How Justdial Works Overview

About Justdial

Justdial, founded by V.S.S Mani, is one of the India’s leading local search engines. It’s grown by leaps and bounds, and now caters to over 25 million unique users across 240 cities in India. It employs over 4,000 people and has more than 125,000 SME advertisers today. And behind this successful business is none other than the “open” hand!

Functioning Of Justdial

Justdial relies on open source technology which supports scalability in a seamless manner. Just dial adopted CLAMP Stack, about 300 servers connecting 3500 workstations at just dial, are powered by this CLAMP stack. CLAMP stands for Cloud Flare + LAMP (LINUX, APACHE, MYSQL and PHP).

Significance of CLAMP

Justdail using Cloud Flare to extend the scalability of the LAMP stack from an individual machine to a global network. Cloud Flare cuts the load on a typical LAMP stack web server by nearly 70%. That allows you to put twice the load on a single server the LAMP burning out.

REDHAT AND LINUX

Just Dial chose Red Hat Enterprise Linux (RHEL) to power its servers, Ubuntu on the desktop front, MySQL, PostgreSQL and MongoDB for database management, and WebHuddle for Web conferencing and video conferencing. While performance, security of the platform and trust in Red Hat made Just Dial bet on RHEL, the optimal network stack in Ubuntu won Just Dial’s confidence in the Ubuntu OS. Moreover open source technologies helps in refining the search logic. 

Justdail search Functioning

The company uses a search engine called Sphinx, a standalone search engine, which is a full text search engine written in C code that designed well to integrate with SQL databases on its LAMP architecture that is where non database queries searches gains relevance. The built in drivers helps in fetching the data either via direct connection to MYSQL or PostergeSQL.

Why Open source

Reasons why Just dial Choses an Open Source Platform 
1) Secure 
2) High Performance
3) Flexibility 
4) Cost Efficiency 
5) Scalability 

Open source mainly reduces the cost burden for any concern. if anyone choses Microsoft, they would have bled paying the licensing fees for 4,000 desktops and 200 servers(in justdial). But Justdial paid only Redhat subscription fee and MYSQL’s golden ticket fee, which is minimum when compared to any proprietary vendor.

Maintenance of the infrastructure

Maintenance of such an infrastructure could have been a nightmare, especially with all the innovation embedded into it. With the support of Redhat and Just Dial’s fully equipped IT team, helped Justdial address this challenge without too much trouble.

How to give different colors for different rows in a table CSS | Different Colors To Row In Table CSS

In this tutorial I am going to Explain How to give Different Colors to Different rows in a Tables. Using CSS We can give different colors to different tables easily !!!

Look at the following code keenly, Because rows are defined with classes namely odd and even.

The header class is different.

Consider the html code

<html>

<head>

</head>

<body>

<table border="0">

<tr class="trhead" align="center">
<th>Row</th>
<th>Colors</th>
</tr>
<tr class="odd" align="center">
<td>odd row</td>
<td>blue color</td>
</tr>
<tr class="even" align="center">
<td>Even Row</td>
<td>Yellow Color</td>
</tr>
<tr class="odd" align="center">
<td>odd row</td>
<td>blue color</td>
</tr>
<tr class="even" align="center">
<td>Even Row</td>
<td>Yellow Color</td>
</tr>
<tr class="odd" align="center">
<td>odd row</td>
<td>blue color</td>
</tr>
<tr class="even" align="center">
<td>Even Row</td>
<td>Yellow Color</td>
</tr>
<tr class="odd" align="center">
<td>odd row</td>
<td>blue color</td>
</tr>
<tr class="even" align="center">
<td>Even Row</td>
<td>Yellow Color</td>
</tr>
</table>
</body>

If you paste the above code you will get a blank normal table.

In order to add color to it follow the below code. In this second piece of code I have added style to the table using CSS. Note that I didn't created a separate CSS file. I just given the CSS tag in the head tag using <style> tag.
Just see the below code to know how it woks.

The CSS code is:
<style>
.odd
{
background: blue;
}

.even
{
background: yellow;
}
</style>

Paste this CSS code in the head tag like in the below example. You will get different colours for your rows.

