Agenda
• The role of the OS in applicaBon delivery • Oracle’s two OS’s • Key advantages of each OS • WHY TWO??? • How should I choose? • Summary

Unix and Unix Like?

The role of the OS in applicaBon delivery
• What does the OS actually do for us? • Do some do different jobs bePer than others? • NaBve OS features versus bolt-‐on features • The OS is NOT unimportant – even (or especially!) on Hypervisors

Oracle’s two OS’s: Solaris and OEL
• Solaris – Acquired in the purchase of Sun – Best scaling OS – Largest install base of large Oracle installaBons – Leader in performance and scale in many categories
– Support for SPARC and X-‐64 systems from many vendors
– Comfortably scales beyond 512 threads, TB’s of memory, hundred of I/O adapters

Oracle’s two OS’s: Solaris and OEL
• OEL – refined from the Red Hat source base – Now Includes Unbreakable Enterprise Kernel by default
– CAN be fully Redhat compaBble – Supported by Oracle for enterprise DB before any other vendor
– Used in original Exadata

Upgrading or starBng fresh

Key Advantages of OEL
• Is Linux! (Some organizaBons, and ISV’s require it, aPracBve development environment.)
• Can leverage the global community in terms of available applicaBons and OS development
• Has the mindshare as ‘Linux’, which is separated from UNIX
• Support on a variety of hardware; though OEL is only X-‐64.
• Support for many devices

Key Advantages of OEL
• Has Bered support pricing (Network, Basic, Premier)
• Is more familiar to School/University leavers than UNIX
• Has the OVM Hypervisor as an opBon, which can contain OEL, Solaris, Windows, etc.

Key Advantages of Solaris
• Support for SPARC hardware – T-‐series systems
• Best performance per waP • Up to 512 threads in 5RU • Consolidate old Solaris systems whilst barely breathing
– M-‐series systems • mainframe like reliability • HA with No Single point of failure in large scale systems • Hardware Domainable

Key Advantages of Solaris
• Fastest, highest scaling, most resilient, more widely supported UNIX
• KEY OS capabiliBes that include
• Resource Management • SMF • FMA • Full support for LDOMS • Wholly owned
• Dtrace • ZFS • Containers • SMF • Branded Containers

Why BOTH?
• Opportunity to make the best of all worlds: – Tightly integrated and opBmized for the total Oracle stack
– Opportunity to shape the OS as Silicone is developed, and take advantage of it first
– Tightest integraBon with Oracle DB – Build largest, most resilient and scalable systems – Many elements CORE to the OS, rather than bolt-‐on.

Why BOTH?
• OEL – Broad compaBbility with Linux Ecosystem – Pricing opBons – Choice of Kernel; Faster and bePer scaling Unbreakable Enterprise Kernel, or the fully RedHat compaBble Kernel

Wonder Twin Powers: AcBvate!
• Both OEL and Solaris can be managed by OEM Ops Centre
• Using OEM, both can be supported by the one support team from an operaBonal perspecBve
• Regular configuraBon to use OEL in smaller web-‐facing environments, and Solaris on the larger systems in the back-‐end
• ‘Red Stack’ – It’s actually not just a markeBng thrust.

How do I choose?
• SOE / Strategic Architecture / Vendor ojen determines rather than choice
• Where more business criBcal, higher value transacBons are involved, Solaris is typically a bePer choice – even if only for DTrace, SMF and FMA.
• Horizontal, node based scaling typically targeted for OEL.

The best of both worlds • Whether you want speed, scale, access to the most packages, best tools, greatest diagnosBc capabiliBes, highest resilience, Oracle has you covered in the Linux/Unix space.
• OEL 6 has released, now with unbreakable kernel by default
• Watch this space for Solaris 11 – There is an Express Version already Available
• Wait and see what the next GeneraBon SPARC T-‐series systems can do!
The most comprehensive Oracle applications & technology content under one roof
Summary: • Typically not as simple as one or the other • If you are leaning towards verBcal scale and high value business transacBons, Solaris
• If you need greatest reliability or diagnosability, Solaris
• If you are leaning towards lower cost compute, or business transacBons, OEL
• If you have a need to get or use more of the ‘linux /opensource’ community sojware, OEL.
• Frequently use both!
