How to Access a Oracle database using Oracle Sql Developer Tool

First you have to check the oracle connection details.

For this purpose use the Oracle Sql Developer Tool.

you can download it from this website.
http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html

After downloading it to your local machine, unzip it and click on the "sqldeveloper" application to install it.

If Java is not installed on the machine

First you have to install the "supported" java JDK version to your machine.
otherwise it will ask the JDK path to install it.

Provide the Java bin folder path.
ex:
C:\Program Files\Java\jdk1.6.0_21\bin

If Java is already installed in the machine.

Click on the add connection
Then fill these required fields.

Connection Name:any
Username: Correct username
Password: Correct password

hostname: IP address or "localhost"
Port : Default Port "1521" or the Correct Port
SID : Default "xe" OR Service Name : any

Encrypt or Decrypt Connection Strings in web.config.

Connection strings contain sensative informations like usernames and passwords.So as a good practice we should encrypt those connection strings.

First Methods -> Using "aspnet_regiis.exe" command line tool

1) Go to

Start ---> All Programs --> Microsoft visual studio 2008/2010 --> Visual Studio Tools --> 
Visual Studio 2008/2010 Command Prompt(Run as Administrator)

2)Type this command

To Encrypt

aspnet_regiis.exe -pef "connectionStrings" "C:\path_of_web_config_file"

To Decrypt

aspnet_regiis.exe -pdf "connectionStrings" "C:\path_of_web_config_file"

Second Method -> Using Coding

After asp.net 2.0, .net 2.0 provided a protected configuration method to encrypt or decrypt the Connection strings of a web.config file

use this namespaces in the header section of the page.
using System.Configuration;
using System.Web.Configuration;

Add a button to encrypt config file

Put this code inside the click event

Method 1 : RSAProtectedConfigurationProvider

   Configuration confg = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
            ConfigurationSection configSect = confg.GetSection(section);
            if (configSect != null)
            {
                configSect.SectionInformation.ProtectSection("RSAProtectedConfigurationProvider");
                confg.Save();
            }


Method 2: DataProtectionConfgurationProvider
     Configuration confg = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
            ConfigurationSection configSect = confg.GetSection(section);
            if (configSect != null)
            {
                configSect.SectionInformation.ProtectSection("DataProtectionConfgurationProvider");
                confg.Save();
            }



 Add a Decrypt button to decrypt a encrypted connection strings

Put this code inside the click event

Configuration config = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
   ConfigurationSection configSect = config.GetSection(section);
   if (configSect.SectionInformation.IsProtected)
   {
      configSect.SectionInformation.UnprotectSection();
      config.Save();
   }

Solution 1

Put this code inside the method when you instantiate the Firefox driver. 

FirefoxProfile myProfile = new FirefoxProfile();

myProfile .setPreference("network.http.phishy-userpass-length", 255);

myProfile .setPreference("network.automatic-ntlm-auth.trusted-uris","yourDomain");
