怎么進行ogg配置

本篇文章給大家分享的是有關怎么進行ogg配置，小編覺得挺實用的，因此分享給大家學習，希望大家閱讀完這篇文章后可以有所收獲，話不多說，跟著小編一起來看看吧。

Ogg配置

源庫端 首先要是歸檔模式, 要開啟數據庫最小附加日志模式,和所需同步表的補全日志

命令如下

Sql > select supplemental_log_data_min from v$database;

      --顯示為no 表示未開啟

Sql> alter database add supplemental log data;

      --開啟數據庫級別的最小附加日志模式

Sql >select force_logging from v$database;

      --查看是否開啟了強制日志模式,以免丟失數據

Sql> Alter database force logging;

      --開啟日志強制模式

Sql> alter table <tablename> add supplemental log data (primary key) columns;

節點一：

alter database force logging;

alter database add supplemental log data;

alter table scott.t1 add supplemental log data (primary key) columns;

節點2：

alter database force logging;

alter database add supplemental log data;

alter table scott.t2 add supplemental log data (primary key) columns;

alter table scott.t3 add supplemental log data (primary key) columns;

create directory dp_dir as '/home/oracle/expdp/';

創建goldengate用戶并賦予權限：

create  user goldengate identified by goldengate;

grant connect,resource  to goldengate;

grant delete any table to goldengate;

grant update any table to goldengate;

grant insert any table to goldengate;

grant select any table to goldengate;

grant SELECT ANY DICTIONARY to goldengate;

--開啟基于檢查點的復制

Ggsic>dblogin userid goldengate,password goldengate

edit  param ./GLOBALS

checkpointtable goldengate.checkpoint

 然后保存退出,

add checkpointtable goldengate.checkpoint

ogg：

主進程配置

edit param mgr

PORT 7801

DYNAMICPORTLIST 7802-7820

Purgeoldextracts /home/oracle/ogg/dirdat/*/* USECHECKPOINTS,MINKEEPHOURS 10

AUTORESTART  EXTRACT *,WAITMINUTES 2,RETRIES 5

節點一：

新增抽取進程：

edit param ext-t1

extract  ext-t1

userid goldengate,password goldengate

exttrail    /home/oracle/ogg/dirdat/scott/es

dynamicresolution

WARNLONGTRANS 1h,CHECKINTERVAL 3m   

table  scott.t1;

添加進程

add extract ext-t1,tranlog,begin now

添加本地隊列

add exttrail /home/oracle/ogg/dirdat/scott/es,extract ext-t1, megabytes 1000

新增投遞進程：

edit param pp-t1

extract      pp-t1

userid  goldengate ,password goldengate

RMTHOST      172.18.0.139, MGRPORT 7801,COMPRESS

rmttrail         /home/oracle/ogg/dirdat/scott/t1

dynamicresolution

table  scott.t1;

添加進程

add extract pp-t1,exttrailsource /home/oracle/ogg/dirdat/scott/es ,begin now

--添加遠端隊列

add  rmttrail  /home/oracle/ogg/dirdat/scott/t1, extract pp-t1,megabytes 1000

節點二：

新增抽取進程：

edit param ext-t2

extract  ext-t2

userid goldengate,password goldengate

exttrail    /home/oracle/ogg/dirdat/scott/es

dynamicresolution

WARNLONGTRANS 1h,CHECKINTERVAL 3m   

table  scott.t2;

table  scott.t3;

添加進程

add extract ext-t2,tranlog,begin now

添加本地隊列

add exttrail /home/oracle/ogg/dirdat/scott/es,extract ext-t2, megabytes 1000

新增投遞進程：

edit param pp-t2

extract      pp-t2

userid  goldengate ,password goldengate

RMTHOST      172.18.0.139, MGRPORT 7801,COMPRESS

rmttrail         /home/oracle/ogg/dirdat/scott/t2

dynamicresolution

table  scott.t2;

table  scott.t3;

添加進程

add extract pp-t2,exttrailsource /home/oracle/ogg/dirdat/scott/es ,begin now

--添加遠端隊列

add  rmttrail  /home/oracle/ogg/dirdat/scott/t2, extract pp-t2,megabytes 1000

目標端：

新增復制進程1：

edit param rp-t1

replicat   rp-t1

userid goldengate,password goldengate

assumetargetdefs

HANDLECOLLISIONS

reperror default,discard

discardfile /home/oracle/ogg/dirdat/scott/t1.dsc,append,megabytes 1000

map  scott.t1, target scott.t1;

新增復制進程：

add replicat  rp-t1,exttrail /home/oracle/ogg/dirdat/scott/t1,begin now,checkpointtable goldengate.checkpoint

新增復制進程2：

edit param rp-t2

replicat   rp-t2

userid goldengate,password goldengate

assumetargetdefs

HANDLECOLLISIONS

reperror default,discard

discardfile /home/oracle/ogg/dirdat/scott/t2.dsc,append,megabytes 1000

map  scott.t2, target scott.t2;

map  scott.t3, target scott.t3;

新增復制進程：

add replicat  rp-t2,exttrail /home/oracle/ogg/dirdat/tbs01/t2,begin now,checkpointtable goldengate.checkpoint

創建測試表：

create table scott.t1 as select * from scott.emp;

alter table scott.t1 add constraint t1_pk primary key(empno)

create table scott.t2 as select * from scott.emp;

alter table scott.t2 add constraint t2_pk primary key(empno);

create table scott.t3 as select * from scott.emp;

alter table scott.t3 add constraint t3_pk primary key(empno);

目標庫建立相應表結構：

create table scott.t1 as select * from scott.emp where 1=2;

alter table scott.t1 add constraint t1_pk primary key(empno)

create table scott.t2 as select * from scott.emp where 1=2;

alter table scott.t2 add constraint t2_pk primary key(empno);

create table scott.t3 as select * from scott.emp where 1=2;

alter table scott.t3 add constraint t3_pk primary key(empno);

expdp/impdp導出導入測試表數據。

啟動進程：

1、  分別在各個源端和目標端啟動start mgr

2、  啟動各個源端抽取和投遞進程

3、  數據導入目標端后，啟動目標端復制進程

4、  使用info all查看各個進程狀態，正常為running

5、  若出錯，使用view report + 進程名查看報錯并解決之。

測試：在源端表進行dml操作，觀察目標端相應表數據變化。若兩端一致，則ogg搭建成功
