After the beginner ogg, ogg to understand the basic principles and architecture, build on the progress to build a simple learning environment, in order to achieve the goal: the two tables sourcedb database: sourceuser.test01 and sourceuser.dept by ogg are synchronized to the database targetuser.test01 targetdb and targetuser.dept tables required to achieve DML (insert, update, delete) synchronization.
Basic environment
| Source | End goal | |
| Operating system version | redhat 6.7 | redhat 6.7 |
| Database Version | 11.2.0.4 | 11.2.0.4 |
| ogg version | Oracle GoldenGate 11.2.1.0.3 for Oracle 11g on Linux x86-64 | Oracle GoldenGate 11.2.1.0.3 for Oracle 11g on Linux x86-64 |
| Database / instance name | sourcedb/sourcedb | targetdb/targetdb |

(3.5) to create goldengat user
to create exclusive table space:
the Create TABLESPACE tbs_ogg datafile '/u01/app/oracle/product/11.2.0/db_1/dbs/sourcedb/tbs_ogg01.dbf' size 10m 100m AUTOEXTEND the Next ON MAXSIZE 30g;
Create a user:
the Create the User OGG OGG IDENTIFIED by default TABLESPACE tbs_ogg;
授予权限：
grant resource to ogg;
grant create session,alter session to ogg;
grant select any dictionary to ogg;
grant flashback any table to ogg;
grant alter any table to ogg;
grant select any table to ogg;
grant execute on dbms_flashback to ogg;
（3.6）创建测试用户及数据
create user sourceuser identified by sourceuser;
grant connect,resource to sourceuser;
conn sourceuser/sourceuser
- Create Table
Create Table Test01 (Number ID, name VARCHAR2 (20 is));
- to increase the master key
ALTER Test01 the Add Table Primary Key (ID);
- inserting the test data
INSERT INTO Test01 values (. 1, 'lijiaman');
INSERT Test01 values INTO (2, 'Xiaoming');
INSERT INTO Test01 values (. 3, 'xiaohua');
--创建表
create table dept (deptno number,dname varchar2(14),loc varchar2(13));
--增加主键
alter table dept add primary key(deptno);
--插入测试数据
insert into dept values(10,'ACCOUNTING','NEW YORK');
insert into dept values(20,'RESEARCH','DALLAS');
insert into dept values(30,'SALES','CHICAGO');
insert into dept values(40,'OPERATIONS','BOSTON');

Step1: create a path
$ [/ Home / Oracle] mkdir DataPump
$ [/ Home / Oracle] sqlplus SYS / the passwd AS SYSDBA
SQL> Create or Replace DIRECTORY exp_dir AS '/ Home / Oracle / datapump '
step2: authorize users to export data
the SQL> the GRANT the READ, the WRITE exp_dir the TO DIRECTORY the ON sourceuser;
the SQL> sourceuser the GRANT DATAPUMP_EXP_FULL_DATABASE the TO;

(Vii) test ogg replication
1. Insert sourceuser.test01 data in the table, there is new data found targetuser.test01 enter;
2. Execute delete from test01 at the source and submit the data in the target end targetuser.test01 are all delete;
3. the source table primary key column update operation: update dept set loc = 'sichuanthe target terminal is automatically updated;
4. the source table primary key column update operation: update dept set deptno = deptno +1, automatically updating the target terminal;
