Common OpenCart Errors and How to Solve Them

Common OpenCart Errors and How to Solve Them

There is nothing more excited then try to build your own ecommerce store. Installing OpenCart extensions and themes, modificate them to your need and learn new thing during development. But most OpenCart users know how frustrating it can be get an unexpected error and not be able to find a solution for it.

Most OpenCart issues are solvable. If you got an error, don’t fret because other OpenCart user had the same problem and already gotten it solved. This tutorial collecting most common errors that repeatedly asked by OpenCart users at community forum. Sometime the same error have different error messages, that why we organize the error variant and solution for it.

Before continue, you need to know that an error usually trigger another errors. This is commonly happen because when your code breaks, the rest of code will not work and cause another error. No need to be confuse, the first error is the key. Recognise the error, find issue in your code and try to solve them with solution as suggested on this tutorial.

1. Blank White Pages or 500 Internal Server Error

Blank white pages is a PHP errors that for some reason the error messages isn’t show because your server is not setup to display the errors. While the 500 Internal Server Error means something has gone wrong but the server cannot specifically state what the exact problem is.

The similiarity of both issue is it doesn’t give us a clue what exactly happen, or what files triggering the errors. So, first step before we try to solve the errors is try to show the error messages. Then use the error message as starting point to investigate what is the error cause. Here are a few ways to show the error messages:

  1. Set your “Output Compression Level” to 0 in the System > Settings > Server tab.
  2. Then open php.ini and add code below: 1 2 3 display_errors = 1;error_reporting = E_ALL;log_errors = 1;
  3. If your server not read the php.ini, we will use an alternative method. Open index.php and add code below at the top (line 2): 1 2 3 ini_set('display_errors', 1);ini_set('log_errors', 1);error_reporting(E_ALL);
  4. When you have fixed the problem, remove code line above.

2. Undefined Index / Variable

The error appears when you referencing variable that not been declared. In programming approach set the variable or use isset() to checks if the variable has been set will solve the issue. But for an application to get this issue mean there is a bugs in it, whether it’s OpenCart or extensions files. Or you do some modification on unappropriate way.

Error variant:
  • PHP Notice: Undefined index: company in /path/public_html/catalog/model/account/customer.php on line 8
  • PHP Notice: Undefined variable: order_id in /path/public_html/catalog/controller/account/order.php on line 149
  • PHP Notice: Undefined variable: product in /path/public_html/vqmod/vqcache/vq2-catalog_view_theme_default_template_product_product.tpl on line 272
Solution
  1. If you get this issue on clean OpenCart installation, share the bugs at OpenCart forum. It will help OpenCart developer to develope bugs fix.
  2. When you get this issue after installing an extension, disable the extension then report it to the developer.
  3. If the error refer to file inside the “/vqmod/vqcache” folder, it’s mean the error caused by vQmod file. Disable the vQmod file by rename it to vqmod_file.xml_ and report the bugs to the developer.

3. Undefined Function / Method

If you get “Fatal error: Call to undefined function” or “Fatal error: Call to undefined method” means you try to call the function/ method that doesn’t exist. Commonly happen if files is not uploaded properly or the extensions is not compatible with your OpenCart version; or it’s really doesn’t exist. Here, I will try to classify the problem based on error message.

Error variant:

Related to OpenCart core files

  • Fatal error: Call to undefined function utf8_strlen() in /path/public_html/system/helper/utf8.php on line 39
  • Fatal error: Call to undefined method Customer::isLogged() in /path/public_html/catalog/model/catalog/product.php on line 8
  • Warning: require_once(/path/public_html/system/library/customer.php) [function.require-once]: failed to open stream: No such file or directory in /path/public_html/index.php on line 22
  • Fatal error: require_once() [function.require]: Failed opening required‘/path/public_html/system/library/customer.php’ (include_path=’.:/usr/lib/php’) in /path/public_html/index.php on line 22

Related to vQmod files

  • Fatal error: Call to undefined method ModelAccountCustomer::getPaymentAddress() in /path/public_html/vqmod/vqcache/vq2-catalog_controller_checkout_confirm.php on line 38

Related to PHP built-in functions

  • Fatal error: Call to undefined function imagecreatefromjpeg() in /path/public_html/system/library/image.php on line 34
  • Fatal error: Call to undefined function mysql_connect() in /path/public_html/system/database/mysql.php on line 6
Solution

Related to OpenCart core files

  1. Some file is not uploaded or it’s corrupted during upload process. Reupload the files to your server with ASCII mode, not binary.
  2. In some case, this issue appear because server path is not configured properly at config.php. So recheck your server path in config.php and admin/cofig.php
  3. “Warning/ Fatal error: require_once” mean the file is not available. You need to reupload the file mentioned on the error message or fix the server path at config.php as mentioned above.

