RE: Websphere Development Studio dropping connection

Hi John,

This question was just asked on the WDSCi-L list.
Check this option out:

"CFGTCP
Option #3
TCP keep alive . . . . . . . . . TCPKEEPALV

The default value for TCPKEEPALV on our system was 120 (minutes). I changed it to 5, and so far so good. I just sent an unrelated message to this list and it occurred to me that I did leave RDi alone for a good hour and came back to it without issues."

OK, more details.

You are correct and I apparently did not hit the C hard enough. :) I am running WDSC - IBM Websphere Development Studio Client for iSeries version 7.0.0.

The client iSeries OS is 6.1.
The company iSeries is 6.1 and 7.1 (different LPars of course). There is also an antique in the corner running V5R4M0 that doesn't have a problem either.
I'm not sure about the product release levels and which ones I should look at.

I really think there is a weird network problem here and was hoping I could point them in the right direction. I have hit other problems with then where they are not "blocking" any outbound traffic but I can't VPN into my company without connecting to my hotspot instead of their network.

John,

WDS is the product name for SEU, SDA, RLU, and whatever else exists under that "Websphere Development Studio" banner...

There USED to be an eclipse based client that was labeled as "Websphere Development Studio Client", or WDSC for short... This product has been replaced (several times) by "Rational Developer for POWER systems", commonly referred to as RDi. Current version is 9.1. I assume that when you say WDS, you really mean RDi.

OS and product release levels?

Firewall is still probably the culprit. We maintain an internal "PCI Segment" to rigidly control network access across this "boundary". If your host stores PCI controlled data (Credit Card anything), then it is likely behind another firewall.

Subject: Websphere Development Studio dropping connection

When I use WDS at one of my clients, my session disconnects after an idle period (not sure how long, maybe 30 minutes) and I have to close and restart WDS to get reconnected. When I get reconnected and try to reopen the source member that I had open it tells me the member is already open and gives me an option to kill the old job. It is also worth mentioning that I do not lose my 5250 connection when this happens so it is not a network dropping issue.



When I am connected to my company's iSeries, I can leave WDS idle for hours and I never lose the connection. Is there some kind of timeout on my client's iSeries that is causing the disruption?
