一  GoldenGate简介

Oracle Golden Gate软件是一种基于日志的结构化数据复制备份软件,它通过解析源 数据库在线日志或归档日志获得数据的增量变化,再将这些变化应用到目标数据库,从而实现源数据库与目标数据库同步。Oracle Golden Gate可以在异构的IT基础结构(包括几乎 所有常用操作系统平台和数据库平台)之间实现大量数据亚秒一级的实时复制,从而在可以 在应急系统、在线报表、实时数据仓库供应、交易跟踪、数据同步、集中/分发、容灾、数据库升级和移植、双业务中心等多个场景下应用。同时,Oracle Golden Gate 可以实现一 对一、广播(一对多)、聚合(多对一)、双向、点对点、级联等多种灵活的拓扑结构。

二、技术结构

和传统的逻辑复制一样,Oracle GoldenGate 实现原理是通过抽取源端 的redo log或者archive log,然后通过TCP/IP投递到目标端,最后解析还原应用到目标端,使目标端实现同源端数同步。以下是OracleGoldenGate的技术架。

三、OGG进程

1、Manager进程

Manager进程是GoldenGate的控制进程,运行在源端和目标端上。它主要作用有以下几个方面:启动、监控、重启Goldengate的其他进程, 报告错误及事件,分配数据存储 空间,发布阀值报告等。

2、Extract进程

Extract运行在数据库源端,负责从源端数据表或者日志中捕获数据。

3、Pump进程

pump进程运行在数据库源端。

其作用是如果源端使用了本地的trail文件, 那么pump 进程就会把trail以数据块的形式通过TCP/IP协议发送到目标端,这通常也是推荐的 方式。pump进程本质是extract进程的一种特殊形式,如果不使用trails文件,那么 就是extract进程在抽取完数据以后,直接投递到目标端。

4.Trail文件

为了更有效、更安全的把数据库事务信息从源端投递到目标端。GoldenGate引进 trail文件的概念。前面提到extract抽取完数据以后Goldengate会将抽取的事务信息转化为一种GoldenGate专有格式的文件。然后pump负责把源端的trail文件投递到目标端, 所以源、目标两端都会存在这种文件。trail文件存在的目的旨在防止单点故障,将事务信 息持久化,并且使用checkpoint机制来记录其读写位置,如果故障发生,则数据可以根据 checkpoint记录的位置来重传。

5.Replicat进程

Replicat进程,通常我们也把它叫做应用进程。运行在目标端,是数据传递的最后一站,负责读取目标端trail文件中的内容,并将其解析为DML或DDL语句,然后应用到目标数据库中。

6.GGSCI

GGSCI是GoldenGate Software Command Interface 的缩写,它提供了十分丰富的 命令来对Goldengate进行各种操作,如创建、修改、监控GoldenGate进程等等。

四、应用的拓展结构、支持平台和数据库

五、OGG安装

1、检测安装环境

[oracle@rh6 ogg]$ uname -a

Linux rh6.cuug.net 2.6.32-71.el6.i686 #1 SMP Wed Sep 1 01:26:34 EDT 2010 i686 i686 i386 GNU/Linux

[oracle@rh6 ogg]$ arch

i686

2、安装OGG软件

[oracle@rh6 ogg]$ mkdir -p /u01/ogg

[oracle@rh6 ogg]$ ls -l

total 85912

-rw-r----- 1 oracle oinstall 87966150 Sep 10 11:33 ogg112101_fbo_ggs_Linux_x86_ora11g_32bit.zip

注意:下载的OGG 11g版本有32位和64位,如果在操作系统为32位,安装64位的OGG,将出现以下错误

“不可执行的二进制文件”

[oracle@rh6 ogg]$ unzip ogg112101_fbo_ggs_Linux_x86_ora11g_32bit.zip

[oracle@rh6 ogg]$ tar xvf fbo_ggs_Linux_x86_ora11g_32bit.tar

3、执行ggsci脚本,建立相关目录

[oracle@rh6 ogg]$ ./ggsci

新建出来的目录有:

