHECKPOINTTABLE ogg.chkpoint

ADD CHECKPOINTTABLE ogg.chkpoint

add replicat repl exttrail /ogg/mysql/dirdat/rl,begin now,checkpointtable ogg.chkpoint 

edit params repl
replicat repl
DBOPTIONS HOST 127.0.0.1, CONNECTIONPORT 3306
TARGETDB test,userid root,password xifenfei
assumetargetdefs
reperror default,discard
discardfile /tmp/mysql.dsc,append,megabytes 100
gettruncates
map TEST.T_1, target "test.t_1";     

三、说明
本实例是win 中的mysql同步到linux中的mysql
有个注意点：
1、add extract extl,vam,begin now 不像oracle中的tranlog
2、注意各个参数中schema.tablename大小写问题
1）win中不区分，全部使用小写会自动转换为大写
2）在replicate参数中，因为map是从win中的data pump中得到，所以map后面的schema.tablename需要大写
3）在replicate参数中，因为table是linux中的对应linux中的数据库名和表名（mysql是以文件形式存储，一般均为小写），所以map后面的schema.tablename需要小写+双引号，防止转为大写
3、注意mysql数据库编码
四、与oracle不同之处
1、登录
dblogin sourcedb dbname@localhost:3306,userid root,password xifenfei

2、Extract中访问mysql
sourcedb dbname@localhost:3306,userid root,password xifenfei

3、Replicat中访问mysql
DBOPTIONS HOST 127.0.0.1, CONNECTIONPORT 3306
TARGETDB dbname,userid root,password xifenfei
