IBM Power Ideas Portal


This portal is to open public enhancement requests against IBM Power Systems products, including IBM i. 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
  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

Allow IBM ACE to support configurable sequential or batch startup of Integration Servers (DataFlowEngine processes) during node startup

In environments hosting a large number of IBM ACE Integration Servers on a single host, all DataFlowEngine processes currently start concurrently when an ACE Node starts. This can cause temporary CPU and memory spikes during server reboot or service startup, even though runtime resource utilization remains low once all servers are running.

We would like IBM ACE to provide a configurable startup policy that allows Integration Servers to be started:

Sequentially (one server at a time), or
In configurable batches (for example, 5 servers at a time)

This would help reduce startup resource contention, improve startup reliability, and minimize situations where some Integration Servers fail to initialize correctly after a reboot.

The default concurrent startup behavior could remain unchanged, while providing administrators with additional options to better manage startup workloads in large ACE deployments.

Business Benefit
Reduces CPU and memory spikes during startup.
Improves reliability of large ACE environments during server reboots.
Reduces operational effort and manual intervention.
Helps customers optimize existing infrastructure without increasing vCPU or memory allocations.
Provides greater flexibility for virtualized and consolidated ACE environments.
