简介: <div id="content" class="bigfont mycontent" style="zoom:1; line-height:23px; font-size:14px; margin:18px 28px; font-family:'lucida Grande',Verdana,'Microsoft YaHei'; clear:both; min-height:200px;

Install and Configure Goldengate on RAC 10g

以前写过几篇关于OGG(Oracle GlodenGate)部署的文章,是关于单实例到单实例,具体内容可参考:
Install and simple configure Oracle GoldenGate
Configure Oracle GoldenGate Active-to-Active

今天测试了一下从RAC 到 单实例的简单部署,做简要记录如下:

测试环境:
source 端:
操作系统版本:rhel4.8 32bit
数据库版本:10.2.0.4 32bit
ogg 版本:fbo_ggs_Linux_x86_ora10g_32bit.tar
RAC 数据库名:honcho 实例:honcho1、honcho2
Hostname: xhz1、xhz2
Public IP: 192.168.0.166 、192.168.0.168
Private IP:10.10.10.166 、10.10.10.168
VIP: 192.168.0.167 、192.168.0.169

target 端:
操作系统版本:rhel4.8 32bit
数据库版本:10.2.0.1 32bit
ogg 版本:fbo_ggs_Linux_x86_ora10g_32bit.tar
Database Name:honcho
IP:192.168.0.99

1.在RAC节点上配置ASM实例监听动态注册,确保goldengate用户能够连接到所有的ASM实例。

[oracle@xhz1 admin]$ cat listener.ora
# listener.ora.xhz1 Network Configuration File: /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora.xhz1
# Generated by Oracle configuration tools.
LISTENER_XHZ1 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = xhz1-vip)(PORT = 1521)(IP = FIRST))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.166)(PORT = 1521)(IP = FIRST))
    )
  )

SID_LIST_LISTENER_XHZ1 =
  (SID_LIST =
    (SID_DESC =

      (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = +ASM)
      (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
      (SID_NAME = +ASM1)
    )
  )

[oracle@xhz1 admin]$ cat tnsnames.ora

LISTENERS_HONCHO =
  (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = xhz1-vip)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = xhz2-vip)(PORT = 1521))
  )

HONCHO1 = 
  (description_list =
    (DESCRIPTION=
       (ADDRESS_LIST=
         (LOAD_BALANCE=OFF)
         (FAILOVER=ON)
         (ADDRESS=(PROTOCOL=TCP)(Host=192.168.0.167)(Port=1521))
         (ADDRESS=(PROTOCOL=TCP)(Host=192.168.0.169)(Port=1521))
       )
       (CONNECT_DATA=
          (SERVICE_NAME=honcho1)
          (server=dedicated)
          (FAILOVER_MODE=
            (RETRIES=30)
            (DELAY=5)
            (TYPE=SELECT)
          )
        )
    )
  )
  
HONCHO2 = 
  (description_list =
    (DESCRIPTION=
       (ADDRESS_LIST=
         (LOAD_BALANCE=OFF)
         (FAILOVER=ON)
         (ADDRESS=(PROTOCOL=TCP)(Host=192.168.0.169)(Port=1521))
         (ADDRESS=(PROTOCOL=TCP)(Host=192.168.0.167)(Port=1521))
       )
       (CONNECT_DATA=
          (SERVICE_NAME=honcho2)
          (server=dedicated)
          (FAILOVER_MODE=
            (RETRIES=30)
            (DELAY=5)
            (TYPE=SELECT)
          )
        )
    )
  )
  
HONCHO =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = xhz1-vip)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = xhz2-vip)(PORT = 1521))
    (LOAD_BALANCE = yes)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = honcho)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

ASM =  
 (DESCRIPTION =  
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.166)(PORT = 1521))  
    (CONNECT_DATA =  
      (SERVER = DEDICATED)  
      (SERVICE_NAME = +ASM)  
      (SID_NAME = +ASM1)  
    )  
  )

在节点2上做类似的配置,然后重启监听:

[oracle@xhz1 admin]$ srvctl stop listener -n xhz1
[oracle@xhz1 admin]$ srvctl stop listener -n xhz2
[oracle@xhz1 admin]$ srvctl start listener -n xhz1
[oracle@xhz1 admin]$ srvctl start listener -n xhz2
[ oracle @ xhz1   admin ]$  export   ORACLE_SID =+ ASM1
[

2.在source和target端部署ogg,由于前面几个文章里关于部署ogg做个介绍,这里不做太多解释:

2.1 创建安装路径:

[oracle@xhz1 ~]$ mkdir -p /u01/app/oracle/ogg

2.2 配置环境变量:

[oracle@xhz1 ~]$ cat .bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH
unset USERNAME

export ORACLE_SID=honcho1
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORA_CRS_HOME=$ORACLE_BASE/product/10.2.0/crs_1
export PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:$ORACLE_BASE/ogg:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_BASE/ogg:/lib:/usr/lib
export OGG=/u01/app/oracle/ogg

umask 022

2.3 解压安装包到安装路径:

[oracle@xhz1 software]$ tar xvf fbo_ggs_Linux_x86_ora10g_32bit.tar -C /u01/app/oracle/ogg

2.4 启动ggsci并创建目录,然后进行必要的设置,启动manager

[oracle@xhz1 ogg]$ ldd ggsci

EXTTRAIL added.

