占位符

1. Source创建Extract

add extract ext1,tranlog, begin now

add exttrail /u01/ggate/dirdat/lt, extract ext1

view params ext1

2. Source创建Pump

add extract dpump,exttrailsource /u01/ggate/dirdat/lt

add rmttrail /u01/ggate/dirdat/lt, extract dpump

view params dpump

3. Target创建Replicat

3.1 配置进程的checkpoint

edit params ./GLOBAL

GGSCHEMA ggate

CHECKPOINTTABLE ggate.checkpoint

3.2 连接DB的ggate用户，在DB中创建checkpoint表

add checkpoint tableggate.checkpoint

3.3 创建replicat group

add replicatrep1,exttrail /u01/ggate/dirdat/lt, checkpointtable ggate.checkpoint

3.4 修改参数

view params rep1

4. 启动Extract / Dump / Replicat 进程

5. 测试

start ext1

info ext1

info dpump

start rep1

info rep1

验证一下：

--Source DB：

SQL> conn dave/dave;      

Connected.

 

SQL> select count(*) from pdba;

 COUNT(*)

----------

  2706623

 

--Target DB：

SQL> select count(*) from pdba;

 COUNT(*)

----------

  2706623

 

在Source DB insert 一条数据：

SQL> insert into pdba values(2,sysdate);

1 row created.

 

SQL> commit;

Commit complete.

 

SQL> select count(*) from pdba;

 COUNT(*)

----------

  2706624

 

到Target DB 查询：

SQL> select count(*) from pdba;

 COUNT(*)

----------

  2706624
