前言

近期给客户实施大数据，本文详细阐述了将Oracle全量同步到kafka的过程

📣 1.部署环境

✨ 1.1 架构规划

![在这里插入图片描述]()

✨ 1.2 服务规划

主机名	IP	操作系统	内存/空间	角色	说明
ora11204	172.18.12.30	centos7.8	2c/18G 400G	源端	Oracle 11GR2 (11.2.0.4)
kafka	172.18.12.31	centos7.8	2c/18G 400G	大数据平台	kafka3.5.0
ogg21all	172.18.12.32	centos7.8	2c/18G 400G	OGG	OGG for Oracle/bigdata
dbbench	172.18.12.33	centos7.8	2c/18G 400G	压力测试	sysbench 1.0.17

📣 2.Oracle相关配置

✨ 2.1 参数调整

-- oracle数据库配置
1.开启数据库归档--如果没有开启
2.开启数据库级别附加日志--如果没有开始最小附加日志
3.开启强制日志--如果没有开启强制日志
4.设置ENABLE_GOLDENGATE_REPLICAT参数为TRUE
5.创建OGG用户包括包括源端用户、目标端用户以及OGG抽取用户


alter database add supplemental log data;
alter database add supplemental log data (all) columns;
alter database force logging;
alter system set enable_goldengate_replication=TRUE;

##开归档

mkdir -p /u01/app/oracle/arch 

SYS@JEM11GR2> shutdown immediate;

Database dismounted.
ORACLE instance shut down.
SYS@JEM11GR2> startup mount;

✨ 2.2 新增用户

-- OGG管理用户
CREATE USER ogg identified by oracle;
GRANT DBA to ogg;
grant SELECT ANY DICTIONARY to ogg;
GRANT EXECUTE ON SYS.DBMS_LOCK TO ogg;
grant select any transaction to ogg;
grant select any table to ogg;
grant flashback any table to ogg;
grant alter any table to ogg;

-- 业务用户
CREATE USER rptuser identified by oracle;
alter user sys identified by oracle;
GRANT DBA to rptuser ;
grant SELECT ANY DICTIONARY to rptuser;
GRANT EXECUTE ON SYS.DBMS_LOCK TO rptuser;


-- 启动监听
[oracle@jemora11204 ~]$ lsnrctl start
[oracle@jemora11204 ~]$ lsnrctl status

📣 3.kafka环境

1.启动进程
/usr/local/kafka/kafka_2.13-3.5.1/bin/zookeeper-server-start.sh -daemon /usr/local/kafka/kafka_2.13-3.5.1/config/zookeeper.properties
/usr/local/kafka/kafka_2.13-3.5.1/bin/kafka-server-start.sh -daemon /usr/local/kafka/kafka_2.13-3.5.1/config/server.properties

[root@kafka /]# netstat -nta|grep 2181

[root@kafka /]# jps

[root@kafka /]# netstat -tulnp | grep java
tcp        0      0 0.0.0.0:9092            0.0.0.0:*               LISTEN      2231/java

kafka默认占用9092端口，ZK默认占用2181端口。

2.kafka日志
/usr/local/kafka/kafka_2.13-3.5.1/kafka_log


3.测试kafka
#创建主题
cd /usr/local/kafka/kafka_2.13-3.5.1
./bin/kafka-topics.sh --bootstrap-server localhost:9092 --create --topic topic --partitions 1
其中--partitions 参数指定分区数。在实际生产环境中，建议将副本数设置为 2 或 3，以提高可用性。

#查看主题
./bin/kafka-topics.sh --list --bootstrap-server localhost:9092

##发送消息
./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic topic
>hello
>world

##接收消息
./bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic topic --from-beginning
hello
world

📣 4.OGG for Oracle

✨ 4.1 创建身份证明

1.测试登录
sqlplus ogg/oracle@172.18.12.30:1521/JEM11GR2

2.创建身份
su - oracle
ogg
add credentialstore
alter credentialstore add user ogg@172.18.12.30/JEM11GR2, password oracle alias ora11g
INFO CREDENTIALSTORE
dblogin useridalias ora11g

OGG将Oracle全量同步到kafka_kafka

✨ 4.2 添加表附加日志

dblogin useridalias ora11g
ADD SCHEMATRANDATA RPTUSER
INFO SCHEMATRANDATA RPTUSER
list tables RPTUSER.*

OGG将Oracle全量同步到kafka_原力计划_02

✨ 4.3 进程配置

– oracle端
edit params exta

EXTRACT exta
USERIDALIAS ora11g
rmthost 127.0.0.1,mgrport 8809
rmttask replicat,group exta
tableexclude RPTUSER.PRODUCTS;
tableexclude RPTUSER.PRODUCT_PRICES;
TABLE RPTUSER.*;

– 启动mgr
start mgr

GGSCI (ogg21all) 4> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
JAGENT STOPPED
PMSRVR STOPPED

📣 5.OGG for Bigdata

✨ 5.1 配置主进程

su - bigdata
ogg

edit params mgr
port 8809
ACCESSRULE, PROG *, IPADDR *, ALLOW

GGSCI (ogg21all) 1> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER STOPPED

✨5.2 kafka端配置

su - bigdata
ogg
edit params repa

REPLICAT repa
targetdb libfile libggjava.so set property=./dirprm/kafka.props
REPLACEBADCHAR SKIP
SOURCECHARSET OVERRIDE GBK
map RPTUSER., target RPTUSER.;

– 配置kafka参数
vi /oggbigdata/dirprm/kafka.props
gg.handler.kafkahandler.schemaTopicName=ORA_OGG

vi /oggbigdata/dirprm/custom_kafka_producer.properties
bootstrap.servers=172.18.12.31:9092

📣 6.全量同步

注意：在此阶段，源端需要停业务，不能产生新数据。
start exta
info exta
view report exta

OGG将Oracle全量同步到kafka_数据库_03

📣 7.Kafka确认
