Home -> Community -> Mailing Lists -> Oracle-L -> Re: interesting tnsping times...
Hi, John,
I wonder if you can take a look at what network packets are sent between this machine and the server. For NT, use the free windump (http://netgroup-serv.polito.it/windump/). At one time I had too much time to burn and I studied tnsping at the TCP level. There're a few PUSH actions after the initial 3-way handshake. Do this on your machine and then on other machines. Let us know if you find anything unusual.

Hey folks, got an interesting problem here... maybe I'm missing something so I need some help:
I have an NT machine that is acting as our reports server/OAS for a web reporting solution. This has performed terribly for us in many environments, but that is beside the point.
Anyway, I can ping our server with excellent response times (<10 msec) from this NT machine. The problem is when I tnsping80 the instance, I get HORRIBLE times ( 5100 - 5300 msec). From any other client, I get response times from tnsping80 between 600-760 msec. It is just this one machine that is having the "problem". The tnsnames.ora files on this NT machine and the clients are the same.
