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.
