基于Linux环境使用ogg19版本从oracle 19c ADG备库远程同步数据

基于Linux环境使用ogg19版本对oracle 19c同步数据

在之前一期文章中提到了 "基于Windows测试OGG远程从ADG备库抽取数据"。文章的最后提到了在Linux环境测试失败的情况，在这一期的文章中测试了Linux环境，但是使用的数据库版本和OGG版本均是19的。之前那一期的数据库版本是11.2.0.4 ，ogg版本是12.1.0.1。有可能是因为版本的问题导致。

此次案例测试中，数据可以成功抽取成功。

说明：代码有些部分对不上，是因为测试过程种来回切换，有些关键字也虚拟模糊了，步骤和方法是正确的。

静默安装OGG

复制代码

./runInstaller -silent -nowait -responseFile /so/fbo_ggs_Linux_x64_shiphome/Disk1/response/oggcore.rsp

源端和目标端创建OGG同步用户

复制代码

源端(10.120.84.25)和目标端创建同步管理账号

创建OGG登录别名

复制代码

--创建用户凭证别名
add credentialstore
--创建到源端的登录别名
--登录源端主库别名
alter credentialstore add user ggs@xxx, password Caecaodb2017 alias xx
alter credentialstore add user ggs@xxx, password Caecaodb2017 alias xx
alter credentialstore add user ggs@xxx, password Caecaodb2017 alias xxx

--登录源端备库别名
alter credentialstore add user ggs@xxx, password Caecaodb2017 alias xxx
alter credentialstore add user ggs@xxx, password Caecaodb2017 alias xxx
alter credentialstore add user ggs@xxx, password Caecaodb2017 alias xxx

--目标端登录别名
alter credentialstore add user ggs@xxx, password Caecaodb2017 alias xx

--测试验证
dblogin useridalias xxx

添加抽取进程

复制代码

add extract escims3, tranlog, begin now, threads 1    <<<<< 如果是RAC，修改为2
add exttrail ./dirdat/e3, extract escims3, megabytes 50

edit params escims3

extract escims3
SETENV (TNS_ADMIN='/app/oracle/product/19.3.000/db_home/network/admin')
userid ggs@ora105, password xxxx
exttrail ./dirdat/e3
discardfile ./dirrpt/escims3.dsc, append, megabytes 20
discardrollover at 05:30 on monday
warnlongtrans 3h, checkinterval 10m
tranlogoptions logretention enabled
tranlogoptions dblogreader
tranlogoptions minefromactivedg
--tables
table ggs.testtab;

添加应用进程(有些关键字做了虚拟)

复制代码

dblogin useridalias xxxx
add checkpointtable ggs.xxxx

--非并行进程
add replicat rs3t, exttrail ./dirdat/e3, checkpointtable ggs.xxxx

edit param rs3t

replicat rs3t
useridalias xxxx
discardfile ./dirrpt/rs3t.dsc, append, megabytes 100
discardrollover at 05:30 on monday
--tables
gettruncates
map ggs.testtab ,target maintain.testtab;

数据初始化的方式有2种

复制代码

>>>>> 数据初始化 数据泵初始化方式
SET NUMWIDTH 20;   
select current_scn from v$database;

 (根据同步当时获取的值填写)

目标端 10.128.103.54 导入数据
