goldengate基于表復(fù)制

添加主進(jìn)程

GGSCI (ggate1) 2> edit params mgr

PORT 7809
PURGEOLDEXTRACTS /oracle/ggate/dirdat/mytest_xiuj/ex*, USECHECKPOINTS, MINKEEPDAYS 7

登錄到數(shù)據(jù)庫
GGSCI (ggate1) 3> dblogin userid ggate,password ggate
Successfully logged into database.

GGSCI (ggate1) 4> start mgr

2、配置抽了進(jìn)程

GGSCI (ggate1) 13> add trandata mytest.mytest_xiuj

Logging of supplemental redo data enabled for table MYTEST.MYTEST_XIUJ.

GGSCI (ggate1) 14> add extract exiuj,tranlog,begin now
EXTRACT added.

GGSCI (ggate1) 15> add exttrail /oracle/ggate/dirdat/mytest_xiuj/ex,extract exiuj
EXTTRAIL added.

GGSCI (ggate1) 17> edit params exiuj

extract exiuj
userid ggate,password ggate
exttrail /oracle/ggate/dirdat/mytest_xiuj/ex
table mytest.mytest_xiuj;

3、配置傳輸進(jìn)程

GGSCI (ggate1) 23> add extract pxiuj,exttrailsource /oracle/ggate/dirdat/mytest_xiuj/ex
EXTRACT added.

GGSCI (ggate1) 24> add rmttrail /u01/app/ggate/dirdat/mytest_xiuj/re,extract pxiuj
RMTTRAIL added.

GGSCI (ggate1) 25> edit params pxiuj

extract pxiuj
rmthost 192.168.92.191,mgrport 7809
passthru
rmttrail /u01/app/ggate/dirdat/mytest_xiuj/re
table mytest.mytest_xiuj;

4、配置復(fù)制進(jìn)程

GGSCI (ggate2) 3> dblogin userid ggate,password ggate
Successfully logged into database.

GGSCI (ggate2) 4> add checkpointtable chkxiuj

Successfully created checkpoint table CHKxiuj.

GGSCI (ggate2) 5> add replicat rxiuj,exttrail /u01/app/ggate/dirdat/mytest_xiuj/re,checkpointtable chkxiuj
REPLICAT added.

GGSCI (ggate2) 6> edit params rxiuj

replicat rxiuj
setenv ( NLS_LANG = "SIMPLIFIED CHINESE_CHINA.UTF8")                    --注意，本處不能少，因?yàn)槟繕?biāo)端與源端字符集不同
assumetargetdefs
HANDLECOLLISIONS
userid ggate,password ggate
discardfile /u01/app/ggate/dirdat/mytest_xiuj/rep1_discard.txt, append, megabytes 10
map mytest.mytest_xiuj, target receiver.mytest_xiuj;

--說明：
 
在配置goldengate時(shí)，要確定源端與目標(biāo)端的字符集是否相同
通過:
SQL> select userenv('language') from dual;
 
USERENV('LANGUAGE')
----------------------------------------------------
SIMPLIFIED CHINESE_CHINA.ZHS16GBK

而源端為："SIMPLIFIED CHINESE_CHINA.UTF8"，使目標(biāo)端與源端相同，否則在目標(biāo)端，會(huì)出現(xiàn)亂碼。所以在復(fù)制進(jìn)程中必須加一段設(shè)置環(huán)境的值：setenv ( NLS_LANG = "SIMPLIFIED CHINESE_CHINA.UTF8")

查詢導(dǎo)出字符集
select * from database_properties where property_name = 'NLS_CHARACTERSET'
