单机11g ogg 双向DML复制

环境说明： Linux为Linux 2.6.32-573.el6.x86_64 Oracle为 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production

ogg为 ogg112101_fbo_ggs_Linux_x64_ora11g_64bit
10.100.25.14 (原库ip) 10.100.25.16(目标库ip)

说明： goldengate为ogg管理用户 oggdemo为生产用户

源库、目标库都操作：

1. 上传ogg安装包与安装ogg软件。

[oracle@11g ~]$ mkdir ogg

[oracle@11g ~]$ cd ogg
[oracle@11g ogg]$ ls
ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip

[oracle@11g ogg]$ unzip ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip
Archive: ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip
inflating: fbo_ggs_Linux_x64_ora11g_64bit.tar
inflating: OGG_WinUnix_Rel_Notes_11.2.1.0.1.pdf
inflating: Oracle GoldenGate 11.2.1.0.1 README.txt

UserExitExamples/ExitDemo_more_recs/Makefile_more_recs.SOLARIS
。。。。省略大量输出。。。。。
ucharset.h
ulg.sql
usrdecs.h
zlib.txt

2. 数据库为ogg传递数据做环境调整。 （归档，数据库级最小附加日志）

[oracle@11g ogg]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Sun Nov 9 03:03:20 2014

SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 21
Next log sequence to archive 23
Current log sequence 23
SQL> alter database add supplemental log data;
Database altered.

SQL> ALTER SYSTEM ARCHIVE LOG CURRENT;
System altered.

3. 创建专用的ogg表空间与ogg用户，ogg用户授权 （以后卸载ogg直接删除表空间即可）

SQL> create tablespace goldgate datafile '/home/oracle/app/oradata/orcl/ogg01.dbf' size 2G AUTOEXTEND ON NEXT 5M MAXSIZE UNLIMITED LOGGING EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO ;
Tablespace created.

SQL> CREATE USER goldengate IDENTIFIED BY goldengate DEFAULT TABLESPACE goldgate;
User created.

SQL> GRANT CONNECT TO goldengate;
Grant succeeded.

SQL> GRANT CREATE SESSION TO goldengate;
Grant succeeded.

SQL> GRANT ALTER SESSION TO goldengate;
Grant succeeded.

SQL> GRANT RESOURCE TO goldengate;
Grant succeeded.

SQL> GRANT SELECT ANY DICTIONARY TO goldengate;
Grant succeeded.

SQL> GRANT SELECT ANY TABLE TO goldengate;
Grant succeeded.

SQL> GRANT FLASHBACK ANY TABLE TO goldengate;
Grant succeeded.

SQL> GRANT ALTER ANY TABLE TO goldengate;
Grant succeeded.

说明：
在goldengate目录下，执行 ./ggsci 进入命令行界面，左侧提示出现GGSCI (myhost) 1>，
表示进入成功
如果ggsci进入出错，设置一下环境变量：
export LD_LIBRARY_PATH=$ORACLE_HOME/lib

[oracle@11g ~]$ cd ogg --验证是否可以进入ggsci命令界面
[oracle@11g ogg]$ ./ggsci
Oracle GoldenGate Command Interpreter for Oracle

GGSCI (11g) 1> -- 成功进入界面

SQL> GRANT INSERT ANY TABLE TO goldengate;
Grant succeeded.

SQL> GRANT UPDATE ANY TABLE TO goldengate;
Grant succeeded.

SQL> GRANT DELETE ANY TABLE TO goldengate;
Grant succeeded.

4. 创建ogg子目录

源库与目标库都执行如下：

GGSCI (11g) 3> create subdirs
Creating subdirectories under current directory /home/oracle/ogg
Parameter files /home/oracle/ogg/dirprm: already exists
Report files /home/oracle/ogg/dirrpt: created
Checkpoint files /home/oracle/ogg/dirchk: created
Process status files /home/oracle/ogg/dirpcs: created
SQL script files /home/oracle/ogg/dirsql: created
Database definitions files /home/oracle/ogg/dirdef: created
Extract data files /home/oracle/ogg/dirdat: created
Temporary files /home/oracle/ogg/dirtmp: created
Stdout files /home/oracle/ogg/dirout: created

参数说明：

该命令会在OGG安装目录下建立若干子目录，其中几个主要目录如下所示：
dirchk：用于存放各个进程的检查点
dirdat：用于存放数据队列文件
dirprm：用于存放各进程参数文件
dirrpt：用于存放各进程报告
dirpcs：存放各个正在运行的进程信息

5. 创建mgr进程

GGSCI (11g) 4> edit param mgr （--在mgr文件中加入 port 7809）
GGSCI (11g) 8> view param mgr
port 7809

GGSCI (11g) 5> start mgr
Manager started.

GGSCI (11g) 6> info all

Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING

————————————————————————————————————————————————————

源库操作：

6. 创建oggdemo测试用户

SQL> create user oggdemo identified by oggdemo;
User created.

SQL> grant dba to oggdemo;
Grant succeeded.

SQL> conn oggdemo;
Enter password:
Connected.

SQL> create table oggdemo(id int);
Table created.

7. GGSCI命令行中登录数据库，为所有要复制的数据表添加trandata

GGSCI (11g) 9> dblogin userid oggdemo , password oggdemo
Successfully logged into database.

GGSCI (11g) 10> add trandata oggdemo.oggdemo
2014-11-09 04:12:37 WARNING OGG-00869 No unique key is defined for table 'OGGDEMO'. 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 OGGDEMO.OGGDEMO.

