Introduction to Oracle VM Technology

5

Oracle VM Server: Xen Hypervisor,management domain dom0 Linuxkernel with support of devices,IO, networking, etc.

VM:guest OS with applicationsrunning on domU

Server partition: multiple guest

VMs run independently on a VMserver

Virtual CPUs and Virtual Memoryare signed for each guest VMAll 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.

Management: VM Manager and Enterprise Manager

Oracle VM3.o released in August, 2011.New Oracle VM Manager provides centralized managementScalability: up to 160 physical CPUs, 2 TB of memory

128 virtual CPUs and 1TB memory per guest VMApplication Driven Virtualization: VM template based

applications deployment

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 storageShared 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 templatesshared_disks: for virtual storage

VM Repository (OVM 3.x): root:/OVS/Repisitries/XXXXXXXXXXXXXXvirtualMachines: all virtual machinestemplates: see all the VM templates

Benefits of Virtualizing Oracle EBS with Oracle VMServer partitions and consolidation

High availability and scalability

Deployment standardizationFast deploymentDramatically 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 :

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 9207542ebiz_1211_reconfig.sh , ebiz_1211_cleanup.sh

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 andcustomization

Migrating the existing EBS instance to virtual environmentAfter the migration, we can:

Create new EBS templates based on the migrated VMs Create new EBS instances using on the VM templatesNew way to deploy new EBS instance

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

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
