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

2.2 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

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*
[root@awen001 ~]# yum install -y mariadb*

#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port = <port>
#
# binary logging - not required for slaves, but recommended

8. 安装MySQL数据库的GoldenGate软件（MySQL用户安装）
创建安装目录并解压安装包
su - mysql
mkdir -p /home/mysql/ogg
mv ggs_Linux_x64_MySQL_64bit.tar ogg/
cd ogg/
tar -xvf ggs_Linux_x64_MySQL_64bit.tar
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(*)
----------

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)
