1、平臺環(huán)境
十年的威寧網(wǎng)站建設(shè)經(jīng)驗,針對設(shè)計、前端、開發(fā)、售后、文案、推廣等六對一服務(wù),響應(yīng)快,48小時及時工作處理。成都全網(wǎng)營銷的優(yōu)勢是能夠根據(jù)用戶設(shè)備顯示端的尺寸不同,自動調(diào)整威寧建站的顯示方式,使網(wǎng)站能夠適用不同顯示終端,在瀏覽器中調(diào)整網(wǎng)站的寬度,無論在任何一種瀏覽器上瀏覽網(wǎng)站,都能展現(xiàn)優(yōu)雅布局與設(shè)計,從而大程度地提升瀏覽體驗。創(chuàng)新互聯(lián)從事“威寧網(wǎng)站設(shè)計”,“威寧網(wǎng)站推廣”以來,每個客戶項目都認(rèn)真落實執(zhí)行。
Oracle:rhel6.7+Oracle11.2.0.4 ip:192.168.56.2
PostgreSQL:rhel7.2+Pg9.6.1 ip:192.168.56.25
Goldengate:Goldengate12.2.0.1 for oracle和Goldengate 12.2.0.1 for PostgreSQL
2、Ogg配置
Oracle端:
直接安裝goldengate for oracle 11g
配置環(huán)境變量
[oracle@rhel6 ogg]$ vi ~/.bash_profile #添加 export LD_LIBRARY_PATH=/ogg/lib:$LD_LIBRARY_PATH export PATH=/ogg:$PATH
配置Oracle數(shù)據(jù)庫

PostgreSQL端:
創(chuàng)建用于同步的數(shù)據(jù)庫、用戶和Schema,并創(chuàng)建測試表

解壓ogg
[pguser@rhel7 ogg]$ tar -xvf ggs_Linux_x64_PostgreSQL_64bit.tar
配置odbc數(shù)據(jù)源,goldengate 使用ODBC連接Postgres Database
[pguser@rhel7 ogg]$ pwd /ogg [pguser@rhel7 ogg]$ cat odbc.ini [ODBC Data Sources] GG_Postgres=DataDirect 9.6 PostgreSQL Wire Protocol [ODBC] IANAAppCodePage=106 InstallDir=/ogg [GG_Postgres] Driver=/ogg/lib/GGpsql25.so Description=DataDirect 9.6 PostgreSQL Wire Protocol Database=zhaoxu HostName=127.0.0.1 PortNumber=5432 LogonID=zhaoxu Password=zhaoxu
[ODBC Data Sources]里邊配置該ODBC的別名,本文件中也就是GG_Postgres 后邊的配置文件中的targetdb需要與這個對應(yīng)
[ODBC]:
IANAAppCodePage指的是字符集的設(shè)置 這里的106值得是UTF8,如果是4則為ISO-8859-1,注意這個應(yīng)該始終和postgres的字符集設(shè)置相同,不同字符集對應(yīng)的值見附件。
InstallDir對應(yīng)ogg的安裝目錄
[GG_Postgres]:這里的名稱對應(yīng)的是上邊ODBC的別名
Driver這里指向的是ogg安裝目錄下的lib/GGpsql25.so
Description是描述
Database填寫數(shù)據(jù)庫名稱
HostName填寫本機的hostname,可以解析的即可。
PosrNumber是postgres的監(jiān)聽端口。
LogonID填寫postgres的用戶名
password填寫postgres的密碼
配置環(huán)境變量
export LD_LIBRARY_PATH=/ogg/lib:$LD_LIBRARY_PATH export PATH=$PATH:/ogg export ODBCINI=/ogg/odbc.ini
配置Ogg

測試insert
