We have two computers at our production site and one at our DR site. All computers run z/OS. One system runs a payroll application, and the other runs a provident Fund Application. Both systems provide services to external customers. The computers are connected to an IBM DS9810F storage system and an IBM TS7770 virtual tape system.
- Massive I/O
- Support many users concurrently
- Very little downtime required.
Cons
- It's hard finding new people with the required knowledge.
- It seems expensive.
- Very little down time
- Massive i/o
- We've always used z/OS for these applications. Every attempt to even plan using a different system failed very early in the initial stages for various reasons.
We recenetly attepted to evaluate moving an application to the MicroFocus environment.
The initial assessment failed because of cost.

- Run monthly payroll calculations

- Importunely, the powers that be want to move us of z/OS
No

When we started with IBM Z, there weren't any other options.
Along the way, other options have become available, but none were good enough.

- Implemented in-house
Yes
Most the applications we run are 40 years old and have gone the many development stages.
- None that I know
- Online Training
- In-Person Training
Work with an IBM business partner who is an expert.
Some - we have done small customizations to the interface
IT very easy, if you know how, to add options to ISPF, which is the main interface you use in z/OS.
Some - we have added small pieces of custom code
We have a huge ISPF application that helps non-professionals do things.
no
THere is other option
No
A while back I was in the process of putting a new computer into production.
I realized the an important function (STP - the function that lets z/OS get the accurate time from the network) wasn't working.
After trying to solve the problem on my own, I opened a Severity 1 issue.
I was online with support teams from around the world until they found a way to bypass the problem so I put the computer into production.

- The builtin editor is great
- Monitoring system activity is easy with SDSF
- There a products to do anything you would need. Usually more than one option for each task.
- Configuring a new system.
Yes
There a many options. There is HMC Mobile that lets you control the HMC from your phone.
There are also other options.

- Many other systems running Windows or *nix
z/OS connects to the network using TCP/IP.
It can be a web server, a database server, an ftp server, or almost any other kind of server.
It can publish it's features as web services, or as other types of services.

- Nothing new
- File import/export
- API (e.g. SOAP or REST)
Know what options available.
If there is more than one option, evaluate more than one.

I'm not involved with that part.
You usually go through a business partner.
Since we're in a small market, there is only one.

Our most recent upgrade was a new computer. Once we dod all of the configurations, moving it int production was a simple matter of shutting down the old system, connecting the cables, and starting the new computer.
- A new system with some new functions
- Lower software costs.
- More of the same
