Mainframe Performance Topics Podcast Episode 6 "Expect The Unexpected"

(Originally posted 2016-07-11.)

Episode 6 was a complete surprise to us!

Marna had thought I was on vacation a week earlier than I was. To be fair, I expected to be with a customer in Australia that week. But then the workshop got pushed back and so this week came free [1]

So we went “why not?” and so this episode was born.

It is of course largely built around this blog post but we had a couple of other things we want to say.

And I wanted Marna’s take on the topic.

Talking of the other topics, it’s occurred to me the QR Code capability in zEvent 3.0.0 could be a thumpingly good way of setting up subsequent devices with the same Connection URL.

And the audio production gimmick is accidental this time. 🙂

Below are the show notes.

The series is here.

Episode 6 is here.

Episode 6 “Expect The Unexpected” Show Notes

Here are the show notes for Episode 6 “Expect The Unexpected”. Here is the link back to all episodes: Mainframe, Performance, Topics episodes.

The show is called “Expect The Unexpected” for two reasons:

  • We really didn’t expect to be recording an episode in this timeframe.
  • The Performance topic lends itself to such a title.

We had one piece of follow up:

  • IBM zEvent has been updated to 3.0.0 (“The Cat”) on both Android and iOS. It has enhancements in lots of areas. The one we both noticed was the ability to show and scan QR codes for connections.

Mainframe

Our “Mainframe” topic was a discussion on IBM Doc Buddy – available for iOS and Android.

It’s a tool for looking up error messages and is now enhanced with z/OS Unix Reason Codes. It enables retrieving z Systems message documentation and provides the allows you to look up message documentation without Internet connections after downloading desired files.

It’s available for z/OS, as well as other products like CICS, and IMS, and for many releases of those products.

Performance

Our “Performance” topic was about what happens when unexpected work appears on your beloved mainframes. A number of themes were discussed, including:

  • Not knowing mobile workload was appearing – leading to potential loss of savings on Mobile Workload Pricing.
  • When unannounced work arrives, leading to implications for e.g. Security, Performance Management, and Capacity Provisioning.

In reality how you handle this is a governance and culture question, but we want you to think about the problem.

Topics

In our “Topics” section we discussed two items:

  • iTunes – where you can now find our podcast here. We hope some of you find this new way to subscribe easier.
  • Liberated Syndication (or LibSyn for short). This gives us some interesting statistics about our listenership.

Where We’ll Be

Martin is taking a well deserved vacation for July, so there’ll be no new podcast episodes in July. But we promise to return early in the Autumn!

Marna is going to SHARE in Atlanta, August 1–5, and IBM Systems Symposium in Sydney Australia (August 16–17).

  1. When I say free I guess, as always, I should mean “it got filled up with lots of other good stuff” :-). I might blog about some of it when I return from vacation.  ↩
