The time reported is in milliseconds and that's what is shown over here. There is no effect of this on the database and TBH there isn't much use of this okay message as well as there is no attempt done to actually connect you to the requested service. Thus if there are any issues related to getting connected , you would only come to know about them once you would actually give a connection request.

Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = sgc-ora-fra1)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = STEMEUROSTEMCELL.COM)))
OK (5510 msec)
OK (10 msec)
OK (0 msec)
what could be the reason that shows result like this. Does it effect anything on the database. Please give your valuable answers.
