•Real life experience migrating to Oracle/Linux on System z

• Reference material

•Questions

History of zSeries SIG Group• User Group formed over 23 years ago

• One of the oldest Oracle SIG’s

• Started with Oracle on MVS

• Moved 8 years ago to include Oracle on Linux on System z

• z/OS Oracle de-support

• Small technical community and growing

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

Future of zSeries Oracle SIG Group• Join our Round Table Session on Monday 02:30 PM

• Oracle• IBM• zSeries Oracle SIG Committee

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

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

What System z Hardware Brings to Linux:• The most reliable hardware platform available

– 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

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

– Virtual network between LPARs, at memory speed– 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

Customer TrendsFrom 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

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

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

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

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)

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.

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

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

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

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.

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 projectSecurityEase 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
