DBA_Oracle GoldenGate三步骤Dump / Extract / Relicat
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
