测试目的:

ORACLE ACTIVE DATAGUARD 作为数据抽取源,使用ORACLE GOLDENGATEORACLE数据库中变化数据同步到HBASE集群。

 

一.部署ORACLE RACACTIVE DATAGUARD

  请参照之前ADG EXAMPLE 文档

 

二.在主库RAC上的准备工作

 

1. 创建GoldenGate表空间

2. 创建GoldenGate用户并授权

3. 开启force logging(做Active Datagurad时候已经配好)

4. 启用附加日志

alter database add supplemental log data;

alter system switch logfile;

select supplemental_log_data_min from v$database;

5. 启用enable_goldengate_replication

alter system set enable_goldengate_replication=true;

 

三.ADG上部署goldengate 12.2

1. 创建golden os用户

 

2. 创建ogg软件安装目录 /goldengate/gg12c

 

3. 编辑golden用户profile

Vi .bash_profile 添加如下内容:

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1

export ORACLE_SID=uatracdg  --ACTIVE DATAGUARD ORACLE SID

export LD_LIBRARY_PATH=/goldengate/gg12c:$ORACLE_HOME/lib:$ORACLE_HOME/lib32

export OGG_HOME=/goldengate/gg12c

PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin:/goldengate/gg12c:.

export PATH

cd $OGG_HOME

 

4. 下载goldengate 12.2 for linux 64bit版本

最新软件包名 V100692-01.zip

 

5. 解压安装包

Unzip V100692-01.zip得到下列文件:

fbo_ggs_Linux_x64_shiphome

OGG-12.2.0.1.1-ReleaseNotes.pdf  

OGG-12.2.0.1-README.txt

 

6. 编辑静默安装参数文件

cd /goldengate/fbo_ggs_Linux_x64_shiphome/Disk1/response

编辑response文件,更改下列参数

INSTALL_OPTION=ORA11g

SOFTWARE_LOCATION=/goldengate/gg12c

START_MANAGER=true

MANAGER_PORT=7801

DATABASE_LOCATION=/u01/app/oracle/product/11.2.0/dbhome_1

INVENTORY_LOCATION=/goldengate/gg12c/oraInventory

UNIX_GROUP_NAME=oinstall

 

7. 静默安装OGG

cd /goldengate/fbo_ggs_Linux_x64_shiphome/Disk1

./runInstaller -silent -responseFile /goldengate/fbo_ggs_Linux_x64_shiphome/Disk1/response/oggcore.rsp

 

8.  添加表的附加日志

因为ADG是只读模式,添加附加日志需要更改数据字典,所以此操作需要在ggsci命令行中连接主库RAC进行

ggsci dblogin userid goldengate@uatrac passowrd

add trandata HADP.OGGT1

add trandata HADP.OGGT2

 

9.  添加配置extract进程

add extract ext01, tranlog, begin yyyy-MM-dd HH:mm:ss

add exttrail ./dirdat/et, extract ext01

edit param ext01

EXTRACT ext01

setenv ( NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK" )

setenv ( ORACLE_SID=uatracdg )

userid goldengate, password golden123

exttrail ./dirdat/et

gettruncates

--dynamicresolution

discardfile ./dirrpt/discardext01.txt, append, megabytes 50

--DBOPTIONS ALLOWUNUSEDCOLUMN

--TRANLOGOPTIONS CONVERTUCS2CLOBS

EOFDELAY 3

getupdatebefores

TRANLOGOPTIONS MINEFROMACTIVEDG --FOR ADG

TABLE HADP.OGGT2;

TABLE HADP.OGGT1;

10.  添加配置PUMP进程

add extract pup1, exttrailsource ./dirdat/et

add rmttrail ./dirdat/rt, extract pup1

Edit param pup1

extract pup1

setenv ( NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK" )

userid goldengate password golden123

rmthost 172.16.49.35, mgrport 7809, TCPBUFSIZE 5000000

rmttrail ./dirdat/rt

DYNAMICRESOLUTION

NUMFILES 3000

ALLOCFILES 200

passthru

TABLE HADP.OGGT2;

TABLE HADP.OGGT1;

 

 

