Re: [WDSCI-L] Active jobs timing out

[Don Yantzi <yantzi@xxxxxxxxxx>]

Mark,

The Toolbox's AS400 class lets you set options for the socket it uses to
connect to the OS400 host servers:

public void setSocketProperties(SocketProperties socketProperties)

This includes a keepalive parameter and timeout parameter.  We don't
currently set either of these in 5.1.2 but are looking into this.  I have
had others report similar timeouts with the RSE but have never been able to
figure out which OS/400 setting controls the timeout value in order to
reproduce the problem and therefore know if this would solve the problem.

If anyone knows this value please let me know so we can fix the problem
[and test the fix!]

Thanks.

Just a few comments, perhaps they can help or clarify.

The TurnOver jobs and the RSE jobs are not related to each other.  With
the exception that I think we are both using JT400 as the middleware for
the communications.  I suspect that the RSE jobs just reconnect silently
when the connection is dropped.  As you indicated, that is also what we
essentially plan on doing.  For us, however, it is a little more
complicated because our jobs are interacting with the database and will
lose their "state" when the connection drops.  RSE jobs are mostly
stateless since they are just driving OS/400 API's.

It would be great if an IBMer on the list new what controls this behavior,
but perhaps we would have better luck moving this to the JT400 forums
since the issue is really in the middleware.

If you run CFGTCP option 3, what is your value for TCP keep alive?  Mine
is 120 minutes, the default.  Not sure if that is even a factor though.
