LabVIEW 7 express for Gentoo Linux

Hi guys I have Gentoo distribution and I want to install LabVIEW 7 on it I have tried but could not do it successfully can anyone tell me what do I need to have Lab View installed like if I need rpm etc, which ofcourse I do not have ,
any suggestion will be welcome
thanx alot

Perhaps needless to say, you do need a LabVIEW version for linux. A windows
cd won't install on linux...

Oracle 11g Express for Ubuntu Linux

Just like Oracle provided express edition for linux for 10g, will there be an easy to install express edition of 11g for linux? I mean via apt-get or debs or synaptic. Of course, synaptic being the easiest I have EVER seen oracle install on linux.
I want to try Linux as a developer, but installing 11g on linux the normal way is a pain. I do not want to spend days trying to install 11g on linux. I want to get busy doing something with 11g such as write queries and design databases.

Yes, sigh.
If only people could write what they mean!My apologies for not being adept at the language. But we have both been wrangling with my lack of
language skills for years, so we should be used to it by now.
>
Are you saying EE when you mean XE, perhaps?No. I meant EE using synaptic. Which does not exist. Which may explain why some people think the installation is difficult. The tools they have learned are not there and the fight to find or learn the alternatives is not pleasant.
And even the simple stuff may seem. difficult. Some people, including modern developers with IDEs, are very concerned about the difficulties of editing in Linux. In my Oracle on Linux courses, I see grown men near tears when I tell them to edit sysctl.conf ... you should see the visible relief when I describe gedit or kate.
You have been doing the baseline install for years - Back in the Red Hat 9 days, I'd been handing out the HJR Linux install (with your written permission) in my classes for years. So I expect us to get it done in a short time. Cookie-cutter boot, thru install Linux & Oracle, to tnsping shouldn't take us (you and me) more than 1.5-2.5 hours. (Especially if all we want is a basic data dump.)
But ... reading the docco, translating the steps into a manual sequence, and finding and running the synaptic equivalent to the documented rpm commands - aka a synaptic install - can take days. Heck, just reading the docco to get it straight under a certified distro can take days.
After that, OUI is simple, and (if the pre-reqs are clean) nearly fool-proof.
BTW - why do we have to fight with the pre-reqs? Why can there not be more variants of the SUSE-supplied orarun.rpm to do all that manual stuff?

Labview player for linux?

I have a Labview VI running on my Windows platform. I developed it using the Windows version of Labview 7.1. I used the Web Publishing tool to make the display available online. I have verified that I can see the display running in real time using IE on a Windows machine.
Other machines in our LAN are running Linux, and cannot view the site in real time. For example, Mozilla asks for a plugin, but I can not find Labview Player for Linux anywhere. Can anyone help me get the Linux machines to see the real time site that is being hosted from a Windows machine?
Thanks

I don't think that there is a plug-in for a linux system to be able to view the published LabVIEW front panel.
Wait! Try looking at this link:

All 10g oracle is under extended support, the XE 10g version was yanked from the download pages at about the time 10g went Extended.
Probably won't be able to get a download from anywhere under oracle.com but there might be a few sites that still have it hosted. Try google.

Oracle 11gR2 Express Edition on Linux Ubuntu 11.10 howto
h2. Purpose
This document outlines instructions how to install Oracle XE under Ubuntu 11.10.
Ubuntu or Debian based Linux is not on the list of supported operation systems according to the Oracle documentation at http://download.oracle.com/docs/cd/E17781_01/install.112/e18802/toc.htm. You may want to consider virtualization software like Oracle Virtualbox and install Oracle Enterprise Linux as a free and professional alternative to installing XE under Ubuntu. You can also download pre-build virtual machines that include Oracle XE. You can browse http://otn.oracle.com/community/developer-vm for more information.

