环境

oracle12c 12.1.0.2.0
ogg 19.1
linux Ubuntu 14.04.3 LTS
172.18.0.2 源数据库地址
172.18.0.3 目标数据库地址html

ogg根据scn同步数据，源库零停机时间

以下是主要步骤：linux

配置好ogg源端的mgr、抓取和传送进程，并启动。
配置好ogg目标端的mgr、复制进程，仅启动mgr。
源端可自由进行交易，此时观察源与目标的trail文件是否都正常。
查询源端此时的scn，并按照参数flashbask_scn进行expdp。
目标端impdp导入。
目标端start replicat xxx,aftercsn xxxxx

配置和使用GoldenGate的步骤

1 在源端和目标端配置数据库支持GoldenGate 2 在源端和目标端建立和配置GoldenGate实例 3 在源端建立和配置主抽取进程(Primary Extract) 4 在源端建立和配置Data Pump进程(Secondly Extract) 5 在目标端建立和配置Replicat进程sql

安装步骤

源数据库配置步骤

开启归档，--如未开启，从新开启须要重启实例，在mount状态下数据库

Alter database archivelog;
修改oracle日志模式：
sqlplus /nolog
conn / as sysdba
1，关闭数据库：shutdown immediate;
2，启动数据库实例到mount状态：startup mount;
3，切换数据库日志模式：
      alter database archivelog;（设置数据库为归档日志模式）
      alter database noarchivelog;（设置数据库为非归档日志模式）
4，打开数据库：alter database open;
5，确认数据库处于归档模式：archive log list;

开启Force loggingvim

Alter database force logging;

开启supplemental loggingbash

Alter database add supplemental log data;
alter system switch logfile;
alter database force logging;

设置数据库GoldenGate参数网络

show parameter enable_goldengate_replication;
alter system set enable_goldengate_replication=true scope=both ; --RAC的全部实例也须要设置
alter system set enable_goldengate_replication=true scope=both sid='*';

建立OGG表空间oracle

create tablespace ogg_tbs datafile '/u01/app/oracle/oradata/xe/ogg_tbs.dbf' size 5G AUTOEXTEND on extent management local segment space management auto ;

--如要启用DDL功能，OGG用户须要独立的表空间。
建立OGG帐号app

create user ggadm identified by "oracle" default tablespace ogg_tbs;
ALTER USER   GGADM QUOTA UNLIMITED ON  OGG_TBS;

给OGG帐号赋权
--源端：无DDL，不使用DBA权限的状况： ---For 集成模式，db 12.0.1.0
--The following privileges apply to Oracle versions 11.2.0.4 or later.
--源端：Extract Classic Mode ：ide

grant connect, resource,CREATE SESSION to ggadm;
exec dbms_goldengate_auth.grant_admin_privilege('ggadm');
exec dbms_goldengate_auth.grant_admin_privilege(grantee=>'ggadm');
grant select any dictionary to ggadm;
commit;

配置tnsnames.ora

vi $ORACLE_HOME/network/admin/tnsnames.ora 
OGGSource =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.101)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = mydb)
)
)

检测tnsping 和相关网络是否联通

OGG上传目录：telnet 192.168.56.101 7809
tnsping oggsource
$ sqlplus ggadm/oracle@oggsource

目录端数据库配置

设置ogg参数

alter system set enable_goldengate_replication=true scope=both sid='*';
create tablespace ogg_tbs datafile '/u01/app/oracle/oradata/xe/ogg_tbs.dbf' size 5G AUTOEXTEND on extent management local segment space management auto ;
create user ggadm identified by "oracle" default tablespace ogg_tbs;
ALTER USER  ggadm QUOTA UNLIMITED ON ogg_tbs;
grant 
CREATE SESSION,
ALTER SESSION,
ALTER SYSTEM,
RESOURCE,
SELECT ANY DICTIONARY,
FLASHBACK ANY TABLE,
SELECT ANY TABLE,
SELECT ANY TRANSACTION,
insert any table,
update any table,
delete any table,
drop any table,
CREATE TABLE
to ggadm;
grant SELECT on dba_clusters to ggadm;
grant SELECT on V_$DATABASE to ggadm;
grant select on sys.logmnr_buildlog to ggadm;
grant EXECUTE on DBMS_FLASHBACK to ggadm;
grant execute on DBMS_CAPTURE_ADM to ggadm;
grant execute on DBMS_STREAMS to ggadm;  
grant EXECUTE_CATALOG_ROLE to ggadm;
grant connect, resource,CREATE SESSION to ggadm;
exec dbms_goldengate_auth.grant_admin_privilege('ggadm');
exec dbms_goldengate_auth.grant_admin_privilege(grantee=>'ggadm');
grant select any dictionary to ggadm;

配置tnsnames.ora

oggtarget =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = oracle12c-target)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = xe)
    )
  )

数据库附加日志

附加日志级别分为:

数据库级别的附加日志(必须附加日志)
用户级别的附加日志(当使用GoldenGate DDL抽取功能时要启用该级别)
表级别的附加日志(必须附加日志，除非你启用了用户级别的附加日志)

数据库级别的附加日志
由于GoldenGate须要抽取捕获变动数据信息和元数据信息，这些信息须要记录日志，而且由于日志老是持续增加的，这些日志增加的信息对于GoldenGate是必须记录的，因此必须在GoldenGate进程启动前开启数据库级别的附加日志；检查数据库是否开启附加日志:

SELECT supplemental_log_data_min, force_logging FROM v$database;
SUPPLEME FOR
-------- ---
NO       NO

开启数据库级别的附加日志:

SYS@sydb>alter database add supplemental log data;
SYS@sydb>ALTER DATABASE FORCE LOGGING;

SYS@sydb>SELECT supplemental_log_data_min, force_logging FROM v$database;

SUPPLEME FOR
-------- ---
YES      YES
Elapsed: 00:00:00.00
SYS@sydb>alter system switch logfile;

System altered.
Elapsed: 00:00:00.09

用户级别的附加日志

开启用户级别的附加日志的管理用户必须具备执行DBMS_CAPTURE_ADM包的权限；能够在GoldenGate GGSCI命令行下登陆到数据库管理用户为其它的用户开启附加日志；
在GGSCI命令行下使用DBLOGIN命令登陆到数据库管理用户

GGSCI (sywu) 1> dblogin userid ogg_owner,password ogg_owner
Successfully logged into database.

