GGSCI (dev160) 2> exit
2、创建管理用户及赋权：
create user GGUSER
IDENTIFIED by GGUSER
default tablespace USERS
temporary tablespace TEMP
profile DEFAULT
quota unlimited on USERS;
-- Grant/Revoke role privileges
grant connect to GGUSER;
grant resource to GGUSER;
-- Grant/Revoke system privileges
grant unlimited tablespace to GGUSER;
3、由于GG需要关闭10G的回收站机制，因此进行如下操作:
SQL> alter system set recyclebin=off;
System altered.
4、由于GG需要开启数据库的归档，因此需要进行如下操作：
SQL> archive log list
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 40
Current log sequence 42
SQL> alter database close
2 ;

5、安装同步DLL语句要用到的GoldenGate脚本
1）执行marker_setup脚本，该脚本用以建立一个DDL标记表
SQL> @/ora10/gg10/marker_setup（此处文件位置以具体各主机地址为准）
[ora10@dic5f88 gg10]$ sqlplus / as sysdba
SQL*Plus: Release 10.2.0.4.0 - Production on Mon Mar 7 08:35:10 2011
Copyright (c) 1982, 2007, Oracle. All Rights Reserved.
Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> @/ora10/gg10/marker_setup
Marker setup script
You will be prompted for the name of a schema for the GoldenGate database objects.
NOTE: The schema must be created prior to running this script.
NOTE: Stop all DDL replication before starting this installation.

Script. complete.
注：由于在一台机器上进行，因此在完成一个实例的某一步聚的安装后，需要退出sqlplus，以防sqlplus将访问过的文件锁住。
2）以INITIALSETUP选项运行ddl_setup.sql 将在数据库中创建捕获DDL语句的Trigger等必要组件
SQL> @/u01/ora10g/gg10/ddl_setup;
GoldenGate DDL Replication setup script
Verifying that current user has privileges to install DDL Replication...
Checking user sessions...
Check complete.
You will be prompted for the name of a schema for the GoldenGate database objects.
NOTE: For an Oracle 10g source, the system recycle bin must be disabled. For Oracle 11g and later, it can be enabled.
NOTE: The schema must be created prior to running this script.
NOTE: Stop all DDL replication before starting this installation.
Enter GoldenGate schema name:gguser
You will be prompted for the mode of installation.
To install or reinstall DDL replication, enter INITIALSETUP
To upgrade DDL replication, enter NORMAL