h2. 1) Install Linux Ubuntu
The following assumes you have installed Ubuntu 11.10 Desktop Edition for AMD 64-bit, or upgraded from a previous version. Keep in mind that Oracle 11gR2 Express Edition is only available for 64-bit architecture. It is not necessarily a requirement, but I would not bother to install Oracle 11gR2 XE on a system with less than 2 GB of RAM installed. You can download Ubuntu for free at: http://www.ubuntu.com/download/ubuntu and install it using the default settings provided.
You can apply the latest OS patch-sets by clicking the power button icon in the upper right hand corner of the screen and selecting "Updates available..."
h2. 2) Remote Terminal
You will need command line access to perform the installation tasks. Select the top "Dash Home" button of the Unity toolbar and enter the word "terminal", or use CTRL-ALT-t. If you prefer to open a remote terminal session use SSH. Ubuntu does not come with a secure shell login by default. To install it, use the following command:
sudo apt-get install openssh-serverYou cannot login as root unless you set a root password using the "sudo passwd root" command. However, you can get root user access using the "sudo" command, which requires only to re-enter the password of your personal account. Access to "sudo" is controlled by the /etc/sudoers file.
The best way to establish a remote command line session as root is to login with your personal account, e.g.: ssh [email protected], and then type "sudo su -" to become root, or use "sudo <command>" to execute individual commands. If your account does not have "sudo" access you can login as root using "su - root", but will need to know the root password.
h2. 3) Install Additional Software
Oracle 11g Express Edition requires additional software that is not installed by default:
sudo apt-get install alien libaio1 unixodbch2. 4) Managing Swap Space
Oracle demands that the minimum swap space for Oracle Database XE is 2 GB (2095100 KB) or twice the size of RAM, whichever is lesser. Enter the following shell command to verify your swap space:
cat /proc/meminfo | grep -i swap
SwapCached:            0 kB
SwapTotal:       2095100 kB
SwapFree:        2095100 kBYou can increase available swap space by using a swap file as long as disk space permits. The advantage of a swap file versus a swap partition is flexible space management because you can add or delete swap space on demand as necessary. The following will create and enable an additional 1 GB swap file at system startup, located in the /home directory:
Login as root:
sudo su -Enter the following commands:
dd if=/dev/zero of=/home/swapfile bs=1024 count=1048576
mkswap /home/swapfile
swapon /home/swapfile
swapon -aCreate a backup of the original "fstab" file and add the new swap file:
cp /etc/fstab /etc/fstab.backup_`date +%N`
echo '/home/swapfile swap swap defaults 0 0' >> /etc/fstabExit from root and verify the new swap space:
exit
swapon -s
Filename                    Type          Size     Used     Priority
/dev/sda5                               partition     2095100     0     -1
/home/swapfile                          file          1048572     0     -2Swap space is not a substitute for installed RAM. Swap space is a safeguard that allows the system to move idle processes to disk before the OOM killer will begin to terminate processes in order to free up enough real memory to keep the system operational. The general rule for sizing the swap space depends on the size of installed RAM. If your system has less then 4 GB of RAM the swap space should usually be at least twice this size. If you have more than 8 GB of RAM installed you may consider to use an equal size as swap space. The more RAM you have installed, the less likely you are going to run into memory starvation, and the less likely you are going to need swap space, unless you have a bad process.
h2. 5) Modify Kernel Parameters
Oracle 11gR2 Express Edition requires the following Kernel parameters. Enter the commands exactly as shown:
Login as root:
sudo su -Cut & paste the following directly into a command shell (not a text editor):
cat > /etc/sysctl.d/60-oracle.conf <<-EOF
# Oracle 11g XE kernel parameters
fs.file-max=6815744
net.ipv4.ip_local_port_range=9000 65500
kernel.sem=250 32000 100 128
# kernel.shmmax=429496729
kernel.shmmax=107374183
EOFLoad and verify the new kernel parameters:
service procps start
sudo sysctl -q fs.file-max
sudo sysctl -q kernel.shmmax
sudo sysctl -q net.ipv4.ip_local_port_range
