IMS on z/OS provides speedy transactions and high availability
Ericsson (formerly Telcordia) provides IMS DB/TM-based inventory systems for very large phone companies. Although primarily IMS-based, we use IMS Connect, DB2, and MQ as well. We make extensive use of MQ and IMS Connect to allow access to our systems for users beyond just the 3270 world. We transformed all our 3270 green screens with our Xj (JAVA eXtensions) product so our users have the advantage of a modern interface. MQ is used to interface with both our other systems that run on other platforms (UNIX, LINUX, etc) as well as an interface to other phone company systems not written by Ericsson.
- I/O is very fast in IMS and outside of IMS as well
- CPU speeds are as fast as any other platform
- User interfaces remain fairly constant (TSO, IMS, DB2, MQ, etc)
- Support is good, but more examples, especially of non-Z/os things like JAVA, would be helpful
- Security is becoming so prevalent it's cumbersome at times.
- Less emphasis on exits coded in BAL/ASM and more parmlib/proclib members would be helpful

IBM Z and Storage Technology
IBM Z Mainframes are used to support z/OS and z/VM operating systems on a minute to minute basis.
These operating systems support critical applications and infrastructure to support front line business needs such as Claims Processing, Web Applications, DB2, CICS Transactions, and IMS Databases.
These operating systems support critical applications and infrastructure to support front line business needs such as Claims Processing, Web Applications, DB2, CICS Transactions, and IMS Databases.
- IBM Z Technology supports the critical Infrastructure needed for reliable Data Centers to support business needs.
- IBM Z Mainframe Technology is used worldwide for the amount of MIPS (Millions of Instructions Per Second) and processing power/data handled by this equipment.
- IBM Z Storage is Infrastructure that supports large amounts of critical data. (Direct Access Storage Devices, Virtual Tape Subsystems, and Physical back-end Tape)
- More access methods from a Management GUI Interface to help support on-site IBM SSR's perform job duties. IBM SSR's log into one or more IBM TSSC's (Management Interface for IBM personnel) to support Support Infrastructure needs such as: enabling AOS, offline of a back-end TS11** tape drive or Downloading VTD Exec's which could be critical fixes released from support seen in the field.
- More detailed/extensive lab testing before Ficon Host Adapters or ETH cards are released to new equipment sold in the field. We experienced multiple disruptive "Ficon Panics" within the recently purchased TS7760 Technology that had 16Gb Ficon cards behind a z14 mainframe with 16Gb Ficon cards. This turned out to be the following: shortage of data descriptors, block sizing, related to EEH or CAD code and we had an IBM TS7700 Architect come on-site and explain that a fix was made in the 8Gb Ficon cards that wasn't brought over into the 16GB Ficon cards. We've had to remove twenty 16Gb Ficon cards from seven TS7760's in our environment and replace with 8Gb Ficon cards until IBM Development release's VTD Exec's and CMVC fixes before another implementation plan.

Mike Barone Review
IBM Z is being used as a test environment. Our TEC center gets equipment from manufacturers to show clients how the technology works. It is strictly for a non-production environment, as detailed by IBM. We are not able to do our own production work on the system, just use it to show customers how it works.

- Interface.
- Ease of use.
IBM Z Series Enterprise Servers provide the power and reliability needed for the largest organizations to drive large numbers of transactions and gain insight from their data. If you are looking for a platform with high availability that can scale on demand and deliver performance with optimal security, these things are second nature to mainframe computer systems and applications.
The mainframes I have worked on are typically used across the whole organization to address the enterprise business needs of the organization. They run multiple applications for multiple business lines.

- Security is a specific strength of the Z platform. The IBM z14 provides Pervasive Encryption, making the platform one of the most secure hardware offerings available. Specialized cryptographic hardware is utilized to encrypt data and protect encryption keys, enabled through integration with a tamper-responding cryptographic HSM. The IBM z14 pervasively protects all application and database data, without interrupting business applications and operations, all the time, at any scale. True end-to-end data protection is provided for all in-flight network data and APIs. Imagine being able to protect all your data and applications without requiring IT or programmer action. With the z14 this becomes reality instead of imagination.
- IBM offers flexible pricing options to make it easier for customers to affordably adopt and utilize the Z enterprise servers for any type of workload that needs to be run. For example, with Container Pricing, customers can identify workload to containers and pay for them independently of any other workload at a reduced price. Container Pricing is an important breakthrough for mainframe customers because it offers competitive economics versus alternative platforms such as public clouds and on-premises x86 servers.
- The IBM z14 delivers high-end processing power and enhanced I/O capabilities. The latest model, the z14, offers increases in the performance of the individual PUs (processor units), increases in the number of PUs per system, a redesigned system cache, and an increase in the amount of memory possible.
- The system is capable of running more than 12 billion encrypted transactions per day on a single system. And the IBM z14 delivers industry leading scale to meet the needs of modern connected workloads. It can run a million Docker containers on single platform.
- The mainframe and z/OS have a long history of providing critical business value with transaction processing systems like CICS and IMS. And the transactions processed by these systems are often backed by DB2 and IMS databases. The applications and databases hosted on mainframe systems provide a rich tapestry of useful information that mobile users want to access.
- And mobile devices can connect to the System z platform consistently and effectively. With z/OS Connect the mainframe can use a single interface on z/OS that accepts standard mobile protocols and formats that can interact with multiple systems on the mainframe.
- The Z platform provides a superior platform for analytics & machine learning for continuous intelligence across the enterprise. The Machine Learning on Z platform, delivered in 2017, offers an agile machine learning solution that enables customers to convert enterprise data into opportunity. With machine learning on an IBM z14 you can optimize your decision processes by quickly training, deploying and continuously monitoring a high volume of high quality predictive behavioral models. The IBM z14 can also rapidly analyze large volumes of data with consistent response times by exploiting the additional memory and faster processors of the z14.
- Modern development techniqes and languages can be used, in addition to legacy systems. And Linux can be run on enterprise Z servers just as easily as z/OS.
- And the platform excels at traditional, transactional workloads, both online and in batch, using database systems, flat files, or VSAM.
- IBM needs to add more focus on simplifying mainframe usage and management.
- Most modern programmers interface with the Z using an IDE. However, performing many tasks, such as cataloging a data set or checking on a job status, can require switching to the ISPF interface. Users want to interface with a GUI, not a function-key, menu and character-based interface like ISPF. Anything that can simplify and modernize interfacing with the mainframe should be a high priority for IBM.
- The IBM Z platform is one of the most instrumented computing platforms in the world, so there are a lot of metrics that could be automatically analyzed and used to improve the performance and management of the mainframe environment.
