Mount extend partition - LVM using Knoppix LiveCD

Referenced from this article

- Burned a Knoppix LiveCD - version 5.1.1 (Newest:6.2)
(it has lvm-tools available)
- Booted the PC with Knoppix Live CD
- Started a Terminal

$ su
# lvm vgchange --ignorelockingfailure -P -a y
Code:

Partial mode. Incomplete volume groups will be activated read-only.
2 logical volume(s) in volume group "ubuntu" now active

It shows the name of the "volume group"


# lvm lvs
Code:

LV VG Attr LSize Origin Snap% Move Log Copy%
root ubuntu -wi-a- 142.92G
swap_1 ubuntu -wi-a- 5.89G

# mkdir /vg_mnt
# mount /dev/ubuntu/root /vg_mnt
# ls /vg_mnt/
Code:
bin cdrom etc initrd lib media proc sbin sys usr vmlinuz
boot dev home initrd.img lost+found opt root srv tmp var

# ls /vg_mnt/home/satimis/
all my work displayed here.


Inserted an USB pendrive and copied all my work on it.

# umount /vg_mnt

Now I have my work saved on the USB pendrive. Then I successfully copied my files on another PC.

修改GRUB開機順序

1.開機後打開終端機.
2. sudo gedit /boot/grub/menu.lst 開啟menu.lst檔案
3.找出default 0
4.把0改成windows開機的次序(注意:看windows是第幾個，若是是第3個則改成2-因為由0開始數)
5.存檔..重開機..

Fix Failed to execute child process "xscreensaver" in Solaris 10

/usr/dt/config/Xinitrc.tjds
/usr/dt/config/Xinitrc.jds


and log out

you will find this problem is fixed

solaris 10 加裝中文字體(繁體+簡體)

[參考文章 How to add languages on Solaris 10]

Solaris 10以後，用localeadm來添加語言，例如添加Japanese：

# localeadm -a ja -d

其它語言：zh_TW, zh_HK, hi_IN, th_TH, ko_KR, ja..etc.

Listing All of the Locales and Codesets
#localeadm -lc

Listing the Regions Available on a Solaris CD or DVD
#localeadm -ls -d /cdrom/cdrom0

XP 英文版 顯示中文與中文輸入

1. Start -> Control Panel -> Regional and Language -> 上方的 Language ->
   勾選 Install files for East Asian languages (此選項上面那個不要勾)
2. 再選上方的 Advanced -> Language for non-Unicode programs 選 Chinese(Taiwan)
3. 於 Code page conversion tables 選取所有相關 Traditional Chinese 的選項 -> Apply 就會開始安裝(需要 XP 光碟)
4. 重新開機完成後, 一樣到 Regional and Language Options -> 上方的 Language -> Details -> 會開啟 Text Services and Input Languages 視窗去新增輸入法
5. 就完成囉.

gcc instal on Solaris 10 SPARC

參考網站:

腳 本 之 家 www.jb51.net

Solaris 10 x86系統下安裝gcc過程

1． 系統環境準備

a. 由於系統默認的shell使用不太方便，所以將系統shell更改為bash。

# which bash

usr/bin/bash

# usermod -s /usr/bin/bash root

b. 建立系統 .profile文件：

# cp /etc/skel/local.profile /.profile

c. 在.profile文件中添加如下內容

PATH=/usr/bin:/usr/local/bin:/usr/ucb:/etc:/usr/sbin:/usr/bin:/usr/sfw/bin:/usr/ccs/bin:/opt/csw/bin:.

export PATH

export PS1='\u:\w#'

d. 從Solaris 10安裝光盤中安裝如下工具包

# pkgadd –d /cdrom/sol_10_1009_sparc/Solaris_10/Product SUNWwgetr
# pkgadd –d /cdrom/sol_10_1009_sparc/Solaris_10/Product SUNWwgetu
# pkgadd –d /cdrom/sol_10_1009_sparc/Solaris_10/Product SUNWwgetS
# pkgadd –d /cdrom/sol_10_1009_sparc/Solaris_10/Product SUNWgcmn

