Moved 8 years ago to include Oracle on Linux on System z
z/OS Oracle de-support
Small technical community and growing

4. Current status of zSeries SIG Group
2008 and 2009 yearly conference attendees were mostly Linux
Oracle on Linux is more streamlined than Oracle on z/OS
In 2010 joined IOUG as a SIG
zSeries SIG sessions held as part of Collaborate
IOUG has been very helpful

6. What is Linux on System z?
It is not your parents mainframe anymore!

7. What is Linux on System z?
A native System z operating environment
Pure Linux, an ASCII environment
Exploits IBM System z hardware, including IEEE floating point
Linux for System z – 32 (31) -bit/64-bit
Not a unique version of Linux or other operating system
Developed and supported by the Open Source Community
Distributed by Novell SuSE, RedHat, and Others
Not a replacement for other IBM System z operating systems (z/OS formally MVS/OS/390)
Can be run Virtual under z/VM or in its own LPAR
Hardware provides a pool of virtual capacity
Only fully supported Oracle environment in a VM aside from Oracle’s VM

MTF measured in decades
RAS features built into hardware
Scalability
Both Physical and Logical
Non-disruptive capacity upgrade on demand
Designed to support mixed work loads
Complete workload isolation
High speed inter-server connectivity
High Internal Bandwidth, sophisticated cache nest
Virtualization

10. What System z Hardware Brings to Linux (cont’d):
Hipersockets

Network stays inside the box - secure
Integrated Facility for Linux (IFL) CPU
Full Processing Speed, not clocked down
IFLs upgrade as hardware is upgraded: z9>z10: 50% performance increase
Processor-based software costs

11. Customer Trends From a perspective of the z Series SIG group
Trend is to move to Linux
Oracle strategic direction is Linux
Oracle and IBM are supporting Oracle products on Linux on z
Long list of 3’rd party vendor now support Linux on System z
Steady yearly growth usage of Oracle on Linux on z
Steady growth of Oracle solutions available on Linux on z

12. Top ten reasons for running Oracle on IBM System z
The Mainframe has been the platform for mission critical
applications for years
Reasons may vary why companies choose to run on the mainframe
Objective of this session is to list some common reasons
You can see if these fit your situation

13. Top ten reasons for running Oracle on IBM System z
Excellent virtualization capabilities of IBM System z,
highest resources use efficiency/utilization, mixed workloads
Ability to exploit existing disaster recovery plans
Lowest security breach risks/costs via most secure design, encryption, etc
High availability features provided by IBM System z
Lowest power consumption, cooling, and data center floor space
Ease of interfacing with traditional data
Increased performance and scalability capabilities of z10
Specialty engines available on IBM System z
End to end solution for dynamic infrastructure data center
Lowest total cost of ownership, total cost per user, and total cost
per transaction

14. Details on using the VM Operating System
The solid virtualization capabilities of z/VM and System z are a key reason
Mature technology
VM/370, introduced in 1972, enhanced and significantly expanded for Linux in recent years.
For ORACLE SOFTWARE - Only fully supported Oracle environment in a VM aside from Oracle’s VM

15. Details on Reason - VM (cont’d)
Software Hypervisor integrated in hardware
Sharing of CPU, memory, and I/O resources
Virtual network – virtual switches and routers
Virtual I/O (mini-disks, virtual cache, and so on)
Virtual appliances (SNA/NCP, and so on)

16. Details on Reason - VM (cont’d)
Easy management
Fast provisioning of preinstalled and configured Linux images. This can be accomplished in minutes instead of days or weeks.
No additional space, electric connections, or network cables.

17. Details – Consolidation Benefits
Consolidate workloads – Green Feature
Use less power (electric)
Distributed servers often run at average utilization levels in the range of 5% to
20%.
Run multiple images on fewer processors
Achieve utilization levels of 85 or 90 % or more

18. Details on Reason - Security
Integrated cryptographic accelerator
Advanced Encryption Standard (AES) 192 and 256
Stronger hash algorithm with Secure Hash Algorithm (SHA- 512)
Tamper-resistant Crypto Express2 feature
Supports high levels of security for demanding applications
Fully programmable and configurable
Highly scalable performance for SSL transactions
Trusted Key Entry (TKE) 5.2 with optional Smart Card reader

19. Details on Reason - Security
IBM LPARs have been certified to the security level of Evaluation Assurance Level 5 (EAL5)
z/VM has achieved the EAL 4+ level of certification

20. Details – Mainframe Cost Reduction with Specialty Engines on IBM System Z
Cost savings are significant based on the Linux Specialty Engine:
IFL processors for Linux are additional engines dedicated to Linux workloads:
Support z/VM and Linux on System z
IFL processors run at “full speed”
• z9 EC, z9 BC, z10 EC, z10 BC, z9 EC, z9 BC, z800, z890
Traditional IBM and Independent Software Vendor (ISV) mainframe software charges are unaffected.
Linux and z/VM charged only against the IFLs.

21. Reasons the data center is starting to migrate to Linux on System z
Floor Space
Use existing System z Hardware
No need to stand up new Hardware or Server (s) for a new project
Security
Ease of network attachment (Virtual IP Addresses)
Ease of Oracle Home Cloning/Same OS
Ease of standardizing Linux Releases
CLOUD Computing - Customers of my customer’s data center pay for what they use
SUSE 10 - Solid operating system under VM
RED HAT Available on Linux on System z

22. Reasons the Data Center is starting to migrate to Linux on System z
Ease of consolidation of potentially thousands of servers
Small < 100 user database system was first
Next was up to 5 million a day user system moved
UNIX TECH REFRESH being moved to Linux on System z
IBM AIX
HP UX
SUN/Oracle Solaris
Windows where applicable
Application Servers
Web Server
Charged by CPU usage keeps you honest
CPU reduction project – Close to complete

23. Details on Reason 10
Lowest total cost of ownership, total cost per user, and total cost per transaction
Example – Cost Savings with IBM System z

24. Large Bank Saves $1.5M with System z
72% reduction in SW maintenance costs
95% reduction in connectivity costs
75% reduction in power/cooling costs

26. System z futures for a workload-optimized world
Re-write the rulebook and set new standards for business-centric IT with IBM System z, to be the world’s premier workload-optimized platform for enterprise applications.
Vision:
Deliver the best of all worlds, Mainframe, UNIX, x86 and single function processors, integrated in a single system for ultimate flexibility and simplicity to optimize service, risk and cost across multiple heterogeneous workloads.
So, with future generations we will breakthrough some of the barriers that limit the way we use IT today. The objective is to move away from today’s Silo-ed approach to IT where each platform is managed as a separate and distinct entity, and instead focus on managing across heterogeneous platforms to give an end-to-end solution view. This will enable IT resources and services to be properly aligned according to business viewpoint, rather than limited to an IT viewpoint
This new alignment will enable resources to be optimized to give the right level of service with appropriate risk at the right cost to the business.
