To determine re-usable ePVT of a MQ CHIN address space

We have been getting alerts for high ePVT utilization for multiple MQ CHIN address spaces regularly. This is because of high number of channel connections/disconnections driven by business requirement ie client scales up multiple connections to meet their volume demand. We have raised multiple cases with IBM for their support(recent case#TS017575758) in this regard but based on latest discussion with Beverly Brown from IBM support, we understand that there is no direct way to determine the re-usable ePVT or actual ePVT available. Since, we react based on the available ePVT, when there is high watermark we tend to recycle task or go for an IPL which is not ideal.

Ask1: Actual available ePVT visibility would help our SRE team when to react.

Ask2: If ALL unused ePVT can be reclaimed which at this point we assume is not happening.

    Message CSQX004I describes how much private storage is currently used by the channel initiator and how much is free.
    When the channel initiator is using more than 75% of available storage it will attempt to release any isn't strictly needed and will output message CSQX068I. Message CSQX004I will then be output to summarise the current storage availability.
    Therefore these two messages can be used to establish how much storage is available.

    In scenarios where the channel initiator is running with lots of active channels it will likely be using a lot of storage. For as long as there is still some available storage then recycling the channel initiator should not be necessary as that disrupts existing running channels.

    From 9.4, the buffers used by client channels are held in 64 bit storage, which are far less constrained than 31 bit storage. We would recommend that you migrate to 9.4 to take advantage of this function.

    We are declining this idea as the messages described above are already available, and 9.4 significantly reduces memory constraints.
