If you are wondering why anyone would possibly need to Install Oracle VM Manager in such an unsupported way, please read my previous Oracle VM 3 related blog post.
In this post, I will share with you my experience installing OVMM 3.0.3 under OVM 3.0.3 Dom0 host, including:
- A short and sweet action plan to get it up and running ASAP
- A detailed explanation with error messages and solutions
- Clean run output

I have decided to share with you some of the real life examples of why sometimes V$ views may hide real resources utilization numbers. As AWR and STATSPACK (previous version of AWR) as based on V$ views those may reflect the wrong statistics as results of the issues I am going to discuss in this blog post.
Please don’t get me wrong, I still believe that V$ and related frameworks are a great source for performance diagnostic (sometimes;). The point I am would like to make is you need to be careful reading statistics and do not take anything reported for granted.
This is my first blog post on this topic. I am planning to show you more interesting examples in the next posts. Read the rest of this entry . . .

I returned from AUSOUG conference in Perth (Australia) just last week. This blog is my report from the conference for the days 0 and 1. I have spent several days helping my family recover from sickness and had a short brake before getting back to normal and up to speed with day to day duties. Now I am ready do this report for you.
My flight from Sydney to Perth went well and I managed to write an application for a new internal position at Pythian plus went through my presentations’ slide-desks several times (I was about to present 2 presentations). The interesting thing about the flight from Sydney to Perth is the fact that it is by 1 hour longer than other way around (5 against 4 hours). I assume it is because of the earth wonder twisting :) Read the rest of this entry . . .

If you haven’t considered attending the AUSOUG conference in Perth yet, you definitely should! Out of 50 sessions I counted 21 to be presented by Oracle ACEs and Oracle ACE Directors; 8 by Oracle employees and at least 2 by Oracle Certified Masters!
Thanks to the conference organizers (including hard working Scott Wesley, Burke Scheld) and Oracle Technology Network team this years conference has a very impressive speakers list for the most remote city on earth! If you are base in Perth or close by :) you still have a chance to be part of the event! Read the rest of this entry . . .

This is a short blog post to give you my Apps DBA takeaway from Oracle OpenWorld 2011 in the context of Oracle Fusion Applications (new Oracle ERP/CRM/…+ product).
Initially in June/July this year as many of Oracle Apps DBAs I got very excited about the Fusion Applications technical availability on the eDelivery site. However getting some details I came to a realization that there are going to be very limited client hosted implementations in the coming year or so. Everything that I have heard during Oracle Open World just confirmed my current understanding.

A bit more than a week passed since most of us who been part of the OpenWorld are back from San Francisco. It is about time to start sharing stories on how it went for each of us. I must admit that it happened to be a very stressful OpenWorld for me personally. I am recovering from it slowly. On the positive side I met so many great people, discovered how supportive people are and how great is to be a part of the Pythian Team!
This was my second OpenWorld. My very first one was 10 years ago. This year I returned to San Francisco to present my experience working/implementing Oracle technology. This blog post is the very first blog post about Oracle OpenWorld 2011. I am writing about my most important personal experience bellow. I am planning to write more posts on Pythian & OTN Bloggers event, My takeaway on Fusion Applications, Oak Table dinner and may be something else…
Let’s talk about how my 2 presentations went at Oracle OpenWorld 2011. Read the rest of this entry . . .

Just before going to Oracle OpenWorld I would like to share with you a very good Oracle Support note on Automatic Memory Management (ASMM).
Common Cause for ORA-4031 in 10gR2, Excess “KGH: NO ACCESS” Memory Allocation [Video] [ID 801787.1]
Don’t be misled by the title of the note ( I would make it more generic if I was in charge). I think any Oracle DBA who switch on ASMM (init.ora parameter SGA_TARGET) should read though this carefully.
The note is full of significant technical details. I will leave it to you to read it carefully. In this blog post I would like to share with you the most important takeaway, from my point of view. Read the rest of this entry . . .

Last Thursday I spent in Melbourne presenting two of my papers for Australian Oracle User Group Victorian members. I received a very warm welcome in that beautiful city.
The first part of the day I spent in one many coffee shops, enjoying fantastic coffee, working and watching how the stream of people changes during the day. I wonder how it is possible that Australia’s two biggest cities are so different! The difference is quite difficult to describe. You should visit these sites to feel it yourself!

NOTE: 2012.02.09. For the 3.0.3 version’s installation instructions please refer to the post here.
Oracle just released Oracle VM 3. I am sure that there are many Oracle Infrastructure related professionals who would like to install it in their test environments and start evaluating the product. The problem is beside of the Oracle VM Server you need an Oracle VM Manager. Oracle VM Manager provides management interface for managing one or several Oracle VM servers. It appears that Oracle VM Manager requires a separate host with at least 6GB of RAM just to get it installed. In this post am explaining how you can install both Oracle VM Server 3 and Oracle VM Manager 3 allocating to both components just 1GB of RAM on the same logical server (Dom0).

Introduction
Just a few days ago I received a reminder email from Burke Scheld for the “AUSOUG National Conference Series – Perth 2011 – Call for Papers”. I had an event-related conversation with several Oracle guys in my professional networks and the answers I received triggered this blog post. Some of the very good Oracle professionals I personally respect said “…I am not sure what I would get out of it …” or “…I haven’t done anything exciting for the last FEW MONTHS …”.
The answers I received shocked me a bit. Read the rest of this entry . . .
