Using cron to run sql script is a good idea to apply with a periodic database job. When running any scripts, cron doesn't know any environment variable. So, in the script, we always -use full path with execute command. -define all environment variable. ex. to see data in customer table in oracle database and log in customer_rpt.log, I create sql script[testsc1.sql] like this [oracle@oracle1 ~]$ cat testsc1.sql spool /home/oracle/customer_rpt.log select * from customer; quit; [oracle@oracle1 ~]$ next create shell script file to run sql script file. [oracle@oracle1 ~]$ cat mydbshell.cron #!/bin/bash ORACLE_HOME=/u01/app/oracle/product/10.1.0/db_1; export ORACLE_HOME; ORACLE_SID= my_sid ; export ORACLE_SID; /u01/app/oracle/product/10.1.0/db_1/bin/sqlplus user/password @/home/oracle/testsc1.sql [oracle@oracle1 ~]$ note that oracle_home, oracle_sid variable must be defined and sqlplus command called with full path. Now, we define new cron job by 'crontab -e' in console and make...

nano editor is no syntax highlight for any language by default. It is only black and white as in the picture below. To enable syntax highlight, you can uncomment the line [# include "/usr/share/nano/ruby.nanorc"]in /etc/nanorc[for global effect]. Or if you just want this effect to your user only. create ~/.nanorc and include default[sample] language specific config file from /usr/share/nano. Here is my java syntax highlight .nanorc file include "/usr/share/nano/java.nanorc"

I start upgrading to Gutsy on last Friday night with slow speed. Estimate time to finish package download is vary from 3 hours to 2 days depend on speed it get at that time so I just go to bed and come back again on Saturday 11AM. Downloading is finished it waiting for my response to config some package to install. After that it reboot and try to startx first time and fail!! It ask me to config my display.Monitor are detected correctly[dell 1905FP] but resolution only give me 800x600. I go to Graphic Card tab, the driver said vesa. At this point if I go to choose nvidia or nv x will fell to failsafe xserver and reconfig my xorg.conf to use vesa driver. Checking on Xorg.0.log I saw my old friend. "The NVIDIA kernel module does not appear to be receiving interrupts". Nvidia driver is installed but on Gutsy my "acpi=off irqpoll" kernel option doesn't seem to work anymore. I stumble many kernel option for three days and last night I found that for my gutsy it need t...

Look like everyone try to upgrade now, maybe I should be patient and wait for one or two days. Update-manager has a hard time to connect to server. I have 1M adsl but download upgrade tool give me 7KB/S.

Gutsy is already released now. It should be better to have original updated Feisty before upgrading. I mean no software from 3rd party repos. What I have are wine, fm2007[under wine] and compiz-fusion. First uninstall FM2007 leave me some menu entry that i need to manually delete it. I will post about this later. Afterthat i remove wine then compiz-fusion. Compiz-fusion set has a few packages installed and I can't remember the names what i do is .. pnix@pnix-a7n:~$ echo "sudo aptitude remove "`sudo dpkg -l |egrep compiz| awk '{print $2}'`|sudo bash Reading package lists...

So for now my solution is no eye-candy when use java apps.

It's about a week from today that Gutsy[ubuntu 7.10] will come out. I read through new feature in beta version and feel enthusiastic to see the change. - new gnome2.2, it's new feature here . - compiz fusion will be in official repos. that good, on feisty i use third party repos. and sometime got error when updating for last few weeks. - ntfs writing enable. i rarely need to write file on ntfs partition, anyway it may be useful. - automatic printer installation, this will be great for other[I have no printer at my house] I really hope that my hardware[athlonXP1700+,512DDR,fx6200 and A7N8X-E] can run gutsy with 3D effect smoothly.:)

I've got a problem with my desktop box again and look like it's happen periodically [every 5 months I think]. In the box, I have two hard drives. The new one, sata, is installed as dual boot disk, feisty and xp and another is 5 years old ide. I use it to store some unimportance files. Yesterday I start up ubuntu and can't mount the old one. It made some noise at boot time but this is nothing weird, It's sound terrible like this every day. The difference is this time it can't mount. Until now I still not sure my old ide is bad. Almost parts in the box are almost 5 years old, it can die at anytime. Maybe it's power supply, I don't know, it run at least 5 hours a day everyday for almost five years. Anyway my main SATA still healthy. I found this thread on ubuntuforums, he said ubuntu kill his laptop drive.

