查看是否开启
GGSCI (cndba) 11>  info trandata test.test
GGSCI (cndba) 11>  add trandata test.*
Logging of supplemental redo data enabled for table TEST.TEST.
注意：为了方便这里直接添加整个用户下表级transdata，如果只是同步部分表的，请批量
执行add trandata test.tablename

4.1.3.配置extract抽取进程

oracle   14187 14185  0 15:44 pts/0    00:00:00 grep mgr

5.初始化数据-RMAN

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.

GGSCI (cndba) 1> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING                                           
EXTRACT     STOPPED     EXT1        00:00:00      00:40:35    
EXTRACT     STOPPED     PUMP1       00:00:00      00:26:42
--目标端
[oracle@host1 ~]$ cd /u01/app/oracle/ogg
[oracle@host1 ogg]$ ./ggsci

GGSCI (host1) 1> start mgr
Manager started.

GGSCI (cndba) 14> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING

5.2.启动源端的EXTRACT进程

GGSCI (cndba) 2> start ext1

Sending START request to MANAGER ...
EXTRACT EXT1 starting

GGSCI (cndba) 4> start pump1

Sending START request to MANAGER ...
EXTRACT PUMP1 starting


GGSCI (cndba) 5> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

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$transaction 视图来查看数据库中的交易：
select min(start_time) from  v$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 {
allocate channel ch00 type disk maxpiecesize 10g;
allocate channel ch01 type disk maxpiecesize 10g;
sql 'alter system switch logfile';
sql 'alter system switch logfile';
sql 'alter system switch logfile';
sql 'alter system switch logfile';
crosscheck backupset;
delete noprompt expired backupset;
backup database format '/u01/backup/bk_%s_%p_%t';
sql 'alter system archive log current';
BACKUP ARCHIVELOG ALL FORMAT '/u01/backup/ARCH_%U';
BACKUP CURRENT CONTROLFILE FORMAT '/u01/backup/bk_controlfile';
release channel ch00;
release channel ch01;
}
--将备份文件拷贝到目标主机上。
cd /u01/backup/
[root@www.cndba.cn backup]# scp * 192.168.1.86:/u01/backup/
--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
5.5.1.讲数据库启动到nomount
SQL> startup nomount
ORACLE instance started.

Total System Global Area 1060585472 bytes
Fixed Size   2260000 bytes
Variable Size 905970656 bytes
Database Buffers 146800640 bytes
Redo Buffers   5554176 bytes

5.5.2.恢复控制文件

RMAN> restore controlfile from '/u01/backup/bk_controlfile';

Starting restore at 07-JUN-18
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=18 device type=DISK

output file name=/u01/app/oracle/oradata/cndba/control02.ctl
Finished restore at 07-JUN-18

5.5.3.将数据库启动到mount

SQL> alter database mount;

Database altered.

5.5.4.注册备份集

RMAN> catalog start with '/u01/backup/';

using target database control file instead of recovery catalog
searching for all files that match the pattern /u01/backup/

List of Files Unknown to the Database

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
checkpointtable ogg.checkpoint

GGSCI (cndba) 9> dblogin userid ogg,password ogg
Successfully logged into database.

GGSCI (cndba) 10> add checkpointtable ogg.checkpoint   

Successfully created checkpoint table ogg.checkpoint.

5.5.8.配置replicat复制进程

GGSCI (cndba) 11> add replicat rep1, exttrail ./dirdat/et, checkpointtable ogg.checkpoint
REPLICAT added.

GGSCI (cndba) 12> edit params rep1
GGSCI (cndba) 13> view params rep1

REPLICAT rep1
setenv (ORACLE_SID=cndba)
SETENV (ORACLE_HOME = "/u01/app/oracle/product/11.2.0/db_1")
USERID ogg,PASSWORD ogg
ASSUMETARGETDEFS
HANDLECOLLISIONS
REPERROR (DEFAULT, DISCARD)
DDLERROR DEFAULT DISCARD
DDLOPTIONS REPORT
DISCARDFILE ./dirrpt/repr1.dsc,append,megabytes 100
MAP test.*, TARGET test.*;

5.5.9.用SCN 启动Replicat

[oracle@www.cndba.cn ogg]$ cd $OGG_HOME
[oracle@www.cndba.cn ogg]$ ./ggsci

GGSCI (cndba) 15> start rep1, aftercsn 1066024

Sending START request to MANAGER ...
REPLICAT REP1 starting

GGSCI (cndba) 33> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING                                           
REPLICAT    RUNNING     REP1        00:00:00      00:00:07

6.检查同步是否正常

6.1.DML测试

--检查目标端数据是否正常
GGSCI (cndba) 4> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING                                           
REPLICAT    RUNNING     REP1        00:00:00      00:00:06
SQL> select * from test;

ID NAME
---------- --------
1 zhangsan
2 lisi
--源端表中添加数据
SQL> insert into test values(3,'wanger');

1 row created.

SQL> commit;

Commit complete.

SQL> select * from test;

ID NAME
---------- --------
1 zhangsan
2 lisi
3 wanger
--目标端查看
SQL> select * from test;
ID NAME
---------- --------
1 zhangsan
2 lisi
3 wanger
可以看到可以同步过来的。

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
grant GGS_GGSUSER_ROLE to ogg;
@ddl_enable.sql
@ddl_pin ogg
@marker_status

7.3.源端extract 配置

GGSCI (cndba) 12> edit params ext1
GGSCI (cndba) 16> view params ext1

EXTRACT ext1
SETENV (NLS_LANG="AMERICAN_AMERICA.ZHS16GBK") --此处数据库字符集设为一致
--SETENV (ORACLE_SID = "cndba")
SETENV (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
USERID ogg, PASSWORD ogg
THREADOPTIONS MAXCOMMITPROPAGATIONDELAY 20000
EXTTRAIL ./dirdat/et
DYNAMICRESOLUTION
DDL INCLUDE ALL
TABLE test.*;
重启extract进程
GGSCI (cndba) 13> stop ext1 

Sending STOP request to EXTRACT EXT1 ...
Request processed.

GGSCI (cndba) 14> start ext1

Sending START request to MANAGER ...
EXTRACT EXT1 starting

7.4.目标端replicat 配置

GGSCI (cndba) 8> edit params rep1
GGSCI (cndba) 9> view params rep1

REPLICAT rep1
setenv (ORACLE_SID=cndba)
SETENV (ORACLE_HOME = "/u01/app/oracle/product/11.2.0/db_1")
USERID ogg,PASSWORD ogg
ASSUMETARGETDEFS
HANDLECOLLISIONS
REPERROR (DEFAULT, DISCARD)
DDLERROR DEFAULT DISCARD
DDLOPTIONS REPORT
DISCARDFILE ./dirrpt/repr1.dsc,append,megabytes 100
MAP test.*, TARGET test.*;
ddl include all 
ddlerror default ignore retryop maxretries 3 retrydelay 5
重启replicat进程
GGSCI (cndba) 10> stop rep1

Sending STOP request to REPLICAT REP1 ...
Request processed.


GGSCI (cndba) 11> start rep1

Sending START request to MANAGER ...
REPLICAT REP1 starting

7.5.DDL测试

--源端：
SQL> create table test1 (id number(10) primary key ,name varchar(8));

Table created.

SQL> insert into test1 values(1,'zhangsan');

1 row created.

SQL> commit;

Commit complete.
--目标端：
SQL> desc test1
 Name  Null?    Type
 ----------------------------------------- -------- ----------------------------
 ID  NOT NULL NUMBER(10)
 NAME   VARCHAR2(8)