四.CDH上部署goldengate for big data 12.2

1. 创建golden os用户

2. 创建ogg软件安装目录 /goldengate/gg12c

3. 编辑golden用户profile

export JAVA_HOME=/usr/local/jdk1.7.0_80

PATH=$PATH:$HOME/bin

export PATH

export NLS_LANG=AMERICAN_AMERICA.ZHS16BGK

export PATH=$JAVA_HOME/bin:$PATH:/goldengate/gg12c:/usr/local/apache-maven-3.1.1/bin:.

export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/amd64/server:/goldengate/gg12c:/goldengate/gg12c/ggjava/resources/ggplugins/hdfs:.

export CLASSPATH=/goldengate/gg12c/ggjava/*:/goldengate/gg12c/dirprm/*:/goldengate/gg12c/lib/*:/etc/hadoop/conf/core-site.xml:/etc/hadoop/conf/hdfs-site.xml:/opt/cloudera/parcels/

CDH-5.6.0-1.cdh5.6.0.p0.45/lib/hadoop-hdfs/*:/opt/cloudera/parcels/CDH-5.6.0-1.cdh5.6.0.p0.45/lib/hadoop-hdfs/lib/*:/opt/cloudera/parcels/CDH-5.6.0-1.cdh5.6.0.p0.45/lib/hadoop/*:/

opt/cloudera/parcels/CDH-5.6.0-1.cdh5.6.0.p0.45/lib/hadoop/client/*:/goldengate/gg12c/dirprm/*:/opt/cloudera/parcels/CDH-5.6.0-1.cdh5.6.0.p0.45/lib/hadoop/lib/*:.

export OGG_HOME=/goldengate/gg12c

4.下载ogg for big data

最新软件包V100447-01.zip

5.安装ogg for big data

解压在安装目录即可

6.创建子目录

Ggsci > create subdirs

7.配置管理进程MGR

Edit param mgr

PORT 7809

dynamicportlist 7820-7850

8.添加配置复制进程

/goldengate/gg12c/AdapterExamples/big-data/hbase下文件copy$OGG_HOME/dirprm下,

编辑hbase.props

更改下列参数

gg.handler.hbase.hBaseColumnFamilyName=ID

gg.classpath=/etc/hbase/conf.cloudera.hbase:/opt/cloudera/parcels/CDH-5.6.0-1.cdh5.6.0.p0.45/lib/hbase/*:/opt/cloudera/parcels/CDH-5.6.0-1.cdh5.6.0.p0.45/lib/hbase/lib/*:/opt/cloudera/parcels/CDH-5.6.0-1.cdh5.6.0.p0.45/lib/hadoop/*:/opt/cloudera/parcels/CDH-5.6.0-1.cdh5.6.0.p0.45/lib/hadoop/client/*:/goldengate/gg12c/dirprm/*:/opt/cloudera/parcels/CDH-5.6.0-1.cdh5.6.0.p0.45/lib/hadoop/lib/*:.

 

ggsci>add replicat rhbase, nodbcheckpoint, exttrail ./dirdat/rt

ggsci>Edit param rhbase

REPLICAT rhbase

SOURCEDEFS ./dirsql/hdfs.sql

-- Trail file for this example is located in "AdapterExamples/trail" directory

-- Command to add REPLICAT

-- add replicat rhbase, exttrail AdapterExamples/trail/tr

setenv (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)

TARGETDB LIBFILE /goldengate/gg12c/libggjava.so SET property=/goldengate/gg12c/dirprm/hbase.props

REPORTCOUNT EVERY 1 MINUTES, RATE

GROUPTRANSOPS 10000

MAP HADP.OGGT2, TARGET HADP.OGGTEST,

RESOLVECONFLICT(INSERTROWEXISTS, (DEFAULT, OVERWRITE)),

COLMAP (ID=ID, COL1=COL1, COL2=COL2);

MAP HADP.OGGT1, TARGET HADP.OGGTEST,

RESOLVECONFLICT(INSERTROWEXISTS, (DEFAULT, OVERWRITE)),

COLMAP (ID=ID, COLA=COLA, COLB=COLB);

9.登陆HBASE创建测试表

创建namespace HADP

hbase shell

create namespace ‘HADP’

list_namespace

describe_namespace ‘HADP’

创建表:

create ‘HADP:OGGTEST’,’ID’,’COL1’,’COL2’,’COLA’,’COLB’

查看表数据:

scan ‘HADP:OGGTEST’

10.查看OGG FOR BIG DATA日志

cd /goldengate/gg12c/dirrpt

more *hbase*.log
