RAC环境下配置OGG同步

在本文中，介绍了rac环境下配置ogg的单向同步；在配置过程中，2节点的rac数据库做为source端，单实例的数据库作为target端，下面是具体的环境介绍!
source端：
操作系统版本：rhel5.4 64bit
数据库版本：11.2.0.3 64bit
ogg版本：fbo_ggs_Linux_x64_ora10g_64bit.tar
rac数据库名：rac.yang.com
public ip:192.168.1.41/24,192.168.1.42/24
private ip:192.168.122.41/24,192.168.122.42/24
vip:192.168.1.141/24,192.168.1.142/24
scan名：rac-scan.yang.com
scan-ip:192.168.1.144/24,192.168.1.145/24,192.168.1.146/24

target端：
操作系统版本：rhel5.4 64bit
数据库版本：11.2.0.3 64bit
ogg版本：fbo_ggs_Linux_x64_ora10g_64bit.tar
数据库名：dg3.yang.com
ip:192.168.1.63/24

一：首先在两个rac节点上配置ASM动态注册,11g的监听器引入了endpoints_listener.ora文件管理

[grid@rac1 rac1]$ srvctl status listener
Listener LISTENER is enabled
Listener LISTENER is running on node(s): rac2,rac1

[grid@rac1 rac1]$ lsnrctl services

  )

二：acfs上安装ogg，acfs用来存放ogg的安装目录，便于集群件的共享，在10g上部署可以选择ocfs2，acfs的部署过程参考：http://ylw6006.blog.51cto.com/470441/925545

[root@rac1 ~]# ll -d /vol2/
drwxrwx--- 4 root asmadmin 4096 Jul  9 09:38 /vol2/
[root@rac1 ~]# id oracle
uid=501(oracle) gid=500(oinstall) groups=500(oinstall),502(asmdba),504(dba),505(oper)
[root@rac1 ~]# chown -R oracle.asmadmin /vol2/  （节点2做同样的操作）

三：rac数据库上进行配置，创建用户，授权，运行执行序列号和ddl复制的相关脚本等

[oracle@rac1 ogg]$ sqlplus sys/123456@rac as sysdba
SQL> select instance_name from v$instance;

INSTANCE_NAME
----------------
rac2

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

SQL> grant connect,resource,dba to ogg;
Grant succeeded.

SQL> @sequence.sql

SQL> alter database  add supplemental log data;
Database altered.

SQL> alter database  add supplemental log data (primary key) columns;
Database altered.

SQL> alter database  add supplemental log data (foreign key) columns;
Database altered.

SQL> alter database  add supplemental log data (unique) columns;
Database altered.

SQL> alter system archive log current;
System altered.

SQL> grant execute on utl_file to ogg;
Grant succeeded.

SQL> @marker_setup.sql
SQL> @ddl_setup.sql
SQL> @role_setup.sql
SQL> grant ggs_ggsuser_role to ogg;
SQL> @ddl_enable.sql
SQL> @ddl_pin ogg

四：在source端配置extract group

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

SQL> grant connect,resource to test;
Grant succeeded.

GGSCI (rac1.yang.com) > dblogin userid ogg,password ogg
Successfully logged into database.

GGSCI (rac1.yang.com) > add extract testext,tranlog,begin now,threads 2
EXTRACT added.

GGSCI (rac1.yang.com) > add exttrail /vol2/ogg/dirdat/et, extract testext
EXTTRAIL added.

GGSCI (rac1.yang.com) > view params testext
EXTRACT testext
SETENV (ORACLE_HOME = "/u01/app/oracle/product/11.2.0/db1")
USERID ogg@rac, PASSWORD ogg
TRANLOGOPTIONS ASMUSER sys@ASM,ASMPASSWORD 123456
THREADOPTIONS MAXCOMMITPROPAGATIONDELAY 20000
EXTTRAIL /vol2/ogg/dirdat/et
DYNAMICRESOLUTION
DDL INCLUDE ALL
TABLE test.*;

五：在source端配置data pump extract group

GGSCI (rac1.yang.com) > add extract testpump,exttrailsource /vol2/ogg/dirdat/et,begin now
EXTRACT added.

GGSCI (rac1.yang.com) > add rmttrail /vol2/ogg/dirdat/rt,extract testpump
RMTTRAIL added.

GGSCI (rac1.yang.com) > view params  testpump
EXTRACT testpump
RMTHOST 192.168.1.63, MGRPORT 7809
RMTTRAIL /vol2/ogg/dirdat/rt
PASSTHRU
TABLE test.*

六：target端配置，这里要保证在tnsnames.ora文件中配置了dg3连接串，同时建立/vol2/ogg/dirdat/rt目录，并授权；在这里未测试过target端和source使用不同的目录是否可行！

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

SQL> grant connect,resource,dba to ogg;
Grant succeeded.

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

SQL> grant connect,resource to test;
Grant succeeded.

GGSCI (dg3.yang.com) > add replicat testrpt,exttrail /vol2/ogg/dirdat/rt,nodbcheckpoint
REPLICAT added.

GGSCI (dg3.yang.com) > view params testrpt
REPLICAT testrpt
SETENV (ORACLE_HOME = "/u01/app/oracle/product/11.2.0/db1")
USERID ogg@dg3,PASSWORD ogg
ASSUMETARGETDEFS
HANDLECOLLISIONS
REPERROR (DEFAULT, DISCARD)
DDLERROR DEFAULT DISCARD
DDLOPTIONS REPORT
DISCARDFILE /vol2/ogg/repsz.dsc,append,megabytes 100
MAP test.*, TARGET test.*;

七：启动各进程

GGSCI (rac1.yang.com) > start testext
Sending START request to MANAGER ...
EXTRACT TESTEXT starting

GGSCI (rac1.yang.com) > start testpump
Sending START request to MANAGER ...
EXTRACT TESTPUMP starting

GGSCI (rac1.yang.com) > info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt
MANAGER     RUNNING
EXTRACT     RUNNING     TESTEXT     00:00:00      00:19:49
EXTRACT     RUNNING     TESTPUMP    00:00:00      00:03:24

GGSCI (dg3.yang.com) > start testrpt
Sending START request to MANAGER ...
REPLICAT TESTRPT starting

GGSCI (dg3.yang.com) > info all
Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING
REPLICAT    RUNNING     TESTRPT     00:00:00      00:00:02

进程安排在最后启动，在启动source端的pump进程之前，如果target端的replicat进程未启动，则会报如下错误：
2012-07-15 13:56:14  ERROR   OGG-01033  There is a problem in network communication, a remote file problem, encryption keys for target and source do not match (if using ENCRYPT) or an unknown error. (Remote file used is /vol2/ogg/dirdat/rt000000, reply received is Could not create /vol2/ogg/dirdat/rt000000).

SQL> select * from t1;

        ID NAME
---------- ----------
         1 one

总结：rac环境下配置ogg，基本同单实例无异！重点需要注意的地方有以下几点!
1：使用ASM存储，需要先配置ASM实例的静态注册，同时在tnsnames.ora文件中配置连接串
2：在配置exttract进程中，注意需要配置TRANLOGOPTIONS 参数，输入连接asm实例的凭证
3：在配置exttract进程中，添加tranlog的时候，需要写thread 2
4: 注意进程的启动顺序，先是source和target端的mgr进程，其次是source端的extract进程，target端的replicat进程，最后是source端的extract pump进程

本文不包含source端的failover功能，后续将继续测试,敬请关注！
