Oracle Database Starting Error - ORA-00845: MEMORY_TARGET not supported on this system [SOLVED]

2013-09-18T03:20:00.000-07:00

Guys

I got this error when I start oracle instance.

"ORA-00845: MEMORY_TARGET not supported on this system"

Some of the forum said about of tmpfs size which is mounted on /dev/shm.
Then I saw this post.
So I suspected it isn't enough space of share memory.

I checked with "df" command.

That space is currently amount mounted on /dev/shm. So I think that 5.9G isn't enough.
It's need to set a mount which over 5.9G manually.

Then I changed at /etc/fstab as below. (changed "default" to "size=6g" )

Then, have restarted the host and checked the size with "df" again.

Then , try to start the instance again.

#sqlplus / as sysdba
SQL>startup

This time nothing error occur. :)

Oracle Listener Can't Start Error - Linux Error: 29: Illegal seek [SOLVED]

2013-09-17T23:56:00.000-07:00

Hi Guys,

I'm want to share how to solve to Oracle Listener Error "Linux Error: 29: Illegal seek" .

This Error occur when starting listener on linux box.

This Listener must support to the remote connection also.
On the First, I checked on the /etc/hosts file.

If I configured to /etc/hosts file with " 127.0.0.1 localhost localhost.localdomain" (only one-line), I can start oracle listener as well.
But If I put other hostname for remote connection at /etc/hosts like "192.168.1.2 localhost localhost.localdomain" , I can't start listener anymore and got above error.

I tried a few changes on /etc/hosts. But It isn't working.
Then, I read at the oracle wiki about of listener. I decided to change the name at the listener.ora file.

So go to the listener file location .

I changed as putting IP (192.168.1.2) at HOST.

Then, save the file and start the listener.

#lsnrctl start

It's working without any error. :)

VMware Error (Solved) : The attempted operation cannot be performed in the current state (Powered Off)

2013-08-07T02:28:00.001-07:00

Hi Guys,

You may be face this error on ESXi server after deploy the vm image onto ESXi.

" The attempted operation cannot be performed in the current state (Powered Off)"

After convert the vm, you will try power-on to the vm image. But vm can't boot up and it's only show above error at the console. And you can't power-off to that vm image also. This may occur relatively snapshot of vm image.

Here I will show how to solve this error.

First, you need to power-off the vm, but you can't power off from vSphere or vCenter.
So login to the ESXi server via ssh.

And use the "esxtop" and need to find out the WID of that vm's process and kill it.
#esxtop
By default, esxtop won't show the WID, you need to enable in the feild order.
So Press "f"
and choose the WID feild and press "Enter".

Now it's showing WID at the esxtop field. And record the WID of your vm name.

And To kill the process, press "k" and put the WID of your vm then press enter . Now you can quit from the esxtop, Press "q". Check at the vSphere, you will be see your vm is already power off.

Now you need to go VM folder location, So browse the datastore, and find your vm image folder and browse it.

There, you will be found "xxxxx.vmsd" file and delete it.

Now you can power-on the vm image again, It will up successfully without error. :)

FUNNY Linux COMMANDs ..

2013-07-04T02:01:00.002-07:00

This is the Just Share What I founded a post of Funny Linux Commands ... :)

1. Command: sl (Steam Locomotive)

You might be aware of command ‘ls‘ the list command and use it frequently to view the contents of a folder but because of miss-typing sometimes you would result in ‘sl‘, how about getting a little fun in terminal and not “command not found“.

Install sl

root@tecmint:~# apt-get install sl 		(In Debian like OS)
root@tecmint:~# yum -y install sl 		(In Red Hat like OS)

Output

root@tecmint:~# sl

sl command

This command works even when you type ‘LS‘ and not ‘ls‘.

2. Command: telnet

No! No!! it is not as much complex as it seems. You would be familiar with telnet. Telnet is a text-oriented bidirectional network protocol over network. Here is nothing to be installed. What you should have is a Linux box and a working Internet.

root@tecmint:~# telnet towel.blinkenlights.nl

telnet command

3. Command: fortune

what about getting your random fortune, sometimes funny in terminal.

Install fortune

root@tecmint:~# apt-get install fortune 	(for aptitude based system)
root@tecmint:~# yum install fortune 		(for yum based system)

root@tecmint:~# fortune

You're not my type.  For that matter, you're not even my species!!!
Future looks spotty.  You will spill soup in late evening.
You worry too much about your job.  Stop it.  You are not paid enough to worry.
Your love life will be... interesting.

6. Command: script

OK fine this is not a command and a script but it is nice.

root@tecmint:~# for i in {1..12}; do for j in $(seq 1 $i); do echo -ne $iÃ—$j=$((i*j))\\t;done; echo;done 

1Ã—1=1

7. Command: Cowsay

An ASCII cow in terminal that will say what ever you want.