--dirchk          Checkpoint files存放检查点(Checkpoint)文件 (和Oracle的checkpoint含义不同,如oralce的一个实例失败,从最近一次的checkpoint开始recorver, oracle的一次 checkpoint是让dbwrt进程把被修改的数据从数据缓冲区中写入数据文件。而OGG的checkpoint是OGG捕捉了很多事务日志,哪些被 传输了,哪些未被传输。每隔一段时间,执行一次checkpoint,之前的所有数据都要传送过去。如果soure or target db断电了,那下次启动的时候,就要支持断点续传,那那个断点位置就是最后一次OGG执行checkpoint的位置) 

--dirdat          GoldenGate trails,  存放Trail与Extract文件

--dirdef          Data Definition files,过DEFGEN工具生成的源或目标的数据定义文件

--dirprm          Parameter files, 存放参数文件

--dirpcs          Process status files, 存放进程状态文件

--dirrpt          Report files, 存放进程报告文件

--dirsql          SQL script files,存放SQL脚本文件

--dirtmp          Temporary files,当事务所需要的内存超过已分配内存时,缺省存储于此

@至此,OGG在linux下安装基本完成,后面将进入OGG的基本配置

OGG基本配置(单向传输)

1、数据库配置(Source DB)

建立Tablespace:

11:58:56 SYS@ prod >create tablespace ogg_tbs

11:59:12  2  datafile '/u01/app/Oracle/oradata/prod/oggtbs1.dbf' size 100m ;

建立ogg用户:

12:01:17 SYS@ prod >create user ogg identified by ogg default tablespace ogg_tbs temporary tablespace temp quota unlimited on ogg_tbs;

User created.

用户授权:

12:01:39 SYS@ prod >grant connect,resource to ogg;

Grant succeeded.

12:01:55 SYS@ prod >grant create session,alter session to ogg;

Grant succeeded.

12:02:18 SYS@ prod >grant select any dictionary,select any table to ogg;

Grant succeeded.

12:02:42 SYS@ prod >grant alter any table to ogg;

Grant succeeded.

12:02:53 SYS@ prod >grant flashback any table to ogg;

Grant succeeded.

12:03:03 SYS@ prod >grant execute on dbms_flashback to ogg;

Grant succeeded.

在Database上启用附加日志功能:

12:19:26 SYS@ prod >select SUPPLEMENTAL_LOG_DATA_MIN from v$database;

SUPPLEME

--------

NO

12:20:53 SYS@ prod >alter database add supplemental log data;

Database altered.

数据库应为归档模式:

12:21:10 SYS@ prod >archive log list;

Database log mode              Archive Mode

Automatic archival            Enabled

Archive destination            /dsk4/arch_prod

Oldest online log sequence    78

Next log sequence to archive  80

Current log sequence          80

13:22:45 SYS@ prod >select force_logging from v$database;

FOR

---

NO

13:24:22 SYS@ prod >alter database force logging;

Database altered.

13:24:30 SYS@ prod >select force_logging from v$database;

FOR

---

YES

建立用于传输测试的Table:

12:12:26 SCOTT@ prod >create table emp_ogg as select * from  emp;

Table created.

12:12:40 SCOTT@ prod >alter table emp_ogg add constraint pk_ogg primary

key(empno);

注意:Oracle建议给所有要复制的表建立主键或唯一键

2、数据库配置(Target DB)

建立Tablespace:

12:07:50 SYS@ prod >create tablespace ogg_tbs

12:08:09  2  datafile '/u01/app/oracle/oradata/prod/oggtbs1.dbf' size 100m;

12:08:47 SYS@ prod >create user ogg identified by ogg default tablespace ogg_tbs temporary tablespace temp quota unlimited on ogg_tbs;

User created.

用户授权:

12:09:44 SYS@ prod >grant connect,resource to ogg;

Grant succeeded.

12:10:06 SYS@ prod >grant create session ,alter session to ogg;

Grant succeeded.

12:10:20 SYS@ prod >grant select any table,select any dictionary to ogg;

Grant succeeded.

12:10:45 SYS@ prod >grant create table to ogg;

创建测试Table:

12:13:47 SCOTT@ prod >create table emp_ogg as select * from  emp;

Table created.

12:14:04 SCOTT@ prod >grant all on emp_ogg to ogg;

Grant succeeded.
3、OGG配置(source)
