There are certain dictionary views available to monitor the Exadata cells from the database.One of the view is gv$cell_thread_history.

Oracle with 20:20 Foresight Perth Australia was awesome

Perth is far from everywhere, but not far from the Oracle technologies. Passion, knowledge, and urge to share the experience, skills, tips and knowledge brought people from across the planet to gather under one roof and learn, educate and network under the banner of Oracle with 20:20 Foresight.

The event was organized by the Australian Oracle User Group with many other sponsors and exhibitors and was a explosion of innovation. Where there is Oracle on this planet, Pythian is there, rest assured. We presented three papers during this mega conference in West of Australia. Yury Velikanov presented on Direct NFS, (more...)

It’s Your Holiday, Not Your iPhone’s

I was thumbing through the photos in my iPhone from my Melbourne trip of August, where I went to present two sessions on Exadata in Insync12.

I spent couple of hours on first and last day in sigh-seeing or should I say my iPhone did the sight-seeing, and I nursed him. As I was going through the photos, I realized I was kind of watching those places first time. There were many things which were present in the photos, but I never saw them with my own eyes while walking or traveling in the trams or cabs.

I have decided (more...)

Get Oracle Database Appliance on Peanuts Rates from Pythian

When I first arrived in Australia, I was so stressed to see mega, urgent, limited supply sales at crash-door prices everywhere at Coles, Woolworths, Harvey Norman and other mega supermarkets. I wanted to go and buy all the stuff as I thought there would be no tomorrow and this is the once in a life time chance.

For instance I wanted to buy hundreds of liters of milk because it was on special rate and they said that it won't last long. Now after almost an year, not only the milk stands at the same special rate as it was (more...)

Oracle Exadata 11g Certified Implementation Specialist in Australia

I have been working with Exadata systems for the last two years and have loved every moment of it. Pythian's challenging and learning environment makes it a great experience. I thought of checking my Exadata know-how by attempting the Exadata certification, and thankfully passed it and became Oracle Exadata 11g Certified Implementation Specialist.

Yes quite a mouthful title, but nonetheless a good one. 

I will be writing another post as how to become an Exadata certified professional without using Exadata soon. 

My Exadata Sessions at Insync12 Melbourne Australia on 22nd August

About Insync: The InSync12 Conference and Exhibitor Showcase is a joint event of the Quest ANZ user group – representing JDE and PeopleSoft customers, and the Australian Oracle User Group (AUSOUG) representing the Technology, Development and Applications users.

set fileformat=unix

Short, sweet and very useful.

Was running a shell script in Linux to execute some SQL, and got the following error during start of script:

^M: bad interpreter
 
Yes, received the script from the windows.
 
Now to rectify this, open the script file in VI editor and give following command:
 
:set fileformat=unix
 
save it with :wq
 
and run it again.
 
Should Run like a beaut.