2． 下載gcc軟件

# /usr/sfw/bin/wget ftp://ftp.sunfreeware.com/pub/freeware/sparc/10/gcc-3.4.6-sol10-sparc-local.gz

# /usr/sfw/bin/wget ftp://ftp.sunfreeware.com/pub/freeware/sparc/10/libiconv-1.13.1-sol10-sparc-local.gz

# /usr/sfw/bin/wget ftp://ftp.sunfreeware.com/pub/freeware/sparc/10/libgcc-3.4.6-sol10-sparc-local.gz

# /usr/sfw/bin/wget ftp://ftp.sunfreeware.com/pub/freeware/sparc/10/libintl-3.4.0-sol10-sparc-local.gz

註：第一個為gcc的應用程序，下面3個為gcc的庫文件包

3． 解壓和安裝

# gunzip gcc-3.4.6-sol10-sparc-local.gz

# gunzip libiconv-1.11-sol10-sparc-local.gz

# gunzip libgcc-3.4.6-sol10-sparc-local.gz

# gunzip libintl-3.4.0-sol10-sparc-local.gz

#pkgadd -d gcc-3.4.6-sol10-sparc-local

#pkgadd -d libiconv-1.11-sol10-sparc-local.gz

#pkgadd -d libgcc-3.4.6-sol10-sparc-local.gz

#pkgadd -d libintl-3.4.0-sol10-sparc-local.gz

4． 修改 .profile文件

在 .profile文件中增加如下內容

export LD_LIBRAEY_PATH=/usr/local/lib:.

export CC=gcc

Matalb memory test

In Windos system
type "feature('meminstats')"

The Largest blocks show the maximum matrix size you can create


In official web of MATLAB, they say

Operating system	Process Limit
32-bit Windows XP, Vista and Windows 2000 (default)	2GB
32-bit Windows XP with 3GB boot.ini switch or 32-bit Vista with increaseuserva set (see later)	3GB
32-bit Linux	~3GB
64-bit Windows XP, MAC OSX, Linux or Solaris running 32-bit MATLAB	≤4GB
64-bit Windows XP, Vista, Linux or Solaris running 64-bit MATLAB	8TB

Matlab Install flowchart

a) Create the directory where Matlab will be installed ("/usr/local/matlab7").
Copy the "license.dat" file to the directory. Let us call this dir $MATLAB
from now on.

b) Run the installer and proceed with the installation.
cd /usr/local/matlab7
sudo /cdrom/install* &
%% display "Insert CD 2"
sudo umount /media/cdrom0
eject

c) Open the "license.lic" file and replace the string "your_host_name" with
the hostname of the computer where Matlab is being installed.

d) Copy the edited "license.lic" file to "$MATLAB/etc".

e) Now you are all set to run Matlab. Enjoy!
-------------------------------------------------------------------------------------
If your Linux is Debian, then you will meet some problems,
such as

Problem 1:
xxxxx:/usr/local/matlab7# /media/cdrom/install* &
bash: /media/cdrom/install: /bin/sh: bad interpreter: Permission denied

Solution:
Become root
Unmount CD-ROM
Make dirctory /cdrom
Give command: mount -t iso9660 -o exec /dev/cdrom /cdrom


After this go to the directory where you want to install the matlab. Put licence
file in that directory and from being in that directory give command:
/cdrom/install

Installation will start
Ref: http://www.linuxquestions.org/questions/linux-software-2/matlab-on-debian-232213/

Problem 2:
An error status was returned by the program 'xsetup',
the X Window System version of 'install'. The following
messages were written to standard error:

/tmp/5447tmwinstall/update/bin/glnx86/xsetup: error while loading shared libraries: libXp.so.6: cannot open shared object file: No such file or directory

Attempt to fix the problem and try again. If X is not available
or 'xsetup' cannot be made to work then try the terminal
version of 'install' using the command:

install* -t or INSTALL* -t
Solution:
According to some forums do:

# apt-get install libxp-dev

and then,
insert the MATLAB CD-ROM
XXXX:/usr/local/matlab7# sh /media/cdrom/install

However, I did follow the instructions of:
http://www.debianhelp.org/node/7432

1. Let run the install script so that it creates some environmental variables correctly.

2. Then
# cp /media/cdrom/update/bin/glnx86/libmwins.so /usr/lib

Check if you want to install the one of glnx86, glnxa64 and sol64 instead

3. Copy xsetup from the same directory to the install directory.

# cp /media/cdrom/update/bin/glnx86/xsetup /usr/local/matlab

4. From the install directory:

# ./setup

LATER when you run matlab you will see some errors associated to java

install java (http://www.java.com/en/download/index.jsp)

and then edit the file in bin/matlab

at the begining of the script (around line 180) write down:

# There is an error with the java that comes with MATLAB. Use the other java
export AWT_TOOLKIT=MToolkit
#export MATLAB_JAVA=/usr/lib/jvm/java-1.6.0-sun-1.6.0.10/jre
#export MATLAB_JAVA=/usr/lib/jvm/java-1.5.0-gcj-4.3-1.5.0.0/jre
export MATLAB_JAVA=/opt/jre1.6.0_12/

Finally activate the multithreading part in Preferences

ENJOY!