Install Cowsay

root@tecmint:~# apt-get install cowsay 		(for Debian based OS)
root@tecmint:~# yum install cowsay		(for Red Hat based OS)

Output

root@tecmint:~# cowsay I Love nix 

 ____________
< I Love nix >
 ------------
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||

How about pipelineing ‘fortune command‘, described above with cowsay?

root@tecmint:~# fortune | cowsay 

 _________________________________________
/ Q: How many Oregonians does it take to  \
| screw in a light bulb? A: Three. One to |
| screw in the light bulb and two to fend |
| off all those                           |

 -----------------------------------------
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||

Note: ‘|‘ is called pipeline instruction and it is used where the output of one command needs to be the input of another command. In the above example the output of ‘fortune‘ command acts as an input of ‘cowsay‘ command. This pipeline instruction is frequently used in scripting and programming.
xcowsay is a graphical program which response similar to cowsay but in a graphical manner, hence it is X of cowsay.

apt-get insatll xcowsay
yum install xcowsay

Output

root@tecmint:~# xcowsay I Love nix

xcowsay command

cowthink is another command just run “cowthink Linux is sooo funny” and see the difference in output of cowsay and cowthink.

apt-get insatll cowthink
yum install cowthink

Output

root@tecmint:~# cowthink ....Linux is sooo funny
 _________________________
( ....Linux is sooo funny )
 -------------------------
        o   ^__^
         o  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||

8. Command: yes

It is funny but useful as well, specially in scripts and for System Administrators where an automated predefined response can be passed to terminal or generated.

root@tecmint:~# yes I Love Linux

I Love Linux
I Love Linux
I Love Linux
I Love Linux
I Love Linux
I Love Linux
I Love Linux
I Love Linux
I Love Linux
I Love Linux
I Love Linux
I Love Linux

Note: (Till you interrupt i.e ctrl+c).

9. Command: toilet

what? Are u kidding, huhh no! Definitely not, but for sure this command name itself is too funny, and I don’t know from where this command gets it’s name.

Install toilet

root@tecmint:~# apt-get install toilet 
root@tecmint:~# yum install toilet

Output

root@tecmint:~# toilet tecmint 

mmmmmmm                        "             m                               
   #     mmm    mmm   mmmmm  mmm    m mm   mm#mm          mmm    mmm   mmmmm 
   #    #"  #  #"  "  # # #    #    #"  #    #           #"  "  #" "#  # # # 
   #    #""""  #      # # #    #    #   #    #           #      #   #  # # # 
   #    "#mm"  "#mm"  # # #  mm#mm  #   #    "mm    #    "#mm"  "#m#"  # # #

It even offers some kind of color and fonts style.

root@tecmint:~# toilet -f mono12 -F metal Tecmint.com

toilet command

Note: Figlet is another command that more or less provide such kind of effect in terminal.

10. Command: cmatrix

You might have seen Hollywood movie ‘matrix‘ and would be fascinated with power, Neo was provided with, to see anything and everything in matrix or you might think of an animation that looks alike Hacker‘s desktop.

Install cmatrix

root@tecmint:~# apt-get install cmatrix
root@tecmint:~# yum install cmatrix

Output

root@tecmint:~# cmatrix

cmatrix command

11. Command: oneko

OK so you believe that mouse pointer of Linux is the same silly black/white pointer where no animation lies then I fear you could be wrong. “oneko“ is a package that will attach a “Jerry“ with you mouse pointer and moves along with you pointer.

Install cmatrix

root@tecmint:~# apt-get install oneko
root@tecmint:~# yum install oneko

Output

root@tecmint:~# oneko

oneko command

Note: Once you close the terminal from which oneko was run, jerry will disappear, nor will start at start-up. You can add the application to start up and continue enjoying.

12. Fork Bomb

This is a very nasty piece of code. Run this at your own risk. This actually is a fork bomb which exponentially multiplies itself till all the system resource is utilized and the system hangs. (To check the power of above code you should try it once, but all at your own risk, close and save all other programs and file before running fork bomb).

root@tecmint:~#  ){  :& }:

13. Command: while

The below “while” command is a script which provides you with colored date and file till you interrupt (ctrl + c). Just copy and paste the below code in terminal.

root@tecmint:~# while true; do echo "$(date '+%D %T' | toilet -f term -F border --gay)"; sleep 1; done

Linux while command

Note: The above script when modified with following command, will gives similar output but with a little difference, check it in your terminal.

root@tecmint:~# while true; do clear; echo "$(date '+%D %T' | toilet -f term -F border --gay)"; sleep 1; done

14. Command: espeak

Just Turn the Knob of your multimedia speaker to full before pasting this command in your terminal and let us know how you felt listening the god’s voice.

Install espeak

root@tecmint:~# apt-get install espeak
root@tecmint:~# yum install espeak

Output

root@tecmint:~# espeak "Tecmint is a very good website dedicated to Foss Community"

15. Command: aafire

How about fire in your terminal. Just type “aafire” in the terminal, without quotes and see the magic. Press any key to interrupt the program.

Install aafire

root@tecmint:~# apt-get install libaa-bin

Output

root@tecmint:~# aafire

First install “apt-get insatll bb” and then, type “bb” in terminal and see what happens.

root@tecmint:~# bb

bb command

17. Command: url

root@tecmint:~# url -u YourUsername:YourPassword -d status="Your status message" http://twitter.com/statuses/update.xml

18. ASCIIquarium

How it will be to get an aquarium in terminal.

root@tecmint:~# tar -zxvf Term-Animation-2.4.tar.gz
root@tecmint:~# cd Term-Animation-2.4/
root@tecmint:~# perl Makefile.PL &&  make &&   make test
root@tecmint:~# make install

Install ASCIIquarium

Now Download and Install ASCIIquarium.

root@tecmint:~# cd /tmp
root@tecmint:~# wget http://www.robobunny.com/projects/asciiquarium/asciiquarium.tar.gz
root@tecmint:~# tar -zxvf asciiquarium.tar.gz
root@tecmint:~# cd asciiquarium_1.1/
root@tecmint:~# cp asciiquarium /usr/local/bin
root@tecmint:~# chmod 0755 /usr/local/bin/asciiquarium

And finally run “asciiquarium” or “/usr/local/bin/asciiquarium“ in terminal without quotes and be a part of magic that will be taking place in front of your eyes.

root@tecmint:~# asciiquarium

aquarium command

19. Command: funny manpages

Guys.. I am not a DBA. I am just a SA. But SA role is related with Database environment also. And I think that every SA should know about basic of Database as like how to Start/Shutdown the database service properly.

