一、环境规划
- 实现目标：配置OGG，实现从Oracle到kafka数据增量同步。同步消息格式为json。
- 主机规划：
身份 | 主机名 | 版本 | IP | OGG版本 |
源端 | orcldb | Release 11.2.0.4.0 | 172.16.10.152 | OGG-12.3.0.1.4 |
目标端 | kafka_2.11-1.1.1 | 172.16.100.241 | OGG_BigData_Linux_x64_12.3.2.1.1 |
二、安装包下载
- Oracle OGG下载地址：https://www.oracle.com/middleware/technologies/goldengate-downloads.html#license-lightbox
- kafka OGG下载地址：https://www.oracle.com/middleware/technologies/goldengate-downloads.html#license-lightbox（BigData）
三、搭建过程
1.Oracle部署
1）系统配置：
#修改主机名，防火墙关闭，selinux关闭等
[root@172-16-10-152 ~]# hostnamectl set-hostname orcldb
[root@172-16-10-152 ~]# su -

[root@orcldb src]# source /etc/profile
2）安装相应软件包，创建用户，组以及相关文件夹
[root@orcldb ~]# yum -y install binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat unixODBC unixODBC-devel
[root@orcldb src]# groupadd -g 501 oinstall
[root@orcldb src]# groupadd -g 502 dba
[root@orcldb src]# groupadd -g 503 oper
[root@orcldb src]# useradd -u 502 -g oinstall -G dba,oper oracle
[root@orcldb src]# echo oracle | passwd --stdin oracle
Changing password for user oracle.
passwd: all authentication tokens updated successfully.
[root@orcldb src]# mkdir /u01/app/oracle -pv
[root@orcldb ~]# mkdir -pv /u01/app/oracle/product/11.2.0/db_home1
[root@orcldb ~]# chown oracle.oinstall /u01 -R
[root@orcldb src]# chown -R oracle.oinstall database/
3）静默安装Oracle

4.OGG配置（含测试准备）
Oracle配置：
1）Oracle创建专用的表空间，并创建复制用户授权
#创建表空间数据文件存放目录
[root@orcldb ~]# mkdir -p /u01/app/oracle/oggdata/orcl
[root@orcldb ~]# chown -R oracle:oinstall /u01/app/oracle/oggdata/orcl
#创建表空间
SQL> create tablespace oggtbs datafile '/u01/app/oracle/oggdata/orcl/oggtbs01.dbf' size 1000M autoextend on;
Tablespace created.
#创建用户并授权
SQL> create user ogg identified by ogg default tablespace oggtbs;
User created.
SQL> grant dba to ogg;#这里权限实际应该比较严谨，只是为了方便
Grant succeeded.
2）Oracle配置OGG全局变量
[oracle@orcldb ogginstall]$ ./ggsci
GGSCI (orcldb) 1> dblogin userid ogg password ogg
Successfully logged into database.
GGSCI (orcldb as ogg@orcl) 2> edit param ./globals
oggschema ogg
allowOutputDir /opt/ogg/dirdat --这里这个是目标端复制文件的位置 OGG12的新特性
3）Oracle配置OGG管理器mgr
GGSCI (orcldb as ogg@orcl) 4> edit param mgr
PORT 7809 --PORT mgr的默认监听端口
DYNAMICPORTLIST 7810-7909 --DYNAMICPORTLIST 动态端口集，当上述指定的端口不可用时在这个区间选择1个，最大范围256
AUTORESTART EXTRACT *,RETRIES 5,WAITMINUTES 3 --表示重启所有EXTRACT进程，每次间隔3分钟 最多可以执行5次
PURGEOLDEXTRACTS ./dirdat/*,usecheckpoints, minkeepdays 3 --trail文件定期清理
4）Oracle创建测试用户和测试表
SQL> create user test_ogg identified by test_ogg default tablespace users;
User created.
SQL> grant dba to test_ogg;
Grant succeeded.
SQL> conn test_ogg/test_ogg;
Connected.
SQL> create table test_ogg(id int ,name varchar(20),primary key(id));
Table created.
5）Oracle配置OGG添加待复制表
GGSCI (orcldb as ogg@orcl) 5> add trandata test_ogg.test_ogg
2020-08-19 22:32:12 INFO OGG-15132 Logging of supplemental redo data enabled for table TEST_OGG.TEST_OGG.
2020-08-19 22:32:12 INFO OGG-15133 TRANDATA for scheduling columns has been added on table TEST_OGG.TEST_OGG.
2020-08-19 22:32:12 INFO OGG-15135 TRANDATA for instantiation CSN has been added on table TEST_OGG.TEST_OGG.
GGSCI (orcldb as ogg@orcl) 6> info trandata test_ogg.test_ogg
Logging of supplemental redo log data is enabled for table TEST_OGG.TEST_OGG.
Columns supplementally logged for table TEST_OGG.TEST_OGG: "ID".
Prepared CSN for table TEST_OGG.TEST_OGG: 1397441
6）Oracle配置OGG extract进程，并添加extract进程
GGSCI (orcldb as ogg@orcl) 7> edit param extkafka
extract extkafka --进程名称
dynamicresolution --动态解析
SETENV (ORACLE_SID = "orcl") --设置环境变量，Oracle sid
SETENV (NLS_LANG = "american_america.AL32UTF8") --设置环境变量，字符集
userid ogg,password ogg --OGG连接数据库的用户和密码
exttrail /ogg/ogginstall/dirdat/to --trail文件的保存路径和文件名，注意只能2位其余由OGG不齐。一共8位。
table test_ogg.test_ogg; --table 指的就是表名，支持通配符*，注意必须用;结尾
# 添加extract进程
GGSCI (orcldb as ogg@orcl) 8> add extract extkafka,tranlog,begin now
EXTRACT added.
# 添加trail文件与extract绑定
GGSCI (orcldb as ogg@orcl) 9> add exttrail /ogg/ogginstall/dirdat/to,extract extkafka
EXTTRAIL added.
7）Oracle配置OGG pump进程（与extract类似用来发送trail到目标端）
GGSCI (orcldb as ogg@orcl) 10> edit param pukafka
extract pukafka --进程名称
passthru --禁止OGG与Oracle交互
dynamicresolution --动态解析
userid ogg,password ogg --OGG连接数据库的用户和密码
rmthost 172.16.100.241 mgrport 7809 --目标端kafka mgr服务的地址和监听端口
rmttrail /opt/ogg/dirdat/to --目标端trail文件存储位置，这里和源端存储位置不同，这也是前面全局变量为什么加上新参数的原因
table test_ogg.test_ogg; --table 指的就是表名，支持通配符*，注意必须用;结尾
#分别将本地trail文件和目标端的trail文件绑定到extract进程
GGSCI (orcldb as ogg@orcl) 11> add extract pukafka,exttrailsource /ogg/ogginstall/dirdat/to
EXTRACT added.
GGSCI (orcldb as ogg@orcl) 12> add rmttrail /opt/ogg/dirdat/to,extract pukafka
RMTTRAIL added.
8）Oracle配置define文件
Oracle与MySQL，Hadoop集群（HDFS，Hive，kafka等）等之间数据传输可以定义为异构数据类型的传输，故需要定义表之间的关系映射
GGSCI (orcldb) 4> edit param test_ogg
defsfile /ogg/ogginstall/dirdef/test_ogg.test_ogg
userid ogg,password ogg
table test_ogg.test_ogg;
在Oracle OGG主目录下执行
[oracle@orcldb ogginstall]$ pwd
/ogg/ogginstall
[oracle@orcldb ogginstall]$ ./defgen paramfile dirprm/test_ogg.prm
...

