Oracle Enterprise Linux 5.5 Installation on HP DV6 Quad Core with 8Gb RAM Notebook

Oracle Enterprise Linux 5 Update 5 Installation on HP DV6 (I7 700 Series) Quad Core 8GB RAM panics with Kernel panic - not syncing


At the boot prompt use "linux acpi=off" , this will help you overcome the above kernel panic error mentioned and puts one more in front.

In the next screen, it will prompt you to select the media location. If you are installing using CD it will prompt you to select the driver for the CD in the next Screen. If the driver name is not listed for the drive you are using....you are in trouble.

To overcome the driver selection hurdle, perform a media check for the CD and wait for the media check to complete and press Continue. This will take you further in the installation process.

You can find more information about ACPI here.

Enjoy !!

Steven Chan's "Identity Crisis: Are Patches to EBS 11.5.9 Equivalent to 11.5.10?"

I was going through Steven Chan's "Identity Crisis: Are Patches to EBS 11.5.9 Equivalent to 11.5.10? - very well explained from Oracle and Support perspective for Apps customers, gave me a food for thought and hence this post of mine.

From Apps DBA perspective, the way to resolve this confusion is to follow the simple checks.

#1. Check the release name/Applications version using the sql .

select release_name from fnd_product_groups.

#2. The patch readme is the ultimate source of truth to know if the patch can be applied for 11.5.9 instance. Lets take up an example of applying ATG Rup 4.

Pre-requisite section of Read me for 11i.ATG_PF.H.RUP4 (4676589) points out this very clearly.

==End clip==

So, for Apps DBAs source of truth should be patch readme and I guess there is no Identity crisis out there.

Enjoy !!

vi for Apps DBAs (2)

Happy Independence Day !! - August 15th 2008.

Its been a year I started blogging. I started my first post with vi for Apps DBAs on Aug 15th 2007. It was a great experience being part of the online community. I admire and I'm inspired by seeing the time and efforts put in by the fellow bloggers in the world to share their experiences. No wonder blogging is a great platform to convey, express and educate yourself. Happy blogging. !!

Following are great blogs I came across.

Steven Chan's - I like the controlled words and constant updates he provides.
Ask Tom - How many hours in a day he has got ? :) I admire the time he spends in answering questions.
Krishna Kumar's (Thought Clusters) - he articulates very well.

This August 15th, I would like to post Part 2 of vi for Apps DBAs.

How to copy multiple text strings located at different places in a file and paste em whenever you want and retain the selection till the time you quit the file ?

Interesting ? Read on...

Assume you have "Tom" located at line 1 and "Jerry" located at line 10.

Go to line 1: "ayy
Go to line 10 :"byy

Lines 1 and 10 are retained in the buffer a and b till the time you quit the file or over write the buffer with the new text. Now it is very simple to get Tom and Jerry whenever you need :).

To get "Tom" : "ap
To get "Jerry" : "bp

Thats all Folks !! :)
