Error description

  • VIPADISTRIBUTE with dynamic ports .  When the DVIPA (current
    distributor) moves from one LPAR to another, all listeners might
    not be registered with the new owner of the DVIPA.  Netstat VDPT
    will not show the listeners.

Local fix

  • quiescing and resuming the ports individually on the target
    will workaround the problem

    ****************************************************************
    A sysplex distributor is configured with at least two DVIPAs
    which are distributed, DVIPA1 and DVIPA2. DVIPA1 is defined
    with ports to be distributed on the VIPADISTRIBUTE statement.
    DVIPA2 does not define any ports, so sysplex distributor will
    dynamically be updated when a server binds to DVIPA2. A port
    is defined statically on DVIPA1 and an application is
    bound to DVIPA2 on the same port.  When a new owner takes
    over the DVIPA, listeners on other ports on DVIPA2 are not
    dynamically updated to the distributor.

Problem conclusion

  • TCPIP is updated to update the distributor for all sockets
    listening on a DVIPA with dynamic port assignment.
