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.
Specific links you will want to bookmark for future use
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.
IBM Unified Ideas Portal (https://ideas.ibm.com) - Use this site to view all of your ideas, create new ideas for any IBM product, or search for ideas across all of IBM.
ideasibm@us.ibm.com - Use this email to suggest enhancements to the Ideas process or request help from IBM for submitting your Ideas.
Whilst this requirement is valid, based on our current plans and priorities, it is not likely that this could be implemented in the next 12 months, or in the next CICS TS release. Correspondingly this requirement 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 - Transaction Processing
Product - CICS Transaction Server
For recording keeping, the previous attributes were:
Brand - WebSphere
Product family - Transaction Processing
Product - CICS Transaction Server

Hi John,
Thanks a lot for taking care of this requirement.
1. We are using HTTP protocol (mostly inbound). We are not using the IPADDRESS field because the Network people (and neither we) don't like native IP addresses to be coded in the system. The IPADDRESS field is nice but it would be much smarter if the IPD Stack can be addressed by it's name like can be done in IMS (HOSTNAME=tcpip_jobname). This make us independent from Network changes.
We have up to five TCPIPServices defined in a single CICS region.
2. We didn't evaluate the BPXTCAFF utility. To tell you the truth we (the CICS group) were not aware of this utility. This utility does not provide the flexibilty we like to have. A restart of CICS is required to apply changes (a big problem in a 24/7 environment) while a TCPIPService can be installed dynamically.
To help clarify this requirement can you provide details to the following questions:
1. Why using the IPAddress field on the TCPIPSERVICE does not address the requirement to use a specific stack (in particular we need to know what CICS protocol is being used (IPIC, HTTP, ECI), how many of each TCPIPServices are in use per region, and if there are inbound and or outbound sockets used.
2. If BPXTCAFF utility, which will provide IP stack affinity for a given job, has been evaluated.
