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/102/db_1/network/admin/listener.ora.rac1 # Generated by Oracle configuration tools. LISTENER_RAC1 = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521)(IP = FIRST)) (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.141)(PORT = 1521)(IP = FIRST)) ) ) SID_LIST_LISTENER_RAC1 = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /opt/oracle/102/db_1) (PROGRAM = extproc) ) (SID_DESC = (GLOBAL_DBNAME = +ASM) (ORACLE_HOME = /opt/oracle/102/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 10.2.0.1.0 - Production on Thu Jun 2 16:01:51 2016 Copyright (c) 1982, 2005, Oracle. All rights reserved. Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production With the Partitioning, Real Application Clusters, OLAP and Data Mining options SQL> conn sys/111111@192.168.1.142:1521/+ASM as sysdba Connected.
源端:
2.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,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$database; 必须是yes
4.Goldengate同步用户，我默认用system,避免权限纠结..
5.进入./ggsci 打开要同步的表的附件日志信息
GGSCI (rac1) 3> dblogin userid system@rac1,password 111111 或者 GGSCI (rac1) 3> dblogin userid system@192.168.1.141:1521/rac,password 111111
--添加附加日志的表
Add trandata gg.t1 或 gg.*
6.此步骤添加抓取进程，和传输进程,wan代表抓取进程,pwan代表传输进程
GGSCI (rac1) 8> edit param wan GGSCI (rac1) 8> view param wan EXTRACT WAN USERID wan@192.168.1.141:1521/rac,PASSWORD wan --登录的用户 TRANLOGOPTIONS ASMUSER sys@ASM,ASMPASSWORD 111111 --登录asm的 EXTTRAIL ./dirdat/et --抓取的数据放这里 TABLE wan.t1; --抓取的表 GGSCI (rac1) 8> Add Extract wan, TranLog, Begin Now threads 2 --rac有几个threads 2 就写几个 GGSCI (rac1) 8> Add ExtTrail ./dirdat/et, Extract wan, Megabytes 5 --建立./dirdat/et文件为5m GGSCI (rac1) 10> edit param pwan GGSCI (rac1) 11> view param pwan EXTRACT pwan RMTHOST 192.168.1.105,MGRPORT 7809,COMPRESS --传输给目标数据库服务器 RMTTRAIL ./dirdat/ww --远程目标存放的数据文件 passthru TABLE wan.t1; GGSCI (rac1) 11> Add Extract pwan, ExtTrailSource ./dirdat/et --传输进程pwan,提取的数据文件路径 GGSCI (rac1) 11> Add RmtTrail ./dirdat/ab, Extract psalesab, Megabytes 5 --建立目标数据库的数据文件./dirdat/ab为5m
GGSCI (rac1) 12> start extract * --启动建立好的进程 GGSCI (rac1) 12> info all Program Status Group Lag Time Since Chkpt MANAGER RUNNING EXTRACT RUNNING PWAN 00:00:00 00:00:06 EXTRACT RUNNING WAN 00:00:00 00:00:08
view report wan log --如果不能启动，用此命令查看日志
目标端
说明：目标端创建个写入进程,我命名为rwan
1.安装 Goldengate
tar xvf xxxxxx.tar.gz
cd xxxx
[oracle@rac1 oracle]$ ./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) 5> edit param mgr GGSCI (gg) 5> view param mgr port 7809 GGSCI (gg) 5> start mgr GGSCI (gg) 5> 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) 8> view param rwan replicat rwan userid system,password 111111 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。