Momo Sissoko scores his first goal for liverpool after playing 75 games. It's also the 7000th league goal for the club since Malcolm McVean got the first goal a century ago. Yesterday [actually it's few hours ago] at the stadium of light, Liverpool got 2-0 won over Sunderland from Sissoko in 37th minute then confirmed by Andriy Voronin at almost the end of game. Very very good start for this season.

To add more secure on ssh server it's good idea to make our server allow only user who has a key to login. Today I found this trick from ubuntuforums .

One thing I want to do for a long time is remove mounted partition icons that default show on my ubuntu desktop. Nothing wrong with those icons, it's just too many icons and some I never go to browse into it. Now what to do. Open gconf-editor by hit [Alt+F2] and type gconf-editor. Go to apps->nautilus->desktop then check out "volume_visible". You can also customize others as you want like adding computer and trash icon to your desktop.

The pdf file [as I understand] encapsulate text, images and fonts so it should give me same result on any os. Many of pdf files I have are generated on windows and use windows fonts. When I open these files with evince [default document viewer] some can't render fonts correctly because windows fonts aren't embedded and not exist on ubuntu too. What I need to do is make application has correct fonts to use. There are two places that we can add fonts, the first is on server[Xserver] side and the second is on client side. Here I choose second choice by copy fonts required by the document from windows to $HOME/.fonts then caching new fonts by run command 'fc-cache -fv .fonts'.

Have you ever want to know Where is the files go when you install any package? or What package this file belong to? This post is about some package utility command that I've use many time but never remember. To list all files in the package. dpkg -L package-name rpm -ql package-name To find out which package[ we installed ] contains this file. dpkg -S file rpm -qf file To list installed package. dpkg -l rpm -qa To find out which package[ we not installed ] contains this file. apt-file search file yum whatprovides file Many situations in linux that you're complained about missing some library file to do something. Use this command to find the required package.

Update I just found that this problem is about xorg.conf. After add code below it gone Section "Extensions" Option "Composite" "Enable" EndSection ------------------- Sometime when enable compiz-fusion with compiz --replace Window border will disappear and it's not comeback after restart X or even restart system[in my case]. To bring window border back, Alt-F2 then type metacity --replace Don't know why but it's work beleive me. After run this command your desktop will have no 3D effect, now you can try enable compiz again.

Today I'm looking for mp3 player for my ubuntu. Feisty come with rhythmbox but after few months using I think it's time to try something better. Rhythmbox does not let me edit idv3 tags and [for me]it's hard to manage library so it's not acceptable. All I wants are a) idv3 tags must editable. This is important for me because some of my mp3 collection don't have info in tags or some have a wrong info. b) full support thai language. c) gtk+ application will be good.

The problem about playlist on media player are unreadable when it use thai character. This is caused by different encoding used in id3 tags and in media player. Id3 tags use cp874[don't know why] but in current linux distribution, player use unicode. This will not be a problem if tags are english characters that cp874 and unicode has the same value e.g. 'A' is '0x41' for cp874 and '0x0041' for unicode, but not for thai character. To correct thai character in playlist. There is a script to convert 1-byte charsets to unicode[ download ] by Kopats Andrei. Now what to do: 1. download the script. You'll get 'tag2utf.py'. 2. install requirement software sudo apt-get install python-eyed3 3. in the script, looking for charsets = {'cp1251':'c','koi8-r':'k' } and replace with your language encoding[ for thai change it to charsets = {'tis-620':'t' } ] Now we ready to convert mp3 tags. run script by 'tag2u...

Today I upgrade utorrent[sure on feisty] from 1.6 to 1.7 then restart utorrent. This upgrading cause unused parts of uTorrent's window are black. That's annoying me. After some searching, look like it wine bug , I run with wine 0.9.40, the newest one. The black window area will happen when use in mode

JSP is the html page that add java code[called JSP tags] into it. JSP tags can be devided into 6 different types. These are: Comment tag use to add comment. <% --comment here-- %> or <! --comment here-- > Declarations tag use to define the variables,methods or classes to use in the JSP page. <%! Declaration1; Declaration2; %> Scriplets tag use to insert java statements. <% Statement 1; Statement 2; Statement n; %> Expressions tag use to print out any data on the page. These data are automatically converted to string. <%=[Value] or [Expression]%> Directives tag is used for many purposes depend on directive and attribute in tag. there are three directives page, include and taglib. <%@ directive attribute="value" %> Action tag is use to transfer control to other server objects[ex. pages] or perform operations on other objects. <jsp:action attributes /> action tag has three types e.g. include,forward and usebean.

