oracle使用ogg导出数据到kafka

前提

环境

oracle 19c   10.0.2.15  
kafka  kafka_2.13-2.8.0 二进制安装   10.0.2.12

安装包

oracle源端

191004_fbo_ggs_Linux_x64_shiphome.zip

kafka目标端

OGG_BigData_Linux_x64_19.1.0.0.5.tar.gz
kafka_2.13-2.8.0.tgz

oracle源端操作

安装ogg

创建ogg目录，解压安装包，root用户操作

mkdir -p /ogg
任意目录下解压，这里解压到了/home/oracle/目录
unzip 191004_fbo_ggs_Linux_x64_shiphome.zip -d /home/oracle/

授权root用户操作

chown -R oracle.oinstall /home/oracle/fbo_ggs_Linux_x64_shiphome/

编辑安装应答文件

cat  /home/oracle/fbo_ggs_Linux_x64_shiphome/Disk1/response/oggcore.rsp

GGSCI (localhost.localdomain) 1> dblogin userid ogg password ogg
Successfully logged into database.
GGSCI (localhost.localdomain as ogg@orcl) 2> edit param ./globals

配置mgr进程

GGSCI (localhost.localdomain as ogg@orcl) 3> edit param mgr


PORT 7809
DYNAMICPORTLIST 7810-7909
AUTORESTART EXTRACT *,RETRIES 5,WAITMINUTES 3
PURGEOLDEXTRACTS ./dirdat/*,usecheckpoints, minkeepdays 3

说明：

PORT               即mgr的默认监听端口；
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

GGSCI (localhost.localdomain as ogg@orcl) 4> add trandata test_ogg.test_ogg

2021-05-24 16:46:11  INFO    OGG-15131  Logging of supplemental redo log data is already enabled for table TEST_OGG.TEST_OGG.

Prepared CSN for table TEST_OGG.TEST_OGG: 3094843

配置extract进程

GGSCI (localhost.localdomain as ogg@orcl) 6> edit param extkafka


extract extkafka
dynamicresolution
SETENV (ORACLE_SID = "orcl")
SETENV (NLS_LANG = "american_america.AL32UTF8")
userid ogg,password ogg
exttrail /ogg/dirdat/to
table test_ogg.test_ogg;

说明：

第一行指定extract进程名称；
dynamicresolution          动态解析；
SETENV                     设置环境变量，这里分别设置了Oracle数据库以及字符集；
userid ggs,password ggs    即OGG连接Oracle数据库的帐号密码，这里使用2.5中特意创建的复制帐号；
exttrail                   定义trail文件的保存位置以及文件名，注意这里文件名只能是2个字母，其余部分OGG会补齐；
table                      即复制表的表名，支持*通配，必须以;结尾

添加extract进程：

GGSCI (localhost.localdomain as ogg@orcl) 7> add extract extkafka,tranlog,begin now

添加trail文件的定义与extract进程绑定

GGSCI (localhost.localdomain as ogg@orcl) 8> add exttrail /opt/ogg/dirdat/to,extract extkafka

配置pump进程

pump进程负责把trail文件传送到目标端

GGSCI (localhost.localdomain as ogg@orcl) 9> edit param pukafka


extract pukafka
passthru
dynamicresolution
userid ogg,password ogg
rmthost 10.0.2.12 mgrport 7809
rmttrail /opt/ogg/dirdat/to
table test_ogg.test_ogg;

说明：

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服务的地址以及监听端口；
rmttrail                  即目标端trail文件存储位置以及名称。

分别将本地trail文件和目标端的trail文件绑定到extract进程：

GGSCI (localhost.localdomain as ogg@orcl) 10> add extract pukafka,exttrailsource /ogg/dirdat/to
GGSCI (localhost.localdomain as ogg@orcl) 11> add rmttrail /opt/ogg/dirdat/to,extract pukafka

配置define文件

GGSCI (localhost.localdomain as ogg@orcl) 12> edit param test_ogg


defsfile /ogg/dirdef/test_ogg.test_ogg
userid ogg,password ogg
table test_ogg.test_ogg;

[oracle@localhost ogg]$ cd /ogg/
[oracle@localhost ogg]$ ./defgen paramfile dirprm/test_ogg.prm

将生成的/opt/ogg/dirdef/test_ogg.test_ogg发送的目标端ogg目录下的dirdef里：

[oracle@localhost ogg]$ scp -r /ogg/dirdef/test_ogg.test_ogg [email protected]:/opt/ogg/dirdef/ 

OGG目标端配置

前提kafka服务开启

配置管理器mgr

[root@localhost ogg]# cd /opt/ogg/
[root@localhost ogg]# ggsci

GGSCI (localhost.localdomain) 1> edit param mgr


PORT 7809
DYNAMICPORTLIST 7810-7909
AUTORESTART EXTRACT *,RETRIES 5,WAITMINUTES 3
PURGEOLDEXTRACTS ./dirdat/*,usecheckpoints, minkeepdays 3

配置checkpoint

checkpoint即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 (localhost.localdomain) 2> edit  param  ./GLOBALS


CHECKPOINTTABLE test_ogg.checkpoint

配置replicate进程

GGSCI (localhost.localdomain) 3> edit param rekafka


REPLICAT rekafka
sourcedefs /opt/ogg/dirdef/test_ogg.test_ogg
TARGETDB LIBFILE libggjava.so SET property=dirprm/kafka.props
REPORTCOUNT EVERY 1 MINUTES, RATE
GROUPTRANSOPS 10000
MAP test_ogg.test_ogg, TARGET test_ogg.test_ogg;

说明：

REPLICATE rekafka    定义 rep进程名称；
sourcedefs           即在4.6中在源服务器上做的表映射文件；
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          即复制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操作；
MAP                  即源端与目标端的映射关系

配置kafka.props

cd /opt/ogg/dirprm/
vim kafka.props

[root@localhost ogg]# cd /opt/ogg/dirprm/
[root@localhost dirprm]# cat kafka.props 
gg.handlerlist=kafkahandler
gg.handler.kafkahandler.type=kafka
gg.handler.kafkahandler.KafkaProducerConfigFile=custom_kafka_producer.properties 
gg.handler.kafkahandler.topicMappingTemplate=test_ogg 
gg.handler.kafkahandler.format=json
gg.handler.kafkahandler.mode=op  
gg.classpath=dirprm/:/opt/kafka_2.13-2.8.0/libs/*:/opt/ogg/:/opt/ogg/lib/*

[root@localhost ogg]# cd /opt/ogg/dirprm/
[root@localhost dirprm]# cat 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

其中需要将后面的注释去掉，ogg不识别注释，如果不去掉会报错
