How to check network latency in oracle R12.1.3

1. Navigate System Administrator Responsibility.
2. Navigate to Application
     Click on Network Test.

3. Click the ‘Clear Old Test Data’ button to purge previous test results from the database.

4. Specify the number of Trials and the Iterations for each trial for both the latency and bandwidth blocks. The default settings for both are 5 trials of 100 iterations each.

5. Select the Run Test button to perform the test.

Latency test:- 
It examines the time taken for a single packet to make a round trip from the client side application to the server.

 Bandwidth test:-
It examines the data rate to see how many bytes per second the network can transfer from the server to the client.

Note :- Oracle Recommends Network latency should be low and bandwidth should be high.
