MAKE USE OF CALCULATOR

   

Whenever we want to do some typical calculations like Scientific, Statistical and Programmatic calculations and some sort of Unit Conversions, Date & mileage calculations we rely on some sort of apps or software (or) on the internet for which we need to download nor we should have an internet connection and many of us don`t know that we can use the built-in calculator in our PC (windows) which have all the above features.

Let`s have a look…….

This the Built-In calculator (in windows OS) we can use all
the above mentioned features like:-

1.  Scientific calculations

2.  Statistical calculations

3.  Programmatic calculations(hex)

4.  Unit conversions

5.  Date calculations

6.Worksheets(mortgage,fuel economy calculations)

==To use the Built-in calculator`s features==

                  

Open calculator->view->select features as depicted below

Scientific calculations

Statistical calculations

Programmatic calculations (hex)

Unit conversions

Date calculations

Worksheets(Mortgage,Fuel economy Calculations)

Note: Tested in windows 7 Ultimate only (I think it will be like this in earlier windows operating (like xp,vista) systems & later)

Solved Error: ORA-12154: TNS:could not resolve the connect identifier specified

Solved Error: ORA-12154: TNS:could not resolve the connect identifier specified

Here I am going to discuss about the specific error”ORA-12154: TNS:could not resolve the connect identifier specified” when user tries to connect to the database from 10g FORMS & REPORTS DEVELOPER.The problem can be solved by doing a little work, in a few steps, as illustrated below. 

After installing the oracle developer suite 10g, I tried to connect to the local database(10g) previously installed on my pc,but I end with the error”ORA12154:TNS:could not resolve the connect identifier specified” and can`t connect to the database,it was because when we install the database 10g a net service name “orcl” is automatically created and is used to connect to database through listener,the listener identifies the specific net service name(connect identifier) and establishes theconnection from where it is initialized, but what happen when we try to connect to database through FORMS & REPORTS DEVELOPER SUITE is the listener cannot identify the net service name(connect identifier),because it is being initialized from and by the FORMS & DEVELOPER SUITE ,To solve the problem and to connect to the database there are two ways

1) To Reconfigure the NET SERVICE NAME from the developer suite 10g.

2) To follow the following steps.

STEP 1

Navigate to the path where you installed database 10g >oracle>product>10.2.0(version)>db_1>network>admin

Eg: C:\oracle\product\10.2.0\db_1\NETWORK\ADMIN 

(Note here C:\ is my installation drive) 

There you will find a file named as “tnsnames.ora” copy that file

STEP 2

Navigate to the path where you have installed 10g developer suite>network>admin

Eg: C:\DevSuiteHome_1\NETWORK\ADMIN

and paste the file “tnsnames.ora” 

Then try to connect to the database

Connected
