The SMf99 subtype6 records have two fields called SMF99_Time_at_PDP_Using, and SMF99_Time_at_PDP.


What does PDP stand for (in this context)?
What do those fields tell me?

... and also SMF99_HdLockPromotion _Time_at_PDP etc. Hmmm, new fields for me to learn ...

Thanks, but the first one points to networking stuff (IP diagnosis), and the later two point to the SMF manual which is where I stumbled across those fields. The term PDP is not explained anywhere in that manual.

I'm not 100% sure but that could be "promoted dispatching priority" where
SRM temporarily promotes an address space to a DP of X'FF' while it holds a
local lock.
