3.GoldenGate安装
3.1.源端安装OGG
3.1.1.创建软件安装目录并赋权
[root@www.cndba.cn software]# mkdir -p /u01/app/oracle/ogg
[root@www.cndba.cn software]# chown -R oracle:oinstall /u01/app/oracle/ogg
3.1.2.配置oracle用户环境变量
[oracle@www.cndba.cn ~]$ vi .bash_profile
设置Library 路径
假设OGG的安装目录是/u01/app/oracle/ogg，那么在/home/oracle/.bash_profile文件里添加如下内容：
export OGG_HOME=$ORACLE_BASE/ogg
export PATH=$ORACLE_HOME/bin:$PATH:$OGG_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$OGG_HOME:/lib:/usr/lib
--source 使修改生效：
[oracle@www.cndba.cn ~]$ source .bash_profile
3.1.3.解压ogg文件
[root@www.cndba.cn software]# cd /software/
[root@www.cndba.cn software]# unzip ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip

5.初始化数据-EXPDP
5.1.启动生产端和容灾端的管理进程
--源端
[oracle@www.cndba.cn ogg]$ cd /u01/app/oracle/ogg
[oracle@www.cndba.cn ogg]$ ./ggsci
GGSCI (cndba) 1> start mgr
Manager started.

MANAGER RUNNING
EXTRACT RUNNING EXT1 00:00:00 00:00:03
EXTRACT RUNNING PUMP1 00:00:00 00:28:57
5.3.查看数据库中所有事务的开始时间
查看数据库中所有事务的开始时间，直到其大于抽取进程的启动时间再开始备份数
据库，因为GoldenGate 的只获取在Extract 启动以后的交易变化，在Extract 启动之
前开始而在Extract 启动以后才完成的交易GoldenGate 将会忽略这些交易，这些被忽
略的交易数据就会丢失。所以需要等数据库中所以的交易都在Extract 启动之后开始
的才能开始备份数据库。通过v$transaction 视图来查看数据库中的交易：
SQL> select * from v$transaction;
no rows selected
这里是测试环境没有事物，可以进行后面的备份了。
5.4.EXPDP 备份源端数据库
当所有在Extract 启动之前的开始的交易都完成后，我们就可以使用expdp 备份生产
端的数据库了。备份数据库的过程中一定要密切监控Extract 进程的状态，保证其一

5.4.1.源端查询当前数据库SCN
[root@www.cndba.cn ~]# mkdir /backup
[root@www.cndba.cn ~]# chown -R oracle:oinstall /backup
SQL> create or replace directory dump_dir as '/backup';
Directory created.

5.4.2.备份源端数据库
[oracle@www.cndba.cn ~]$ expdp system/oracle directory=dump_dir dumpfile=sender_%U.dmp logfile=user.log schemas=test parallel=2 flashback_scn= 1014991
…..
Dump file set for SYSTEM.SYS_EXPORT_SCHEMA_01 is:

Job "SYSTEM"."SYS_EXPORT_SCHEMA_01" successfully completed at Wed Jun 6 16:46:26 2018 elapsed 0 00:00:36
5.4.3.将备份文件传到目标端
目标端创建备份目录
[root@www.cndba.cn ~]# mkdir /backup
源端数据库传输到目标端
[oracle@www.cndba.cn backup]$ scp sender_0* 192.168.1.86:/backup/
在目标端给备份文件授权
[root@www.cndba.cn ~]# chown -R oracle:oinstall /backup/
5.5.IMPDP 初始化数据
5.5.1.Impdp 数据
SQL> create or replace directory dump_dir as '/backup';
Directory created.
[oracle@www.cndba.cn dirprm]$ impdp system/oracle directory=dump_dir dumpfile= sender_%U.dmp logfile=user.log parallel=2 table_exists_action=replace SCHEMAS=test

7.开启DDL
7.1.添加参数
GGSCI (cndba) 8> edit params ./GLOBALS
GGSCI (cndba) 9> view params ./GLOBALS
GGSCHEMA ogg
7.2.在源端执行与DDL同步相关的SQL脚本
切记@marker_setup.sql 一定要在cd $OGG_HOME目录下执行否则会卡主。执行脚本时要输入ogg管理用户，本实例是ogg。
cd /u01/app/oracle/ogg
sqlplus / as sysdba
grant execute on utl_file to ogg;
@marker_setup.sql
@ddl_setup.sql
@role_setup.sql
