目的：本博文给出11.2.0.4 oracle数据库ogg搭建过程中，备库的准备过程包括2种方式：第一种是主库rman全量备份后恢复，第二种是expdp从主库导出用户然后在备库导入。

对ogg数据同步进行测试，主要偏重类似Mysql的半同步数据，即备库从主库同步部分数据。

?
一、ogg相关服务器基本信息

二、主库调整
1、主库开启归档模式
select log_mode from v$database;
 oracle 11.2.0.4 ogg for centos6.8安装及数据半同步测试
如果主库没有开启归档模式则开启归档模式
2、打开数据库force-logging及补充日志
alter database force logging;
alter database add supplemental log data;
alter database add  supplemental log data (primary key) columns;

oracle 11.2.0.4 ogg for centos6.8安装及数据半同步测试
  
3、处理压缩表及分区压缩表，将其变为非压缩表
select 'alter table '||table_owner||'.'||table_name||' move partition '||partition_name||' nocompress update indexes;' from dba_tab_partitions where compression ='ENABLED' and table_owner='HR';
4、处理nologging的表，将其修改为logging的表
select 'alter table '||owner||'.'||table_name||' logging;' from dba_tables where owner in ('HR') and logging='NO';
5、处理nologging分区表为logging分区
select distinct 'alter table '||table_owner||'.'||table_name||' logging;' from dba_tab_partitions where table_owner in('HR') and logging='NO';


6、主库创建OGG专用用户
create tablespace goldengate datafile '$ORACLE_BASE/oradata/$ORACLE_SID/goldengate.dbf' size 100M autoextend on;


CREATE USER GOLDENGATE IDENTIFIED BY GOLDENGATE DEFAULT TABLESPACE GOLDENGATE TEMPORARY TABLESPACE TEMP; 
GRANT CONNECT TO GOLDENGATE;                                 
GRANT ALTER ANY TABLE TO GOLDENGATE; 
GRANT ALTER SESSION TO GOLDENGATE;                        
GRANT CREATE SESSION TO GOLDENGATE;                       
GRANT FLASHBACK ANY TABLE TO GOLDENGATE;                  
GRANT SELECT ANY DICTIONARY TO GOLDENGATE;                
GRANT SELECT ANY TABLE TO GOLDENGATE;                     
GRANT RESOURCE TO GOLDENGATE;    
GRANT SELECT ANY TRANSACTION TO GOLDENGATE;
四、主库源数据备份
1、rman全备份
backup database fORMat '/home/oracle/rman/full_%D_%d_%U.bak';


select current_scn from v$database;


alter system switch logfile;


backup arcHivelog all format '/home/oracle/rman/arch_%D_%d_%U.bak';


2、expdp按方案导出
2.1 测试数据来源
[oracle@ogg1 ~]$ sqlplus / as sysdba

2.2 expdp备份
[oracle@ogg1 ~]$ cat param

[oracle@ogg1 ~]$
五、备库目标数据恢复
恢复前准备
如源库开启闪回，需创建同等闪回目录即$ORACLE_BASE/ fast_recovery_area，否则报错：
 oracle 11.2.0.4 ogg for centos6.8安装及数据半同步测试
需要建立与主库同等的审计目录，否则报错：
mkdir -p /u01/oracle/app/oracle/admin/orcl/adump
 oracle 11.2.0.4 ogg for centos6.8安装及数据半同步测试
备库创建数据目录：
mkdir –p /u01/oracle/app/oracle/oradata/orcl/
1、rman全恢复
rman target /
RMAN> startup nomount;


RMAN> restore spfile from '/home/oracle/rman/full_25_ORCL_02sfc009_1_1.bak';


RMAN> shutdown immediate;


RMAN> startup nomount;


RMAN> restore controlfile from '/home/oracle/rman/full_25_ORCL_02sfc009_1_1.bak';


RMAN> alter database mount;


RMAN> restore database;


RMAN>  catalog start with '/home/oracle/rman';


RMAN> run{
 set until scn 996247;
 recover database;
 }
--这里的SCN号是主库源数据备份时查出来的SCN号，就是第四部里边的执行绿色sql命令时查出来的，注意一定要有。
2、备库expdp备份导入
2.1 创建directory
create directory zhul as ‘/home/oracle’;
2.2 创建Ogg专用用户
CREATE USER GOLDENGATE IDENTIFIED BY GOLDENGATE DEFAULT TABLESPACE GOLDENGATE TEMPORARY TABLESPACE TEMP; 
GRANT CONNECT TO GOLDENGATE;                                 
GRANT ALTER ANY TABLE TO GOLDENGATE; 
GRANT ALTER SESSION TO GOLDENGATE;                        
GRANT CREATE SESSION TO GOLDENGATE;                       
GRANT FLASHBACK ANY TABLE TO GOLDENGATE;                  
GRANT SELECT ANY DICTIONARY TO GOLDENGATE;                
GRANT SELECT ANY TABLE TO GOLDENGATE;                     
GRANT RESOURCE TO GOLDENGATE;    
GRANT SELECT ANY TRANSACTION TO GOLDENGATE;

2.3 数据导入

[oracle@ogg2 ~]$
六、主库安装OGG
1、创建安装目录
mkdir –p $ORACLE_BASE\ogg

2、上传并解压OGG软件


3、编辑OGG静默安装脚本

--结论：从源端控制目标端数据同步策略可以控制源端部分数据同步到目标端
?
6、expdp方式源端与目标端有差量数据DML
测试目的：在源端ogg安装完毕，extract进程配置恰当并处于启动状态，而目标端正在处理数据导入过程时，源端被同步的数据发生DML，在目标端的OGG安装完毕，目标端的replicat进程配置恰当并启动后，复制进程replicat可以应用目标端落后于源端的差量数据
6.1 删除目标端rep_zhul进程