Related to vQmod files

  1. vQmod fails to generate new cache from the extensions vQmod files. Check vqmod/cachefolder permission, make sure it’s writable and clear all cache files.
  2. Enabled / disabled one by one vQmod files you have. Once you get the cause, contact the developer.
  3. The extensions is not compatible with your OpenCart version or it have a bug. Contact the developer.

Related to PHP built-in functions

  1. PHP have lot of built-in functions, you can check it here. Errors related to PHP built-in function is server issues. Contact your host to solve this.

4. Headers Already Sent

You get an error message “headers already sent” right after installing, modificating, updating OpenCart or vQmod files. There is a good refference explaining the issue.

Error variant:
  • Warning: Cannot modify header information – headers already sent by (output started at /path/public_html/config.php:31) in /path/public_html/index.php on line 175.
  • Warning: session_start() [function.session-start]: Cannot send session cookie – headers already sent by (output started at /path/public_html/config.php:31) in /path/public_html/system/library/session.php on line 11.
  • Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at /path/public_html/config.php:31) in /path/public_html/system/library/session.php on line 11.
Solution:

Download the file stated at the error message then apply solution bellow:

  1. Remove spaces at begining and end of file. 1 2 3   <?php //contain spaceecho"remove all space or line-break before <?php and after ?>";?>
  2. Resave the file with Notepad++ or other editor (encode file as ANSI or UTF-8 without BOM).
  3. Reupload to server through FTP in ASCII mode, not binary.

5. Session Issue

PHP session store user information on the server for later use (i.e. login status, shopping items, etc) across the page requests. Session is temporary information and will be deleted after the user left the website. OpenCart use session on lot of aspect like login status, product cart, compare etc. In most case, session issue will throw error messages. But there is time when it’s not show any error message; to recognise it, here is some indication of session issue:

  1. Product on the cart is self-cleared.
  2. Product on the cart is cleared after user logged in.
  3. No items stored at product compares.
  4. OpenCart admin always asking to login and get message “Invalid token session. Please login again”.
Error variant:
  • Warning: session_start () [function.session-start]: open (/tmp/sess_41abirkdiesf9efwej46wtib2, O_RDWR) failed: No such file or directory (2) in /path/public_html/system /library /session.php on line 11
  • Warning: session_start () [function.session-start]: open (/tmp/sess_41abirkdiesf9efwej46wtib2, O_RDWR) failed: Permission denied (13) in /path/public_html/system /library /session.php on line 11
  • Warning: session_start() [function.session-start]: open(/tmp/sess_41abirkdiesf9efwej46wtib2, O_RDWR) failed: No space left on device (28) in /path/public_html/upload/system/library/session.php on line 11
Solution:

No such file or directory issue

  1. Open php.ini and add code below: 1 session.save_path = /tmp;
  2. If solution above not work, contact your host and ask them how to set session.save_path.

Other errors

  1. “Permission denied”, ask your hosting to check the session directory permission.
  2. “No space left on device”, ask your hosting is it server issue or you need to upgrade to larger hosting space.

6. Allowed Memory Size Exhausted

This error happen because your memory is not enough to execute the php code (uploading large image, delete lot of products, send mass mails etc). Increasing the memory allocated for PHP will solve the issue.

Error variant:
  • Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 47200 bytes) in /path/public_html/system/library/image.php on line 34
  • Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 13069817 bytes) in /path/public_html/system/library/mail.php on line 144
  • Fatal error: Out of memory (allocated 33554432) (tried to allocate 14024 bytes) in /path/public_html/library/image.php on line 34
Solution:

Apply one of solutions bellow to increasing the limit to 64MB, 128MB, 256MB or 512MB -depends on your host.

  1. Edit php.ini 1 memory_limit = 128M;
  2. Or put code below to .htaccess 1 php_value memory_limit 128M
  3. If you oftenly get this error and solution above isn’t work, contact your host. In most shared hosting, there is maximum memory_limit. You can’t set memory-limit to 64Mb if you get max 32Mb.