sudo sysctl -q kernel.sem The SHMMAX kernel parameter defines the upper memory limit of a process. It is a safeguard to stop a bad process from using all memory and causing RAM starvation. The Linux default is 32 MB. The official Oracle XE installation documentation suggests a value of 4 GB -1 bytes (429496729). Since Oracle 11g XE has a 1 GB memory limit, a smaller footprint will be a better safeguard for the complete system. Setting the SHMMAX parameter to 107374183 will be sufficient.
h2. 6) Oracle Home Directory
At the time of this writing, Enterprise Linux 6 is not supported for Oracle database yet. It is therefore not possible to confirm Oracle ext4 filesystem compatibility, which is default in Ubuntu 11. According to various information, ext4 may cause a performance problem for Oracle 11g database. The following will show you how to add a ext3 partition to your existing setup.
h3. 6.a) Resize the Root Partition
Provided you have sufficient free disk space, you should be able to resize the root partition to create an extra ext3 filesystem. Considering the 11 GB user datafile limit of the Express Edition, 18 GB should be more than enough.
You can use the free Gparted Live CD to shrink your startup volume. Gparted downloads are available at http://sourceforge.net/projects/gparted/files/gparted-live-stable. When burning the CD, pay attention to burn the raw .iso image and not the possibly "mounted" image. If you are using a virtual machine like Oracle Virtualbox, you can mount the .iso image directly. There are going to be a few prompts when the system starts from the CD, but you can press Return to accept the defaults.
When the Gparted window appears:
- Select your ext4 root partition, usually /dev/sda1
- Select the "Resize/Move" button from the toolbar.
- Enter 18000 into the "Free space following" field and press the Return key.
Be careful not not change the start of the partition!
- Click the "Resize/Move" of the dialog and then then the "Apply" toolbar button.
The process may take several minutes - do not abandon it!
- Select the new unallocated free space of ~ 18 GB and push the "New" button.
- Set the file system to "ext3" and label it "oraclexe" and click the "Add" button.
Be sure to label it oraclexe, otherwise the follow-up instructions will fail.
- Finally select "Apply from the toolbar to apply the changes.
- Quit "Gparted", select "Exit" from the desktop and choose "Reboot" to restart the system.
{code}
After the system has restarted, open a terminal command shell.
Login as root:
{code}
sudo su -
{code}
Backup "fstab" and add the UUID of the partition. The "tr" command remove the quotes:
{code}
cp /etc/fstab /etc/fstab_`date +%N`
uuid=`blkid | grep oraclexe | awk '{print $3}'`
uuid=`echo $uuid | tr -d '\042'`
echo $uuid
echo "$uuid /u01 ext3 errors=remount-ro 0 1" >> /etc/fstab
{code}
The UUID is a unique number and should look similar to:
{code}
UUID=d1db753e-b5dd-4a4c-a61e-259c69867b58
{code}
Restart the system:
{code}
reboot
{code}
Verify the success:
{code}
df -h /u01
{code}
h3. 6.b) Setup External Storage
If you prefer to setup an external drive to install Oracle XE, beware that it can be a fatal mistake to make an entry in /etc/fstab to automount your external storage device. An unavailable device in /etc/fstab will prevent a system startup and prompt for appropriate actions at the console.
The following is an example of how to prepare an external storage device to be used for Oracle 11g, including a script to automatically mount an external drive at system startup without the disadvantages of /etc/fstab. The script will also take into consideration that a device name might shift if you attach additional devices.
To find out which USB devices are connected:
{code}
sudo parted -l
{code}
Look for the device that matches your USB storage. For example: /dev/sdb1
{code}
Model: USB 2.0 Flash Disk (scsi)
Disk /dev/sdb: 2064MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start   End     Size    File system Name     Flags
1      20.5kB 1929MB 1929MB hfs+         mystick
{code}
Initialize the device using ext3 filesystem - this will erase all data. The "-c" option will check for bad blocks (read-only), "-L" is the volume label:
{code}
sudo umount /dev/sdb1
sudo mkfs.ext3 -c -L oraclexe /dev/sdb1
{code}
Install the pmount distribution package:
{code}
sudo apt-get install pmount
{code}
Login as root:
{code}
sudo su -
{code}
Cut & paste the following into the command prompt (not a text editor):
{code}
cat > /etc/init.d/oracle-mount <<-EOF
#! /bin/sh

