Hello! I did a search for this question, but did not see an answer. So, I apologize in advance if it has been answered already and I did not find it. We have an exit into dynamic allocation. When I do an edit of a PS file in ispf 3.4, I see the allocation as disp=shr first then a follow on allocation of disp=old for the same data set. Is this normal? How does this affect enq processing?
Thanks in advance for any knowledge of how this processing works.
Thank you for the reply. We have an exit in dynamic allocation and I can see two distinct different calls (very close together) for this ps dataset. The first has a text unit of disp=shr and the second has disp=old. I discussed this with a developer in allocation who saw the same behavior. There must be a reason for this, maybe to see if it is actually even possible to edit the file at this time.
