主库：
1.检查是否开启归档
select log_mode from gv$database;
archive log list;    ----注意归档路径需要是共享路径

2.检查是否开启force logging及补充日志
select force_logging,supplemental_log_data_min,supplemental_log_data_all,flashback_on from v$database;
开启：
alter database force logging;
alter database add supplemental log data;
alter system archive log current;

3.对主库检查，ogg不允许：唯一索引的索引列的列定义允许为null的
select dic.table_owner,dic.table_name,dic.index_name,di.uniqueness,dic.column_name
  from dba_ind_columns dic,dba_indexes di,dba_tab_columns dtc
 where dic.table_owner = '自行添加用户' -----修改用户名
   and dtc.OWNER = '自行添加用户' -----修改用户名
   AND dic.table_owner = di.table_owner
   and dic.TABLE_NAME = di.table_name
   and dic.index_name = di.index_name
   and di.uniqueness = 'UNIQUE'
   and dtc.owner = di.table_owner
   and dtc.TABLE_NAME = di.table_name
   and dic.column_name = dtc.COLUMN_NAME
   and dtc.nullable = ' Y '
   and dic.TABLE_NAME = dtc.TABLE_NAME;
不应该返回行，如果返回了，修改：要么变为非唯一索引，要么在保留唯一索引的情况下，将列的定义置为 not null。

4.创建ogg用户，并授权
create user goldengate identified by goldengate default tablespace users;
grant dba to goldengate;
ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION = TRUE SCOPE=BOTH;

5.设置环境变量（oracle用户）
PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin:/ggs
export LD_LIBRARY_PATH=/ggs:$ORACLE_HOME/lib

6.检查是否有nologing方式的表（ogg不支持nologing方式创建的表）
select owner,table_name,logging from dba_tables where logging='NO' AND owner='用户名';
修改为logging的表的语法：alter table 表名 logging;
注意：在ext进程的参数文件里添加 dboptions allownologging可以让ext进程继续运行，但是会导致数据丢失。

7.两个节点上传ogg介质并解压，授权/ggs目录给oracle
chown oracle:dba /ggs -R
su - oracle
cd /ggs
unzip p22575475_1121032_Linux-x86-64.zip
tar xvf fbo_ggs_Linux_x64_ora11g_64bit.tar

8.源端数据库添加表的补充日志
进入ogg安装路径：
cd /ggs
ggsci
dblogin userid goldengate password goldengate
create subdirs
add trandata lm.testogg

9.配置DDL复制
使用goldengate作为存储DDL objects的用户
给goldengate授权：
GRANT EXECUTE ON UTL_FILE TO goldengate;

10.配置GLOBALS文件
ggsci
edit param ./GLOBALS中加入：
GGSCHEMA goldengate

11.如果是10g需要停用 recyclebin，11g就不需要了

12.数据库执行：
退出所有的oracle连接后执行：
cd /ggs
sqlplus / as sysdba
@marker_setup.sql
@ddl_setup.sql
Please move GOLDENGATE to its own tablespace
 @role_setup.sql
grant ggs_ggsuser_role to goldengate;
 @ddl_enable.sql

13.如果是有灾备演练的需求，需要配置sequence同步
cd /ggs   --ogg安装目录
sqlplus / as sysdba
@sequence.sql
GRANT EXECUTE on goldengate.updateSequence TO goldengate;

14.源端配置参数文件
su - grid
vi $ORACLE_HOME/network/admin/listener.ora
SID_LIST_LISTENER =
(SID_LIST =
 (SID_DESC =
  (GLOBAL_DBNAME = +ASM)
  (ORACLE_HOME=/u01/app/11.2.0/grid)
  (SID_NAME = +ASM1)
 )
)


su - oracle
cd $ORACLE_HOME/network/admin
vi tnsnames.ora
ASM =
 (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 186.168.100.3)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = +ASM)
      (SID_NAME = +ASM1)
    )
  )

