Single Instance and RAC Kernel/OS upgrade

This document will serve as a guide for the Kernel and OS upgrade activities for

  1. Single Instance on ASM using raw devices
  2. RAC with ASM (using ASMlib) and OCFS2

Upgrading the Kernel and OS is easy and will just need some few commands. The critical part is the dependencies once the Kernel gets updated, so if you’re using ASMlib and OCFS2 you’ll notice that after the upgrade they’re not working anymore… you can’t startup the ASM, then if your OCR and Voting Disk are on OCFS2 the CRS stack wont start all because the RPMs of ASMlib and OCFS2 are (more...)

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.

The session will have lab outlines with very specific instructions that cater to beginners. Advanced users are welcome to test anything (more...)

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 (more...)

Security, Forecasting Oracle Performance and Some stuff to post… soon…

I’ve been busy this February “playing around/studying” on the following:

1) Oracle Security products (Advance Security Option, Database Vault, Audit Vault, Data Masking, etc. etc.). Well, every organization must guard their digital assets against any threat (external/internal) because once compromised it could lead to negative publicity, lost revenue, litigation, lost of trust.. and the list goes on.. I’m telling you, Oracle has a lot to offer (breadth of products and features, some of them are even free!) on this area and you just need to have the knowledge to stitch them..

I’ll recommend a great book on Security, (more...)

Received the Certification Kit of Oracle 10g RAC Expert Exam.

Dear Friends,

After a long wait, I have received the Oracle 10g RAC Expert Certification Kit in my hands today, as I have already taken this exam (1Z0-048) in the month of August-2008. More or less it took more than three months to reach in my hands.

Best of luck everyone who is preparing for the Oracle 10g RAC Expert Exam – 1Z0-048.

Check my other blog post on “How to prepare for 1Z0-048 - Oracle 10g RAC Certified Expert Exam.”

IOUG RAC Attack! … I surrender!!!

The Oracle RAC SIG and IOUG are putting on an event in a few weeks in Chicago, August 4th and 5th. It is called the IOUG RAC Attack! (awesome name, I wonder who came up with it). Since my current job entails supporting an Oracle RAC environment (2 5-node clusters) and we have some newer members who are a bit green in the RAC arena, I thought it would make sense to check into the event and agenda to see if it is worthwhile to send some people to this.

From looking at the agenda and the quality speakers they (more...)
