GoldenGate的安装与配置(一)oracle——oracle单向复制（DML和DDL）

测试环境：

OS： Redhat 6.3 64bit

[root@orcl1 ~]# uname -a
Linux orcl1 2.6.32-279.el6.x86_64 #1 SMP Wed Jun 13 18:24:36 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux

DB: Oracle 11.2.0.4 64bit

SQL> select * from v$version where rownum=1;
BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

以下操作在源库和目标库都要执行

安装GoldenGate软件

1.1解压安装 

[oracle@orcl1 ~]$ mkdir -p /u01/ggate/

[oracle@orcl1 ggate]$ cd /u01/ggate/
[oracle@orcl1 ggate]$ unzip ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip 

[oracle@orcl1 ggate]$ tar xvf fbo_ggs_Linux_x64_ora11g_64bit.tar 

1.2添加环境变量

在/home/oracle/.bash_profile文件里添加如下内容：

export PATH=/u01/ggate:$PATH

export LD_LIBRARY_PATH=/u01/ggate:$LD_LIBRARY_PATH

export GGATE=/u01/ggate

1.3 创建源端和目标端ogg目录

[oracle@orcl1 ggate]$ ggsci 

Oracle GoldenGate Command Interpreter for Oracle

     Version 11.2.1.0.1 OGGCORE_11.2.1.0.1_PLATFORMS_120423.0230_FB

     Linux, x64, 64bit (optimized), Oracle 11g on Apr 23 2012 08:32:14

      GGSCI (orcl1) 1> create subdirs 

Creating subdirectories under current directory /u01/ggate

    Parameter files                 /u01/ggate/dirprm: already exists

   Report files                    /u01/ggate/dirrpt: created

   Checkpoint files                /u01/ggate/dirchk: created

   Process status files            /u01/ggate/dirpcs: created

    SQL script. files                /u01/ggate/dirsql: created

    Database definitions files      /u01/ggate/dirdef: created

   Extract data files              /u01/ggate/dirdat: created

    Temporary files                /u01/ggate/dirtmp: created

    Stdout files                    /u01/ggate/dirout: created

配置goldengate

2.1 归档模式、附加日志、强制日志

SQL> select log_mode,supplemental_log_data_min,force_logging from v$database;

LOG_MODE     SUPPLEME FOR

------------ -------- ---

ARCHIVELOG  NO       NO

（1）archivelog

SQL>shutdown immediate

SQL>startup mount

SQL>alter database archivelog;

SQL>alter database open;

（2） force logging

SQL>alterdatabase force logging;

（3）supplemental log data

SQL>alterdatabase add supplemental log data;

如果启用DDL 支持，必须关闭recycle bin

Oracle 11g：

SQL> alter system set recyclebin=off scope=spfile;

System altered.

2.2 创建存放DDL 信息的user并赋权

SQL> create user ggate identified by ggate default tablespace users temporary tablespace temp;

User created.

      grant connect,resource to ggate;
      grant execute on utl_file to ggate;
     GRANT CREATE TABLE,CREATE SEQUENCE TO ggate;---如果没有此权限，会报错

2.3 进入GGATE目录，以sysdba用户执行脚本（/u0/ggate/）：

@maker_setup.sql-------ddl_setup.sql-------role_setup.sql------grant GGS_GGSUSER_ROLE to ggate;-----@ddl_enable.setup.sql

2.4 （ 配置源和目标两端tnsnames，保持互联互通。

测试goldengate  

3.1在Source 和Target 上配置Manager

GGSCI (orcl1) 8> view params mgr

port 7500

dynamicportlist 7500-7505

autorestart extract *,waitminutes 2 ,retries 5

GGSCI (orcl1) 10> start mgr

GGSCI (orcl1) 9> info mgr
Manager is running (IP port orcl1.7500).

 3.2 配置SourceDB 的复制队列

edit params ext1

extract ext1

userid ggate,password ggate

rmthost 192.168.1.176, mgrport 7500

rmttrail /u01/ggate/dirdat/ht

ddl include mapped objname scott.*;

table scott.*;

增加抽取：

GGSCI (orcl1) 20>add extract ext1,tranlog, begin now
  GGSCI (orcl1) 20>add exttrail /u01/ggate/dirdat/lt, extract ext1

3.4  配置TargetDB 同步队列

  3.4.1 在Target 端添加checkpoint表：

GGSCI (orcl2) 20> edit params ./GLOBALS

CHECKPOINTTABLE ggate.checkpoint

GGSCI (orcl2) 12> dblogin userid ggate,password ggate

Successfully logged into database.

--说明，这个用户是在Source 库启用DDL 创建的，我在Target 库也创建了这个用户。

GGSCI (orcl2) 13> add checkpointtable ggate.checkpoint

Successfully created checkpoint tableGGATE.CHECKPOINT.

3.4.2 创建同步队列

GGSCI (orcl2) 41> view params rep1

replicat rep1
ASSUMETARGETDEFS
userid ggate,password ggate
discardfile /u01/ggate/dirdat/rep1_discard.txt,append, megabytes 10
DDL
map scott.*, target scott.*;

GGSCI（orcl2) 14> add replicat rep1,exttrail /u01/ggate/dirdat/lt, checkpointtable ggate.checkpoint

REPLICAT added.

3.4.3 开启服务

3.4.4 验证数据同步：

源库：

GGSCI (orcl1) 56> info ext1
EXTRACT    EXT1      Last Started 2014-10-22 13:04   Status RUNNING
Checkpoint Lag       00:00:00 (updated 00:20:46 ago)

           SCN 0.1074279 (1074279)

目标库：

GGSCI (orcl2) 47> info rep1
REPLICAT   REP1      Last Started 2014-10-22 10:53   Status RUNNING
Checkpoint Lag       00:00:00 (updated 00:00:05 ago)

         2014-10-22 13:04:59.361201  RBA 1072

DML测试

(源库）SQL> insert into t select * from emp;
14 rows created.
SQL> commit;
Commit complete.
SQL> select count(*) from t;

COUNT(*)
----------
14

（目标库）

SQL> select count(*) from t;

  COUNT(*)
----------
14==>>DML操作同步成功

DDL测试

SQL> drop table t;（源库）
Table dropped.

SQL> desc t;
ERROR:
ORA-04043: object t does not exist（目标库）==>>DDL操作同步成功

--THE END--
