ORACLE源库配置准备工作：

1）开启附加日志

selectsupplemental_log_data_minfromv$database;SUPPLEME---------------NOalterdatabaseaddsupplementallogdata;selectsupplemental_log_data_minfromv$database;SUPPLEME---------------YES

2）开启归档（已经是归档模式，省略）

SQL>shutdownimmediateSQL>startupmountSQL>alterdatabasearchivelog;SQL>archiveloglist;DatabaselogmodeArchiveModeAutomaticarchivalEnabledArchivedestination/u01/archSQL>alterdatabaseopen;

3）创建OGG同步用户：

createusergoldengateidentifiedbygoldengatedefaulttablespaceusers;grantdbatogoldengate;

源库操作（oracle端）：

1源端删除抽取，传输进程：

dbloginuseridgoldengate,passwordgoldengate

--增加待同步表的附加日志：

addtrandataMW_APP.DYT_DATALOSTRECORD

创建抽取进程相关GGLOG日志目录：

mkdir–p/ogg/gglog/e_MW_APP/

增加新的抽取进程：

addextracte_MW_APP,tranlog,beginnowaddexttrail/ogg/gglog/e_MW_APP/ex,extracte_MW_APP,megabytes200

2,删除并增加传输进程：

addextractp_MW_APP,exttrailsource/ogg/gglog/e_MW_APP/exaddrmttrail/ogg/gglog/MW_APP/re,extractp_MW_APP,megabytes200

3在源端启动抽取进程前，先做以下操作：

alterextractp_MW_APP,beginnow--让传输进程从此刻开始启动传输数据starte_MW_APP

创建要同步的表的定义（重要）

1.#创建参数文件

GGSCI(pos300-db01)10>editparamdefgendefsfile./dirdef/MW_APP.defuseridgoldengate,passwordgoldengatetableMW_APP.*;#生成表定义文件./defgenparamfile./dirprm/defgen.prm#传至目标库目录scp/ogg/software/dirdef/MW_APP.defroot@192.168.1.241:/ogg/software/dirprm

目标库（MYSQL端）

4删除复制进程和检查点表：

目标库为Mysql， 同oracle与oracle之间的同步略有区别

1）创建用户和待同步库

mysql>GRANTALLPRIVILEGESON`MW_APP`.*TOroot@'%'IDENTIFIEDBY‘root’;mysql>createdatabaseMW_APP;

2）创建目录

GGSCI(zoop300)1>createsubdirsCreatingsubdirectoriesundercurrentdirectory/home/mysqlParameterfiles/goldengate/dirprm:createdReportfiles/goldengate/dirrpt:createdCheckpointfiles/goldengate/dirchk:createdProcessstatusfiles/goldengate/dirpcs:createdSQLscriptfiles/goldengate/dirsql:createdDatabasedefinitionsfiles/goldengate/dirdef:createdExtractdatafiles/goldengate/dirdat:createdTemporaryfiles/goldengate/dirtmp:createdStdoutfiles/goldengate/dirout:createdmkdir–p/ogg/gglog/MW_APP/

3）配置管理进程

GGSCI(zoop300)3>editparamsmgr加入：port7809GGSCI(zoop300)4>startmgrManagerstarted.GGSCI(zoop300)3>infomgrManagerisrunning

4）配置检查点及全局

GGSCI(zoop300)4>dbloginsourcedbMW_APPuseridrootpasswordrootGGSCI(zoop300)5>addcheckpointtableMW_APP.checkpoint_tableGGSCI(zoop300)6>editparams./GLOBALScheckpointtableMW_APP.checkpoint_table

5）配置replicat进程

GGSCI(zoop300)8>addreplicatr_MW_APP,exttrail/ogg/gglog/MW_APP/re,checkpointtableMW_APP.checkpoint_table

编辑replicat进程

editparamsr_MW_APP

--加入下列参数

replicatr_MW_APPtargetdbMW_APPuseridrootpasswordroothandlecollisionssourcedefs/ogg/software/dirprm/MW_APP.defdiscardfile/ogg/software/dirrpt/dcr1.dsc,purgemapMW_APP.DYT_DATALOSTRECORD,targetMW_APP.DYT_DATALOSTRECORD;

启动进程：

GGSCI(zoop300)9>startdcr1

4、测试数据同步
