1. 测试环境：

源端：

OS：Centos 6.8

数据库：11.2.0.4

实例： rac1 rac2 rac3

Goldengate：fbo_ggs_Linux_x64_shiphome.zip

Rac与单实例不同之处在于rac上的goldengate 需要安装在共享存储上

目的端：

OS：Centos 6.8

数据库：11.2.0.4 　

实例：test

2. 源端配置步骤

1) 配置ACFS，

具体的可参考：http://blog.csdn.net/shiyu1157758655/article/details/62215468

这里就直接用asmca 进行创建（也可以用命令进行操作）

[root@rac1 ~]# su - grid

+ASM1:/home/grid@rac1>export DISPLAY=192.168.180.186:0.0

+ASM1:/home/grid@rac1>asmca

这里已经创建数据磁盘组的名字为“ACFS”，这里就省略创建磁盘组的步骤

磁盘组创建完成后，再点击Volumes标签页，创建卷：

卷创建完成后，为该卷创建ACFS文件系统，点击ASM Cluster File System：

至此ACFS就创建完了

在各个节点查看是否挂载上：

2）下载安装ogg

下载可以直接到Oracle 官网上下载即可

将下载好的ogg安装包上传到刚才建立的/ogg 共享磁盘下

注意这里我们将以oracle用户安装（之前测试用grid安装，遇到P进程起不来，也没找到好的方法解决）

rac1:/ogg@rac1>unzip fbo_ggs_Linux_x64_shiphome.zip

rac1:/home/oracle@rac1>cd /ogg/

rac1:/ogg@rac1>cd fbo_ggs_Linux_x64_shiphome/Disk1/

rac1:/ogg/fbo_ggs_Linux_x64_shiphome/Disk1@rac1>exportDISPLAY=192.168.180.186:0.0

rac1:/ogg/fbo_ggs_Linux_x64_shiphome/Disk1@rac1>./runInstaller

Preparing to launch Oracle Universal Installer from/tmp/OraInstall2017-03-12_12-59-46PM. Please wait ...

注意这里提示我的/ogg/install 下不为空，可以直接选择忽略就可以了，不会有影响的

安装好以后，进入ogg安装目录执行：ggsci

rac1:/ogg@rac1>cd /ogg/install/

rac1:/ogg/install@rac1>./ggsci

OracleGoldenGate Command Interpreter for Oracle

Version12.2.0.1.1 OGGCORE_12.2.0.1.0_PLATFORMS_151211.1401_FBO

Linux,x64, 64bit (optimized), Oracle 11g on Dec 12 2015 00:54:38

Operatingsystem character set identified as UTF-8.

GGSCI (rac1) 1>

注意这里一定配置: LD_LIBRARY_PATH,否则会报以下的错误：

/ggsci ./ggsci: error while loading shared libraries: libnnz11.so:cannot open shared object file: No such file or directory

只要在.bash_profile 里设置LD_LIBRARY_PATH就行了，如下：

exportLD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/lib32/:/usr/lib:/usr/lib64:/usr/local/lib:/lib:/lib64

3）开启DB归档以及最小附加日志（在其中任意一个节点上执行就可以了）

rac1:/home/oracle@rac1>sqlplus/ as sysdba

SQL> altersystem set enable_goldengate_replication = true scope=both;

注意：这里要重启数据库，使参数生效

4）创建表空间以及用户（在其中任意一个节点上执行）

rac1:/home/oracle@rac1>sqlplus/ as sysdba

SQL*Plus:Release 11.2.0.4.0 Production on Sat Mar 11 09:18:58 2017

Grant succeeded.

SQL> grant update on sys.streams$_capture_process to ogg;

Grant succeeded.

SQL> grant becomeuser to ogg;

Grant succeeded.

SQL> grant flashback any table to ogg;

Grant succeeded.

注意：红色标记的可以不用执行，

5）配置TNS（各节点都要执行）

RAC =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = rac-scan)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = rac)

)

ASM =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.180.2)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = +ASM)

(SID_NAME = +ASM1)

)

6）安装ddl同步支持

rac1:/home/oracle@rac1>cd /ogg/install/ --进入ogg安装目录

rac1:/ogg/install@rac1>sqlplus/ as sysdba

安装性能优化工具 (可选项)

要提高DDL触发器的性能，可以通过ddl_pin脚本，该脚本会将触发器使用的包加载到内存，以此提高效率。该脚本执行时需要引用dbms_shared_pool系统包，因此在使用ddl_pin脚本前需要确保dbms_shared_pool可用。

执行ddl_pin脚本需要指定GoldenGate管理员schema名称，例如：

SQL>@ddl_pin ogg

PL/SQLprocedure successfully completed.

7) 开启表级别、日志传输，创建检查点表

开启归档，最小附加日志和强制归档之后，ogg可以同步insert，delete等部分操作，但遇到update 时将会挂掉，报错说找不到相关记录，因此，还需要再对每一个table都在源端开启表级日志传输。（必须要登陆ogg才可以执行）

rac1:/home/oracle@rac1>cd/ogg/install/

rac1:/ogg/install@rac1>./ggsci

OracleGoldenGate Command Interpreter for Oracle

Loggingof supplemental redo log data is already enabled for table TEST.TEST.

