配置数据库环境、goldengate用户,安装goldengate等操作,参考不使用数据泵完成Oracle-Oracle的双向复制所需的配置:--我这里只配置同步test用户的 test1表。
1.主库的配置: #####配置Extract
按顺序执行以下操作:
add extract ext1,tranlog, begin now
add exttrail /u01/ogg/dirdat/lt, extract ext1

edit params ext1
在打开的编辑窗口写入以下:----这里使用为OGG创建的用户来登陆,同时要注意路径的对照。
extract ext1
userid ogg, password ogg
rmthost 192.168.1.213, mgrport 7809
rmttrail /u01/ogg/dirdat/lt
table test.*;
#####配置Replicat
edit params ./GLOBAL
在编辑窗口输入以下两行:
GGSCHEMA ogg
CHECKPOINTTABLE ogg.checkpoint

dblogin userid ogg,password ogg
add checkpointtable ogg.checkpoint
add replicat rep2,exttrail /u01/ogg/dirdat/at, checkpointtable ogg.checkpoint

edit params rep2
在弹出编辑窗口输入:---我这里只设置了同步test用户的test1表--这里的用户和表名在下一步的测试中再建立。
可以使用handlecollisions参数,避免主库与目标库所需要同步的表中数据不一致导致的接收进程挂起。
replicat rep2
handlecollisions
ASSUMETARGETDEFS
userid ogg,password ogg
discardfile /u01/ogg/dirdat/rep2_discard.txt,append, megabytes 10
map test.test1, target test.test1;

配置完成后的进程如下:--注意我这里的进程状态是启动后的。--建议主库及目标库都配置进程完成后再启动。

2.目标库的配置 #####配置Replicat
edit params ./GLOBAL
在编辑窗口输入以下两行:
GGSCHEMA ogg
CHECKPOINTTABLE ogg.checkpoint
逐次输入以下命令:
dblogin userid ogg,password ogg
add checkpointtable ogg.checkpoint
add replicat rep1,exttrail /u01/ogg/dirdat/lt, checkpointtable ogg.checkpoint

edit params rep1
在弹出编辑窗口输入以下:---我这里只设置了同步test用户的test1表--这里的用户和表名在下一步的测试中再建立。
replicat rep1
handlecollisions
ASSUMETARGETDEFS
userid ogg,password ogg
discardfile /u01/ogg/dirdat/rep1_discard.txt,append, megabytes 10
map test.test1, target test.test1;

#####配置Extract
按顺序执行以下命令:
add extract ext2,tranlog, begin now
add exttrail /u01/ogg/dirdat/at, extract ext2

edit params ext2
在打开的编辑窗口写入:
extract ext2
TRANLOGOPTIONS EXCLUDEUSER ogg
userid ogg, password ogg
rmthost 192.168.1.211, mgrport 7809
rmttrail /u01/ogg/dirdat/at
table test.*;
配置完成后的进程如下:--注意我这里的进程状态是启动后的。