Let's say.. you need to shutdown the Oracle Database server machine for your maintainance of hardware or other purpose. If you are going to shutdown the server before shutdown the database , Man .. It will be like that you find the risk by yourself and call phone to DBA .. :)

Ok .. Here is the start and shutdown process of the orcale database which is running on solaris .

Startup
If you are already login to solaris terminal with root , change to orcale user

#su - oracle

Enter the following command to start SQL Command Line

#sqlplus

It will ask to type user name type " / as sysdba"

#Enter user-name: / as sysdba
(note: you can use only one command to login SQL command line "#sqlplus / as sysdba" )

To start the database , type follow command : "STARTUP"

SQL>STARTUP

And type "exit" for leave the sql command line.

SQL>exit

Then, Start the Oracle listener : (If Orcale Database is for remote clients, you will need this step)

#lsnrctl start
Shutdown
If you are already login to solaris terminal with root , change to orcale user

#su - oracle

Enter the following command to start SQL Command Line

#sqlplus

It will ask to type user name type " / as sysdba"

#Enter user-name: / as sysdba

To shutdown the database , type follow command : "SHUTDOWN IMMEDIATE"

SQL> SHUTDOWN IMMEDIATE

And type "exit" for leave the sql command line.

SQL>exit

Then, Stop the Oracle listener : (If you Orcale Database is for remote clients, you will need this step)

#lsnrctl stop

OK now switch back to root user and process to shutdown the solaris OS

#shutdown -y -g0 -i5

Mouse Without Border ...

2013-01-22T20:17:00.000-08:00

Guys..

Ok Let say, You are a busy guy, you have to control different OS with different monitors, which are on your small desk. If you are using one mouse and one keyboard for each OS, Do you think you will be convenience on your small desk? (that's my reson :P )

Here let me introduce two product that allow you to control so many computer by one pair of keyboard and mouse.....

1) Microsoft Garage Mouse Without Borders

"Mouse without Borders is a product that makes you the captain of your computer fleet by allowing you to control up to four computers from a single mouse and keyboard. This means that with Mouse without Borders you can copy text or drag and drop files across computers."

This will allow you to control between various of Microsoft OS Windows 7, Windows 8, Windows Server 2003, Windows Server 2008, Windows Server 2012, Windows Vista, Windows XP. But This is support between only Microsoft OS Platforms.

you can download freely @ below link..

http://www.microsoft.com/en-us/download/details.aspx?id=35460

2) Synergy

"Synergy lets you easily share your mouse and keyboard between multiple computers on your desk, and it's Free and Open Source. Just move your mouse off the edge of one computer's screen on to another. You can even share all of your clipboards. All you need is a network connection. Synergy is cross-platform (works on Windows, Mac OS X and Linux)."

This is a alternative way of Microsoft Mouse Without Border But this will allow you to control between Microsoft OS, Linux or Mac.

http://synergy-foss.org/

Note: I want to recommend "Microsoft Mouse Without Border" if your OS are various of Microsoft OS because it's allow you to copy, drag and drop a file via this product.

Solaris 10 Internet not working problem with Web Browser

2013-01-20T23:04:00.000-08:00

Solaris 10 Internet not working problem with Web Browser

Problem is here ..

I configured the static IP on Solaris 10. And I tried to browse the website on browser of Solaris 10. But I can't browse any website on the browser.

So Tested the "nslookup" on terminal , It's ok.

Ping to Google IP, It's return back "alive".

So I tried search on the google/forum for this problem.

"This is what i founded and that is the perfect answer for this problem."

Yes , There have two things that you may be forget when you setting up the IP configuration on Solaris .

1) Must be sure to add nameserver on /etc/resolv.conf

2) And Most of the people are forget to put the entry called "dns" at behind of "hosts" line in the /etc/nsswitch.conf . I am also no idea to do this before :P

Ok now you may be restart the network service or reboot the system.

#svcadm restart network/physical

Configuration of Static IP on Solaris 10

2013-01-18T02:14:00.000-08:00

Configuring the static ip on Solaris 10 is different with the other linux. You have to configure a few files.

Firstly you must know your interface name of your solaris. You can get your interface name with following command.

#dladm show-link

If your solaris is configured with the DHCP, you must delete file /etc/dhcp.interface (/etc/dhcp.e1000g0). Now you have to configure with below files :

/etc/hosts
/etc/hostname.interface
/etc/nodename
/etc/inet/hosts
/etc/inet/ipnodes
/etc/defaultrouter

Add the IP and hostname at /etc/hosts

Add IP and Netmask at /etc/hostname.interface (/etc/hostname.e1000g0)

Add the hostname at /etc/nodename , If nodename file isn't available at /etc by the default, create byself.

/etc/inet/hosts and /etc/inet/ipnodes will updated automatically if you updated your hostname on /etc/hosts. If not, add the same entries as /etc/hosts.

Add default gateway ip at /etc/defaultrouter, If defaultrouter file isn't available at /etc by the default, create byself.

Now, restart the Network service using following command or reboot the server for the changes to take effect.

# svcadm restart network/physical

NIC Teaming On VMware ESXi

2013-01-03T06:33:00.003-08:00

NIC Teaming On VMware ESXi

This will show you to how to create a teaming with 2 nics on VMware ESXi 5.0 .