h2. 7) ORA-00845: MEMORY_TARGET
Oracle 11gR2 XE under Ubuntu 11.10 will result in "ORA-00845: MEMORY_TARGET not support on this system" either at Oracle database startup or during the initial installation. Ubuntu 11.10 uses a new version of the "systemd" system and session manager and has migrated away from /dev/shm and other common directories in favor of /run.
There are several ways how to address the problem. You can either enable /dev/shm shared memory, or change the default memory management of Oracle 11g from AMM (Automatic Memory Management) to ASMM (Automatic Shared Memory Management) as it was in used the previous 10g version. Since AMM is one of the new features of 11g, the following will show you how to make to make AMM work.

h2. 8) Installing Oracle 11gR2 Express Edition
The final release version of Oracle 11gR2 Express Edition can be downloaded for free at http://otn.oracle.com/database/express-edition/downloads. The software should automatically downloaded into the "Downloads" folder of your home directory.
Enter the following commands to unpack the installer:
{code}
cd ~/Downloads
unzip oracle-xe-11.2.0-1.0.x86_64.rpm.zip
rm oracle-xe-11.2.0-1.0.x86_64.rpm.zip
{code}
The Debian Linux based package management of Ubuntu is not compatible with the Red Hat package manager. The Oracle installer needs to be converted using the following commands:
{code}
cd ~/Downloads/Disk1
sudo alien --to-deb --scripts oracle-xe-11.2.0-1.0.x86_64.rpm
(This may take a few minutes)
rm oracle-xe-11.2.0-1.0.x86_64.rpm
{code}
The following needs to be set for compatibility:
{code}
sudo ln -s /usr/bin/awk /bin/awk
sudo mkdir /var/lock/subsys
{code}
Ubuntu uses different tools to manage services and system startup scripts. The "chkconfig" tool required by the Oracle installer is not available in Ubuntu. The following will create a file to simulate the "chkconfig" tool.
Login as root:
{code}
sudo su -
{code}
Copy & paste the following *directly* into the command prompt to create a file:
{code}
cat > /sbin/chkconfig <<-EOF
#!/bin/bash

