3.GoldenGate 安装
3.1. 源端安装 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

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$transaction 视图来查看数据库中的交易：select min(start_time) from v$transaction;
这里是测试环境没有事物，可以进行后面的备份了。5.4.RMAN 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 RMAN 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
直正常运行：
5.4.1. 源端使用 RMAN 备份全库
注意：备份过程保证抽取进程状态一直正常。-- 备份归档和控制文件如果有三个日志文件组，可以按照以下方式进行切换，如果更多，则对应增加切换的次数即可）-- 备份数据库
run {

}

-- 在目标端给备份文件授权
[root@www.cndba.cn backup]# chown -R oracle:oinstall /u01/backup/
5.5. 恢复目标端数据库

5.5.3. 将数据库启动到 mount
SQL> alter database mount;

5.5.6. 使用以下 SQL 语句查找目标端数据库的 SCN 号：(得到该 SCN 号之后，启动复制进程时，使用该 SCN 号)
SQL> SELECT CHECKPOINT_CHANGE#,CHECKPOINT_TIME FROM V$DATAFILE_HEADER;
CHECKPOINT_CHANGE# CHECKPOINT_T
------------------ ------------
1066024 07-JUN-18
1066024 07-JUN-18
1066024 07-JUN-18
1066024 07-JUN-18
1066024 07-JUN-18
a) 如果目标端数据库在“5.4.1”操作之后，又额外追加了源数据库 rman 备份后的归档日志，导致目标端数据库的 SCN 号大于“5.4.1”中 SCN 号。所以必须以目标端数据库当前的 SCN 为主，从而避免数据重复。b) 如果目标端数据库在“5.4.1”操作之后，没有额外追加源数据库 rman 备份后的归档日志，则“5.5.6”中得到的 SCN 号应该与“5.4.1”中的 SCN 号相等；-- 以 resetlogs 方式打开数据库
SQL> alter database open resetlogs;
Database altered.
5.5.7. 添加 GLOBALS 参数文件，创新检查点表
GGSCI (cndba) 7> edit params ./GLOBALS
GGSCI (cndba) 8> view params ./GLOBALS
-- 添加以下内容：GGSCHEMA ogg

GGSCI (cndba) 9> dblogin userid ogg,password ogg

GGSCI (cndba) 10> add checkpointtable ogg.checkpoint

5.5.8. 配置 replicat 复制进程
