It's not necessary, no, but you are going to create more trouble for yourself than you need. - Since the user ID is provided by IBM, you will have to do a PPF override so that SERVICE and PUT2PROD know what you've done. - Create :Type.SERVER entries in SYSTEM DTCPARMS for all servers and specify the :Stack. tag as appropriate. (Warning: Do not change IBM DTCPARMS and do not perform a mass copy of IBM DTCPARMS to SYSTEM DTCPARMS.) - Change TCPIP DATA to include the TCPIPUSERID statement to point to your stack You may want to leave TCPIP in the directory (NOLOG) in order to provide indirect minidisk links to the 198, 591, and 592 just in case someone says LINK TCPIP instead of LINK TCPMAINT. The maxim that you don't change or delete what IBM provides, but only add to it, is a good one. While PPF overrides work well for service, there is no generally accessible system registry (e.g. some form of system environment variables) to let the rest of the system know what it is you've done. My recommendation: Create all the stacks you want, but leave TCPIP & Co. alone. Use the suite as your "master" TCP/IP instance, even if you don't bring them up.
