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).
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:
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 an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.
Welcome to the IBM Ideas Portal (https://www.ibm.com/ideas) - Use this site to find out additional information and details about the IBM Ideas process and statuses.

HourGlass changes the local time for selective applications that take part in a time journey. The HourGlass ACES table contains the jobnames of jobs that are to run with an altered time and is in ECSA storage.
When performing a dynamic ACES replacement ("refresh") there is a hard-coded delay value in HourGlass code to allow running TCB's currently processing a TIME call to finish their TIME call within this delay time before the old ACES storage is released. This delay ("short delay" in the APAR text) was introduced by HourGlass APAR PM47071.
However sometimes a short delay is not enough for jobs that might have been swapped out during their TIME call. If this happens, the affected job or STC suffers from an abend0C4, causing HourGlass recovery code to stop HourGlass processing on the whole system, which leads to jobs taking part in time journeys to run with inconsistent time values.
This poblem is addressed by the current RFE.
The same problem even combined with a potential common storage overlay can arise when stopping HourGlass and freeing ECSA strorage. A later swapped-in TIME caller that had been processing HourGlass code can try to store data in this possibly already resused piece of ECSA storage. A PMR for this aspect can still be opened.
So we suggest to use the same or a different customizable delay value for refreshing the ACES and for stopping HourGlass. The HourGlass code should delay freeing its ECSA storage by the amount of time specified in the parameter.

Please retest with the latest level of HourGlass. Based on our current plans and priorities it is not likely that this will be implemented in the next 12 months and so it is being declined at this point. The requirement will be kept in the RFE system and might be reassessed in the future. You also have an opportunity to resubmit in twelve months time if you wish it to be reconsidered then.
Due to processing by IBM, this request was reassigned to have the following updated attributes:
Brand - Servers and Systems Software
Product family - Enterprise Tooling
Product - IBM HourGlass
For recording keeping, the previous attributes were:
Brand - WebSphere
Product family - Enterprise Tooling
Product - IBM HourGlass
