installer 4.5

前沿拓展：

目的：测试使用OGG将数据单向同步到Kafka上。

简要说明：Kafka使用单节点单Broker部署；单独部署简单ZooKeeper；需要使用到JAVA1.8；OGG需要2个版本，一个for oracle版本，一个Big Data。

1 环境说明

oracle

11.2.0.4

zookeeper

apache-zookeeper-3.6.2-bin.tar.gz

export JAVA_HOME=/usr/local/jdk1.8.0_181

export PATH=$JAVA_HOME/bin:$PATH

3 ZOOKEEPER安装3.1 ZooKeeper 简单安装

[root@test01 ~] tar -zxvf apache-zookeeper-3.6.2-bin.tar.gz -c /usr/local

[root@test01 ~] mv /usr/local/apache-zookeeper-3.6.2-bin /usr/local/apache-zookeeper-3.6.2

3.2 编辑参数文件zoo.cfg

[root@test01 ~] cd /usr/local/apache-zookeeper-3.6.2

进入Zookeeper的config目录下

拷贝zoo_sample.cfg文件重命名为zoo.cfg，第二修改dataDir属性,其他参数保持不变

[root@test01 conf]# cp zoo_sample.cfg zoo.cfg

[root@test01 conf]# vi zoo.cfg

# 数据的存放目录

dataDir=/usr/local/apache-zookeeper-3.6.2/zkdata

# 端口，默认就是2181

clientPort=2181

3.3 环境变量配置

[root@test01 ~] vi /etc/profile –在末尾添加

export ZOOKEEPER_HOME=/usr/local/apache-zookeeper-3.6.2

2702 Jps

2287 Kafka

4.6 Kafka测试

[root@test01 ~]# cd /usr/local/kafka_2.13-2.7.0/bin

创建topic

[root@test01 bin]#./kafka-topics.sh –create –zookeeper localhost:2181 –replication-factor 1 –partitions 1 –topic test

Created topic test.

查看所有的topic信息

[root@test01 bin]# ./kafka-topics.sh –list –zookeeper localhost:2181

test

查看到返回值’test’ 说明创建成功！

5. OGG源端安装5.1解压安装包

[oracle@oracle01 ~]$unzip fbo_ggs_Linux_x64_shiphome.zip

5.2安装：(图形化安装略)

[oracle@oracle01 ~]$ cd fbo_ggs_Linux_x64_shiphome/Disk1

[oracle@oracle01 Disk1]$./runInstaller

…..此处略……..

使用图形化安装界面安装完成后，目录直接已经生成好了！！

5.3 检查数据库配置和更改参数5.3.1 源端数据需要处于归档模式,且开启supplemental log和force_logging

SQL> archive log list;

Database log mode Archive Mode

Automatic archival Enabled

Archive destination USE_DB_RECOVERY_FILE_DEST

Oldest online log sequence 8

Next log sequence to archive 10

Current log sequence 10

SQL> select name,supplemental_log_data_min,force_logging from v$database;

NAME SUPPLEMENTAL_LOG_DATA_MI FORCE_LOG

————————— ———————— ———

TDB01 YES YES

如果需要更改，使用下面语句：

alter database archivelog;

Alter database force logging;

alter database add supplemental log data;

ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION = TRUE SCOPE=BOTH;

5.3.2 创建OGG用户和单独表空间

create tablespace ts_ogg datafile '/u01/app/oracle/oradata/tdb01/ts_ogg01.dbf' size 200M AUTOEXTEND on extent management local segment space management auto;

create user ggusr identified by ggusr default tablespace ts_ogg;

为了方便直接给予DBA权限：

grant resource,connect,dba to ggusr;

5.3.3 配置测试用户

alter user scott identified by scott account unlock;

grant select_catalog_role to scott;

在scott用户下创建新的表，做测试表：

create table test_ogg(id int ,name varchar(20),primary key(id));

5.4 配置MGR

GGSCI (oracle01) 3> edit param mgr

PORT 7809

DYNAMICPORTLIST 7810-7909

–AUTORESTART EXTRACT *,RETRIES 5,WAITMINUTES 3

PURGEOLDEXTRACTS ./dirdat/*,usecheckpoints, minkeepdays 3

LAGREPORTHOURS 1

LAGINFOMINUTES 30

LAGCRITICALMINUTES 45

注释：

PORT即mgr的默认**端口；

DYNAMICPORTLIST动态端口列表，当指定的mgr端口不可用时，会在这个端口列表中选择一个，最大指定范围为256个；

AUTORESTART重启参数设置表示重启所有EXTRACT进程，最多5次，每次间隔3分钟；

PURGEOLDEXTRACTS即TRAIL文件的定期清理

5.5 添加**附加日志信息

使用ogg用户ggusr登录

##GGSCI (oracle01) 5> dblogin userid ggusr, password ggusr

Successfully logged into database.