By default, the Oracle Database XE graphical user interface is only available at the local server, but not remotely. The following will enable remote logins:
Login as the Oracle user:
{code}
su - oracle
{code}
Login as SYSDBA and execute the following:
{code}
sqlplus / as sysdba
SQL> EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
exit
{code}
See http://download.oracle.com/docs/cd/E17781_01/admin.112/e18585/toc.htm for more information.
h3. a) Unity desktop configurations
The Oracle XE menu under the previous Gnome Classic desktop shows several useful scripts to backup the database, start and stop the database, etc. Under the Unity based desktop this menu is not available. You can either switch to the Gnome Classic desktop as outlined in chapter 2, or perform the following steps to modify and copy the scripts as outlined below. The start and stop database scripts will also be modified to perform a progress feedback.
Login as user root:
{code}
sudo su -
{code}
Convert desktop files:
{code}
cd /usr/share/applications
sed -i 's/Categories.*/Categories=Database;Office;Development;/g' oraclexe*
sed -i 's/MultipleArgs/X-MultipleArgs/g' oraclexe*
sed -i 's/MimeType.*/MimeType=application\/x-database/g' oraclexe*
sed -i 's/.png//g' oraclexe*
sed -i 's/Terminal=false/Terminal=true/g' oraclexe-startdb.desktop
sed -i 's/Terminal=false/Terminal=true/g' oraclexe-stopdb.desktop
{code}
Exit root:
{code}
exit
{code}
Login as user Oracle:
{code}
su - oracle
{code}
Modify database start and stop scripts:
{code}
cd /u01/app/oracle/product/11.2.0/xe/config/scripts
cp startdb.sh start.sh_orig
cp stopdb.sh stopdb.sh_orig
sed -i 's/>.*//g' startdb.sh
sed -i 's/>.*//g' stopdb.sh
{code}
You will need SYSDBA privileges and set Oracle environment variables in order to use your regular user account.
Login to your regular user account:
{code}
su - dude
{code}
Enter the folowing command:
{code}
sudo usermod -a -G dba dude
{code}
Then update your profile to automatically set the necessary Oracle environment variables:
{code}
echo "" >>./.profile
echo '. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh' >>./.profile
{code}
Update your Desktop folder to contain useful Oracle XE scripts:
{code}
cp /usr/share/applications/oraclexe* ~/Desktop
chmod 750 ~/Desktop/oraclexe*
{code}
To verify success re-login and try "sqlplus":
{code}
su - oracle
sqlplus / as sysdba
{code}
h2. 10) Tips and Troubleshooting
h3. 10. a) Port 1521 appears to be in use by another application
Error: Port 1521 appears to be in use by another application. Specify a different port.This error happens after a previously unsuccessful configuration attempt using /etc/init.d/oracle-xe configure script. The script was able to start the Listener process, but most likely failed to continue to clone the database, e.g. ORA-00845. The following should correct the problem:
Determine the oracle listener process that is already running:
{code}
$ ps -ef | grep oracle
{code}
Your output should be similar to:
{code}
oracle   19789     1 0 19:46 ?        00:00:00 /u01/app/oracle/product/11.2.0/xe/bin/tnslsnr
{code}
Then kill the process, using the appropriate process id, for instance:
{code}
$ sudo kill -9 19789
{code}
h3. 10.b) cannot touch `/var/lock/subsys/listener': No such file or directory
Starting Oracle Net Listener...touch: cannot touch `/var/lock/subsys/listener': No such file or directoryThis error occurs when you run /etc/init.d/oracle-xe configure, but failed the preinstallation step to create the /var//lock/subsys directory as outlined in chapter 8.
h3. 10.c) ORA-00845: MEMORY_TARGET
ORA-00845: MEMORY_TARGET not supported on this system See chapter 7 to enable /dev/shm and verify free space available in /run/shm
h3. 10.d) Apex ADMIN password
According to the Oracle documentation, the password for the INTERNAL and ADMIN Oracle Application Express user accounts is initially the same as the SYS and SYSTEM administrative user accounts. Well, I tried several times without success. To reset the Apex Admin password:
Login as user oracle:
{code}
su - oracle
{code}
Login as SYSDBA and type the following:
{code}
sqlplus / as sysdba
{code}
At the SQL prompt, type the following to be prompted to change the password:
{code}
SQL> @?/apex/apxxepwd.sql
exit
{code}
When done, open your browser and go to http://127.0.0.1:8080/apex
Workspace: Internal
Username: ADMIN
Password: password you set with apxxepwd.sql
I will prompt you to reset the password:
old password: password you set with apxxepwd.sql
new password: final_password
You can also login as the Apex Admin using http://127.0.0.1:8080/apex/apex_admin
h3. 10.e) SYS and SYSTEM password
Use the following commands to reset the SYS and SYSTEM passwords if necessary:
Login as the Oracle user:
{code}
su - oracle
{code}
Login as SYSDBA and type the following at the SQL prompt:
{code}
sqlplus / as sysdba
SQL> alter user sys identified by "password" account unlock;
SQL> alter user system identified by "password" account unlock;
SQL> exit
{code}
h3. 10.f) Uninstall Oracle 11g XE
The following will completely uninstall and remove Oracle 11g XE:
Open a terminal seesion and login as user root:
{code}
sudo su -
{code}
Enter the following:
{code}
/etc/init.d/oracle-xe stop
dpkg --purge oracle-xe
rm -r /u01/app
rm /etc/default/oracle-xe
update-rc.d -f oracle-xe remove
update-rc.d -f oracle-mount remove
update-rc.d -f oracle-shm remove
{code}
h3. 10.g) Reconfigure Oracle 11g XE
Type the following commands in a terminal window:
{code}
sudo /etc/init.d/oracle-xe stop
sudo rm /etc/default/oracle-xe
sudo /etc/init.d/oracle-xe configure
{code}
h3. 10.h) Gnome Classic desktop
Ubuntu 11 moved from the Gnome Classic desktop to Unity and removed the "Ubuntu Classic" login option. Unity was designed to make more efficient use of space given a limited screen size and touch screens. If you prefer to use the Gnome Classic desktop, enter the following into a terminal window:
{code}
sudo apt-get install gnome-panel
{code}
To log into the Gnome Classic desktop, select the "Gearwheel" at the login screen and select "Gnome Classic".
h3. 10.i) Unix vi cursor keys
The instructions in this tutorial do not require the use of any text editor. However, if you would like use the backspace and cursor keys in the "vi-editor", the following needs to be installed:
{code}
sudo apt-get install vim
{code}
h3. 10.j) Backup Database
In order to perform an online database backup using the supplied "Backup Database" script, the database needs to run in Archive-Log mode. This can be setup using the following commands:
Login as the Oracle user:
{code}
su - oracle
{code}
Login as SYSDBA and type the following:
{code}
sqlplus / as sysdba
SQL> shutdown immediate
SQL> startup mount
SQL> alter database archivelog;
SQL> alter database open;
SQL> exit
{code}

