IBM Z Software
This portal is to open public enhancement requests against IBM Z Software products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).
Shape the future of IBM!
We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:
Search existing ideas
Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,
Post your ideas
Post an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.

Development looked into the CEDF code to doublecheck if the external behaviour is consistent with what is expected.
The clearing up of the shared storage is being performed in a CEDF routine called purgeci (purge control information). They followed the execution of CEDF and here's what they found :-
1. If PF3 is hit, purgeci is invoked to clear shared storage, CEDF immediately exits and the program runs to completion
2. If the program is run to completion and YES, the default response, is the response to the 'continue CEDF' question, the shared storage is NOT cleared. This is the expected behaviour.
3. If the response to the 'continue CEDF' question is NO, purgeci is invoked so the obtained shared storage is cleared.
Calvin, can you please explain if the customer is experiencing something different to the cases I outlined above? How does he know shared storage is being leaked?

Q1:What is causing the online user to ungracefully terminate from CEDF?A1:When the CEDX/CEDF is running, customer might use PF3 to exit the CEDX/CEDF, but the 'continue?' option was not displayed. So the default value 'Yes' will make the storage stay at CDSA and will not be freemained .
Q2:How often does it occur?
A2:Every two or three days.
Q3:We are looking at removing the need for CEDF to use 24bit below the line storage in the future, which would mean this would not cause problems for the heavily constrained CDSA and it would then be in ECDSA. Would that cause less of a problem ?
A3:That will cause less of problem, but that will not prevent the problem(only less occurring),
Because the default value of that option is "Yes", and at anytime customer didn't retype the option to ''No", the storage will not be freemained. So if there is a parm or option to control this CEDF option(customer could easily change 'Yes' to 'No'), it will be better to prevent this problem.
