源库配置

数据库设置为归档模式

ALTER DATASBASE ARCHIVELOG;

开启强制日志

ALTER DATABASE FORCE LOGGING;

开启附加日志

ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;

修改参数

ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION=TRUE;

创建用户

--创建用户表空间
create tablespace ogg datafile '/u01/app/oracle/oradata/ogg.dbf' size 2G autoextend off;
--创建用户
create user ogg identified by ogg default tablespace ogg;
--添加权限
grant connect,resource,create session,alter session,select any dictionary,select any table,flashback any table,alter any table,insert any table,update any table,delete any table,select any transaction,execute on DBMS_CAPTURE_ADM to ogg;

解压安装

配置MGR进程

GGSCI>edit params mgr
port 7809
DYNAMICPORTLIST 7840-7850
PURGEOLDEXTRACTS /u01/ogg/testogg/dirdat/*,usecheckpoints,minkeepdays 7

创建defgen文件

a.编辑defgen参数
GGSCI> edit params defgen
defsfile /u01/ogg/dirdef/sync.def
userid ogg,password ogg?123
table DC_DC.DC_RA_MER_BASE; 
b.生成defgen文件
./defgen paramfile /oraogg/app/dirprm/defgen.prm
c.将sync.def复制到目标端dirdef目录下

添加表附加日志

GGSCI>add trandata DC_DC.DC_RA_MER_BASE; 

配置抽取进程

a.创建trail文件目录
mkdir -p /u01/ogg/dirdat/EXMSSQL

b.添加抽取进程
GGSCI>add extract extest01,tranlog,threads 1,begin now
GGSCI>add exttrail /u01/ogg/dirdat/EXMSSQL/EX,extract extest01,megabytes 200
GGSCI>edit param extest01
extract extest01

目标库配置

配置ODBC接口

创建服务

>INSTALL ADDSERVICE 

编辑GLOBALS

GGSCI >edit param ./GLOBALS
checkpointtable dbo.ckpttab

创建checkpoint表

GGSCI >dblogin lu userid sa password abcd123#
GGSCI >add checkpointtable dbo.ckpttab

配置MGR进程

GGSCI >edit params mgr

DYNAMICPORTLIST 7840-7850
ACCESSRULE, PROG SERVER, ALLOW
autorestart er *, retries 5, waitminutes 3
purgeoldextracts F:\OGG\dirdat\*,usecheckpoints, minkeepdays 7

配置复制进程

a. 创建trail存放目录
F:\ogg\dirdat\REMSSQL
b.添加复制进程
GGSCI >add replicat REMSSQL,exttrail F:\OGG\dirdat\REMSSQL\RE,begin now,checkpointtable dbo.ckpttab
GGSCI >edit param REMSSQL
replicat REMSSQL
sourcedefs F:\OGG\dirdef\sync.def

discardfile F:\OGG\dirrpt\REMSSQL.dsc,append,megabytes 100
gettruncates
map DC_DC.DC_RA_MER_BASE,target dbo.DC_RA_MER_BASE;

初始化数据

a.在SQLSERVER创建相应表
b.源端导出相应表初始化数据
GGSCI> edit param exinit
SOURCEISTABLE
userid ogg, password ogg?123
rmthost 182.168.8.1, mgrport 7809
RMTFILE F:\OGG\dirdat\REMSSQL\EX,MAXFILES 1024, MEGABYTES 1024
table test.dc_ra_mer_base;

--OGG INSTALL DIRECTORY
$ ./extract paramfile ./dirprm/exinit.prm reportfile ./dirrpt/exinit.rpt
c.启动源端进程
GGSCI>start *
d.目标段导入相应初始化数据并启动进程
replicat paramfile ./dirprm/reinit.prm
GGSCI>start *
