tnsping takes 3010 msec

Dear Gurus,

What should I check if I found that when tnsping database machine it took 3010 msec then I tried to login using sqlplus scott/tiger@TEST29 I have to wait for 1 sec to logon.

For your information, I use Services as below on my tnsnames.ora in application machines.

TEST29=(description= (load_balance=off ) (failover=on) (address= (protocol=tcp) (host=testdb15v) (port=1521 ))(address= (protocol=tcp) (host=testdb16v) (port=1521 )) (connect_data= (service_name=TEST29_SRV ) (failover_mode= (type=select) (method=basic) (delay=3)(retries=10))))

before this problem happened, machine on testdb15v was hung, I can't access the database TEST29, then I relocate the services from TEST29A to TEST29B. but when I tried logon to database it took a while to logon.

Howdy, Stranger!
