RE:Share Your Mainframe Questions
I would like to know what are considered vital roles within an organization, and the other roles that will be combined and/or eliminated. For example is storage and networking more vital than OS support? Is the DB2 support valued or treated different than CICS support?

Is there industry training not directly related to mainframe or z/OS that are defacto for people to have? Everyone getting "ITIL" training seems to be gaining relevance at our shop, are there others that are similar?

Any predictions would be ideal for us zNextGeners creating training paths and supporting critial components in years to come.

Are clients ready to move on to cloud on Z systems as they consider data security factor?

RE:Share Your Mainframe Questions
IBM Mainframe - backbone for many organizations for last 5 decades. Which is perceived as premium tag product with higher Total Cost of Ownership (TCO) by many IT decision makers. With advancement in commodity hardware capability, orgnizations make it as their architecture choice. Of course, the type of workloads play a major role in decision making, but I would like to hear from IBM Experts on how to make it more attractive choice in terms of cost (both OpEx and CapEx), etc., and roadmap to make it 'evergreen' from its 'legacy' identity.

RE:Share Your Mainframe Questions
If someone says that the total cost of ownership (TCO) of System z is greater than another platform, here are some of the questions that you should ask:
1. How expensive is down time? How expensive is the technician to detect the failure, restart the application or machine and possibly do diagnosis so it does not happen again? The mainframe requires fewer people to maintain than other platforms.
2. How expensive is downtime for lost productivity and lost reputation for the direct and indirect users? If you were considering opening an account with a certain bank and a friend told you that last year he saw an ATM for that bank that was down, will that make you nervous about that bank? (Of course there could be a local electrical failure.) Would you suspect that that bank might not be reliable enough? The bank might not get you as a customer. I heard that a large fraction of the world's ATM networks include System z for reliability and security. The same applies to most companies on Wall Street. The reason that they continue paying for the mainframe is not because they are stuck. It is because of the reliability and security.
3. Are you counting electrical and floor space costs? These small costs add up to a lot. Are some of the costs hidden in other department budgets? Mainframes use much less power and use much less floor space.

RE:Share Your Mainframe Questions
I have been asked to contact someone who works in a large business(such as a Financial Institution/bank, corporate business, telecommunications company, Airlines etc.) working with mainframes could answer these basic questions:

1.List a combination of at least 10 (ten) transactions, routine or ad-hoc tasks and working with applications of what your business/company’s typical workload includes.(very basic things)
2. Write how these tasks are addressed in what methods/ways such as utilities to manage/manipulate data sets, using JCL, using CLIST and REXX etc.
Also why this methods suits and why this method is best suited in terms of response time, speed, ease of use etc.

Can we expect to have System z mobile applications more like the Android, Windows and iOS Mobile apps as Mobile continues to grow in this smarter planet

RE:Share Your Mainframe Questions
I am trying to set an IP on a z/VM LPAR based on cpuid. Is it possible to have a conditional statement in the PROFILE TCPIP config file on z/VM? Or, is there a better way to change the IP?

RE:Share Your Mainframe Questions
Via Alan Altmark, Senior Managing z/VM and Linux Consultant, Lab Services z Systems Delivery Practice, IBM:

Regarding z/VM, yes, it can be done.

The search order for the TCP/IP profile is:
1. <userid> TCPIP (e.g. TCPIP TCPIP)
2. <nodeid> TCPIP (the node you see from the IDENTIFY command)
3. PROFILE TCPIP.

The output from IDENTIFY is affect by CPU id and the SYSTEM NETID file on the 190 disk.


The broader z/VM user community provides quality peer support though the IBMVM mailing list. Please see the site for more information on IBMVM and other z/VM-related communities.
