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
