ADV: RAC Attack Hands-on Event at Collaborate09

The RAC SIG, Oracle and IOUG are thrilled to present the hands-on event dubbed “RAC Attack!” at Collaborate09 in Orlando, FL. It is a half-day University Session in the IOUG Forum scheduled for the morning of Thursday, May 7th.

Each participant will have their own private RAC cluster to use. You’ll be able to install a new cluster, test session failover, perform backup and recovery and just about anything else you’d like to try (time permitting). The session will have lab outlines with very specific instructions that cater to beginners. Advanced users are welcome to test anything they like. If you try something that doesn’t work, we have mechanisms in place to help “reset” your cluster in 15 minutes and let you continue working and testing.

Here’s the official conference abstract for the session:

“Whether you’re new to or familiar with Real Application Clusters (RAC), you do not want to miss the IOUG RAC Attack! hands-on lab. The hands-on lab will cover: cluster installation prerequisites on Linux, installing Oracle clusterware, installing Oracle RDBMS, creating RAC database, failure testing and backup/recovery testing.

Also, you’ll have a chance to interact with some RAC experts from IOUG, Oracle and the RAC SIG, as they’ll be available to help you as you navigate the hands-on exercises. These volunteers are sharing their knowledge to help you be successful with your learning experience. This opportunity doesn’t come along often, so don’t miss a chance to pick the brains of our experts!”

There are still seats available for this event, but there is a limit, so don’t delay. It is an additional cost above the Collaborate09 conference registration, but I think you’ll find it to be packed with knowledge and experts to help you get the hands-on experience you need to grow and succeed with Oracle RAC. The session will be staffed with Oracle, IOUG and RAC SIG experts ready to help you and answer questions about RAC and clustering. Don’t miss out!

If you’ve already registered, you can add on the University Session by contacting IOUG. If you haven’t registered yet, there is still time left–sign up now!

Exadata front and center

Just in case you were like me and did not tune in for Oracle’s quarterly earnings concall, there were some interesting highlights. As many of you (well, there aren’t that many of you that read this, but…) know, I’ve been very interested in Exadata since its announcement at Oracle OpenWorld 2008 in October. While some observed that Larry’s introduction keynote was rather brief, I didn’t take it as a sign of disinterest at all. According to the concall earlier this week, quite the opposite.

Here are some choice excerpts from the transcript that I find telling about the future of Exadata:

Larry Ellison:

“So, that’s looking back. Now looking forward, I think the most exciting product we’ve had in many, many years is our Exadata Database Server.”

“Exadata is 100% innovation on top of our very large and very strong database business. And the early results have been remarkable. Charles Phillips will go into a lot of detail but I’ll just throw a couple of numbers out there.

One of our customers, and Charles will describe this customer, one of our customers saw a 28x performance improvement over an existing Oracle database. Another customer saw a monthly aggregation drop from 4.5 hours just to 3 minutes.

When compared to Teradata, a competitive database machine that’s been in the market for a very, very long time, another customer saw that we were 6x faster than their existing Teradata application, when using Exadata versus Teradata.

Another customer saw a batch process fall from 8 hours to 30 minutes. Charles will go into more detail on all this, he will repeat those numbers, because I think they’re worth mentioning twice.”

Charles Phillips:

“So now just a few comments by area. On databases, Larry mentioned, we’re very excited about how the HP Oracle database machine is performing. The increases have just been stunning and so we are getting great feedback from our customers and the pipeline is the largest build I’ve ever seen in terms of a new product.

And as he mentioned, the numbers are just stunning. The major European retailer who reduced the batch processing time from 8 hours to 30 minutes did not believe the process had completed. We had to convince him that’s actually how it’s done.

And so, as Larry mentioned, this is the reminder that this is an internally developed technology in the midst of all the discussion of acquisitions. People forget that we’re actually spending $3.0 billion a year on research and development and this is why we do it.”

From these snippets, you can see that the top executives at Oracle are excited about Exadata. If you’re a techie (if you’re not, how’d you get to this blog?), you’ll probably already know about Kevin Closson’s popular blog on all things related to Oracle and storage. Kevin is giving a webcast next week on Exadata where we expect he’ll discuss some of the technical workings of the product–deeper than the overview information many of us have heard before. If you’re interested, I strongly encourage you to sign up for the event and attend. There is no better authority on Exadata than Kevin and this is a great opportunity!

Congratulations New Oracle ACE, Jeremy Schneider!

I’ll be the first to offer a large congratulations to Jeremy Schneider on being the most recent appointment to the Oracle ACE program. He certainly deserves it (I nominated him, so I suppose I would think so) and I continue to look for great things to come.

Jeremy is the main creator of the IOUG RAC Attack! event that was held for the first time back in August 2008. He (with help from others) will also be putting it on as a half-day session at Collaborate 09. It’s a University Seminar on Thursday morning. All hands-on, all RAC, all the time. I’m looking forward to the event (I’m volunteering as a staffer). You should sign up now before it’s full! I can almost guarantee you’ll learn something.

Besides his work on this hands on lab/class for RAC, Jeremy has many other community contributions. His blog is full of excellent technical bits that always seem to come from a significant amount of research. He contributes occasionally to the Oracle-L mailing list. He also contributed some code to OCFS (v1) several years ago, so you can guess he understands a thing or two about programming and Linux, too.

His ACE Profile isn’t posted yet, but look for it to arrive soon. In the meantime, read some of the good stuff he wrote on his blog and look for him (and me too) at Collaborate in early May!

Congratulations, Jeremy!

Start Database Services automatically after instance startup

Those of us that have dealt with RAC environments for a while are familiar with the behavior of Oracle Services in an Oracle Cluster. Services are an essential component for managing workload in a RAC environment. If you’re not defining any non-default services in your RAC database, you’re making a mistake. To learn more about services, I strongly recommend reading the definitive whitepaper by Jeremy Schneider on the topic.

In an Oracle RAC cluster, services can be started, stopped, and relocated from one instance to another. However, if you have multiple services for your database, then it becomes difficult to start them at a cold start. Due to dependencies in Oracle Clusterware, Continue reading “Start Database Services automatically after instance startup”

Install to go-live, 3 days

This has been an interesting week, but not really that surprising.

I was called back to a previous client site where I had previously helped with some Oracle Application Server ( post-install configuration. In that previous visit, I got oriented to the environment they use and the packaged application they were deploying. The packaged application uses JSP, Oracle Forms, and Oracle Reports (possibly also Discoverer). The deployment environment is all Microsoft Windows servers with two Oracle Application Server homes per application server since the vendor’s deployment requires that JSPs be deployed in a separate O_H from the Oracle Forms and Oracle Reports environment (that’s the first eyebrow-raise I did, but whatever).
