connection drop out

[prasad_15]

Hi,

we are facing connection dropouts in our application . Can somebody please tell what are the factors that we should concentrate on to avoid this. This is becoming a major obstacle for the implementation of the application .

Thanks and have a great day!

What type of application and what type of drop out are you experiencing? Are they telnet connections or something else?

Do you get "source quench messages"?

Is the lan card working correctly? i.e. The correct duplex.

# lanadmin -x 0

Are there any logs that show some additional information from the application. Also check the /var/adm/syslog/syslog.log file.

You could set some network tracing, but I think looking at getting some additional information first may help.

Hi,
have a look at the man pages of "nettl", capture the network events, activities and log for a period of time and format the logs using "netfmt".
Have a look at those logs, it should give you a better understanding as where, when they are happening and then nail down to why its happening.

Cheers

This is a oracle 9i web form application . The connection with client session abruptly drops and all the data entry gets lost . the database is running in a superdome and application server is running on a HP UX.

Note any increase in dropped packets or collisions. Issue the following command on any machine on the network, and do so periodically. You're looking for increases.

# netstat -i |grep -i -e collisions -e dropped

Also track dropped packets.

The number of collisions (Coll) divided by the number of output packets (Opkts) is the collision rate. If your collision rate is greater than 10%,