kafka配置：（相同参数不再说明）
1）启动kafka服务
[root@kafka kafka]# bin/zookeeper-server-start.sh config/zookeeper.properties
[root@kafka kafka]# bin/kafka-server-start.sh config/server.properties
[root@kafka kafka]# jps
26305 ScheduleMain

20247 start.jar
20120 Kafka
30521 EngineMain
13626 DataNode
7452 JobHistoryServer
24573
2）kafka配置管理器mgr
GGSCI (kafka) 1> edit param mgr
PORT 7809
DYNAMICPORTLIST 7810-7909
AUTORESTART EXTRACT *,RETRIES 5,WAITMINUTES 3
PURGEOLDEXTRACTS ./dirdat/*,usecheckpoints, minkeepdays 3
3）kafka配置checkpoint
checkpoint复制可追溯的一个偏移量记录，在全局配置里添加checkpoint表即可。
GGSCI (kafka) 2> edit param ./GLOBALS
CHECKPOINTTABLE test_ogg.checkpoint
4）kafka配置replicate进程
GGSCI (kafka) 3> edit param rekafka
REPLICAT rekafka --relicate进程名字
sourcedefs /ogg/ogginstall/dirdef/test_ogg.test_ogg --define的映射文件
TARGETDB LIBFILE libggjava.so SET property=dirprm/kafka.props --TARGETDB LIBFILE即定义kafka一些库文件以及配置文件位置
REPORTCOUNT EVERY 1 MINUTES, RATE --复制任务的报告生成频率
GROUPTRANSOPS 10000 --以事务传输时，事务合并的单位，减少IO操作
MAP test_ogg.test_ogg, TARGET test_ogg.test_ogg; --源端与目标端的映射关系
5）设置kafka的配置文件
[root@kafka ogg]# cd /opt/ogg/dirprm/
[root@kafka dirprm]# ls
[root@kafka dirprm]# vim kafka.props
gg.handlerlist=kafkahandler
gg.handler.kafkahandler.type=kafka
gg.handler.kafkahandler.KafkaProducerConfigFile=custom_kafka_producer.properties
gg.handler.kafkahandler.topicMappingTemplate=test_ogg #kafka topic名称，OGG12有修改
gg.handler.kafkahandler.format=json
gg.handler.kafkahandler.mode=op
gg.classpath=dirprm/:/opt/dtstack/DTBase/kafka/libs/*:/opt/ogg/:/opt/ogg/lib/*
[root@kafka dirprm]# pwd
/opt/ogg/dirprm
[root@kafka dirprm]# vim custom_kafka_producer.properties

value.serializer=org.apache.kafka.common.serialization.ByteArraySerializer
key.serializer=org.apache.kafka.common.serialization.ByteArraySerializer
batch.size=102400
linger.ms=10000
6）kafka配置添加trail文件到replicate进程
GGSCI (kafka) 1> add replicat rekafka exttrail /opt/ogg/dirdat/to,checkpointtable test_ogg.checkpoint
REPLICAT added.
四、测试
启动两端进程：按照以下顺序
源端mgr ---> 目标端mgr ---> 源端extract ---> 源端pump ---> 目标replicate
本例中在OGG命令行中执行
GGSCI (orcldb) 1> start mgr
GGSCI (kafka) 1> start mgr
GGSCI (orcldb) 2> start extkafka
GGSCI (orcldb) 3> start pukafka
GGSCI (kafka) 2> start rekafka
