IBM Sterling Ideas

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:

Post your ideas

IBM is transforming its request for enhancement (RFE) process. The purpose of the transformation is to provide a more consistent experience for you to submit requests and to enable IBM product owners to respond to your requests more quickly. For more information click here.

Start by posting ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,
1. Post an idea
2. Upvote ideas that matter most to you
3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The offering manager team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notifications on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

External Purge Memory settings are inconsistent between Windows and Linux/Unix and changing the memory settings is complicated

It is very confusing that Xmx for Ext Purge on Windows defaults to 512m no matter what the Noapp is tuned for. However on linux/Unix the -Xmx for External Purge is pulled from whatever the Noapp is set for. This is very inconsistent and can cause issues on Linux/Unix with Native Out of Memory when customers increase the Noapp memory to a larger number since both the Noapp and External Purge are using the same Xmx values.

Here is a link which discusses how to modify the -Xmx for External Purge on Linux/Unix:
https://www.ibm.com/docs/en/b2b-integrator/6.1.0?topic=ep-changing-xmx-other-memory-settings-external-purge-unix-linux

As you can see from these instructions it is very difficult to procedure to follow.

Ideally External Purge should have something more straight forward to changing the memory values. Would it be possible just to have the ability to add the memory parameters to the archivethread.properties_hpp_ext properties file or customer_overrides.properties?

External Purge memory settings should be consistent and easily modifiable.
