Error description

  • For applications written in Pascal (e.g. SMTP), when Dist.
    Method=serverWLM is coded, target stacks use BaseWLM instead, as
    seen on VDPT display for given DVIPA port. A dump of the
    distributor will show this:
    
    DistMethod = ServerWLM
    DistActive = BaseWLM
    
    This is caused by have incorrectly assigning value to the
    token that represents the WLM weight of that ASID
    (tcbext_as_stoken) - see EZBTCNET.
    
    This problem happens with SHAREPORT is coded.
    

Local fix

  • Delete SHAREPORT port reference.

    ****************************************************************
    Display of VDPT shows a distribution method of BaseWLM instead
    of ServerWLM when a Pascal application is listening on a port
    with the SHAREPORT option.
    
    The VDPT display can be corrected by removing the SHAREPORT
    option from the PORT statement and recycling the listener.
