本文記錄了配置oracle和sqlserver資料同步的關鍵步驟，只為備忘！

測試環境：
oracle10.2.0.1
sqlserver2005(SQLServer2005SP3-KB955706-x86-CHS.exe)

oracle->sqlserver同步：

oracle和sqlserver中分別建一張測試表(表必須有主鍵)
oracle:create table n (id number(10) primary key)
sqlserver:create table n (id int primary key)

oracle:
ggsci>edit param mgr
port 7809

ggsci>dblogin userid ggs,password ggs
ggsci>add trandata test.n
ggsci>edit param eiexaa
extract eiexaa
userid ggs,password ggs
exttrail ./dirdat/dd
table test.n;

ggsci>edit param epmpaa
extract epmpaa
passthru
rmthost 192.168.126.131,mgrport 7809
rmttrail ./dirdat/dd
table test.n;

ggsci>add extract eiexaa,tranlog,begin now
ggsci>add exttrail ./dirdat/dd,extract eiexaa,megabytes 5
ggsci>add extract epmpaa,exttrailsource ./dirdat/dd
ggsci>add rmttrail ./dirdat/dd,extract epmpaa,megabytes 5

sqlserver:
ggsci>edit param mgr
port 7809

ggsci>sourcedb ggsdb dblogin userid ggs,password ggs
(ggsdb為系統DSN名)
ggsci>edit param rorabb
replicat rorabb
sourcedb ggsdb userid ggs,password ggs
handlecollisions
ASSUMETARGETDEFS
DISCARDFILE ./dirrpt/rorabb.dsc,PURGE
map test.n, target n;

ggsdb資料庫建立ggs_checkpoint表
ggsci>add replicat rorabb,checkpointtable ggs_checkpoint,exttrail ./dirdat/dd

sqlserver->oracle同步：

oracle和sqlserver中分別建一張測試表(表必須有主鍵)
oracle:create table m (id number(10) primary key)
sqlserver:create table m (id int primary key)

sqlserver:
ggsci>sourcedb ggsdb dblogin userid ggs,password ggs
ggsci>add trandata m
ggsci>edit param eiexbb
extract eiexbb
sourcedb ggsdb userid ggs,password ggs
exttrail ./dirdat/bb
TRANLOGOPTIONS MANAGESECONDARYTRUNCATIONPOINT
table m;

ggsci>edit param epmpbb
extract epmpbb
passthru
rmthost 192.168.126.1,mgrport 7809
rmttrail ./dirdat/bb
table m;

ggsci>add extract eiexbb,tranlog,begin now
ggsci>add exttrail ./dirdat/bb,extract eiexbb,megabytes 5
ggsci>add extract epmpbb,exttrailsource ./dirdat/bb
ggsci>add rmttrail ./dirdat/bb,extract epmpbb,megabytes 5

oracle:
ggsci>dblogin userid ggs,password ggs
ggsci>edit param roradd
replicat roradd
userid ggs,password ggs
handlecollisions
ASSUMETARGETDEFS
DISCARDFILE ./dirrpt/roradd.dsc,PURGE
MAP dbo.m, TARGET test.m;

ggs使用者下建立ggs_checkpoint表
ggsci>add replicat roradd,checkpointtable ggs.ggs_checkpoint,exttrail ./dirdat/bb
