一、OGG理论概念
目前许多客户环境都已经在广泛使用OGG。由于工作需要，近期我也会系统的学习下OGG，目前学习主要以OGG在Oracle数据库之间的同步来说明一些基本概念，后续看时间情况可能了解OGG对其他主流数据库的同步。
1.1 简单介绍
> 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。
> 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。
假设已有源数据库和目标数据库，且分别部署好OGG软件。
源数据库部署的OGG，简称源OGG；
目标数据库部署的OGG，简称目标OGG。
1.2 同步的过程
就是源OGG的EXTRACT进程从源数据库的联机redologs中抽取获得变化，把它写到本地trail文件中，然后源OGG的Data pump进程再从本地trail文件中抽取变化传给目标OGG的collector进程，目标的collector进程再把这些变化写入目标trail文件中，最后目标OGG的Replicat进程把目标trail文件中记录的变化应用到目标数据库中。
如果要同步的表数量比较多或是业务有区分，需要分开管理，OGG是支持分开多个extract进程，多个datapump进程，多个replicat进程，这样，可以启动或停止其中任意一类同步，而不影响其他的同步。
需要注意的是，每套OGG所有的进程都是由其Manager进程来管理的，也就是说Manager进程负责管理，启动关闭其他进程。OGG用组来表示它的进程，上面简单提到的extract、replicat这些进程，实际上需要各自的参数文件、检查点文件等。这些内容共同组成一个组，且每个组需要有一个组名字。
1.3 Oracle Golden Gate的简要体系图
- OGG的检查点信息
对于源OGG只能以文件形式默认存放在GGHOME/dirchk目录下，一个组对应一个文件。
而对于目标OGG检查点信息可以存放在数据库表中，且建议存放到数据库表中。
对于源数据库，如果要使用OGG，需要配置supplemental logging，原因是OGG相当于逻辑同步，除了要记录被修改的记录，还要把能够标识这条记录的信息同时记录在日志中。这样的话，Oracle默认情况是不达标的，需要额外开启supplemental logging才可以。
具体做法是：在数据库级别开启最小附加日志，在需要同步的表级别开启详细附加日志。
#数据库级别开启强制记录日志和最小附加日志：
SQL> alter database force logging;
SQL> alter database add supplemental log data;
#表级别开启详细附加日志（这里举例是jy用户下的t_second表）：
GGSCI> add trandata jy.t_second
对于目标数据库，配置检查点信息到目标数据库表中，具体做法：
1.目标GG的全局参数(./globals)配置
checkpointtable ggt.chkpt
2.命令添加checkpointtable
GGSCI> add checkpointtable ggt.chkpt
此外数据库需要启用Golden Gate复制参数：enable_goldengate_replication
SQL> alter system set enable_goldengate_replication=true;
二、测试实验
2.1 实验环境介绍
---------- ---------- | | | | | | | | | | | | | | | | | MySQL | ------------> | Oracle | | | | | | | | | | | | | ---------- ---------- Source Host :awen001(MySQL) Target Host :awen002(Oracle) IP Addr :192.168.1.21 IP Addr :192.168.1.22 Manager Account:root(MySQL) Manager Account:ggt_admin(Oracle) Srouce DB :test01(MySQL) Target Account :result01(Oracle) Source Table :Mar01 Target Table :Mar02 OS :CentOS 7.3 OS :CentOS 7.3

