of the ODA
platform
What people
are really doing
with ODA

What is ODA?
 Fast Intel compute nodes (2 @ 36 core/256-768GB)
 Shared, direct attached storage array including flash
 InfiniBand interconnect & 10Gb public networks
 Management software (database & virtualisation)
 Sold as a single product for $68k (list)
in a slide!

Why ODA?
 Lots of x86-64 compute power
 Single product SKU so easy to order
◦ No “configure to order” set of components to choose
◦ You know everything works together
 Commodity pricing
 Complete stack supported by Oracle
 ODA VP is a complete virtualization solution

Database with DR / Test
Use Case & Requirements
Trade Agency
 Need test DR on regular basis
◦ without impacting the production
◦ DR test must include all stacks including network, storage, sites up to database & application
 Production DR cannot be used due to the risk of real site outage during test
 Minimize overheads (resources, time) to maintain DR
 Minimize license requirements
 Quick & easy migration from old (Windows) environment to new


 Each database with 2 standbys
◦ Production standby – only for DR
◦ Test Standby – Regular DR Test
 Consistent hardware & software
between all sites
 Minimum cores use for Test standby
ODA

Learning
 ODA’s consistency of software, hardware between 3 sites
 simplifies management, reduces resources
 Minimum license is enough to run test standby box - even it can
host some non-production databases
 No previous OVM experience but auto-management of ODA &
oakcli helps with smooth transition from Windows to Linux

 Database with Golden Gate
ODA
Bare
Metal

Database with GG
Financial Sector customer
 Application and DB have to be up 24x7 due to the nature of business.
◦ Oracle shop but little experience with Oracle HA solution such as RAC
◦ Regular maintenance window adds up to downtime
 Company acquisitions meant data centers in 2 cities
 Hardware refresh is due


Database with GoldenGate
Learning
 Golden Gate not only helps to scale up beyond 2 compute nodes but also helps with
other areas which were not the initial goal such as
◦ Minimize application release downtime
◦ Minimize Database upgrade
◦ Flexibility of having solid rollback option for major changes/release
 ODA platform frees up DBA to concentrate more on GoldenGate active-active
operation and tune up instead of dealing with day to day RAC or DB issue
 Minimize Golden Gate license (ODA supports Hard Partitioning)

 Database with Data Guard
ODA

Platform

Database on ODAVP
Public Sector
 DR is critical to the business (the need was realized after
several incident including long power outrage on main site)
 VMware was in place but unsatisfactory (expensive, not DB-
aware)
 Need to reduce DR licenses compared to current


Virtualization for DB deployment only

Learning
VM No-VM
Scale up and down
(CPUPOOL)
Scale up Only
(Core config.)
 No migration path from ODA BM VP : one time choice
 Why use ODA VP platform for just database deployment?
◦ Scale up and Scale down
◦ Licensing (minimums)
◦ Non –EE database deployment

Database on ODAVP
Learning: Minimum Licenses
 For standby database 2 cores is often sufficient to log apply
◦ In case of disaster and primary site is fully down  licenses will be moved to standby sites
 ODA X3-2 has a 4 core minimum for Bare Metal (2 core for all other models)
◦  go VP on X3-2 for 2 core minimum
BARE METAL

WebLogic 12c for Custom Java App
Health Insurance provider
 Migration from VMware on blades – need Oracle VM for license partitioning
since modern processors have many cores
 Self-contained “application in a box”
 Lifecycle operations of ODA upgrading means WLS + DB on one ODA is
logical
◦ ODA non-rolling patching needs downtime so easier to affect both tiers of a few
environments than database tier for all

Learning
 Disaster Recovery for non-permanent DR is tricky
 Lack of backup solutions – nothing elegant
 WLS ODA templates work with minimal changes
 Previously had some re-write rules etc in OHS – needed
changing for OTD
 Very robust – “just works”

Management Station
Learning
 Only follow ODA documentation
◦ E.g. do not get creative with OVM stuff
◦ Except when using VLANs for ODA: get creative!
 Plan shared repo vs local repositories thoroughly
 Choose an experienced ODA implementation partner
◦ E.g. cabling mishaps, important initial provisioning choices

 Databases licensed by both Processor (pre-prod) & NUP
(test) on a single ODA
 Simplicity & speed of cloning
 ODA has sufficient cores/processing for test envs but
insufficient storage / IOPS

Learning
 Don’t let shared repo fill up! (caused an outage)
 vDisks – done manually, now possible with oakcli
 Quite a lot of work to set up & overlap of lots of
relatively new technologies (LXC, BTRFS, ACFS).
 One VM kernel per node – reboot needs outage of all
databases
This was pre-ODA 12c – now could use ACFS clones.
Oracle still needs to address multi-license scenarios on ODA though.

backup)

 Consolidation Platform (App & Database)
ODA
Virtualized
Platform

Consolidation
Education
 Variety of platforms (AIX, Windows, Linux)
◦ Hard to troubleshoot
◦ Costly in terms of resources, management of team and maintaining the
environment
◦ Different vendors, support and licensing, patch cycles
 No DR situation raised concerns


Consolidation (App & Database)
Learning
 2 ODAs were capable to address all needs including DR
◦ Bonus: included other smaller environments not in plan
 Simpler and better HA solution
◦ Automatic application VM failover (even with no clustered WebLogic)
◦ Quick DB instance recovery in production due to RAC deployment
 Ability to test changes ahead of production deployment in QA
◦ Same platform, same software, same hardware

 ODA- Oracle application in a box

Oracle application in a box–
Public Sector, Insurance
 Consolidation
 Agile environment – need to spend less time on ops and more on
deploying new functionality
 Solution needs to fit in with controlled network access


Learning
 Migration of Oracle application on ODA :
 Fresh install
◦ Start with Oracle-ready template
◦ Move application to new install
 Migration
◦ Upgrade DB to 11gR2 (at least)
◦ P2V or V2V to move application to ODA
◦ Reconfigure application – Ebiz rapid clone

Learning
 ODA is ideal for segregating application traffic from database traffic
Simple physical segregation, no need for VLAN (though VLAN also possible)

ODA – OracleVM Server Platform
Transportation
 Mandatory security zones enforce to have physical server in
◦ Application tier zone
◦ Database zone
 Optimize application license utilizing OVM (hard partitioning)
 Require massive VM deployments (automation)
 Quick migration/deployment
 Lack of OVM skillset


Multiple ODAs
Each node has 10’s of VMs on it
ODA – OVM Platform

Learning
 ODA price-wise looks promising compare with other Oracle Eng system.(goal: lower License cost)
 OVM world look simpler in ODA (no OVMM) and with oakcli. (No need to have big transition
from VMware to OVM to manage the new Env.)
 Shared repository makes ODA shared storage to be accessible to appVM (except SSD)
 ODA features make it competitive in the market (no extra cost)
◦ VM snap clone
◦ VM automatic failover
◦ VM migration

Learning
 Automation of massive deployment is very feasible

• How to inject network configuration into VM created from template:

ODA Strengths & Weaknesses
 Ease of use, especially patching
 Simple OVM
 Memory expandability (up to 768GB per node)
 Single point of supply & support
 Community
? ODA has powerful processors (72 cores)… too big?
 Lack of IOPS for HDD – flash useful but relatively small
 Downtime during infra patching
