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

[root@www.cndba.cn ogg]# chown -R oracle:oinstall /u01/app/oracle/ogg
注意：/u01/app/oracle/ogg 是 $OGG_HOME

3.1.4. 运行 ogg 并创建目录

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]$ ./ggsci

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.

5.5.2. 恢复控制文件

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

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

Do you really want to catalog the above files (enter YES or NO)? yes

5.5.5. 恢复数据库

RMAN> RESTORE 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 ...
R
SQL> insert into test1 values(1,'zhangsan');

1 row created.

SQL> commit;

EPLICAT REP1 starting

7.5.DDL 测试

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

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

SQL> select * from test1;

ID NAME
---------- --------
1 zhangsan