<html>

<head>

<style>
.odd
{
background: blue;
}

.even
{
background: yellow;
}
</style>

</head>

</head>

<body>

<table border="0">

<tr class="trhead" align="center">
<th>Row</th>
<th>Colors</th>
</tr>
<tr class="odd" align="center">
<td>odd row</td>
<td>blue color</td>
</tr>
<tr class="even" align="center">
<td>Even Row</td>
<td>Yellow Color</td>
</tr>
<tr class="odd" align="center">
<td>odd row</td>
<td>blue color</td>
</tr>
<tr class="even" align="center">
<td>Even Row</td>
<td>Yellow Color</td>
</tr>
<tr class="odd" align="center">
<td>odd row</td>
<td>blue color</td>
</tr>
<tr class="even" align="center">
<td>Even Row</td>
<td>Yellow Color</td>
</tr>
<tr class="odd" align="center">
<td>odd row</td>
<td>blue color</td>
</tr>
<tr class="even" align="center">
<td>Even Row</td>
<td>Yellow Color</td>
</tr>

</table>
</body>

Your output will be ...

If you want each row to be displayed in different colors just give a class to that row and right a CSS for that , Then you will easily display a table with multicolored rows. 

Just try it your self with diving colors to separate rows and columns, Feel free to post you doubt as comments here.
Hope this post would have helped you regarding building a table with different colors.

How to partition a width/class in css | partitioning width

How to partition a width/space/class in css | Partitioning width in Website | HTML

Some times designers may think on how to do partition in css. It is as simple as you like.

Consider a ID(container) whose width is 900 and height is 300 and name of the class is "container"(any name of your wish can be given).  

Then the CSS for the above is

#container                                  <!--- Class name --- !>

{
width: 900px;
height: 300px;
}

Let us partition the container(ID) into three partitions (three sub classes) and their names inner1, inner2 and inner3 respectively.

Then we have to write the CSS accordingly.



.inner1
{
width: 290px;
margin-right: 10px;          // Space Between two classes
float: left;        <!----- Must needed -----!> // This is where the partition takes place
}

.inner2
{

width: 290px;
margin-right: 10px;
float: left;
}

.inner3
{

width: 290px;
margin-right: 10px;
float: right;
}

How to use it in HTML !!! (Copy paste this following code in your html and you can see how a particular space is partitioned and will add fuel to your desire towards CSS and web designing )

<html>
<head>
<style>
#container
{
width: 900px;
height: 300px;
}
#container .inner1
{
width: 290px;
         // Space Between two classes
float: left;
height: 300px;
      <!----- Must needed -----!> // This is where the

partition takes place
}

#container .inner1
{
width: 290px;
margin-right: 10px;
float: left;
height: 300px;
}


#container .inner2
{
width: 290px;
margin-right: 10px;
float: left;
height: 300px;
}

#container .inner3
{
width: 290px;
margin-right: 10px;
float: right;
height: 300px;
}
</style>
</head>
<body bgcolor="yellow">
<div id="container">
<div class="inner1">
<p> This space occupies 300 pixels of width and floats to

the left </p>
</div>
<div class="inner2">
<p> This space occupies 300 pixels of width and floats to

the left  follows the first class (inner1)</p>
</div>
<div class="inner3">
<p> This space occupies 300 pixels of width and floats to

the right  follows the second class(inner2)</p>
</div>
</div>
</body>
</html>

Your Output is:

After copy pasting try it with your own contents and images etc., Note that width and height should be accurate.

imdp not recognized as internal or external Command | Error in importing dump oracle

imdp not recognized as internal or external Command | Oracle Error

When We try to import an oracle dump file we may get this error , The most probably the reason  for such error is simple. 

Consider the following command,

" <sql> impdp username/password dumpfile=dump_file.dmp log=impdpas.log schemas=schema_name "

When You execute that command, you will get the following error

'imdp' is not recognized as an internal or external command,
operable program or batch file.

Solution is that you are not supposed to execute the command in "SQL"command prompt.
You Should exit SQL command prompt and execute that in Normal CMD (windows command Prompt)

C:\Windows\system32>  impdp username/password dumpfile=dump_file.dmp log=impdpas.log schemas=schema_name

Hope This will help you to resolve your issue.