3）role_setup脚本用以建立GGS_GGSUSER_ROLE角色
SQL> @/u01/ora10g/gg10/role_setup
GGS Role setup script
This script. will drop and recreate the role GGS_GGSUSER_ROLE
To use a different role name, quit this script. and then edit the params.sql script. to change the gg_role parameter to the preferred name. (Do not run the script.)
You will be prompted for the name of a schema for the GoldenGate database objects.
NOTE: The schema must be created prior to running this script.
NOTE: Stop all DDL replication before starting this installation.
Enter GoldenGate schema name:gguser
Wrote file role_setup_set.txt
PL/SQL procedure successfully completed.
Role setup script. complete
Grant this role to each user assigned to the Extract, GGSCI, and Manager processes, by using the following SQL command:
GRANT GGS_GGSUSER_ROLE TO
where is the user assigned to the GoldenGate processes.
4）按上一步的提示，将权限赋给在 Extract, GGSCI, and Manager processes中指定的用户gguser
SQL> grant GGS_GGSUSER_ROLE gguser;
grant GGS_GGSUSER_ROLE gguser
*
ERROR at line 1:
ORA-00990: missing or invalid privilege
SQL> grant GGS_GGSUSER_ROLE to gguser;
Grant succeeded.
5)ddl_enable.sql将正式enable ddl捕获触发器，即:ALTER TRIGGER sys .&ddl_trigger_name ENABLE
SQL> @/u01/ora10g/gg10/ddl_enable;
Trigger altered.
6)执行dbmspool包将在数据库中创建DBMS_SHARED_POOL包，之后需要用到
SQL> @?/rdbms/admin/dbmspool
Package created.
Grant succeeded.
View created.
Package body created.
7)ddl_pin.sql通过dbms_shared_pool.keep存储过程将DDLReplication相关的对象keep在共享池中，以保证这些对象不要reload，提升性能
SQL> @/u01/ora10g/gg10/ddl_pin
Enter value for 1: gguser
PL/SQL procedure successfully completed.
Enter value for 1: gguser
PL/SQL procedure successfully completed.
PL/SQL procedure successfully completed.
以上DDL支持包对象都已经安装好，接下来就是配置manager,replicat和extract
6、manager的配置
GGSCI (dic5f88) 6> view param mgr
port 7908
AUTOSTART ER *
AUTORESTART EXTRACT *,RETRIES 3,WAITMINUTES 5,RESETMINUTES 60
DYNAMICPORTLIST 7940-8100,7930
SOURCEDB gzcrm20,USERID gguser,PASSWD gguser(这一行参数有问题，其它没问题)
PURGEOLDEXTRACTS /ora10/ggtrails/local/*,USECHECKPOINTS,MINKEEPDAYS 2
此处sourcedb只有在异构数据库的情况下才能使用，对于同构ORACLE数据库，不需要使用
GGSCI (ora10g) 4> view params mgr
port 7908
AUTOSTART ER *
AUTORESTART EXTRACT *,RETRIES 3,WAITMINUTES 5,RESETMINUTES 60
DYNAMICPORTLIST 7940-8100,7930
USERID system@localhost:1521/ggtarge PASSWORD oracle
PURGEOLDEXTRACTS /u01/ora10g/ggtrail/local/*,USECHECKPOINTS,MINKEEPDAYS 2
PURGEOLDEXTRACTS /u01/ora10g/ggtrail/remote/*,USECHECKPOINTS,MINKEEPDAYS 2
GGSCI (ora10g) 2> start manager
Manager started.
GGSCI (ora10g) 3> status manager
Manager is running (IP port ora10g.7908).
以下配置，是针对source数据库的
7、配置extract
1)在数据库级打开 追加日志 功能
SQL> alter database add supplemental log data;
Database altered.
SQL> alter system switch log;
alter system switch log
*
ERROR at line 1:
ORA-01900: LOGFILE keyword expected
SQL> alter system switch logfile;
System altered.
2)增加extract组
GGSCI (ora10g) 5> ADD EXTRACT emp_ext1, TRANLOG, BEGIN NOW
EXTRACT added.
GGSCI (ora10g) 6> status extract;
ERROR: Invalid command.
GGSCI (ora10g) 7> status extract
ERROR: You must specify a group name.
GGSCI (ora10g) 8> status extract emp_ext1
EXTRACT EMP_EXT1: STOPPED
3)接下来，我们要添加一个 RMTTRAIL 或 EXTTRAIL。前者用于远程计算机，如果您在同一台本地计算机上建立复制，则建议使用后者。我们将使用 EXTTRAIL，通过以下命令来创建它
GGSCI (ora10g) 9> add exttrail /u01/ora10g/ggtrail/local/ex,megabytes 10,extract emp_ext1
EXTTRAIL added.
4)为 Extract 组 emp_ext1创建参数文件
extract emp_ext1
USERID [email protected]:1521/orcl, PASSWORD tqtwfgwg
EXTTRAIL /u01/ora10g/ggtrail/local/ex
DDL INCLUDE MAPPED
Table test.*;
5)启动extract
GGSCI (ora10g) 35> start extract emp_ext1
Sending START request to MANAGER ...
EXTRACT EMP_EXT1 starting
GGSCI (ora10g) 36> info extract emp_ext1 detail

从结果来看，是这几个对象不存在所到，是不是真不存在呢？我们到dba_objects里去查看一下：
-bash-3.2$ echo $ORACLE_SID
orcl
-bash-3.2$ sqlplus / as sysdba

OWNER OBJECT_NAME

GGUSER GGS_MARKER

GGUSER GGS_DDL_HIST

结果已经很明确显示，对象是存在的，只是用户不是system下，所以，刚刚在文件中配置的userid是有问题的。
另外，它诊断数据库的归档目录没有指定，这个最好还是指定一下
因此，可做如下处理：
A、指定归档目录:

GGSCI (ora10g) 43> status extract emp_ext1
EXTRACT EMP_EXT1: RUNNING
OK，总算把extract进程搞定
以下配置，是针对target数据库的
8、配置replicat组的参数信息
1)在目标库上创建checkpointtable
知识补充：此表中保存的检查点指示 Replicat 进程的当前读写位置。这用于在进程需要重启时或者在服务器出现任何故障或网络停顿时防止数据丢失。如果没有这一机制，将导致数据丢失。另一个好处是，通过使用检查点，多个 Extract 或 Replicat 进程可通过相同的一组线索进行读取。
对于以批处理模式运行的 Extract 和 Replicat 进程，检查点不是必需的，因为这样的进程总是可以重启。然而，在 Extract 和 Replicat 进程连续工作的情况下，检查点是必需的。检查点通常保存在 dirchk 子目录的文件中，但是对于 Replicat，可以选择在数据库的检查点表中保存检查点。

ERROR: Invalid command.
GGSCI (ora10g) 29> add checkpointtable gguser.rep_checkpoint
Successfully created checkpoint table GGUSER.REP_CHECKPOINT.
2)添加 Replicat 组
GGSCI (ora10g) 44> ADD REPLICAT emp_rep1, EXTTRAIL /u01/ora10g/ggtrail/local/ex, CHECKPOINTTABLE gguser.rep_checkpoint,begin now
REPLICAT added.
3)配置Replicat 组的参数文件
GGSCI (ora10g) 45> edit params emp_rep1
REPLICAT emp_rep
USERID [email protected]:1521/ggtarge, PASSWORD gguser
REPERROR 1756,DISCARD
REPERROR DEFAULT,DISCARD
discardfile /u01/ora10g/discard/rep1.log,append,megabytes 10
ASSUMETARGETDEFS
HANDLECOLLISIONS
MAP test.*, TARGET test.*;
4)启动Replicat 组
GGSCI (ora10g) 47> start replicat emp_rep1

REPLICAT EMP_REP1 starting
GGSCI (ora10g) 48> status emp_rep1

再次经历失败，悲剧
5）查看日志，定位问题
-bash-3.2$ tail -100f /u01/ora10g/gg10/dirrpt/EMP_REP1.rpt
...
2010-12-07 20:02:58 ERROR OGG-00446 Could not open checkpoint file /u01/ora10g/gg10/dirchk/EMP_REP.cpr, mode 1 (error 2, No such file or directory).
2010-12-07 20:02:58 ERROR OGG-01668 PROCESS ABENDING.
错误报得很奇怪，说是一个checkpoint file找不到，我不是建的表吗？怎么成了文件了。
最关键的是，我的进程不是emp_rep1吗，怎么是emp_rep.cpr了
进目录查看:
-bash-3.2$ cd /u01/ora10g/gg10/dirchk/
-bash-3.2$ ls -l
total 8
-rw-rw-r-- 1 oracle oinstall 4096 Dec 7 20:08 EMP_EXT1.cpe
-rw-rw-r-- 1 oracle oinstall 2048 Dec 7 19:56 EMP_REP1.cpr
果然发现不存在EMP_REP.cpr文件，但存在EMP_REP1.cpr文件
查看之前的配置文件，果然发现第一行有问题:
REPLICAT emp_rep
USERID [email protected]:1521/ggtarge, PASSWORD gguser
REPERROR 1756,DISCARD
REPERROR DEFAULT,DISCARD
discardfile /u01/ora10g/discard/rep1.log,append,megabytes 10
ASSUMETARGETDEFS
HANDLECOLLISIONS
MAP test.*, TARGET test.*;
该死的粗心
修改如下：
REPLICAT emp_rep1
USERID [email protected]:1521/ggtarge, PASSWORD gguser
REPERROR 1756,DISCARD ---reperror错误，指定在出现该错误时，复制进行的处理方式（默认为abended，可有ignore,exception,discard等其它操作)
REPERROR DEFAULT,DISCARD
discardfile /u01/ora10g/discard/rep1.log,append,megabytes 10
ASSUMETARGETDEFS ----这个参数指定在进行DML操作时，两边的对象结果是完全一致的，一般在DML操作中省略两边表结果的检查
HANDLECOLLISIONS
MAP test.*, TARGET test.*;