为用户启用附加日志

GGSCI (sywu as ogg_owner@sydb) 2> add schematrandata scott
2015-08-24 14:56:26  INFO    OGG-01788  SCHEMATRANDATA has been added on schema scott.
2015-08-24 14:56:27  INFO    OGG-01976  SCHEMATRANDATA for scheduling columns has been added on schema scott.

取消用户附加日志

GGSCI (sywu as ogg_owner@sydb) 6> delete schematrandata scott
2015-08-25 20:14:49  INFO    OGG-01792  SCHEMATRANDATA has been deleted on schema scott.
2015-08-25 20:14:49  INFO    OGG-01979  SCHEMATRANDATA for scheduling columns has been deleted on schema scott.

表级别的附加日志
在没有启用用户级别的附加日志的状况下表级别的主键或惟一索引附加日志对于GoldenGate是必须的；在某些状况下即便你启用了用户级别的附加日志，你也能够启用表级别的附加日志使主键附加日志替代每个在用户级别为GoldenGate指定的键；必须在表没有主键或惟一索引的状况下启用表级别的附加日志。
在GGSCI命令行下使用dblogin登陆到数据库管理用户

GGSCI (sywu) 1> dblogin userid ogg_owner,password ogg_owner
Successfully logged into database.

为表启用附加日志

GGSCI (sywu as ogg_owner@sydb) 3> add trandata ogg_owner.togg
Logging of supplemental redo data enabled for table OGG_OWNER.TOGG.
TRANDATA for scheduling columns has been added on table 'OGG_OWNER.TOGG'.

注意:仅当该表有主键或惟一索引时使用上面的命令启用表级别的附加日志，若是表中没有主键或惟一索引时则必须指定一个或多个或者所有列作为主键，在GoldenGate这些键的做用是过滤重复的数据。

SYS@sydb>create table ogg_owner.togg_nokey(id,name,type,CREATED,update_date) 
      as 
 select object_id,object_name,object_type,CREATED,sysdate from dba_objects  where rownum<1001
Table created.
Elapsed: 00:00:00.11

在没有主键而且没有指定主键时启用表级别附加日志，默认全部列作为主键:

GGSCI (sywu as ogg_owner@sydb) 4> add trandata ogg_owner.togg_nokey

2015-08-24 16:05:01  WARNING OGG-06439  No unique key is defined for table TOGG_NOKEY. All viable columns will be used to represent the key, but may not guarantee uniqueness. KEYCOLS may be used to define the key.

Logging of supplemental redo data enabled for table OGG_OWNER.TOGG_NOKEY.
TRANDATA for scheduling columns has been added on table 'OGG_OWNER.TOGG_NOKEY'.

在没有主键而且指定主键列的状况下启用表级别附加日志:

GGSCI (sywu as ogg_owner@sydb) 26>  add trandata ogg_owner.togg_nokey,cols (ID),nokey

2015-08-24 16:33:19  WARNING OGG-06439  No unique key is defined for table TOGG_NOKEY. All viable columns will be used to represent the key, but may not guarantee uniqueness. KEYCOLS may be used to define the key.

Logging of supplemental redo data enabled for table OGG_OWNER.TOGG_NOKEY.
TRANDATA for scheduling columns has been added on table 'OGG_OWNER.TOGG_NOKEY'.

安装ogg,源端与目录端安装方法相同

将ogg压缩文件放到源数据库与目录数据库的/ogg目录，这个目录根据实际状况设定

由于操做系统没有图形化，因此采用静默安装　　先复制一份配置文件

cd /ogg/fbo_ggs_Linux_x64_shiphome/Disk1/response/
cp oggcore.rsp oggcore-setup.rsp
vim oggcore-12c.rsp
修改这几项
INSTALL_OPTION=ORA12c
SOFTWARE_LOCATION=/u01/app/ogg
START_MANAGER=false

开始安装　 
mkdir /u01/app/ogg
chown -R oracle:dba /u01/app/ogg
chown -R oracle:dba /ogg
su - oracle
cd /ogg/fbo_ggs_Linux_x64_shiphome/Disk1
./runInstaller -silent -responseFile /ogg/fbo_ggs_Linux_x64_shiphome/Disk1/response/oggcore-12c.rsp

安装成功

配置.bash_profile

PATH=$PATH:$HOME/.local/bin:$HOME/bin
export PATH
export ORACLE_BASE=/data/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export ORACLE_SID=orcl

安装注意事项
安装过程当中注意如下几点：
1）安装过程当中若是可使用图形界面建议使用图形界面安装；
2）安装过程当中注意配置好环境变量，使用oracle用户安装；
3）若是用户没法提供oracle用户安装，建议安装用户必需要有oracle的全部组权限；
4）静默安装时注意仅须要编辑两个参数，MGR能够在安装完毕后配置，若是须要配置DATABASE_LOCATION，该参数应为$ORACLE_HOME；
5）建议安装过程当中若有报错须要及时处理，若是静默模式安装失败，建议彻底卸载或者更换安装目录。

OGG 配置过程(源端)
