使用OGG,两个Oracle库之间单向同步数据
配置:源数据库100.100.100.21 实例名dbsid2 目标数据库100.100.100.41 实例名db1 实验目标:源数据库中
配置:源数据库100.100.100.21 实例名dbsid2
目标数据库100.100.100.41 实例名db1
实验目标:源数据库中的 scott用户 emp表同步到目标数据库 scott中的test表
安装包为文件ogg112101_fbo_ggs_Linux_x64_ora10g_64bit.zip
解压之后,然后再tar解压tar -xvf fbo_ggs_Linux_x64_ora10g_64bit.tar -C /Oracle/ogg/
Oracle GoldenGate在异种OS上同种DB之间的数据同步
GoldenGate将Oracle数据同步到GreenPlum
1. 源数据库(dbsid2)配置:
(1) 用户权限:grant dba to scott
(2) 打开归档模式
(3)附加日志:
alter database add supplemental log data;
alter database force logging;
(4)将目标数据库db1信息添加到 tnsnames.ora中
2. 目标数据库(db1)配置:
(1) scott用户建立空表test,,表结构和emp相同
(2) 打开归档模式
(3) 附加日志:
alter database add supplemental log data;
alter database force logging;
(4) 将源数据库(dbsid2)的信息添加到 tnsnames.ora中
3. 源数据库服务器 goldengate安装
(1) 解压到/oracle/ogg目标下面
(2) 运行./ggsci
(3) 新建子目录: GGSCI (host2) 1> create subdirs
Creating subdirectories under current directory /oracle/ogg
Parameter files /oracle/ogg/dirprm: already exists
Report files /oracle/ogg/dirrpt: created
Checkpoint files /oracle/ogg/dirchk: created
Process status files /oracle/ogg/dirpcs: created
SQL script files /oracle/ogg/dirsql: created
Database definitions files /oracle/ogg/dirdef: created
Extract data files /oracle/ogg/dirdat: created
(4) 配置字符管理的Port参数
GGSCI (host2) 6> edit params mgr
输入: PORT 7809 然后保存
检查输入情况:
GGSCI (host2) 7> view params mgr
PORT 7809
(5) 启动Start mgr:
GGSCI (host2) 8> start mgr
MGR is already running.
GGSCI (host2) 9> info mgr
Manager is running (IP port host2.7809).
4. 目标数据库服务器 goldengate安装(和源目标服务器相同)
(1) 解压到/oracle/ogg目标下面
(2) 运行./ggsci
(3) 新建子目录: GGSCI (host2) 1> create subdirs
Creating subdirectories under current directory /oracle/ogg
Parameter files /oracle/ogg/dirprm: already exists
Report files /oracle/ogg/dirrpt: created
Checkpoint files /oracle/ogg/dirchk: created
Process status files /oracle/ogg/dirpcs: created
SQL script files /oracle/ogg/dirsql: created
Database definitions files /oracle/ogg/dirdef: created
Extract data files /oracle/ogg/dirdat: created
(4) 配置字符管理的Port参数
GGSCI (host2) 6> edit params mgr
输入: PORT 7809 然后保存
检查输入情况:
GGSCI (host2) 7> view params mgr
PORT 7809
(4) 启动Start mgr:
GGSCI (host2) 8> start mgr
MGR is already running.
GGSCI (host2) 9> info mgr
Manager is running (IP port host2.7809).
5. 配置源数据库服务器(dbsid2)传输进程extract
(1)添加名字为source1的进程
GGSCI (host2) 19> add extract source1,sourceistable
EXTRACT added.
(3) 修改source1参数
GGSCI (host2) 20> edit params source1
添加如下,并且保存
extract source1
setenv (NLS_LANG=AMERICAN_AMERICA.AL32UTF8)
userid scott,password tiger
