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 (

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.

OS Commands and API for DCM Application Export/Import Function

In large environments with many LPARs need to be able to sync/transfer/update application definitions in DCM across without manual GUI configuration. Need capability to export an application (or multiple) to an XML or name-pair type type file; that possibly can be text manipulated; and import (add or update) on another system DCM. All the GUI changeable application definitions should be exportable to a text file. The text file should be modifiable to remove settings that need not to be changed. Upon import, only the specified settings should be modified or set. Alternative to be able to select settings/option groups to be exported.
Export/Import should be implemented at OS level commands, via GUI actions, and DCM APIs.

Use Case:

Make changes to application definition that need to be propagated out to hundreds of LPARs. Export file needs to be able to be edited to remove settings that may be custom to other local configurations and to not be transferred. Import needs to read the one/many applications in the file and make the indicated changes/additions on the target systems.

    IBM does not intend to provide an additional solution to this request, so it is being closed. Existing APIs can be used to automate "export/import" for DCM Application Definitions.

    Application definition attributes that have been updated on one partition can be replicated to other partitions with the help of a few APIs. Application definition information is retrieved from the primary partition using API QycdRetrieveCertUsageInfo. When using format RCUI0400 of this API, all information that is seen in DCM is retrieved including but not limited to TLS protocols, cipher specifications, supported signature algorithms, list of assigned certificates, the list of trusted Certificate Authorities (CAs) and more.

    Information about the application definition that was retrieved can then be modified by the calling program and used as input for API QsyRegisterAppForCertUse. When using QsyRegisterAppForCertUse on an application definition that already exists on a system, it will update the existing application with the new values specified on the call. The calling program can also assign the needed certificates to the application definitions using API QycdUpdateCertUsage and update the CA trust list with API QycdAddCACertTrust.

    IBM has received the requirement and is evaluating it. IBM will provide a response after evaluation is complete.

    The CAAC has reviewed this requirement and recommends that IBM view this as a “nice to have” low priority feature. This does not seem like a common scenario, and providing edit authority seems to just provide an undocumented way to do an edit.

CAAC has a key role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community, and has therefore reviewed your RFE.

    The CEAC has reviewed this requirement and recommends that IBM view this as a MEDIUM priority requirement that should be addressed.

    The ability to export and import the application definitions is not available, but there is an API which allows you to create or update application definitions.
    The Register Application for Certificate Use API ( allows you modify the TLS Protocols, ciphers, signature algorithms, cache time-out values, and any other attribute that is seen on the DCM panel.

    Specifying the needed modifications within a source file and calling the API to have the update performed will reduce time and effort compared to making the change using the GUI on that many partitions.
