Initial Load
a
At Source Database Server
expdp parfile=expdp_additional_tables.par
Where expdp_additional_tables.par is a parameter
file, its contents are
flashback_scn=2117284
DUMPFILE=ogg_user.dmp
LOGFILE=ogg_user.log
TABLES= SCOTT.DEPT,SCOTT.EMP
DIRECTORY=DB_DIR
Here flashback_scn is a specific scn to make a consistent
database backup, it can be find by following query
SQL> Select current_scn from v$database;
CURRENT_SCN
-----------
2117284
Transfer the backup from source to target DB
server using below command
scp ogg_user.dmp
192.168.56.104:/home/oracle/
b At Target Database Server
impdp directory=db_dir dumpfile=ogg_user.dmp
logfile=ogg_user.log
Configure Source :-
Add
Trandata
i. Create trandata statement
and execute it on gg prompt
SQL> select ‘add trandata ‘||owner||’.’||object_name||’;’
from dba_objects where owner=’SCOTT’ and object_type=’TABLE’;
‘ADDTRANDATA’||OWNER||’.’||OBJECT_NAME||’;’
