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 mysqlgroupadd -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

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*

#
# MariaDB programs look for option files in a set of

# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id       = 1

# Replication Slave (comment out master section to use this)
#
# 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
#log-bin=mysql-bin

--创建OGG数据目录
mkdir -p /u01/app/ogg

--在目标端创建完OGG子目录以后,将defgen文件复制到指定位置
mv defgen.prm ogg/dirdef

--开启监听
lsnrctl status
--数据库开启GoldenGate参数
alter system set enable_goldengate_replication=true sid='*';

11. 目标端创建OGG管理用户和测试用户以及测试表

--创建OGG管理用户
create user ggt_admin identified by ggt_admin;
grant dba to ggt_admin;

--创建OGG测试用户
create user result01 identified by result01;
grant resource,connect to result01;

--在该用户下创建测试表
conn result01/result01 
create table result01.Mar02(id int,name char(10));

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 test01select 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。
