Hi, Jim --

I think the best thing would be to get a packet trace from both sides and
you can then see exactly what's going on over the network between WAS AIX
and the 400.

HTH,
Gary

Subject: Fw: Java Remote Command Failure

Hi All,

Our QA department is implementing new remote commands initiated from a
WebSphere (AIX) Application Server and they are reporting that 20%-30% of
the remote command connections are failing with the response code:


<ResponseInfo code="6003" description="Connection Exception"
message="Established connection failed to
component:AS400_CMD:216.58.195.132" source="AS400_CMD"/>


I asked for a java log showing the error and received the following:

"2016-05-02 00:14:35.527 [ERROR] [WebContainer : 192]

looking at the classes in in the java logs, it appears that WAS makes a new
connection request from the connection pool but immediately the
ConnectionDroppedException class is invoked and then the iSeries cleans up
the disconnected connection from the connection pool.


I have an open PMR with IBM on both sides but we are finding this difficult
to troubleshoot. Can anyone give any advice for gathering more detailed
insight into digging into this error?