191004_fbo_ggs_Linux_x64_shiphome.zip
2.2 源端MySQL数据库配置
1. 创建操作系统MySQL用户
userdel mysql
groupadd -g 1007 mysql useradd -u 1103 -g mysql mysql echo "mysql" | passwd --stdin mysql id mysql
特别声明：创建MySQL用户的目的是要把Oracle Golden Gate安装到MySQL用户下，否则当OGG读取MySQL二进制索引文件[log-bin-index=/var/lib/mysql/binary-log.index]的时候，会因为没有相关权限而影响OGG的部署。
2. 镜像 & yum源
查看服务器挂载镜像以及yum源配置
[root@awen001 ~]# df -h | grep CentOS /dev/sr0 4.1G 4.1G 0 100% /run/media/root/CentOS 7 x86_64 [root@awen001 ~]# cat /etc/yum.repos.d/yum.repo [redhat7.6] name=redhat7.6 baseurl=file:///run/media/root/CentOS 7 x86_64/ gpgcheck=0 enabled=1 [root@awen001 ~]# yum repolist 已加载插件：fastestmirror, langpacks Loading mirror speeds from cached hostfile 源标识 源名称 状态 !redhat7.6 redhat7.6 3,831 repolist: 3,831
3. 安装数据库
CentOS 7自带MariaDB替代默认的MySQL客户端安装包。MariaDB数据库管理系统是MySQL的一个分支，主要由开源社区在维护，采用GPL授权许可 MariaDB的目的是完全兼容MySQL，包括API和命令行，使之能轻松成为MySQL的代替品。
yum install -y mariadb*

5. 设置root账户登陆密码
/usr/bin/mysql -u root -S /var/lib/mysql/mysql.sock
set password for 'root'@'localhost'=password('123');
flush privileges;
6. 查看参数是否生效
show variables like 'log_bin'; show master status;show variables like '%binlog%';

7. 创建即将同步的表
create database test01; use test01; show tables; create table Mar01 (id int,name varchar(10)) engine=innodb;
查看表结构和表属性

9. 源端配置OGG诸进程，尚不用启动进程
配置进程（组）名没有具体的规范：
对于复杂环境，第一位字母，local、immdiate、remote 分别对应：l、i、r；
后面根据进程属性属于extract、datapump、replicat 而分别对应：x、p、r；[mysql@awen001 ogg]$ ./ggsci

15. 模拟源端数据库业务持续运行
OGG的单向配置比较简单，但实际生产过程很多业务要求不间断运行， 所以往创建的表中不断插入数据，简单模拟在业务不间断运行场景下OGG的配置，
并观察进程信息。
--创建每隔10秒向gss_admin库的Mar01表插入一条数据的procedure； use test01
select count(*) from Mar01;
delimiter // create procedure per2() begin declare id int; set id=1; while id < 1000 do insert into Mar01(id,name) values(id,concat("fan",id)); select sleep(10); set id=id+1; end while; end // call per2(); ->//
16. 查看源端、目标端数据情况
MariaDB [test01]> select count(*) from Mar01; +----------+ | count(*) | +----------+ | 7 | +----------+ 1 row in set (0.00 sec) SQL> select count(*) from result01.Mar02; COUNT(*) ---------- 7
17. 查看目标端、远端进程信息

18. 进行dml测试
对表Mar01进行inert、delete、update操作，最后truncate该表。
MariaDB [(none)]> select count(*) from test01.Mar01; +----------+ | count(*) | +----------+ | 32 | +----------+ 1 row in set (0.00 sec) SQL> select count(*) from result01.Mar02; COUNT(*) ---------- 32 MariaDB [(none)]> insert into test01.Mar01 values (996,'YES'); Query OK, 1 row affected (0.00 sec) SQL> select * from result01.Mar02 where id=996; ID NAME ---------- -------------------- 996 YES MariaDB [(none)]> update test01.Mar01 set name='Yeap' where id=996; Query OK, 1 rows affected (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 0 SQL> select * from result01.Mar02 where id=996; ID NAME ---------- -------------------- 996 Yeap
MariaDB [(none)]> truncate test01.Mar01; Query OK, 0 rows affected (0.01 sec) MariaDB [(none)]> select count(*) from test01.Mar01; +----------+ | count(*) | +----------+ | 0 | +----------+ 1 row in set (0.00 sec) SQL> select count(*) from result01.Mar02; COUNT(*) ---------- 0
至此OGG异构配置完成，测试结束。