TRANDATA for instantiation CSN has been added on table'TEST.TEST'.

注意：这里只是做测试，就只有一张test的表，如果有其他的表，都要执行。

再执行如下命令创建检查点表

GGSCI (oracle11g as ogg@test)118> add checkpointtable ogg.chkpt

Successfully created checkpointtable ogg.chkpt.

8）配置OGG 进程

rac1:/ogg/install@rac1>./ggsci

Oracle GoldenGate CommandInterpreter for Oracle

Version 12.2.0.1.1OGGCORE_12.2.0.1.0_PLATFORMS_151211.1401_FBO

PURGEOLDEXTRACTS/ogg/install/replt/rac/lt*,USECHECKPOINTS, MINKEEPDAYS 7

里面添加上面的内容

添加抽取进程：

GGSCI (rac1 as ogg@rac1)4> add extract E_RAC,tranlog,threads 3 begin now

EXTRACT added.

GGSCI (rac1 as ogg@rac1) 6> add exttrail /ogg/install/dirdat/extlt/rac/lt,extract E_RAC

EXTTRAIL added.

配置E_RAC参数文件

GGSCI (rac1 as ogg@rac1)7> edit params E_RAC

EXTRACT E_RAC

SETENV (ORACLE_HOME ="/u01/app/oracle/product/11.2.0/db_1")

OBEY /ogg/install/dirprm/ogg_tables_RAC.txt --载入所要抽取的table list；里面内容为: table TEST.TEST;

添加传送到目标端的p进程 P_TEST

注意关于目的端ogg和RAC安装一样，按上面的操作在目标端安装ogg，这里就不再赘述。

GGSCI (rac1 as ogg@rac1) 9> add extract P_TEST,exttrailsource /ogg/install/dirdat/extlt/rac/lt

EXTRACT added.

GGSCI (rac1 as ogg@rac1)10> add rmttrail /ogg/dirdat/replt/rac/lt, extract P_TEST

配置P_TEST的参数文件

GGSCI (rac1 as ogg@rac1) 13> edit paramsP_TEST

EXTRACT P_TEST

rmthost 192.168.180.14, mgrport 7809 --目的端的IP

rmttrail /ogg/dirdat/replt/rac/lt --trail文件传送过去的存放路径

dynamicresolution --动态解析表名，为缺省参数，可不显示指定

passthru --使用该参数告诉ogg同步的两端表结构一致

OBEY /ogg/install/dirprm/ogg_tables_RAC.txt --载入所要传送的table list，和上面的同一个

3. 目的端操作：

关于目的端ogg的安装可以参考上述步骤，这里不在赘述。以下是几个注意点

1) 开启归档，最小附件日志

2) 创建表空间及授权

3) 配置TNS

4) 安装ddl同步支持

5) 开启表级日志传输（如果是单向的就不要执行）

6) 创建检查点表

7) 执行alter system set enable_goldengate_replication = true scope=both;

目标端安装完ogg之后，开始配置ogg进程

test:/ogg@oracle11g>cd/ogg/ --这里ogg安装目录为/ogg

test:/ogg@oracle11g>./ggsci

OracleGoldenGate Command Interpreter for Oracle

添加rep进程R_RAC

GGSCI (oracle11gas ogg@test) 63> add replicat R_RAC, exttrail/ogg/dirdat/replt/rac/lt,checkpointtable ogg.chkpt

配置R_RAC 的参数文件

GGSCI (oracle11g) 2> edit paramsR_RAC

OBEY /ogg/dirprm/ogg_tables_RAC_REP.txt –该里面的内容为：map TEST.TEST,target TEST.TEST;

GGSCI (oracle11g) 3>

以上配置结束执行，依次开启刚才配置的E_RAC,P_TEST,R_RAC三个进程

源端开启E_RAC,P_TEST进程：

GGSCI (rac1 as ogg@rac1) 16> start E_RAC

Sending START request to MANAGER ...

EXTRACT E_RAC starting

GGSCI(rac1) 27> start P_TEST

SendingSTART request to MANAGER ...

EXTRACT P_TEST starting

目的端开启R_RAC 进程

GGSCI (oracle11g as ogg@test) 82> start R_RAC

Sending START request to MANAGER ...

REPLICAT R_RAC starting

4. 测试

在源端3个节点分别在test里插入一笔数据

注意：这里要在目的端也要有相同结构的test表

节点1：

SQL> insert into test.testvalues(1,'rac1');

1 row created.

SQL> commit;

Commit complete

节点2：

SQL> insert into test.test values(2,'rac2');

1 row created.

SQL> commit;

Commit complete

节点3：

SQL> insert into test.test values(3,'rac3');

1 row created.

SQL> commit;

Commit complete

再目的端查看：

test:/ogg/dirdat/replt/rac@oracle11g>sqlplus/ as sysdba
