本篇文章给大家分享的是有关怎么进行ogg配置,小编觉得挺实用的,因此分享给大家学习,希望大家阅读完这篇文章后可以有所收获,话不多说,跟着小编一起来看看吧。
Ogg配置
源库端 首先要是归档模式, 要开启数据库最小附加日志模式,和所需同步表的补全日志
命令如下
Sql > select supplemental_log_data_min from v$database;
--显示为no 表示未开启
Sql> alter database add supplemental log data;
--开启数据库级别的最小附加日志模式
Sql >select force_logging from v$database;
--查看是否开启了强制日志模式,以免丢失数据
Sql> Alter database force logging;
--开启日志强制模式
Sql> alter table <tablename> add supplemental log data (primary key) columns;
节点一:
alter database force logging;
alter database add supplemental log data;
alter table scott.t1 add supplemental log data (primary key) columns;
节点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/';
创建goldengate用户并赋予权限:
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;
--开启基于检查点的复制
Ggsic>dblogin userid goldengate,password goldengate
edit param ./GLOBALS
checkpointtable goldengate.checkpoint
然后保存退出,
add checkpointtable goldengate.checkpoint
ogg:
主进程配置
edit param mgr
PORT 7801
DYNAMICPORTLIST 7802-7820
Purgeoldextracts /home/oracle/ogg/dirdat/*/* USECHECKPOINTS,MINKEEPHOURS 10
AUTORESTART EXTRACT *,WAITMINUTES 2,RETRIES 5
节点一:
新增抽取进程:
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;
添加进程
add extract ext-t1,tranlog,begin now
添加本地队列
add exttrail /home/oracle/ogg/dirdat/scott/es,extract ext-t1, megabytes 1000
新增投递进程:
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;
添加进程
add extract pp-t1,exttrailsource /home/oracle/ogg/dirdat/scott/es ,begin now
--添加远端队列
add rmttrail /home/oracle/ogg/dirdat/scott/t1, extract pp-t1,megabytes 1000
节点二:
新增抽取进程:
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;
添加进程
add extract ext-t2,tranlog,begin now
添加本地队列
add exttrail /home/oracle/ogg/dirdat/scott/es,extract ext-t2, megabytes 1000
新增投递进程:
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;
添加进程
add extract pp-t2,exttrailsource /home/oracle/ogg/dirdat/scott/es ,begin now
--添加远端队列
add rmttrail /home/oracle/ogg/dirdat/scott/t2, extract pp-t2,megabytes 1000
目标端:
新增复制进程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;
新增复制进程:
add replicat rp-t1,exttrail /home/oracle/ogg/dirdat/scott/t1,begin now,checkpointtable goldengate.checkpoint
新增复制进程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;
新增复制进程:
add replicat rp-t2,exttrail /home/oracle/ogg/dirdat/tbs01/t2,begin now,checkpointtable goldengate.checkpoint
创建测试表:
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);
目标库建立相应表结构:
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导出导入测试表数据。
启动进程:
1、 分别在各个源端和目标端启动start mgr
2、 启动各个源端抽取和投递进程
3、 数据导入目标端后,启动目标端复制进程
4、 使用info all查看各个进程状态,正常为running
5、 若出错,使用view report + 进程名查看报错并解决之。
测试:在源端表进行dml操作,观察目标端相应表数据变化。若两端一致,则ogg搭建成功
