文档课题：运用ogg实现oracle10g到19cschema级别的同步.

源端：192.168.133.108 数据库oracle 10.2.0.4 64位，实例名：orcl

目标端：192.168.133.109数据库oracle19.16.0.0 64位，实例名：simdb

ogg安装包：

源端：fbo_ggs_Linux_x64_ora10g_64bit.tar

目标端：191004_fbo_ggs_Linux_x64_shiphome.zip

说明：源端与目标端的ogg安装包不同.

核心思想：利用导入导出初始化数据后通过OGG同步增量数据.

进程介绍：

manager：控制ogg启动、状态、停止等.

extract：捕获源端数据，运用其内在checkpoint机制，周期性检查并记录其读写位置，通常是写入到本地trail文件.

pump：把trail文件以数据块形式通过tcp/ip协议发送到目标端.

replicat：读取目标端trail文件内容，并将其解析为dml或ddl语句，然后应用到目标数据库中.

原理图如下：

注意：以下是在ogg同步过单表的基础上进行测试以达到同步schema的文档记录.ogg同步单表的请查看此前文档.

1、系统检查

--源端

[oracle@leo-10g-ogg~]$ cat /etc/*release

EnterpriseLinux Enterprise Linux Server release 5.11 (Carthage)

--目标端

sys@SIMDB > select userenv('language') from dual;

--建directoryname.

4.1.3、添加附加日志

Loggingof supplemental redo data enabled for table SCOTT.TESTDDL.

注意：

a、数据库附加日志打开后还需要对每张表执行addtrandata吗？答案是肯定的，如果不执行add trandata，insert同步没有问题（ORACLE数据库），但在同步update或delete时，就会因为丢失主键报同步错误.不开启表级的最小附加日志，update的redo信息不记录没有进行更新的字段信息，如主键不更新的话主键不记录在redo中，所以会导致同步失败.

b、addschematrandata scott在oracle 10.2.0.4执行会报错“OGG-01778，FeatureADD/INFO/DELETE SCHEMATRANDATA unsupported on the current database version.Upgrade database version to Oracle 11g or higher”.以上采用的addtrandata scott.*的语句.

区别如下：

add schematrandatascott --scott用户

addtrandata scott.* --scott用户下的所有表

7、数据验证
7.1、DML测试

--源端模拟插入一条数据.

SQL>conn scott/tiger

Connected.

SQL>select * from dept;

DEPTNO DNAME LOC

------------------------ -------------

10 ACCOUNTING NEW YORK

20 RESEARCH DALLAS

30 SALES CHICAGO

40 OPERATIONS BOSTON

SQL>insert into dept values (50,'IT','ChongQing');

1row created.

SQL>commit;

Commitcomplete.

--目标端查询.

sys@SIMDB > conn scott/tiger

Connected.

scott@SIMDB > select * from dept;

DEPTNO DNAME LOC

------------------------ -------------

10 ACCOUNTING NEW YORK

20 RESEARCH DALLAS

30 SALES CHICAGO

40 OPERATIONS BOSTON

50 IT ChongQing

7.2、DDL测试

--源端修改字段长度.

SQL>desc dept;

Name Null? Type

------------------------------------------------- ----------------------------

DEPTNO NOT NULL NUMBER(5)

DNAME VARCHAR2(14)

LOC VARCHAR2(13)

SQL>alter table dept modify deptno number(8);

Tablealtered.

SQL>desc dept

Name Null? Type

----------------------- ------------------------

DEPTNO NOT NULL NUMBER(8)

DNAME VARCHAR2(14)

LOC VARCHAR2(13)

--目标端查询.

scott@SIMDB > desc dept

Name Null? Type

----------------------- ------------------------

DEPTNO NOT NULL NUMBER(8)

DNAME VARCHAR2(14)

LOC VARCHAR2(13)

7.3、增加约束检查

--源端查询

SQL>set line 200

SQL>select owner,constraint_name,constraint_type,table_name,index_name fromuser_constraints where table_name='DEPT'

OWNER CONSTRAINT_NAME C TABLE_NAME INDEX_NAME

------------------------------------------------------------ - ------------------------------------------------------------

SCOTT PK_DEPT P DEPT PK_DEPT

--目标端查询

scott@SIMDB > selectowner,constraint_name,constraint_type,table_name,index_name fromuser_constraints where table_name='DEPT';

OWNER CONSTRAINT_NAME C TABLE_NAME INDEX_NAME

------------------------------ - -------------------- --------------------

SCOTT PK_DEPT P DEPT PK_DEPT

--源端增加唯一约束

SQL>alter table dept add constraint uk_dept_dname unique (dname);

Tablealtered.

SQL>select owner,constraint_name,constraint_type,table_name,index_name from user_constraintswhere table_name='DEPT';

OWNER CONSTRAINT_NAME C TABLE_NAME INDEX_NAME

------------------------------------------------------------ - ------------------------------------------------------------

SCOTT PK_DEPT P DEPT PK_DEPT

SCOTT UK_DEPT_DNAME U DEPT UK_DEPT_DNAME

--目标端查询

scott@SIMDB > selectowner,constraint_name,constraint_type,table_name,index_name fromuser_constraints where table_name='DEPT';

OWNER CONSTRAINT_NAME C TABLE_NAME INDEX_NAME

------------------------------ - -------------------- --------------------

SCOTT PK_DEPT PDEPT PK_DEPT

SCOTT UK_DEPT_DNAME U DEPT UK_DEPT_DNAME

7.4、建表测试

--源端建testddl表.

SQL>create table testddl (id number(10));

Tablecreated.

SQL>begin

2 fori in 1..1000 loop

3 insert into testddl (id) values (i);

4 endloop;

5 end;

6 /

PL/SQLprocedure successfully completed.

SQL>commit;

Commitcomplete.

SQL>select count(*) from testddl;

COUNT(*)

----------

1000

--目标端查询.

scott@SIMDB > select table_name from user_tables;

TABLE_NAME

--------------------

TESTDDL

DEPT

EMP

BONUS

SALGRADE

scott@SIMDB > select count(*) from testddl

COUNT(*)

----------

1000

说明：以上为ogg实现单个schema级别的复制，若要实现数据库级别的复制，建议将需要复制的schema分别添加进抓取、投递、应用进程.