Excellent Blog. Thank You
Small clarification on Step **6) Oracle Home Directory, ...a) Resize the Root Partition**
Ubuntu 11.10 has Gparted available as a Ubuntu software download, DONT use that while trying the above step, instead download the ISO file from http://sourceforge.net/projects/gparted/files/gparted-live-stable/ gparted-live-0.12.0-5.iso (124.6 MB)
Burn that ISO file on a Blank DVD, reboot the Ubuntu , during startup select Boot from DVD Option if not already selected. this will take to Boot Menu Options of Gparted Live then select the first menu option, and this allows to do further action such as Re-sizing .
and once you have chosen and executed step a) . do NOT run step b) also that is "Setup External Storage"
I hope this minor clarification can avoid some confusion

Failure to build LabVIEW application on Linux using "Shared library"

In order to create a LabVIEW application on linux without an X display, I complied the LabVIEW VI using the Linux Shared Library. I did this by right clicking on Build Specification and selecting New >> Shared Library, and in the Advanced section, checking the box labeled Use embedded version of run-time engine. At the end of the build process, a message came up informing that the build was unsuccessful, with the following message:
"Error 127 occurred at System Exec: sh: gcc: command not found
The error code is undefined. No one has provided a description for this code, or you might have wired a number that is not an error code to the error code input."
I had no compling the LabVIEW VI in the normal fashion, so am confused about what the problem is.
Solved!
Go to Solution.

Hi Julian,
gcc is a C and C++ compiler on Linux. An easy way to check if it is installed is to open a terminal and type "gcc", if the command is recognized then the package is already installed and the problem must lie elsewhere. If this distrobution of Linux has a package manager included then it should be displayed in there as well. If not then it could point to it being not installed or some dependency is missing making it not accessible from the command line. Here is a link that should hopefully step you through installing gcc with Redhat: http://www.cyberciti.biz/faq/centos-linux-install-gcc-c-c-compiler/ .

Labview support for ISO 8859-5

HI,
does Labview support ISO 8859-5 character sets?
If yes, then how do i change the default character set in Labview from ASCII to ISO 8859-5?
If no, then which is the simplest way to display russian characters in Labview 6.1 (Labview 6.1 on SuSE LINUX)
Thanks and Regards,
Pavitra

Hi Pavitra,
There is a very easy way to do that in Windows. Start>Settings>Regional and Language Options. Make sure Russian is included as an input language language on the language tab, as well as on the advanced tab where you can specify the language for non-unicode programs.
I have attached a screenshot that demonstrates cyrillic fonts in LabVIEW. The example is done with Bulgarian font, but it should work the same way with Russian. As you can see I have also specified Arial CYR as my font for the front panel and the block diagram.
Try to use the same logic for a Linux system.
Hope that helps!

Gentoo Linux and Microsoft Failover Clusters / Hyper-V

Hello,
Hoping there are a few people on the boards familiar with running Gentoo Linux guests under Microsoft FailOver Cluster / Hyper-V hosts.
I have four Gentoo Linux guest VMs (running kernel 3.12.21-r1) running under the Microsoft Failover Cluster system with Hyper-V as the host. All of the Hyper-V drivers are built into the kernel (including the utilities and balloon drivers) and generally they
run without issue.
For several months now, however, I have been having strange issues with them. Essentially they stop responding to network requests after random intervals. However, these intervals aren't a few minutes or hours from each other; more like days or even weeks before
one of them will stop responding on the network side.
The funny thing is that the VMs themselves on the console side still responds. However, if I issue a reboot command on the externally non-responsive VM, the system will eventually get to a stage where all of the services are stopped and then hangs right after
the "mounting remaining system ro" line (or something like that).
The Failover Cluster Manager then reports that the system is "Stopping" but the system never reboots.
I have to completely restart the HOST system so that either (A) the VM in question transfers to another host and starts responding again or (B) when the HOST comes back up I can work with the VM again.
This *ONLY* happens on the Gentoo Linux guest VMs and not my Windows VMs.
Wondering if anyone has hints on this.
Thank you for your time.
Regards, Christopher K.

