Error description

  • When using IPV4 addresses on a Windows system that supports
    IPV6 addresses, the following MQ command does not display the
    expected value for IPADDR:
    
    DIS LSSTATUS(*)
    An example of the output is:
    AMQ8631: Display listener status details.
    LISTENER(TCP_LISTENER)                  STATUS(RUNNING)
    PID(1234)                               STARTDA(2011-08-05)
    TRPTYPE(TCP)                            CONTROL(QMGR)
    IPADDR(::)                              PORT(1414)
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users who run a Windows operating system which supports IPV6 and
    who have provided an IPV4 value for IPADDR in a listener
    definition.
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    If the Windows operating system supports IPV6 and an IPV4
    address has been given for IPADDR then WebSphere MQ attempts to
    convert the IPADDR IPV4 address to an IPV6 address. On the
    Windows platform this fails and leaves the IPV6 representation
    blank.
    
    When WebSphere MQ then tries to format this address for display,
    the operating system returns "::" which is an IPV6 shorthand for
    a zero address.
    

Problem conclusion

  • The code was changed so that it no longer attempts to convert a
    IPV4 address to an IPV6 address if the Windows operating system
    supports IPV6.  The result is that DIS LSSTATUS(*) now shows the
    address that the listener was defined with.