Why we need the nic teaming for a virtual environment?

" A NIC team can share the load of traffic between physical and virtual networks among some or all of its members, as well as provide passive failover in the event of a hardware failure or network outage. " By kb.vmware

Ok Let's start..

1) Connect to your ESXi box with the vSphere Client..

2) Choose the "Configuration"

3) Choose "Networking" from the Hardware Panal

4) Click "Add Networking"

5) Choose "Virtual Machine" and click "Next"

6) Choose "Create a vSphere Standard switch" and tip on the 2 nics which are you want to prefer to be a teaming then click the "Next"

7) Click "Next"

8) Click "Finish"

9) Click the "Properities" of created vSwitch

10) Choose "VM Network" and Click the "Edit"

11) Click the "NIC Teaming" tab.

12) Tip on the "Load Balancing" and choose the "Route based on the originating virtual port ID" then click "Ok".

13) Click "Close"

Now Nic teaming is finish !! We can define the TCP/IP information by adding "VM Kernal" on that vSwitch..

libc.so.1: version `SUNW_1.22.7' not found (Fixed)

2012-12-10T20:32:00.003-08:00

I faced this problem when I'm installing rsync on Oracle Solaris 10 9/10 s10x_u9wos_14a X86. Even installed the all of the dependencies packages of rsync, errors is still there. And I tried to get solution from some of the forum but they said this is the major Bug and all are advised to patching or upgrade to Oracle Solaris 10 8/11 s10x_u10wos_17b X86. This error made me sick a few days :)
But Finally I fixed the problem without patching and upgrading.

Solution :
Don't install the "rsync-3.0.9-sol10-x86-local.gz" and Download the " rsync-3.0.9.tar.gz" and compile the package yourself then install it.

Here is the step by step how I fixed the problem >>>>

Requirements Packages.

rsync-3.0.9.tar.gz
popt-1.16-sol10-x86-local.gz
libiconv-1.14-sol10-x86-local.gz
libintl-3.4.0-sol10-x86-local.gz
libgcc-3.3-sol10-intel-local.gz
gcc-3.3.2-sol10-intel-local.gz
make-3.82-sol10-x86-local.gz

All of the packages can be download at www.sunfreeware.com

Installations Dependencies

#gunzip popt-1.16-sol10-x86-local.gz
#pkgadd -G -d popt-1.16-sol10-x86-local
-------------------
libiconv-1.14-sol10-x86-local.gz

#gunzip libiconv-1.14-sol10-x86-local.gz
#pkgadd -G -d libiconv-1.14-sol10-x86-local

#gunzip gcc-3.3.2-sol10-intel-local.gz
#pkgadd -G -d gcc-3.3.2-sol10-intel-local
-------------------

After Installation, Check Library path

#ldd /usr/local/bin/gcc
        libc.so.1 =>     /lib/libc.so.1
        libm.so.2 =>     /lib/libm.so.2

#which gcc
no gcc in /usr/sbin /usr/bin   <<<------If Not Found

If not found, Add below two line in the /etc/profile with editing command "#gedit /etc/profile" or "vi /etc/profile"
PATH="$PATH:$HOME/bin:/usr/sbin:/usr/bin:/usr/local/bin:/lib/amd64:/lib:/usr/local/lib:"
export PATH

Recheck Library gcc

# which gcc
/usr/local/bin/gcc

Installation Make and Rsync

make-3.82-sol10-x86-local.gz

#gunzip make-3.82-sol10-x86-local.gz
#pkgadd -G -d make-3.82-sol10-x86-local
-------------------

#gunzip rsync-3.0.9.tar.gz
#tar xvf rsync-3.0.9.tar
#cd rsync-3.0.9.tar
#./configure
#make <<<<---------------- If Face with error check with exception step
#make install

Exception Step
Go to under below folder and execute mkheaders
#cd /usr/local/lib/gcc-lib(or)gcc/i386-pc-solaris2.10/3.3.2/install-tools
Execute the "mkheaders" file
#./mkheaders

Go back to under rsync folder and follow below step
#make clean
#./configure
#make
#make install

Checking installation of Rsync

# which rsync
/usr/local/bin/rsync

#rsync -v
rsync version 3.0.9 protocol version 30
Copyright (C) 1996-2011 by Andrew Tridgell, Wayne Davison, and others.

# rsync -v <<<---------- If Face with error, follow step
ld.so.1: rsync: fatal: libiconv.so.2: open failed: No such file or directory
Killed

Check libiconv.so.2 path and copy into /lib folder

# pkgchk -LP libiconv |grep libiconv.so.2
/usr/local/lib/libiconv.so=libiconv.so.2.5.1 s none SMCliconv
/usr/local/lib/libiconv.so.2=libiconv.so.2.5.1 s none SMCliconv
/usr/local/lib/libiconv.so.2.5.1 f none 0755 bin bin 981967 8854 1334657763 SMClico

Copy the /usr/local/lib/libicopvs /usr/lib/libc.so.1nv.so.2 file under /lib folder

# cp /usr/local/lib/libiconv.so.2 /lib

Now you can successfully installed the rsync and ready to use !!!

You can check "SUNW_1.22.7" is still missing but now rsync is working well.. :)

# pvs /usr/lib/libc.so.1
libc.so.1;
        SUNW_1.23;
        SUNW_1.22.6;
        SUNW_1.22.5;
        SUNW_1.22.4;

So If you get this error when you are installing the other packages on Oracle Solaris 10 9/10 s10x_u9wos_14a X86, you should compile the package by yourself and install it. And don't forget to install the other dependencies packages. For me, "wget" installation also fixed with manually compiling.

