To confirm that the data is replicated the following query can be run on both the source and the target database.

1. Connect to the source database.

No Format
sqlplus oe/oe@ttorcl_src

Run the query.

No Format
SQL> select to_char(sum(order_total),'$999,999,999,999.00') "Total Orders" from orders;
 
Total Orders
--------------------
$7,317,074,993.00

2. Connect to the target database.

No Format
sqlplus oe/oe@ttorcl_trg

Run the query.

No Format
SQL> select to_char(sum(order_total),'$999,999,999,999.00') "Total Orders" from orders;
 
Total Orders
--------------------
$7,317,074,993.00

...

 On the source server, as oracle, in the $HOME/replicate directory, execute the record_count.bash script to check the number of rows in each table and the sum total of all orders in both the source and target databases.

No Format
./record_count.bash
 
Note

This queries should give the approximately the same number on the source and target database when the replication is < 100%.

Run the queries several times to see that the numbers are updating on both the source and target database. 

If the replication is at 100% then the numbers will should be the same.
