實驗環境：
源端、目標端：
DataBase：10.2.0.1.0
OS：OEL5.6
OGG：fbo_ggs_Linux_x86_ora11g_32bit
源端使用rman進行備份全庫：

源端數據庫查詢：

記錄此時非活動日志組的SCN，有多組的時候我們取最大的FIRST_CHANGE#，在這裡是484267。
將源端庫的init<SID>.ora發送到目標端：
SYS@ORCL>create pfile from spfile;
File created.
[oracle@edbjr2p1 dbs]$ scp initORCL.ora edbjr2p2:$ORACLE_HOME/dbs
oracle@edbjr2p2's password:

在目標端建立所有目錄，然後將備份傳過去：

然後recover數據庫到前邊我們記錄的SCN處：
RMAN>run
{
SET UNTIL SCN 484267;
RECOVER DATABASE;
}2> 3> 4> 5>
目標端查看此時SCN並打開數據庫：
SQL> SELECT CHECKPOINT_CHANGE#,CHECKPOINT_TIME FROM V$DATAFILE_HEADER;
CHECKPOINT_CHANGE# CHECKPOIN

484267 21-JUL-14
484267 21-JUL-14
484267 21-JUL-14
6 rows selected.
SQL> alter database open resetlogs;
Database altered.
目標端啟動Replicat進程：
GGSCI (edbjr2p2) 1>start repya ,afterscn 484267
此處使用的SCN是我們之前記錄的SCN。因為數據文件恢復到了這個SCN，rman保證了這個SCN之前的源端和目標端庫的數據一致性，OGG只要應用此SCN之後出現的數據變化即可。
