Introduction to Oracle VM Technology

5

• Oracle VM Server: Xen Hypervisor, management domain dom0 Linux kernel with support of devices, IO, networking, etc. • VM: guest OS with applications running on domU • Server partition: multiple guest VMs run independently on a VM server • Virtual CPUs and Virtual Memory are signed for each guest VM All network and storage IOs of guest VMs go through Dom0 • VM Server Pool: an autonomous region of VM servers. • VM Servers in a VM server pool share Pool: an autonomous storage to provide high availability. • VM can be failed or live migrated to other VM server of the same VM server pool.

6

• Management: VM Manager and Enterprise Manager

• Oracle VM3.o released in August, 2011. New Oracle VM Manager provides centralized management

Scalability: up to 160 physical CPUs, 2 TB of memory 128 virtual CPUs and 1TB memory per guest VM Application Driven Virtualization: VM template based applications deployment

7

• VM Server Pool and VM Repository –HA enabled in server pool and VM level –Fail over and live migration of VM to other VM server. –All the VM servers in the VM server pool share storage –Shared storage: based on OCFS2/NFS-based for VM Repository. – VM Repository (OVM2.x): root: /OVS/ running_pool: all VM images seed_pool: all the VM templates shared_disks: for virtual storage –VM Repository (OVM 3.x): root:/OVS/Repisitries/XXXXXXXXXXXXXX virtualMachines: all virtual machines templates: see all the VM templates virtualDisks: for virtual disks storage Assemblies: VM Assemblies

• Guest VM creation –Paravirtualization and Hard Virtualization –Create VM from a VM template using VM manager –Create VM from an install tree using virt-install

Virtualizing Oracle EBS with Oracle VM

8

• Benefits of Virtualizing Oracle EBS with Oracle VM –Server partitions and consolidation –High availability and scalability –Deployment standardization –Fast deployment –Dramatically reduced cloning time

• Certification of Oracle E-Business Suite on Oracle VM: Oracle EBS is certified to run on Oracle VM 2 and VM 3.0.2 & later :

Metalink note: 465915.1 and Steven Chan:

• Oracle VM Templates for Oracle E-Business Suite

– Oracle VM Template Concept

– Consists of two virtual machines: EBS apps tier and EBS DB tier

– Downloadable template for Oracle EBS 12.1.1: Visions

VM template for Database tier VM: Vision demo DB

VM template for applications tier VM: Vision Demo instance • Oracle E-Business Virtualization Toolkit:

– What is virtualization toolkits ? Why do we need it? – The components of the virtualization toolkit: patch 9207542 ebiz_1211_reconfig.sh , ebiz_1211_cleanup.sh –Related Metalink documents: [977681.1], [975734.1]

• How to leverage Oracle VM for Oracle EBS Environment

–Need to establish Oracle EBS environment on VMs –But how? the process to create VMs and VM templates?

Fresh Install EBS on VMs , then build the template Use the Oracle EBS template from Oracle Migrate Oracle EBS from physical to virtual

• Process of Migrating Oracle EBS to Virtual environment –Streamline process ,no fresh installation needed –Preserve all the business data/logic, setups and

customization –Migrating the existing EBS instance to virtual environment –After the migration, we can: Create new EBS templates based on the migrated VMs Create new EBS instances using on the VM templates –New way to deploy new EBS instance

Global Marketing


11

• Leverage Oracle E-Business Suite Template from Oracle

–Oracle EBS VMs created from the template:

Include OS configuration for Oracle EBS (APPS and DB)

Include Oracle E-Business Visualization Toolkit

but it has not business data and customization and setups

–Combine EBS VM templates with Clone of EBS on physical system

VMs configuration + EBS VM toolkit from VM templates

Business data, customization and setups from physical system

Global Marketing


12

• Migration Process Design:

– Starting with downloaded Oracle EBS VIS VM Templates

–Build Oracle EBS VMs from the EBS VIS VM templates

–Replaced APPS and DB with the cloned copy from physical system

–Reconfigure and forms Oracle EBS DEV Instance VMs

–Create the new DEV VM template

–Create new EBS VMs from the DEV VM template

Global Marketing

POC Project Infrastructure

13

• Joint POC Project between Dell Solution Engineering and IT

– Develop a solution to migrate EBS from physical to VM

– Establish the VM template based EBS Instance deployment

for on-going Oracle EBS implementation project

• POC servers and shared storage infrastructure

– Physical Environment: Oracle E-Business Suite 12.1.1 x86-64 bit

APPs tier: Dell PE 2950 running Oracle Enterprise Linux 5U3

Database Tier: Dell PE 6950, Oracle Enterprise Linux 5U

– Virtual Infrastructure:

Oracle VM servers: 2 x Dell PowerEdge R810

Shared SAN storage: Dell EqualLogic PS6510 Storage ,

allocated 2TB for VM repository

VM Manager: 1 Dell PE2950 running VM Manager