Have a Nice Day .. :)

Useful Tricks and Command of Linux !!

2012-09-20T19:45:00.003-07:00

Hi Guys,

I founded some of the shortcut, command and tricks for linux. So I wanna share with you. Check it out below..

1.) Ctrl+U and Ctrl+Y.
Do you know that moment when you’re typing a long command, and then suddenly realize you need to execute something else first? Especially when working over an SSH connection, when you can’t easily open a second terminal on the same machine, this can be very annoying. Solution: ensure your cursor is at the end of your current command (shortcut: Ctrl+E), press Ctrl+U to get a clean line, type the other command you need to execute first, execute it, then press Ctrl+Y and voila! Your long command is back on the line. No mouse needed for copying, just quick hotkeys.

2.) Ctrl+R.
Speaking of long commands: when you need a previously used command again but don’t want to retype it because it’s long or complex, there’s a good chance it’s stored in your history file. The quickest way to retrieve and execute it is to press Ctrl+R and type a few characters that are part of your command. For example:

for pid in $(pidof plugin-container); do file /proc/”$pid”/fd/* |
fgrep /tmp/Flash | cut -d: -f1 | xargs mplayer; done

Now that’s a command that I wouldn’t like to type every time I use it. It’s a one-liner to play the temporary media files Flash secretly stores when you play, for example, a YouTube movie. When I want to execute this monster, I only type the following:
Ctrl+R
“pidof”
Enter
The stuff between quotes is literally typed, as in I press p, then i, and so on. The reason this works is that I almost never use the pidof command except in this one-liner, so the most recent command executed that contains “pidof” is almost always the right one. However, suppose I did recently execute a different command containing “pidof”. By repeatedly pressing Ctrl+R after typing “pidof” but before pressing Enter, I can cycle through the list of commands until I hit the one I meant to execute, and then press Enter. And, last but not least, you can still edit the command you found using Ctrl+R before hitting Enter; just press the right or left arrow to get out of the history search mode, and edit away!

3.) The screen command.
When working over an ssh connection, commands that take long to execute can seriously get in your way. You have to keep the connection open to allow the command to complete, which means that you can’t turn off your computer, and you can’t execute a different command without opening a second ssh connection or (temporarily) terminating the running command. Both annoyances melt away when you use screen.
The screen command allows you to run multiple terminal sessions inside a single terminal session, and manage the multiple sessions using hotkeys. Try it! Just execute “screen” in your terminal (install it first if necessary) and see an empty terminal opening. Now execute the command “sleep 9999″. This will take quite long and block your terminal. However, if you press Ctrl+A, let go of the keys, and then press C, you will get a fresh new terminal ready to take commands. The sleep command on the other terminal keeps running without being interrupted. To cycle between the two open terminals, use Ctrl+A N for next and Ctrl+A P for previous (remember to let go of all keys after pressing Ctrl+A). Finally, to shut down screen without interrupting the commands that are running, press Ctrl+A D for detach. You will return to your original terminal, and if it’s an ssh session, you can exit it without interrupting the commands running in screen. To get back to the screen terminals you opened before, execute “screen -R” for reattach. To exit a screen session, just exit all terminals in it as you would normally exit terminals (Ctrl+D).
For more information about screen, read its man page by executing “man screen”. It’s a very powerful tool that even allows multiple people to use a single terminal at the same time!

4.) The xargs command.
Whenever you want to execute a command on multiple files, or for every line of a certain file, xargs is the first tool to look at. Here’s an example:

find . -iname ‘*.php’ -print0 | xargs -0 svn add

Anyone who has ever worked with a version control system like svn probably knows the annoyance of having to svn add every newly created code file after a few hours of editing. This command does it for you in an instant. How does it work?

“find . -iname *.php -print0″ prints all files in the current directory (“.”) or its subdirectories that end in .php (case-insensitive) and separates them by null characters (“-print0″). The null character is never used in filenames, while a newline may be, so it is safer to separate by null characters.
“xargs -0 svn add” receives the output of find on its standard input through the pipe (“|”), separates it by null characters (“-0″) and feeds the filenames as arguments to svn, after the “add” argument. It minds the limits the system imposes on the amount and size of command line arguments, and will run svn multiple times as necessary while still invoking it as few times as possible.

To find out more about xargs, read the man page by executing “man xargs”. Using xargs is safer and more versatile than using the -exec option of find. For ultimate versatility, however, use the slightly less elegant for loop, which is described in the second part of this list.

5.) Using bash as a simple calculator.
Sometimes you need to quickly do a calculation that is too large or too important to do using your head. When you’re working in a graphic environment, you might just fire up kcalc or gcalctool, but tools like that may not always be available or easy to find. Fortunately, you can do basic calculations within bash
itself. For example:

echo $((3*37+12)) # Outputs 123
echo $((2**16-1)) # Two to the power of sixteen minus one; outputs 65535
echo $((103/10)) # Outputs 10, as all these operations are integer
arithmetic
echo $((103%10)) # Outputs 3, which is the remainder of 103 divided by
10

The $((something))-syntax also allows bitwise operations, and as such it interprets the caret (“^”) as a bitwise operator. That’s why “**” is used for “to the power of”. The syntax also supports showing the decimal equivalent of a hexadecimal or octal number. Here’s an example:

echo $((0xdeadbeef)) # Outputs 3735928559
echo $((0127)) # Outputs 87

For more information, read the bash man page using “man bash” and search (using the / key) for “arithmetic evaluation”. If you want to do floating point calculations, you can use bc (might need to install first):

echo ‘scale=12; 2.5*2.5′ | bc # Outputs 6.25
echo ‘scale=12; sqrt(14)’ | bc # Outputs 3.741657386773

Note the setting of the scale variable. Using bc, you can perform floating point operations with any precision you like. The scale variable controls the amount of decimals behind the dot that are calculated. I used 12 here because kcalc uses that amount by default, but you can increase or decrease it as you like. Find out more about what bc can do by executing “man bc”. It even supports more advanced mathematical functions, such as the arctangent or the natural logarithm.

