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
相关的rpm文件发我,8chf@163.com
在centos上,报下面的错误(mysql的binlog已经开启,format设为row):
