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

##关闭回收站
SQL> SHOW PARAMETER recyclebin;

SQL> show recyclebin;

---------------- ------------------------------ ------------ -------------------
IMAGE_LOB BIN$CWQtAJlQCH3gYx4MEqylGQ==$0 TABLE 2023-11-05:08:03:41
SQL> PURGE recyclebin;
✨ 2.2 新增用户
-- OGG管理用户
CREATE USER ogg identified by oracle;
GRANT DBA to ogg;
grant SELECT ANY DICTIONARY to ogg;
GRANT EXECUTE ON SYS.DBMS_LOCK TO ogg;
grant select any transaction to ogg;
grant select any table to ogg;
grant flashback any table to ogg;
grant alter any table to ogg;
-- 业务用户
CREATE USER rptuser identified by oracle;
alter user sys identified by oracle;
GRANT DBA to rptuser ;
grant SELECT ANY DICTIONARY to rptuser;
GRANT EXECUTE ON SYS.DBMS_LOCK TO rptuser;
-- 启动监听
[oracle@jemora11204 ~]$ 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

tcp 0 0 127.0.0.1:2181 127.0.0.1:57458 TIME_WAIT
[root@kafka /]# netstat -tna|grep -e 9092 -e 2181

[root@kafka /]# jps

[root@kafka /]# netstat -tulnp | grep java

tcp 0 0 0.0.0.0:43337 0.0.0.0:* LISTEN 443/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
✨ 4.2 添加表附加日志
dblogin useridalias ora11g
ADD SCHEMATRANDATA RPTUSER
INFO SCHEMATRANDATA RPTUSER
list tables RPTUSER.*
✨ 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
📣 7.Kafka确认
#查看主题
cd /usr/local/kafka/kafka_2.13-3.5.1
./bin/kafka-topics.sh --list --bootstrap-server localhost:9092
[root@kafka kafka_2.13-3.5.1]# ./bin/kafka-topics.sh --list --bootstrap-server localhost:9092
