The document outlines a disaster recovery model utilizing Oracle Virtual Machines (OVM 3.1.1) and JD Edwards EnterpriseOne templates to mitigate disruptions caused by hardware or software failures. It details the setup of virtual machines for different server roles and outlines a backup strategy including regular cloning of VMs and daily Oracle database backups. The recovery process in case of catastrophic events is also described, including restoring databases and managing backups.

INTRODUCTION
A proposed disaster recovery model designed to mitigate any disruption caused by a massive failure in
hardware or software from an act of nature or human error.
The model takes advantage of Oracle OVM 3.1.1 Virtual Machines and JDEdwards EnterpriseOne Version
9.1, Oracle Linux 5 for small and mid-size companies.
HARDWARE
Two main identical Servers were used to implement the model: Dell PowerEdge T320, 2 Raid-1 (1
Terabyte HD) certified servers for Oracle VM.
No external storage (SAN Server) is used in this solution.

3. 3
ORACLE VM ENVIRONMENT
Oracle VM is the server virtualization offering from Oracle Corporation. Oracle VM Server for x86
incorporates the free and open-source Xen hypervisor technology, supports Windows, Linux, and Oracle
Solaris guests and includes an integrated Web based management console. Oracle VM features fully
tested and certified Oracle Applications stack in an enterprise virtualization environment. Oracle VM can
be freely downloaded through Oracle Software Delivery Cloud
DISASTER RECOVERY MODEL

4. 4
The model includes a cloned image of every JDEdwards Server including the Deployment Server.
VMENT1 – Enterprise Server (Oracle Linux 5)
VMDB1 – Database Server (Oracle Linux 5)
VMWEB1 – WebServer (Oracle Linux 5)
VMDEP1 – Deployment Server (Windows Server 2008 R2)
SAVING THE WORKING ENVIRONMENT
A. Cloning the Virtual machines
Cloning the Virtual Machines on a regular base (monthly or bi-weekly basis).

5. 5
B. Offline Virtual Machines Backups (Optional)
Virtual machines can be backed up to external devices in one single step.
- Stop the Virtual machines
- Copy the active server’s virtual disks and virtual machines directory to an external device

6. 6
C. Oracle Database Backups
The Oracle Backups are copied daily to the down level Server Machine from the Database Server
(VMDB1 – Virtual machine). The purpose is having backups in the cross active-inactive Server.
Oracle Backups are running on a daily basis on 15 Day Retention Model
(Level 0 and Level 1)

ONLINE DATABASE BACKUP

RECOVERING DATABASE IN CASE OF CATASTROPHIC EVENT
1. Start Virtual Machines that are operational. It should have a full operational Database.
2. Copy the latest backup files from x.x.x.991BK or x.x.x.992BK to VMDB1u01backups
3. Catalog the Backups
3.1 Logon to RMAN
 Rman target /
 Rman> catalog start with ‘/u01/backups’
 Or use EM Manager, option Manage Current Backups / Catalog adittional files

10. 10
 Restore the Full Database or the Production Tablespaces to current time.
 Also using recovering can be performed using RMAN
 Rman> Restore Database;
 Or recover in a point of time:
Rman> list backup of archivelog all;
Review the latest archivelog sequence
Rman> Recover database until sequence XXX;
 Rman>Restore tablespace <name>;
 Rman > Recover tablespace <name> until sequence XXX;