6.) Quoting.
To allow you to write awesome scripts, bash attaches a special meaning to many characters (like * & ; | { ! < [ # and a lot more). Sometimes, however, these characters are not to be interpreted in any special way, but just to be passed unmodified to some command. A commonly used example:

find . -iname '*.conf'

Notice the single quotes around "*.conf". What if I forgot those? Bash would interpret the *.conf as a glob expression and expand it to all files ending in .conf in the current directory. This could prevent find from looking for all .conf files in subdirectories, causing unexpected results. Therefore, it's a good habit to always quote anything that might contain special characters.
Note that only single quotes prevent every character from being interpreted; double quotes still allow bash to interpret some characters. When working with variables, double quotes come in handy to prevent word splitting. This is often used in scripting. An example:

#!/bin/bash
# This script renames a file to lowercase
newname="$(echo -n "$1" | tr '[A-Z]‘ ‘[a-z]‘)”
mv -i “$1″ “$newname”

You can see quite a lot of double quotes in this script, and all of them are necessary to prevent trouble with certain filenames. You see, when a filename contains whitespace, bash splits the name on that whitespace when you leave variables unquoted. Suppose you have a file named “spaced name.txt”, you put it in a variable (“filename=’spaced name.txt’”), and then you try to move it to “unspacedname.txt” by executing “mv $filename unspacedname.txt”. You’ll get the error “mv: target `unspacedname.txt’ is not a directory”. This is because mv gets executed like this: “mv spaced name.txt unspacedname.txt”. In other words, mv will try to move two files, “spaced” and “name.txt” to “unspacedname.txt”, and fail because moving multiple files to a single destination is only allowed when the destination is a directory. Putting double quotes around “$filename” solves this issue.
So you see, quoting is a good habit to prevent your commands and scripts from doing unexpected things. Two final notes: you can’t quote variables using single quotes, because the dollar sign loses its special meaning between single quotes, and if you ever need to use a literal single quote in some command, you can do so by putting it between double quotes. Using \’ between single quotes will not work, because even the backslash it not interpreted between single quotes.

7.) For loops.
Using xargs, you can run a command on a list of files. However, sometimes you’ll want to use more advanced functionality of bash on a list of files. For example, you might want to set up a pipe of commands, like this:

# Count the number of while loops in each of the php files in the
current directory
for file in ./*.php; do echo -n “$file”:\ ; grep ‘while’ “$file” | wc
-l; done

Let me explain what happens there part by part:

“for file in ./*.php”: make a list of all the files ending in “.php” in the current directory, and for each of them, run the following code with the variable “$file” set to the filename.
“do … done”: indicates the beginning and end of the code inside the for loop. Note that both of them have to start on a new line, which is why the semicolons are there. They count for starting a new line.
“echo -n “$file”:\ “: print the filename, followed by a colon and a space, but not a newline (the “-n” option suppresses the default extra newline). The backslash makes sure the space is actually printed and not eaten away by bash.
“grep ‘while’ “$file” | wc -l”: grep reads the file and prints only the lines containing the word “while”. These lines are piped to
“wc -l”, which counts the amount of lines (word count with option lines).

As you can see, you can easily place multiple commands within the for loop; every bit of code between “do” and “done” is executed for every file. Imagine the possibilities, especially when you get to know more of the built-in bash functionality. Read on for an example of that.

8.) String manipulation.
There comes a time in the life of every serious bash user when some string manipulation is needed. For example, you might have a number of photos
of which the filenames start with “DSC”, and you’d like to replace that prefix with something more meaningful, like “Vacation2011″. Using a for loop as it was introduced above, you can do this in a flash (pun intended):

for file in DSC*; do mv “$file” Vacation2011″${file#DSC}”; done

How does this work? The for loop runs for every file in the current directory of which the name begins with “DSC”. For every such file, mv is executed to move the file to “Vacation2011<name of the file with DSC stripped from the front>”. The magic that strips “DSC” happens in “${file#DSC}”, where the “#” indicates that the string after it should be removed from the front of the contents of the variable before it. There also exist operations to strip from the back of the string (useful for removing file extensions), to search and replace in a string and to extract substrings. To learn more about string manipulation, visit Manipulating
Strings on TLDP.

9.) Dynamic port forwarding.
Sometimes you need to access a website that’s only accessible from computers inside a certain network. Or, the other way around, sometimes you are in a certain network and you need unobstructed access to the internet, but some hyperactive firewall is in the way. If you have ssh access to a computer that does have the internet access you need, you can use it as an anonymous tunneling proxy without any additional tools. Just add the following option when you ssh into the server:

ssh -D <port number> user@remotehost

The -D option tells ssh to set up a dynamic port forward on local port <port number>. I like to use port number 1337, but almost any port between 1024 and 65535 will do. When you’ve logged in on the remote server, you can configure your browser to use localhost with the port number you specified earlier as a SOCKS proxy (SOCKS versions 4 and 5 are both supported). This setting is usually found in the same place as the other options for using a web
proxy. In Firefox, look under Preferences => Advanced => Network => Configure how Firefox connects to the Internet. Once you’re browsing over this SOCKS proxy, it will appear to the web as if the host you sshed into is browsing.

