Solaris Network Connection

Hi,

Recently we faced awkward situation where we cannot connect to Oracle DB that hosted in Solaris server intermittently and it timeout eventually. The server seems fine. We can putty to server like normal but when try do prstat, it takes time and come out Please Wait.. for a while. When we go and check the server log there was an error say "accept:Software caused connection abort, last message repeated 1 time, getpeername: transport endpoint is not connected".

I also got check the tcp listendrop value using "netstat -sP tcp | grep ListenDrop" and the output as below;

tcpListenDrop = 61080 tcpListenDropQ0 = 0.

Can someone advised whether there should any network contention and how to further check on it. I also will appreciate whether oracle listener able to handle concurrent connection

Testing physical network connection

How do you test the physical network connection of an interface in solaris.

But is there any better way to see if you have good layer 2 connectivity? (1 Reply)

tcp-env(1)                                                    General Commands Manual                                                   tcp-env(1)

NAME
tcp-env - set up TCP-related environment variables SYNOPSIS
tcp-env [ -rR ] [ -ttimeout ] program [ arg ... ] DESCRIPTION
The input for tcp-env must be a TCP connection. tcp-env finds out information about that connection, puts the information into several environment variables as described in tcp-environ(5), and runs program with the given arguments. Usually tcp-env is run from inetd. It might instead be run from another server that already sets up the right environment variables; if PROTO is set to TCP when tcp-env is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check whether the input is a TCP connection. OPTIONS
-r (Default.) Attempt to obtain TCPREMOTEINFO from the remote host. -R Do not attempt to obtain TCPREMOTEINFO from the remote host. -ttimeout Give up on the TCPREMOTEINFO connection attempt after timeout seconds. Default: 30. SEE ALSO
tcp-environ(5), inetd(8) tcp-env(1)