Hi ckoeber,
Hyper-V has support most of Linux distribution but not all because it’s have so many distribution, until now the Gentoo Linux not in the support list, you can refer the following

Labview code for closing the command window

Hi,
This is naveen.Actually we are using 3rd paty test software for our mobile hardware testing which creates an DOS or Command window after execution.We have automated to execute this software using labview.the problem we facing is that we couldn't run the test software unless we close or kill the dos window opened in the previous run.So i like to know whether you have any labview code for closing or killing the DOS window ,i request you help me in this regard.

Localepurge for arch linux

I just seeked for some thing to clean unused locales from my system and while I used gentoo I used localepurge, so I realize update this script for Arch linux
# unpac this package to your /usr/local (it will make sbin/localepurge and share/localepurge/*)
robertek.no-ip.org/files/localepurge/localepurge.tar.bz2
#copy this file to /etc/locale.nopurge (or wherever else but than you must edit /usr/local/sbin/localepurge)
robertek.no-ip.org/files/localepurge/locale.nopurge
!!!! Before run edit locale.nopurge file and write there your locales you dont want to delete !!!!!
Than if you are pretty sure that you edit correct locales just add "#" before NEEDSCONFIGFIRST
than you can run localepurge (/usr/local/sbin/localepurge if you dont have /usr/local/sbin in your PATH)
!!! BE CAREFULL THERE IS NO WARANTY FOR THIS SCRIPT AND DONT BLAME ME FOR CORRUPTING YOUR SYSTEM !!!! (anyone can just scroll the script and look if it is correct by you look)
For me it work great an I just delete more than 100MB of mess.
Feel free to make a package out of it I will be pleased (and please share).

Using MathScript in LabVIEW eval for Mac

Our university has been slow in getting the LabVIEW 2010 site licensed copy, so we have been forced to use LabVIEW 2010 eval for mac to work with some externally sourced 2010 code that we had to rewrite.
Recently, I requested and received a copy of the free MathScript module for Mac/Linux (2010). Unlike the experience of a NI engineer with 2009 eval, it installed cleanly with LabVIEW eval 2010. However, the MathScript VI does not appear to available in the palette. Restarting LabVIEW does not seem to make a difference.
In case this is an eval version / installer bug, it would make sense to wait for our site license to arrive. However, the site license will probably be available after the holidays and I do not want these two weeks wasted in waiting by the students.
Any ideas ?

Sorry, I don't have any Mac experience, but if you have access to a virtual windows machine (e.g. parallels desktop) you could just use the windows evaluation version instead.

OCS on Gentoo Linux?

Hello All,
Did anybody try to install OCS on Gentoo Linux? What is your experience about it?
Yes, I know, RH AS is the right OS.
Some people likes make things not in right way. And those guys move World. ;)

I am thinking about trying the same thing. I have been pulling my hair out for the last month trying to get the Singlebox Install running on a RedHat 7.3 server. The documentation on this product is deplorable, not to mention that RedHat is the absolute worst linux distribution I have ever seen. I now know why I dropped it in favor of SuSE at version 5.0 and why I dropped RPM based SuSE for Gentoo at version 7.2.
Why does Oracle certify their software for the lousiest most proprietary linux distros out there? The support contracts from the companies are great, if you want to go that route, but if I wanted to go that route I would pay all of the money and sacrifice all of the performance and go with Windows.
Corporations are ruining linux by embracing it and not understanding the fundamental ideologies that went into creating it, with the exception of IBM. A community help system where people are willing to help you as long as you're willing to a) ask for help, and b) work to try and find the answer before you ask. I dont want to pay for support, I dont want it for free either, I'm willing to work for it.
I am currently working on reverse engineering the package versions and dependancies of SuSE Enterprise Server 8.0 and I am going to build a custom Gentoo box with those packages. If you are interested in my findings and results let me know and I'd be glad to share with you and the rest of the world, unlike Oracle, RedHat and SuSE.
I'm also thinking about talking to the Gentoo developers and forums to find out if they're interested in hosting a forked branch of the distro, because the package dependancies are pretty specific from what I can tell.
I think it's great that world class software companies such as Oracle are embracing linux and supporting it fully, but they need to move away from the linux distributions that are poisioning the open-source philosophy. Oracle should, in my opinion compile on a more vendor neutral distribution such as debian, gentoo or slackware. Then release the package requirements and let the end user decide which distribution they want to use, not the other way around.