GGSCI (xhz1) 4> edit params testext

GGSCI (xhz1) 5> view params testext

EXTRACT testext  
SETENV (ORACLE_HOME = "/u01/app/oracle/product/10.2.0/db_1")

4.在source端配置data pump extract group

GGSCI (xhz1) 6> add extract testpump,exttrailsource /u01/app/oracle/ogg/dirdat/et,begin now
EXTRACT added.

GGSCI (xhz1) 7> add rmttrail /u01/app/oracle/ogg/dirdat/et,extract testpump

RMTTRAIL /u01/app/oracle/ogg/dirdat/et  
PASSTHRU  
TABLE test.*;

5.target端配置,这里要保证在tnsnames.ora文件中配置了honcho连接串,这里路径是一直的,可以根据自己需要配置不同路径亦可。

GGSCI (honcho) 1> add replicat testrpt,exttrail /u01/app/oracle/ogg/dirdat/et,nodbcheckpoint
REPLICAT added.

GGSCI (honcho) 2> edit params testrpt

GGSCI (honcho) 3> view params testrpt

REPLICAT testrpt  
SETENV (ORACLE_HOME = "/u01/app/oracle/product/10.2.0.1/db1")  
USERID ogg@honcho,PASSWORD ogg  
ASSUMETARGETDEFS  
HANDLECOLLISIONS  
REPERROR (DEFAULT, DISCARD)  
DDLERROR DEFAULT DISCARD  
DDLOPTIONS REPORT  
DISCARDFILE /u01/app/oracle/ogg/repsz.dsc,append,megabytes 100  
MAP test.*, TARGET test.*;

6.启动extract和replicat 进程:

GGSCI (honcho) 4> start testrpt

Sending START request to MANAGER ...
REPLICAT TESTRPT starting

GGSCI (honcho) 5> info all

Program     Status      Group       Lag           Time Since Chkpt

GGSCI (xhz1) 10> start testext

GGSCI (xhz1) 11> start testpump

Sending START request to MANAGER ...
EXTRACT TESTPUMP starting

GGSCI (xhz1) 12> info all

EXTRACT     RUNNING     TESTPUMP    00:00:00      00:00:04

7.测试
在节点1上创建测试表:

SQL select   instance_name   from   v $ instance ;
 
INSTANCE_NAME
--------------
--
honcho1

 
SQL conn   test / test
Connected .
SQL create   table   honcho   ( id   number , name   varchar2 ( 20 )) ;
 
Table   created .
 
SQL begin  
  
2      for   i   in   1..100   loop
  
3       insert   into   honcho   values   ( i , ' honcho ' ) ;
  
4      end   loop ;
  
5      commit ;
  
6    end ;
  
7   /
 
PL / SQL   procedure   successfully   completed .
 
SQL select   count ( * )   from   honcho ;
 
  
COUNT ( * )
--------
--
       100

在目标上查看:

SQL select   instance_name   from   v $ instance ;
 
INSTANCE_NAME
--------------
--
honcho

 
SQL conn   test / test
Connected .
SQL select   count ( * )   from   honcho ;
 
  
COUNT ( * )
--------
--
       100

在节点2上添加新数据:

SQL select   instance_name   from   v $ instance ;
 
INSTANCE_NAME
--------------
--
honcho2

 
SQL conn   test / test
Connected .
SQL begin
  
2      for   i   in   101..200   loop
  
3       insert   into   honcho   values   ( i , ' honcho ' ) ;
  
4       end   loop ;
  
5       commit ;
  
6    end ;
  
7   /
 
PL / SQL   procedure   successfully   completed .
 
SQL select   count ( * )   from   honcho ;
 
  
COUNT ( * )
--------
--
       200

在目标库上查看数据:

SQL> select instance_name from v$instance;

INSTANCE_NAME
----------------
honcho

SQL> conn test/test
Connected.
SQL> select count(*) from honcho;

  COUNT(*)
----------
       200

从测试数据可以查到在节点1和节点2上变更数据都可以同步到目标端。

总结:rac环境下配置ogg,基本同单实例无异!需要注意的地方有以下几点!
1:只需要在一个节点部署ogg即可,但是需要保证ogg可以识别到其他节点的redo或者archivelog,如果归档实在本地,可以通过NFS来实现访问;
2: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;
3: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;
4:在配置exttract进程中,添加tranlog的时候,需要写thread n,n代表节点数;
5: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。