10.) Process substitution.
Ever wanted to diff the outputs of two commands quickly? Of course, you could redirect the output to a temporary file for both of them, and diff those files, like this:

find /etc | sort > local_etc_files
find /mnt/remote/etc | sort > remote_etc_files
diff local_etc_files remote_etc_files
rm local_etc_files remote_etc_files

This would tell you the differences between which files are in /etc on the local computer and a remote one. It takes four lines, however. Using process substitution, we can do this is just a single line:

diff <(find /etc | sort) <(find /mnt/remote/etc | sort)

What’s that <(…) syntax? It means “run the command inside it, connect the output to a temporary pipe file and give that as an argument”. To understand this more thoroughly, try running this:

echo <(echo test)

Instead of printing “test”, this will print something like “/dev/fd/63″. You see now that the <(…) part is actually replaced by a file. This file is a stream from which the output of the command inside <(…) can be read, like this:

cat <(echo test)

Now this does print “test”! Bash redirects the output of “echo test” to /dev/fd/<something>, gives the path of that file to cat, and cat reads the output of echo from that file. The shortened diff command above does the same, only for two slightly more complicated commands. This technique can be applied in any place where a temporary file is needed, but it does have a limitation. The temporary file can only be read once before it disappears. There’s no use in saving the name of the temporary file. If you need multiple accesses to the output of a program, use an old-fashioned temporary file or see if you can use pipes instead.

Bonus!
Thought you would only get 10 tricks? Wrong ! There’s one more thing I just can’t help but share with you. If you ever (are forced to) work with Windows, you don’t have to miss out on all of these tricks. You can ssh to remote hosts using PuTTY, which is a portable program, and copy files to and from servers with SSH access using WinSCP, which also has a portable version. And, to take it even further, you can use bash on Windows by installing Cygwin!

Linux System မွာ Swap Space လိုအပ္လာရင္

2012-03-06T02:51:00.001-08:00

Linux OS တခုေပၚမွာ Database Engine ေတြလိုမ်ိဳး Run ရျပီဆိုရင္ RAM or SWAP Space မ်ားမ်ားလိုအပ္တဲ့ Problem ေတြ ေတြ႕ေကာင္းေတြ႕ပါလိမ့္မယ္.. ဥပမာ တခ်ိဳ႕ Database Engine ကို Installation လုပ္ရင္ Installation ကသက္မွတ္ထားတဲ့ RAM or SWAP space အက်ယ္အဝန္း မရွိရင္ဘယ္လိုမွတင္လို႕ မရပါဘူး... အဲဒီလိုမ်ိဳး အခါမွာ RAM ကိုလဲ တိုးဖို႕ မလြယ္ဘူး ဆိုရင္ swap space ကိုတိုးေပးဖို႕လိုအပ္ လာပါျပီ...

အရင္ဆုံး လက္ရွိ System က Swap ကို ဘယ္ေလာက္ သံုးထားလဲ ဆိုတာကို ေအာက္က Command နဲ႕ၾကည့္ပါမယ္

#swapon -s
OR
#free -k

Note : ဒီပံုမွာေတာ့ System က Swap Space ကိုဘယ္ေလာက္သံုးေနတယ္ဆိုတာ “Used” ဆိုတဲ့ေအာက္မွာ ျပမွာပါ

ဒီမွာေတာ့ /dev/hdc5 ဆိုတဲ့ partition ေပၚမွာပဲ file တခု ပံုစံ လုပ္ျပီ အဒီေပၚမွာ swap space သတ္မွတ္တာကို ျပပါမယ္.. Swap Space File ကို File System ရဲ့ကိုၾကိဳက္တဲ့ ေနရာမွာ ျပဳလုပ္ႏိုင္ပါတယ္..အဲဒီေတာ့ အလြယ္တကူ / (root) ေအာက္မွာပဲ လုပ္ပါမယ္..

dd commandနဲ႕ 1GB ရွိတဲ့ file တခုကို /(root) ေအာက္မွာ ေအာက္ပါ အတိုင္း လုပ္လိုက္ပါမယ္..
Note : Linux Master ေတြ အသီးသီးရဲ့ Recommend ကေတာ့ Swap Space ကို သတ္မွတ္ရင္ ၄ နဲ႕စားလို႕ ျပတ္တဲ့ Amount က အေကာင္းဆုံးပါပဲတဲ့ အဲဒီေတာ့ 1GB ဆိုေတာ့ 1024MB ေပါ့ ၄နဲ႕ စားလို႕ျပတ္ ပါတယ္...

#dd if=/dev/zero of=/additional-swap bs=1M count=1024

အဲဒီ create လုပ္လိုက္တဲ့ /(root) ေအာက္က additional-swap ဆိုတဲ့ fileကို swap အျဖစ္ သတ္မွတ္ပါမယ္..

#mkswap /additional-swap

System ကို Swap အတြက္ Space ကို ဒီ File ေပၚမွာပါ အသံုး ျပဳႏိုင္ပါတယ္ဆိုတာ ကိုေျပာပါမယ္ … Partition တခုကို mount လုပ္တဲ့ ပံုစံလိုပါပဲ...

#swapon /additional-swap

swapon commandနဲ႕ swap space ကိုျပန္ check ၾကည့္ရေအာင္..

#swapon -s

additional-swap ဆိုတဲ့ file ကို swap space အျဖစ္ ျမင္ရပါျပီ..

