  • 1.  yobsytcpdp failing intermitently to assign tasks to the right job

    Posted Dec 23, 2014 02:34 AM

    Hi all

    we are experiencing since some weeks ago a  strange behavior with yobsytcpdp dispatcher: after some extension of time attending compilations (it is our development iseries server) all client connecting to server starts sending tasks to the wrong job: a user "x" launch a compile job, it starts but assigned to another user "z", ending up compilation with an object owned by programmer "z", and messages redirected to him. Same for any process (running test applications also): messages assigned to some other owner different than the one launching it.

    In such cases, by now, we opted for stopping the dispatcher, and restarting it. This way the problem dissapears, but some time later it returns. It happened at the time we added calls from another system (Linux) other than our usual Windows 7 workstations. By some time we think something in the Linux requests could be the cause, but after stopping this connection, our problem continued.

    Do you have some experience on such problem?

    We are working in a system i v7r1m0, with Plex 6.1.

    Thanks in advance

    Hi,

     

    Recommending to update your yobsytcpdp dispatcher to Plex 7.1: Works fine with Plex 6.1. There were improvements at least to Plex 7.0 yobsytcpdp dispatcher to 'recover' errors which failed with 6.1.

     

    Latest Plex 7.1 yobsytcpdp dispatcher is more stable than older ones.

    Thanks Kari

    since past Monday our development dispatcher works fine, having changed none. I´m waiting for a new fail to gather as much info as possible to pass to CA support. Your solutions seems easy to test, because we can start another dispatcher and switch to it as soon we get such behavior again. Have you experience running Plex 6.1 with dispatcher from 7.1? Is it required to use 7.1 library replacing 6.1 objects?.

    Anyway, we are planning to move to 7.1/7.2 next year.

    Strangely, our production dispatcher works fine with similar setup...

    Thanks again, Kari. I will try it, indeed.

    You can have both 6.1 & 7.1 dispatchers running in a same box. Utilize a different port for 7.1.  Modify ini settings in application /  Plex development environment to match your new port. (Create a duplicate JOBD for Plex 7.1)

     

    We have used Plex 7.1 listener for Plex 6.1 based application & development work successfully.

    ok, Kari. Nice to know you worked using this method. As said, we will make a try starting January.