GGSCI (oracle01 as ggusr@tdb01) 6> info trandata scott.test_ogg

Logging of supplemental redo log data is disabled for table SCOTT.TEST_OGG.

GGSCI (oracle01 as ggusr@tdb01) 7> add trandata scott.test_ogg

Logging of supplemental redo data enabled for table SCOTT.TEST_OGG.

TRANDATA for sche**ng columns has been added on table 'SCOTT.TEST_OGG'.

TRANDATA for instantiation CSN has been added on table 'SCOTT.TEST_OGG'.

5.6 配置EXTRACT抽取进程

GGSCI (oracle01) 18> edit param extkafka

extract extkafka

setenv (ORACLE_SID=tdb01)

setenv (ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)

Setenv (NLS_LANG="AMERICAN_AMERICA.UTF8")

userid ggusr,password ggusr

exttrail ./dirdat/ka

table scott.test_ogg;

添加进程：

–add extract extkafka,tranlog,begin now

绑定trail文件：

–add exttrail ./dirdat/ka,extract extkafka

5.7 配置PUMP投递进程(EXTRACT进程的另一种用法)

GGSCI (oracle01) 19> edit param pukafka

extract pukafka

setenv (ORACLE_SID=tdb01)

setenv (ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)

passthru

dynamicresolution

userid ggusr,password ggusr

rmthost 192.168.141.107,mgrport 7809

rmttrail ./dirdat/pa

table scott.test_ogg;

注释：

第一行指定extract进程名称；

passthru即禁止OGG与Oracle交互，我们这里使用pump逻辑传输，故禁止即可；

dynamicresolution动态解析；

userid ogg,password ogg即OGG连接Oracle数据库的帐号密码

rmthost和mgrhost即目标端(kafka)OGG的mgr服务的地址以及**端口；

rmttrail即目标端trail文件存储位置以及名称

将本地文件和目标端文件绑定到PUMP进程中：

add extract pukafka,exttrailsource ./dirdat/ka

add rmttrail ./dirdat/pa,extract pukafka

5.8 配置define文件用来定义表之间的关系映射

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，需要定义表之间的关系映射

GGSCI (oracle01) 1> edit param test_ogg

defsfile /u01/ogg12.2/dirdef/scott.test_ogg

userid ggusr,password ggusr

table scott.test_ogg;

#GGSCI (oracle01) 3> view param test_ogg

defsfile /u01/ogg12.2/dirdef/scott.test_ogg

userid ggusr,password ggusr

table scott.test_ogg;

在OGG主目录下执行(oracle用户)：

./defgen paramfile dirprm/test_ogg.prm

—执行后会在/u01/ogg12.2/dirdef目录下生成相关文件scott.test_ogg

[oracle@oracle01 ogg12.2]$ ./defgen paramfile dirprm/test_ogg.prm

scp /u01/ogg12.2/dirdef/scott.test_ogg root@192.168.141.107:/u01/ogg12.3/dirdef

6.O GG目标端(kafka)安装6.1 确认zookeeper服务，kafka服务开启

[root@test01 dirdef]# jps

3760 Jps

1971 QuorumPeerMain

2287 Kafka

6.2 配置MGR

GGSCI (test01) 3> edit param mgr

PORT 7809

DYNAMICPORTLIST 7810-7909

–AUTORESTART EXTRACT *,RETRIES 5,WAITMINUTES 3 —暂时不要

PURGEOLDEXTRACTS ./dirdat/*,usecheckpoints, minkeepdays 3

LAGREPORTHOURS 1

LAGINFOMINUTES 30

LAGCRITICALMINUTES 45

6.3 配置checkpoint

checkpoint即**可追溯的一个偏移量记录，在全局配置里添加checkpoint表即可。

GGSCI (test01) 14>edit param ./GLOBALS

CHECKPOINTTABLE ggusr.checkpoint

6.4 配置replicate进程

GGSCI (test01) 6> EDIT PARAMS rekafka

replicat rekafka

sourcedefs /u01/ogg12.3/dirdef/scott.test_ogg

TARGETDB LIBFILE libggjava.so SET property=dirprm/kafka.props

REPORTCOUNT EVERY 1 MINUTES, RATE

GROUPTRANSOPS 10000

map scott.test_ogg,target scott.test_ogg;