အဲဒီ additional-swap file ကို system BOOT တက္တာနဲ႕ auto mount ျဖစ္ေနေအာင္ fstab ထဲမွာ ဝင္ေရး ပါမယ္..

#vi /etc/fstab

ေအာက္ပါ အတိုင္း ဝင္ေရးပါမယ္..

/additional-swap swap swap defaults 0 0

ဒါဆိုရင္ Swap Space မလံုေလာက္တဲ့ Problem အဆင္ေျပ သြားပါျပီ....

လက္ရွိ IPv4 network ထဲမွာ IPv6 နဲ႕ပါ အလုပ္လုပ္ ရေအာင္ (IPv6 DHCP)

2012-01-26T02:09:00.001-08:00

တခါတရန္ IPv4 Network ထဲမွာ IPv6 ေတြနဲ႕ run ဖို႕ / မိမိ webapp ေတြကို IPv6 ေတြနဲ႕ေရာ အဆင္ေျပ ပမလား ဆိုျပီး testing လုပ္ဖို႕ လိုအပ္ လာရင္ IPv4 Network မွာ IPv6 address ပါတြဲ ျပီ လိုအပ္လာ ပါမယ္...

- Network မွာ IPv4 နဲ႕ လက္ရွိ run ေနျပီ လို႕ယူစပါတယ္..
- လက္ရွိ network မွာ IPv4 အတြက္ DHCP ရွိျပီးသားလို႕ ယူစ ပါတယ္
- ယခု SAMPLE သည္ Local Only အတြက္သာ ျဖစ္ပါတယ္
- သာမန္ Linux OS (recommended kernal 2.6.x) တခု နဲ႕ လုပ္မွာပါ (IPV6 ready ျဖစ္ဖို႕ ဒီ kernal ကိုသံုးတာပါ)
- လိုအပ္တဲ့ Package ကေတာ့ radvd (Router Advertisement Daemon)ပါ..

စျပီး လိုအပ္တဲ့ package radvd ကို install လုပ္ပါမယ္..
#apt-get install radvd

သူ႕ radvd.conf file က /etc ေအာက္မွာ သာမန္ automatic ပါမလာပါဘူး အဲဒါေၾကာင့္ radvd.conf file ကို manually လုပ္ပါမယ္
#vi /etc/radvd.conf

     အဲဒီ radvd.conf ထဲမွာ ေအာက္ပါ အတိုင္း configuration ေရးပါမယ္

interface eth0 {
        AdvSendAdvert on;
        MinRtrAdvInterval 3;
        MaxRtrAdvInterval 10;
        prefix 2001:1000:1000:1000::/64 {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};

(ဒီမွာေတာ့ eth0 network card ကေန IPv6 address ေတြကို release လုပ္မွာပါ | Global Unicast Address နဲ႕ပဲ သံုးပါမယ္ )

IPv6 ကို Allow ေပးဖို႕ /etc/sysctl.conf မွာသြား ျပင္ပါမယ္..
#vi /etc/sysctl.conf

ေအာက္ပါ စာေၾကာင္း ကိုရွာျပီး ထို စာေၾကာင္း ေရွ့က "#" sign ကို remove လုပ္ျပီး vaule ကို "1" သို႕ ေျပာင္းေပး႐ံုပါပဲ

"net.ipv6.conf.all.forwarding=1"

ေျပာင္းလိုက္တဲ့ value active ျဖစ္ေအာင္ ထို module ကို reload ျပန္လုပ္ပါမယ္..
#sysctl -p

radvd service ကို start လုပ္လို႕ ရပါျပီ..

     ဒါဆိုရင္ အခု config လုပ္ထားတဲ့ ဒီစက္ကေန network တခုထဲမွာ အတူတူ ရွိတဲ့ စက္ေတြဆီ ကို သူကေန IPV6 address ေတြကို release လုပ္ေပးေနပါလိမ့္မယ္..

Window 7/Linux/.. ေတြမွာေတာ့ IPV6 Address ကို Auto ရမွာပါ..Window Xp ေတြမွာ IPV6 ကို Install လုပ္ဖို႕ ေအာက္ပါ command ကို cmd ထဲမွာ သံုးေပးရပါမယ္...
"netsh int ipv6 install"
ref: http://support.microsoft.com/kb/2478747

Note:
     radvd ကို DD-WRT (open source firmware) နဲ႕လဲ setup လုပ္ႏိုင္ပါတယ္ ( Linksys wrt54g တလုံးရွိခဲ့ရင္)
           ref: http://www.dd-wrt.com/wiki/index.php/IPv6
     အကယ္၍ IPV6 only website ေတြကို အသံုးျပဳ ခ်င္တယ္ဆိုရင္ေတာ့ (သင့္ WAN IP က Public IP ျဖစ္ဖို႕ေတာ့ လိုအပ္ပါတယ္) tunnelbroker နဲ႕ IPV6 over IPV4 (Dual Stack) လုပ္ျပီသံုးႏိုင္ပါတယ္ ( 6to4 tunneling service အတြက္က http://tunnelbroker.net/ လို site ေတြမွာ FREE SignUp လုပ္ျပီး သံုးႏိုင္ပါတယ္)
           ref: http://en.wikipedia.org/wiki/List_of_IPv6_tunnel_brokers
     ေနာက္တနည္းက Teredo Tunneling နဲ႕လဲ သံုးႏိုင္ပါေသးတယ္..ဒီနည္းကေတာ့ မိမိ စက္တ လုံးထဲ အတြက္ ပဲဆိုရင္ အေကာင္းဆုံးပါပဲ
