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.

This RFE is satisfied by the resource overrides feature provided by PH30590 on CICS TS 5.6
This feature enables a system programmer to tailor the resources for a specific CICS environment, and provides the following advantages:
• You can take a set of CICS definitions from development through to a production environment without change. Any resource attributes can be overridden to support each environment as required.
• In addition, you can use system-specific symbols such as the SYSIDor APPLID to override attribute values dynamically when a resource is installed.
• You can apply standards by ensuring that certain attribute values are always turned on or off, or set to a specific value.

We also would like to see this made available across various RDO resource types and attributes. For LIBRARY DSN's, we have the same issue as others who use LPAR- and or release-specific DFHRPL datasets. Also for FILE DSN's, we currently use an inhouse PLT program and XRSINDI-driven program to do our own symbol susbstitution from a control-card-supplied list of symbols and substitution strings. It would be nice if such a feature could not only reference system symbols, but also those defined via JCL SET statements in the startup proc/JCL.
We also would find this very usefull and it you help us to define various ressources in an easier way in our sysplex!
We would find this useful. In fact almost essential to replace application datasets in DFHRPL which are often defined like this
XXXX.&SYSNAM1..SYSTEST.B.RBP.O.LOADLIB
XXXX.&SYSNAM1..ACCTEST.A.RBP.O.LOADLIB
etc
so that a different dataset is used depending on which lpar the CICS region runs on. This is perhaps a legacy from when DASD was unreliable but the principle of not having a single point of failure that effects more than one lpar is still a reasonable one.
A system symbol could also be used as a way of switching maint levels.
Adding system symbol support to RDO resources (LIBRARY, FILE, etc.) would greatly aid in our use of a multi-runtime file configuration for implementing maintenance to our CICS applications.
This is a candidate for a future release