———————————————————————————————————————————————————————————————

目标端操作：

SQL> create user oggdemo identified by oggdemo;
User created.

SQL> grant dba to oggdemo;
Grant succeeded.

SQL> conn oggdemo;
Enter password:
Connected.

SQL> create table oggdemo(id int);
Table created.

————————————————————————————————————————————————————————

源库操作：

8. 创建ext进程，tail文件，data_pump进程

GGSCI (11g) 11> add ext exta, tranlog, begin now
EXTRACT added.

GGSCI (11g) 12> add exttrail /home/oracle/ogg/dirdat/la, ext exta, MEGABYTES 20 -- 创建源trail文件
EXTTRAIL added.

GGSCI (11g) 13> add extract dpea, EXTTRAILSOURCE /home/oracle/ogg/dirdat/la -- 创建data_pump进程
EXTRACT added.

GGSCI (11g) 14> add rmttrail /home/oracle/ogg/dirdat/ra, ext dpea, MEGABYTES 20 --创建目标端trail文件
RMTTRAIL added.

GGSCI (11g) 15> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
EXTRACT STOPPED DPEA 00:00:00 00:02:48
EXTRACT STOPPED EXTA 00:00:00 00:09:36

GGSCI (11g) 17> edit param exta --exta文件添加内容显示如下

GGSCI (11g) 35> view param exta

EXTRACT exta
setenv (NLS_LANG = AMERICAN_AMERICA.ZHS16GBK )
setenv (ORACLE_SID = orcl)
USERID goldengate, PASSWORD goldengate
EXTTRAIL /home/oracle/ogg/dirdat/la
dynamicresolution
table oggdemo.oggdemo;
TRANLOGOPTIONS EXCLUDEUSER goldengate

GGSCI (11g) 36> edit param dpea --dpea文件添加内容显示如下

GGSCI (11g) 39> view param dpea
extract dpea
setenv (NLS_LANG = AMERICAN_AMERICA.ZHS16GBK )
passthru
rmthost 10.100.25.16,mgrport 7809, compress
rmttrail /home/oracle/ogg/dirdat/ra
dynamicresolution
table oggdemo.oggdemo;

参数说明：

passthru表示本进程是一个传输进程data pump，无需跟数据库交互，只需要搬运数据即可；
因为data pump要传输数据到目标，所以需要配置rmthost和rmttrail指定目标主机和队列信息

———————————————————————————————————————————————————————————

目标数据库操作：

9. 创建目标数据库的replicate进程
GGSCI (11g) 6> add rep repa, exttrail /home/oracle/ogg/dirdat/ra, nodbcheckpoint
REPLICAT added.

参数说明：

repa为进程名，一般为rep开头表示是replicat进程，后面可以加1-2位字符标识，一般与ext进程对应；

exttrail表示要抽取的数据队列，注意是目标端的队列位置；

nodbcheckpoint表示不使用数据库检查点。

GGSCI (11g) 17> edit param repa -- repa文件添加内容显示如下

GGSCI (11g) 20> view param repa

replicat repa
setenv (NLS_LANG = AMERICAN_AMERICA.ZHS16GBK)
setenv (ORACLE_SID = orcl)
userid goldengate, password goldengate
reperror default,abend
discardfile /home/oracle/ogg/dirrpt/repa.dsc,append, megabytes 10
assumetargetdefs
dynamicresolution
map oggdemo.oggdemo, target oggdemo.oggdemo;

ok，至此单向复制已经配置完毕。

GGSCI (11g) 14> add rmttrail /home/oracle/ogg/dirdat/rb, ext dpeb, MEGABYTES 20 --创建目标端trail文件
RMTTRAIL added.

GGSCI (11g) 17> edit param extb --extb文件添加内容显示如下

GGSCI (11g) 35> view param extb

EXTRACT extb
setenv (NLS_LANG = AMERICAN_AMERICA.ZHS16GBK )
setenv (ORACLE_SID = orcl)
USERID goldengate, PASSWORD goldengate
EXTTRAIL /home/oracle/ogg/dirdat/lb
dynamicresolution
table oggdemo.oggdemo;
TRANLOGOPTIONS EXCLUDEUSER goldengate

GGSCI (11g) 39> view param dpeb
extract dpeb
setenv (NLS_LANG = AMERICAN_AMERICA.ZHS16GBK )
passthru
rmthost 10.100.25.14,mgrport 7809, compress
rmttrail /home/oracle/ogg/dirdat/rb
dynamicresolution
table oggdemo.oggdemo;

参数说明：

passthru表示本进程是一个传输进程data pump，无需跟数据库交互，只需要搬运数据即可；
因为data pump要传输数据到目标，所以需要配置rmthost和rmttrail指定目标主机和队列信息

————————————————————————————————————————————————————————————

（原原库）目标数据库操作：

11. 创建目标数据库的replicate进程

GGSCI (11g) 6> add rep repb, exttrail /home/oracle/ogg/dirdat/rb, nodbcheckpoint
REPLICAT added.

参数说明：

repa为进程名，一般为rep开头表示是replicat进程，后面可以加1-2位字符标识，一般与ext进程对应；
exttrail表示要抽取的数据队列，注意是目标端的队列位置；
nodbcheckpoint表示不使用数据库检查点。

GGSCI (11g) 17> edit param repb -- repb文件添加内容显示如下

GGSCI (11g) 20> view param repb

reperror default,abend
discardfile /home/oracle/ogg/dirrpt/repb.dsc,append, megabytes 10
assumetargetdefs
dynamicresolution
map oggdemo.oggdemo, target oggdemo.oggdemo;

ok，至此双向复制已经配置完成
