Goldengate 部署oracle10g在 rac asm环境，完整教程

前言

Goldengate再rac 环境部署，和单机部署区别还是有点大，主要存在环境上.

环境

oracle10g ,sid=rac

准备工作

1.在rac节点，配置监听动态注册,确保goldengate用户能够连接实例。安装部分分为源端和目标端

节点一配置:

[oracle@rac1 admin]$ cat listener.ora
# listener.ora.rac1 Network Configuration File: /opt/oracle//db_1/network/admin/listener.ora.rac1
# Generated by Oracle configuration tools.

LISTENER_RAC1 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = )(IP = FIRST))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.141)(PORT = )(IP = FIRST))
    )
  )

SID_LIST_LISTENER_RAC1 =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /opt/oracle//db_1)
      (PROGRAM = extproc)
    )
      (SID_DESC =
      (GLOBAL_DBNAME = +ASM)
      (ORACLE_HOME = /opt/oracle//db_1)
      (SID_NAME = +ASM1)
    )
 )

[oracle@rac1 admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /opt/oracle/102/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

RAC =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = rac2-vip)(PORT = 1521))
    (LOAD_BALANCE = yes)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = rac)
    )
  )

LISTENERS_RAC =
  (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = rac2-vip)(PORT = 1521))
  )

RAC2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = rac2-vip)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = rac)
      (INSTANCE_NAME = rac2)
    )
  )

RAC1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = rac)
      (INSTANCE_NAME = rac1)
    )
  )

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

ASM =
 (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.141)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = +ASM)
      (SID_NAME = +ASM1)
    )
  )

节点二相同配置，记得修改对应参数

重启监听

[oracle@rac1 admin]$ srvctl stop listener -n rac1
[oracle@rac1 admin]$ srvctl stop listener -n rac2
[oracle@rac1 admin]$ srvctl start listener -n rac1
[oracle@rac1 admin]$ srvctl start listener -n rac2

检查asm实例

[oracle@rac1 admin]$ export ORACLE_SID=+ASM1
[oracle@rac1 admin]$ sqlplus / as sysdba

SQL*Plus: Release 10.2.0.1. - Production on Thu Jun  ::

SQL> conn sys/@192.168.1.142:/+ASM  as sysdba
Connected.

源端:

2.安装 Goldengate

tar xvf xxxxxx.tar.gz

cd xxxx

[oracle@rac1 oracle]$ ./ggsci
GGSCI (rac1) > create subdirs

[oracle@gg gg]$ ./ggsci

配置gg的mgr端口,目标端也需要做同样的配置

GGSCI (gg) 5> edit param mgr
GGSCI (gg) 5> view param mgr
port 7809
GGSCI (gg) 5> start mgr
GGSCI (gg) 5> info mgr

--安装完毕

3.数据库的环境准备，需添加附加日志

原数据库Oracle
----》alter database add supplemental log data;  //添加附加信息
Alter system switch logfile;
查看 select supplemental_log_data_min from v$database; 必须是yes

4.Goldengate同步用户，我默认用system,避免权限纠结..

5.进入./ggsci 打开要同步的表的附件日志信息

GGSCI (rac1) > dblogin userid system@rac1,password
或者
GGSCI (rac1) 3> dblogin userid system@192.168.1.141:/rac,password 111111
--添加附加日志的表
Add trandata gg.t1 或 gg.*

6.此步骤添加抓取进程，和传输进程,wan代表抓取进程,pwan代表传输进程

GGSCI (rac1) 8> edit param wan
GGSCI (rac1) 8> view param wan
EXTRACT WAN
USERID wan@192.168.1.141:1521/rac,PASSWORD wan --登录的用户
TRANLOGOPTIONS ASMUSER sys@ASM,ASMPASSWORD 111111  --登录asm的
EXTTRAIL ./dirdat/et      --抓取的数据放这里
TABLE wan.t1;   --抓取的表

GGSCI (rac1) 8> Add Extract wan, TranLog, Begin Now  threads 2  --rac有几个threads 2 就写几个
GGSCI (rac1) 8> Add ExtTrail ./dirdat/et, Extract wan, Megabytes 5  --建立./dirdat/et文件为5m

GGSCI (rac1) 10> edit param pwan
GGSCI (rac1) 11> view param pwan
EXTRACT pwan
RMTHOST 192.168.1.105,MGRPORT 7809,COMPRESS  --传输给目标数据库服务器
RMTTRAIL ./dirdat/ww  --远程目标存放的数据文件
passthru
TABLE wan.t1; 

GGSCI (rac1) 11> Add Extract pwan, ExtTrailSource ./dirdat/et   --传输进程pwan,提取的数据文件路径
GGSCI (rac1) 11> Add RmtTrail ./dirdat/ab, Extract psalesab, Megabytes 5 --建立目标数据库的数据文件./dirdat/ab为5m

GGSCI (rac1) > start extract *  --启动建立好的进程
GGSCI (rac1) > info all

Program     Status      Group       Lag           Time Since Chkpt

MANAGER     RUNNING
EXTRACT     RUNNING     PWAN        ::      ::
EXTRACT     RUNNING     WAN         ::      ::    

view report wan log  --如果不能启动，用此命令查看日志

目标端

说明：目标端创建个写入进程,我命名为rwan

1.安装 Goldengate

tar xvf xxxxxx.tar.gz

cd xxxx

[oracle@rac1 oracle]$ ./ggsci
GGSCI (rac1) 2> create subdirs

[oracle@gg gg]$ ./ggsci

配置gg的mgr端口,源端也需要做同样的配置

GGSCI (gg) > edit param mgr
GGSCI (gg) > view param mgr
port
GGSCI (gg) > start mgr
GGSCI (gg) > info mgr

配置检查数据一致性的表

编辑全局数据文件   //添加检查数据一致性的表
Edit params ./GLOBALS
CHECKPOINTTABLE system.checkpointtable
保存
创建表
Dblogin userid system, password oracle
Add checkpointtable

添加rwan配置文件

GGSCI (gg) > view param rwan

replicat rwan
userid system,password
HANDLECOLLISIONS
ASSUMETARGETDEFS
--ddl include all
--ddlerror default ignore retryop
discardfile ./dirrpt/rwan.dsc,append
map wan.t1, target chis.t1;

添加rwan进程

GGSCI (gg) 8> Add Replicat rwan, ExtTrail ./dirdat/ww

启动 start replicat rwan

GGSCI (gg) 9> info all

Program     Status      Group       Lag           Time Since Chkpt

MANAGER     RUNNING                                           

REPLICAT    RUNNING     RWAN        00:00:00      00:00:07

到此就配置成功了。

总结

源端数据库对某表，做了dll操作，目标端已打补丁的方式添加，添加后，需对rwan进程重启一次。

再配置过程中参考了如下文章:
