    We have assessed this requirement. We have no current plans for this to be implemented and so this requirement is being declined at this point. The introduction of SOTUNING in CICS V5.3 provides some support. If SOTUNING is active (which it is by default) then persistent connections are only actually persistent for 1000 requests.

    The requirement will be kept in the RFE system and might be reassessed in the future. You also have an opportunity to resubmit in twelve months time if you wish it to be reconsidered then.

    Hi Mike,
    I think we may have addressed this with the introduction of SOTUNING in CICS V5.3. If SOTUNING is active (which it is by default) then persistent connections are only actually persistent for 1000 requests. After the 1000th request they are closed and so have to reconnect, which for your scenario would allow them to be balanced over any new port sharing regions just started up. Does this sound like it addresses this issue, is 1000 requests a low enough number to provide the function you need?
    Regards, Alison
