1.刪除源端數(shù)據(jù)庫的EXTRACT進程:
GGSCI (crm_master) 4> dblogin userid ogg,password OC8rGBIjkBG
Successfully logged into database.
GGSCI (crm_master) 5> delete extract EXTND
Deleted EXTRACT EXTND.
GGSCI (crm_master) 6> info all

MANAGER    RUNNING                             
EXTRACT     RUNNING     DPEND       00:00:00      00:00:06   
GGSCI (crm_master) 7> add exttrail ./gglog/nd,extract EXTND,megabytes 1000

GGSCI (crm_master) 8> ADD EXTTRAIL /oradata/gglog/nd, EXTRACT EXTND

EXTRACT     RUNNING     EXTND       00:07:46      00:00:01   
GGSCI (crm_master) 12>

2.進看源端數(shù)據(jù)庫的Trail文件號

[oracle@node1 ogg]$ ll ../gglog/
total 724
-rw-rw-rw- 1 oracle oinstall 737414 Jul 27 14:34 nd000000
[oracle@node1 ogg]$ 

3.在目標端數(shù)據(jù)庫指定Trail號

GGSCI (crm_slave) 5> alter REPLICAT repl extseqno 000, extrba 0        
REPLICAT altered.
GGSCI (crm_slave) 6> start repl
Sending START request to MANAGER ...
REPLICAT REPL starting
GGSCI (crm_slave) 7> info all
Program     Status      Group       Lag at Chkpt  Time Since Chkpt
MANAGER  RUNNING                                
REPLICAT    RUNNING     REPL        00:00:00      00:00:00   
GGSCI (crm_slave) 8>