===============================================

15.添加trial文件，每个50M
add exttrail  /ggs/dirdat/sd,extract extfull,MEGABYTES 50

16.添加传输进程
add extract dpfull exttrailsource /ggs/dirdat/sd

17.创建远程队列文件并将其指定给传输进程
add rmttrail /ggs/dirdat/td,extract dpfull,MEGABYTES 50

18.配置传输进程参数
edit param dpfull
==================================
extract dpfull

19.从源端去一次scn号   
select current_scn from v$database;       --

20.按照上面查询出的scn导出数据
expdp  sys/****** directory=  dumpfile=%U.dmp logfile=.log schemas=  parallel= flashback_scn=scn

21.启动mgr及抓取传输进程


备库：
1.创建ogg用户并授权
create user goldengatet identified by goldengatet default tablespace tbs_ogg;
grant dba to goldengatet;
exec dbms_streams_auth.grant_admin_privilege(grantee => 'GOLDENGATET',grant_privileges => true);
ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION = TRUE SCOPE=BOTH;

2.配置环境变量（oracle用户下）
export LD_LIBRARY_PATH=/ggs:$ORACLE_HOME/lib
export PATH=$HVR_HOME/bin:$PATH:$ORACLE_HOME/bin:$PATH:$HOME/bin:/ggs

3.两个节点上传ogg介质并解压，授权/ggs目录给oracle
chown oracle:dba /ggs -R
su - oracle
cd /ggs
unzip p22575475_1121032_Linux-x86-64.zip
tar xvf fbo_ggs_Linux_x64_ora11g_64bit.tar

4.创建ogg相关路径
进入ogg安装路径：
cd /ggs
ggsci
dblogin userid goldengatet password goldengatet
create subdirs

5.如果配置sequence，需要
cd /ggs   --ogg安装目录
sqlplus / as sysdba
@sequence.sql
GRANT EXECUTE on goldengatet.replicateSequence TO goldengatet;

6.配置参数文件
MGR：
edit param mgr
======================================
port 7809
autostart replicat *
autorestart replicat *,RESETMINUTES 60
PURGEOLDEXTRACTS /ggs/dirdat/td*,MINKEEPHOURS 2
======================================

7.添加checkpoint表
dblogin userid goldengate,password goldengate
ADD CHECKPOINTTABLE goldengate.ckptfull

8.添加目标端应用进程
add replicat repfull,exttrail /ggs/dirdat/td,CHECKPOINTTABLE goldengate.ckptfull
 
9.修改目标端应用进程参数
 edit params repfull
====================================================
replicat repfull
setenv ( NLS_LANG =  "AMERICAN_AMERICA.ZHS16GBK" )

assuMetargetdefs

userid goldengate,password goldengate

DBOPTIONS DEFERREFCONST,SUPPRESSTRIGGERS

--REPERROR 1403,DISCARD

map lm.testogg,target lm.testogg;
========================================
启动目标端应用进程前需要确认的事情：
第一，    在rep参数文件中有参数DEFERREFCONST禁用级联删除
第二，    在rep参数文件中有参数SUPPRESSTRIGGERS 在rep进程运行时抑制目的端数据库的触发器生效。
注意：SUPPRESSTRIGGERS此参数仅仅对10.2.0.5 及以后，11.2.0.2及以后的oracle 数据库版本才有效，所以，若是目的端数据库是10.2.0.4，还需要在目的端数据库中手工禁用触发器（用plsql dev就可以禁用）
第三，    Impdp已经导入完成

11.导入数据
impdp sys/aaa directory=dumpfile=.dmp tables=    exclude=statistics

12.收集统计信息
exec dbms_stats.gather_table_stats(OWNNAME => ‘LM’,TABNAME => ‘TESTOGG’,CASCADE => TRUE);

11.启动应用进程
start mgr
start repfull,aftercsn scn               ---源端取到的scn