注释：

REPLICATE rekafka定义rep进程名称；

sourcedefs 即是从源服务器上**过来的表映射文件；

TARGETDB LIBFILE即定义kafka一些适配性的库文件以及配置文件，配置文件位于OGG主目录下的dirprm/kafka.props；

REPORTCOUNT即**任务的报告生成频率；

GROUPTRANSOPS为以事务传输时，事务合并的单位，减少IO**作；

MAP即源端与目标端的映射关系

6.5 配置文件kafka.props

注意：配置时需要将注释删除不然会报错！！！

root@test01 ~]# cd /u01/ogg12.3/dirprm 编辑kafka.props

[root@test01 dirprm]# vi kafka.props

gg.handlerlist=kafkahandler //handler类型

gg.handler.kafkahandler.type=kafka

gg.handler.kafkahandler.KafkaProducerConfigFile=custom_kafka_producer.properties //kafka相关配置

gg.handler.kafkahandler.topicMappingTemplate=test_ogg //kafka的topic名称，无需手动创建

gg.handler.kafkahandler.format=json //传输文件的格式，支持json，xml等

gg.handler.kafkahandler.mode=op //OGG for Big Data中传输模式，即op为一次SQL传输一次，tx为一次事务传输一次

##gg.classpath=dirprm/:/u01/ogg12.3/:/u01/ogg12.3/lib/*

一定要有kafka安装的库文件，不然会一直报错

gg.classpath=dirprm/:/u01/ogg12.3/*:/u01/ogg12.3/lib/*:/u01/ogg12.3/ggjava/resources/lib/*:/usr/local/kafka_2.13-2.7.0/libs/*

6.6 编辑文件custom_kafka_producer.properties

注意：配置时需要将注释删除

[root@test01 dirprm]#vi custom_kafka_producer.properties

bootstrap.servers=192.168.141.107:9092 //kafkabroker的地址

acks=1

compression.type=gzip //压缩类型

value.serializer=org.apache.kafka.common.serialization.ByteArraySerializer

key.serializer=org.apache.kafka.common.serialization.ByteArraySerializer

batch.size=102400

linger.ms=10000

6.7 添加trail文件到replicate进程

GGSCI (test01) 14>add replicat rekafka exttrail ./dirdat/pa,checkpointtable ggusr.checkpoint

7. 测试7.1 启动相关进程并检查

源端启动mgr ，extkafka, pukafka

Start mgr

Start extkafka

Start pukafka

GGSCI (oracle01) 1> info all

Program Status Group Lag at Chkpt Time Since Chkpt

MANAGER RUNNING

EXTRACT RUNNING EXTKAFKA 00:00:00 00:00:06

EXTRACT RUNNING PUKAFKA 00:00:00 00:00:00

目标端启动mgr rekafka

Start mgr

Start rekafka

GGSCI (test01) 1> info all

Program Status Group Lag at Chkpt Time Since Chkpt

MANAGER RUNNING

REPLICAT RUNNING REKAFKA 00:00:00 00:00:07

7.2 数据插入，更改，和删除测试

在源端数据上，使用scott用户对表test_ogg做insert，update，delete**作

insert into test_ogg values(1,'test');

commit;

update test_ogg set name='zhangsan' where id=1;

commit;

delete from test_ogg where id=1;

Commit;

目标端查看topics是否创建：

./kafka-topics.sh –list –zookeeper 192.168.141.107:2181

[root@test01 bin]# ./kafka-topics.sh –list –zookeeper 192.168.141.107:2181

test_ogg —文件中定义的名字，出现说明同步正常

通过消费者查看数据是否同步：

启动kafka消费者，会在前台挂起一个实时进程，第二在源端对表进程**作，会实时显示在消费者端！！！

[root@test01 bin]# ./kafka-console-consumer.sh –bootstrap-server 192.168.141.107:9092 –topic test_ogg –from-beginning

{"table":"SCOTT.TEST_OGG","op_type":"I","op_ts":"2021-03-10 12:27:13.417910","current_ts":"2021-03-10T12:27:20.018000","pos":"00000000000000001817","after":{"ID":1,"NAME":"test"}}

正常同步到Kafka,格式为json,

其中op_type代表**作类型，可配置或者使用默认的配置：

gg.handler.kafkahandler.format.insertOpKey = I

gg.handler.kafkahandler.format.updateOpKey = U

gg.handler.kafkahandler.format.deleteOpKey = D

before代表**作之前的数据，after代表**作后的数据!!
