Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users who wish to use the DISCINT functionality with a channel
    that has a SHARECONV value greater than 0.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    Non idle clients are incorrectly disconnected with an MQRC 2009
    when a DISCINT timeout is hit on a channel that has both a
    DISCINT value set and has a SHARECONV value of greater than 0 .
    
    e.g. A waiting getter with a WaitInterval of 15 seconds will be
    incorrectly disconnected if the DISCINT value is set to less
    than 15 and SHARECONV is set to greater than 0.
    

Problem conclusion

  • Processing for SVRCONN channels has been updated to correct the
    logic to ensure the channel does not timeout unexpectedly in
    this case.
