3. Mount the iso file to as a CD image as the root user:
mkdir /OVMUP
mount -o loop ovmm-3.0.2-upgrade-b73.iso /OVMUP
4. Do a full database backup of the Oracle VM repository
database
5. As the root user, ensure the Oracle VM Manager is running:
service ovmm status
if not, start it up: service ovmm start
5. Run the upgrade as the root user:
cd /OVMUP

IOUG Virtualization Presentation Recording and Questions and Answers

kyuoracleblog — Tue, 29 Nov 2011 20:41:21 +0000

On Sept 21, 2011, Saar Moaoz from Oracle RAC Pack Team and I co-
presented an IOUG Virtualization online education session:
“Virtualizing Oracle 11g/R2 RAC Database on Oracle VM: Methods/Tips.”
This presentation was based on Oracle VM 3.0 technology, which was
released a few weeks before this presentation. After the presentation,
we have recieved a few questions about Oracle VM and RAC. Both of Saar
and I provided the answers for these questions. IOUG has posted the
QAs and the actual presentation video recording on IOUG IOUG Webinar
Archieve. I copied some of these quesions and answers as follow. For
more details and the actual presentation recording, please visit this link. You also can download the presentation pdf here.

Copy of the some Questions and Answers:

Q: Is there any written tutorials/white papers on how to setup a RAC
on an Oracle VM?
A: To use the RAC OVM Templates, http://www.oracle.com/technetwork/database/clustering/overview/rac-template-11grel2-166623.html. For whitepaper on RAC/OVM: http://www.oracle.com/technetwork/database/clustering/oracle-rac-in-oracle-vm-environment-131948.pdfFor RAC support on Vmware, it is supported, just not certified, see My
Oracle Support Note: https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&id=249212.1

Q: Is it supported to increase the size of System.img file (plenty of
approaches is available in the internet), since it is based on block
device and not LVM, which could eliminate this problem?
A: Yes, the templates are a starting point, you are welcome to tune/
tailor them further to your environments.

Q: Why should in production support template shared disk be on a local
disk? How different node from multiple host can access them?
A: Test deployment allows a special case, where the DB files are on
localdisks, in that case all VMs forming the cluster must run on the
same Dom0/OVS server. For production, shared disks must be used and
accessible from all Dom0/OVS Servers. “lsinventory” output is available
inside the zip file of each template, no need to create a VM, simply
unzip and look at lsinventory output.

Q: Can RAC on VM use ASM instead of OCFS?
A: RAC inside the guests uses ASM, not OCFS2. On Dom0, for the
repository, OVM may use NFS or OCFS2, but this places only the
OS/Oracle VM files, not the database which is in ASM as said before.

Q: Will there be an OVM setup for RAC One Node?
A: The current RAC OVM Templates support RAC ONE NODE. Simply follow
note# 1232802.1. Create a service, then use the convert database
command. Note the troubleshooting section at bottom of that article.

Q: Does the template work when you deploy virtual images on different
physical boxes and club them as nodes in RAC implementation?
A: Yes, the templates work for production (where each VM is on different
Dom0),or for test (where some or all VMs may be on same dom0).

Q: Installation instruction for installing RAC11g2 under OVM3?. pdf files
are for ovm 2.
A: The basic steps are the same. Import the template w/Manager, create
the VMs, attach shared disks, adjust CPU/Memory. The only catch is to
remove the xenbr0/1 on the template and map it to the bridge names in
OVM3. We will have a reference document to highlight only these
differences in some time.

Q: Do I need to install OVM 3.0 before I start applying my VM
templates for RAC database?
A: Yes. You need to install Oracle VM servers and VM manager
and configure the virtual infrastructure before using VM template.

Q: I am not clear how to proceed if I have bare bone server
A: Here is an outline of the steps.
1. Install Oracle VM server,
2. Install Oracle VM manager
3. Configure shared storage and networks on VM servers
4. Download and import the VM templates including RAC VM
template
5. Create VMs using templates
6. configure the virtual networks and virtual storage on VMs
7. following the step given by Saar to configure RAC on the
VMs. The first part of the presentation covers the virtual
infrastructure configuration (step 1-6) .

A Summary of My Experiences with the 2011 Oracle Technology Network Latin America Tour

kyuoracleblog — Sat, 13 Aug 2011 19:57:18 +0000

From July 5^th to July 23^rd, 2011, the 2011 Oracle Technology Network (OTN)Latin America Tour covered multiple countries ranging from Central America to South America. The tour’s purpose was to give a series of presentations on various areas of Oracle Technology. Led by Tom Kyte, the vice president of Oracle Corporation, the OTN tour speaker team consisted of world leading experts on Oracle Technology from Oracle Corporation as well as from the industry technology community. It was a great honor to be invited to join this speaker team to travel and speak with some of the industry’s legendary speakers: Graham Wood, Debra Lilley, Hans Forbrich , Francisco Munoz Alvarez, Ronald Bradford, Kuassis Mensah, Arup Nand and the great speakers from the local Oracle user group of each country.

The 2011 OTN Latin America Tour Speaker Team

On this OTN Latin America tour, I gave the following technology presentations at three South American conference sites: Sao Paulo, Brazil; Montevideo, Uruguay and Santiago, Chile:

Through these two presentations, I discussed the Oracle RAC and Oracle VM technology with the Oracle user communities of these three countries, and also introduced the engineering work we do at the Dell Oracle solutions engineering lab on Oracle databases, and Oracle VM and Cloud infrastructure. Additionally, I explained how the people in the user communities in these quickly growing economic regions can take advantage of these solutions to meet their business needs.

At first thanks OTN for the sponsorship of the tour. And I want to expecially thanks the event organizer Francisco Munoz Alvarez for his admirable efforts, and thanks the local user group leaders and team members who hard work made this great opportunity possible. It was delightful to see that the people in the Oracle communities in these three countries were very eager to explore the new Oracle technology. In two of my sessions in Sao Paulo, the audience filled the entire conference rooms. Brazil user group leader Eduardo Hahn and his team did an excellent job organizing this conference. I was also amazed by the excellent work and great hospitality of the wonderful Uruguay user group leaders Nelson Calero and Edelweiss Kammermann and their team. The conference in Chile was held in a great facility provided by a local private university. The conference’s audience was very attentive to the presentation content and they were very active in the QA sessions. Somtime the QA and discussions were even extended to after the sessions. Some of people brought up the related questions from their current systems to discuss.

The highlights also include the hospitality of the great friends and wonderful culture experiences and the incredible sightseeing in these countries. These also made this tour really memorable.

Really want to thank everyone for this wonderful memory and hope I can join the tour again next year!

The following sideshows are the memory of the tour.
