Error message below you get when you remove a view failed where the view is corrupted

cleartool rmview -tag viewname

cleartool: Error: /view_stg/viewname.vws isn't a view: No such file or directory
cleartool: Error: Unable to remove view "/view_stg/viewname.vws".

Steps to remove the corrupted view:

cleartool lsview -long viewname
Tag: viewname
Global path: /view_stg/viewname.vws
Server host: servername
Region: region_ux
Active: NO View tag
uuid:9e9c4e46.3f5311dc.86cc.00:14:c2:65:50:79
View on host: zmy12vw1

View uuid: 9e9c4e46.3f5311dc.86cc.00:14:c2:65:50:79

cleartool rmview -vob /vobname -uuid 9e9c4e46.3f5311dc.86cc.00:14:c2:65:50:79
Can't remove view "/view_stg/viewname.vws" from VOB while view still exists.
Remove view /view_stg/viewname.vws" references from VOB anyway? [no] y
Removed references to view "9e9c4e46.3f5311dc.86cc.00:14:c2:65:50:79" from VOB "/vobname".

How to make UNIX / LINUX command in DOS

Well I usually work in Unix environment. And now get shifted to do work in windows environment. It take me more time to change my style and make me have a lot of error messages such as:

C:\>ls
'ls' is not recognized as an internal or external command,
operable program or batch file.

Here is the solution if you want to have same command in Windows as Unix or Linux.
Just download the zip file and extracted it to C: and set your user environment.

My First Experience with Compiling Fedore Core 6

Phew... Finally I made it! I have successfully compiled my first Linux Kernel in my life woww.. :D

Today I spent most of the time in testing the Fedora Core 6 Kernel Compile.
Before that I search for through the internet just for a better or a good guide. I found the one most useful to me (my opinion) http://www.howtoforge.com/kernel_compilation_fedora

When start following the guide and I have a perception to use my own user account instead of "root" account to compile the kernel by setting the user privillage as what the guide tutor me....

But after 5 hours testing following the tutorial.....
I finally give up and login as superuser account "root" to restart the tutorial steps. And I able to execute tutorial's commands without any errors message.

When come to compile and create rpm package step "make rpm", guess what ?!
I was exciting to wait it finish compile...... but......
I fall asleep zzzZZZZ...... waiting it to successfully compile.....

It totally taken 2.5 hours to finish compile it. Wow.... I read some blogs said they take 1.5 hours..... but mine.... > 1.5 hours... >2 hours... XD

I guess I can't compare with them. Why?!? Well......

My Fedora Core 6 actually is running as a virtual machine.... using VMplayer :P
Furthermore... I'm using a laptop...... a super slow performance laptop... ahahaa. But anyhow, it finish compiled :D

After woke up, I had my dinner and continue my final exploration to make it bootable in grub.....

I was happy when the first reboot is successful but.....
It lost the x-windows login X(...... Just left the terminal login....
I don't dare to believe it!!! What happen??!!!?....
I reboot again, this time i used different command, "reboot" instead "shutdown -r now".

The second reboot was very successful and my x-window is there...
Hoooray!!....
I hurry view the kernel version at terminal "uname -r".... Ohyess... I the kernel version I compiled... Yahoooooo!!

Well, my next step is to know how to compile "module" instead of "full" kernel.
:D wishes me success.
