Import new rows to the existing table (urgent)

Question

Hello everyone,
i have two databases in different locations. but in the initial stage, both are same.
if i add rows or update rows in database 1, i want to export the rows updated or added newly from database 1 and import to database 2 without any modification in database2 (i mean only the modified rows and new rows only to be imported to database2)
for example;
in initial stage
database 1-
table 1(5 rows)
table 2( 6 rows)
table 3 (1 row)
database 2-
table 1(5 rows)
table 2( 6 rows)
table 3 (1 row)
later stage
database 1-
table 1(7 rows)
table 2( 9 rows)
table 3 (1 row)
i need to update the below database 2 with 2 rows in table 1 and 3 rows in table 2. and it should not affect the table 3.
database 2-
table 1(5 rows)
table 2( 6 rows)
table 3 (1 row)
i need a solution for this. if anyone know the solution plz post the reply.

Answer 1

also expdp and impdp commands will work on 10g only i think so. but we are using 9i.Since you're using 9i, use Query option from Export(exp). Below notes would help.