Two weeks ago, I read on ubuntuforums and found this thread about how to get compiz fusion work on ubuntu fiesty . It show you clearly step by step how to. Today I'm just decide to try and it's real amazing. 3D Cube and many effect feel smoother than the old compiz from repos. It's work on my asus n6200td 128M card, my memory is 512M, athlon xp 1700+ and A7N8X-E mobo. Compiz fusion still development version but for me it's very very very stable. So I urge you to try it now. Compiz Fusion is merging of compiz and beryl project. It's not on feisty repos yet but may be on Gutsy Gibbon.

Usually when I want to make a request over network in java I familiar to use Socket class like this. Socket theSock = new Socket(server,port); PrintStream ps = new PrintStream(theSock.getOutputStream()); then uses ps.println() to send a request and uses theSock.getInputStream() to reciece response to see everything that sent over output stream. But this maybe not suitable for all situation. Talking with web server will be done through HTTP message[request,response] that consists of header and body . So to make a post,get http request [with Socket class] //Post ps.println("POST uri HTTP/1.1"); ps.println("Content-Length: "+body.length()); ps.println("Content-Type: "+contenttype); ps.println(); ps.println( body ); //or Get ps.println("GET uri HTTP/1.1"); ps.println("Connection: Close"); ps.println(); and web server will responds with HTTP response like. Here's the example. HTTP/1.1 200 OK Date: Wed, 04 Jul 2007 10:14:54 GMT . Conte...

Last week I need to post data in xml format to one server. For security reason one node[xml] require 3DES encryption and encode to Base64 before send. It's a good idea to encrypt sensitive data before store in database or transfer over internet but I'm not even know what 3DES is. After some search, I found that it's not too hard. This post is about how i encrypt data in java. 3DES algorithm use symetric key[secret key] to encrypt or decrypt data. So.. First define a key [ length must be 24 bytes ]. I do this by getBytes() from random string. byte [] seed_key = (new String("er48nsjhwlG593mjhgdb20ih")).getBytes() create Cipher object SecretKeySpec keySpec = new SecretKeySpec(seed_key,"TripleDES"); Cipher nCipher=Cipher.getInstance("TripleDES"); nCipher.init( Cipher.ENCRYPT_MODE, keySpec ); Cipher class provides the functionality of a cryptographic cipher for encryption and decryption. To create cipher object, pass transformation to getInstance m...

If you run vsftp as your ftp server, may be you want to config in /etc/vsftpd/vsftpd.conf To disable anonymous ftp logins, change anonymous_enable to NO [Default: YES] anonymous_enable=NO To jail some user in their home dir uncomment two following line [Default: NO] chroot_list_enable=YES chroot_list_file=/etc/vsftpd/chroot_list and put a list of user [to be jailed] in /etc/vsftpd/chroot_list. Note that if chroot_local_user set to YES, meaning of list will be a list that not to be jailed. To jail all user in their home dir, add chroot_local_user=YES [Default: NO] chroot_local_user=YES

Even the "desktop effects" is just technology preview on Feisty. It still has some bugs but I like it. To enable go to System > Preferences > Destop Effects, then click "Enable Desktop Effects" button. It has two effects for now[as I known], "Windows wobble when move" and "Workspaces on a Cube". After enable it, windows wobble is work fine but not the cube effect. Notice that number of workspace will change to 1. If set it back to 2, when I change workspace[e.g. Ctrl+Alt+->] sometime it loose both panels[top and bottom] or sometime it give me blank screen[no panel,no icon] To make cube effect work open terminal and pnix@pnix-a7n:~$ gconftool-2 --type int --set /apps/compiz/general/screen0/options/hsize 4 pnix@pnix-a7n:~$ gconftool-2 --type int --set /apps/compiz/general/screen0/options/number_of_desktops 1 or use gui tool by type "gconf-editor" in terminal And navigate to: apps > compiz > general > screen0 > optio...

I known that to mount iso file pnix@pnix-a7n:~$ sudo mount -o loop file.iso mountpoint or pnix@pnix-a7n:~$ sudo mount -o loop -t iso9660 file.iso mountpoint and for cue/bin file ,I convert it to iso first use bchunk pnix@pnix-a7n:~$ bchunk file.bin file.cue file.iso but how about the others. After some search, I collect tips to handle many types of image file in linux. For nrg [ nero image ], img [ clone cd] and mdf [ alcohol 120% ] files, We need nrg2iso, ccd2iso and mdf2iso to convert those image files to iso image. Luckily, All are in Feisty repos. pnix@pnix-a7n:~$ sudo aptitude install nrg2iso ccd2iso mdf2iso Reading package lists... Done Building dependency tree Reading state information...