7. Restriction in effect

You get an error message “SAFE MODE Restriction in effect”. This is a PHP restriction issue, and your server account is trying to run a -builtin PHP- functions but doesn’t have access to run it. This issue is nothing to do with OpenCart, but related to your server configuration.

Error variant:
  • Warning: session_start() [function.session-start]: SAFE MODE Restriction in effect. The script whose uid is 10025 is not allowed to access /path/public_html/system/library/session.php on line 11
  • Warning: imagejpeg() [function.imagejpeg]: SAFE MODE Restriction in effect. The script whose uid is 10305 is not allowed to access /path/public_html/image/cache/data owned by uid 48 in /path/public_html/system/library/image.php on line 44
  • Warning: is_dir(): open_basedir restriction in effect. File(/path/public_html/image/87cngmlc22pe96fof5fhmq9c290phri7) is not within the allowed path(s): (/path/server/) in /path/public_html/catalog/controller/checkout/confirm.php on line 248
Solution
  1. Safe Mode and open_basedir restriction is a server issue, ask your host to turn off the restriction is the best way to fix the issue.
  2. But in case you wanna try to resolve it, try this solution: 1 2 3 4 5 6 7 // Put code bellow at php.inisafe_mode = Off;--- or---// Put code bellow at .htaccessphp_value safe_mode off

Usefull Tools

System Information

System Information provide server information, PHP built-in functions and file/ folder permission that required or recomended by OpenCart. This extension will help you to monitor that your site / server meet OpenCart requirements to work well. You can download it at OpenCart Marketplace.

vQmod Manager

vQmod Manager allows users to managing vQmod files. This extension display vQmod file information and help you to manage (Upload, delete, install, uninstall and backup) and monitor the vQmod files through the admin panel. You can download it at OpenCart Marketplace.

The Top 3 Reasons an Application Hangs

The Top 3 Reasons an Application Hangs

Do you experience application hang problems? If so, read this article to discover the top 3 reasons applications hang and cause slow performance.

If you have been in the IT industry long enough, you probably know this story well. The application works fine, then, suddenly, the application hangs with no apparent reason. You restart the application and it all goes away.A week passes, maybe two, and then the application hangs again. Another restart and you’re back. It doesn’t crash or fail (no crash dump or thread dump)—it just sits there and hangs. No users are being served.

Eventually you decide to just restart every night hoping it will not hang again. It doesn’t matter if you’re using a Tomcat application server, WebSphere, WebLogic, JBoss or whatever — if you have been in the software development business long enough, you must have experienced this problem. This is where application monitoring can help.

Below are the top 3 reasons why an application server hangs:

Reason #1: it’s a database problem.

This may sound strange, but the main reason an application server hangs is not directly related to the application server itself. The location of the symptom is rarely the location of the root cause. The following scenario is quite common:

  • The database is bottlenecked, causing queries to run slower than usual.
  • Requests that used to take 1 second, now take 5 seconds to complete.
  • The average number of concurrent requests slowly increases (due to backlog).
  • The server runs out of threads and the application server hangs.

If you manage to get a thread dump, you’ll just see a bunch of threads waiting and another group that’s actually running. Another possibility is that the number of waiting threads (or queued threads) will gobble up all available memory and, eventually, lead to an OutOfMemory error.

Reason #2: deadlocks.

If it seems that the application server is doing nothing, look for deadlocks. These can be database deadlocks that cause your SQL queries to hang, or seek the update statements. For example, a transaction log that is written to the database for each request may easily hang the entire application if the log table is locked. It can also be a deadlock of the application re-accessing itself. Do you have any HTTP SOAP calls from one application server to another? Also check for shared objects—an operating system file that is written to from multiple threads at once.

Reason #3: run-away thread.

In cases where the application server is indeed to blame, you should look for a run-away thread. These are hard to detect because they hardly show up on logs since they are usually only written when the request has completed. A run-away thread will probably not return until it has already affected the entire application. Therefore, the hanging request will not be written to the log. These ‘runaway’ threads typically include infinite loops in code. For example, a query that should show results that does not include the option of paging between result pages suddenly needs to display a large number of results. The page takes forever to render and clobbers the application server, eventually causing it to hang.

These types of application hangs are extremely difficult to diagnose and detect. The hardest part is isolating the root cause of the problem. If the application server hangs, it doesn’t necessarily mean that the problem resides there. It usually doesn’t. End-to-end transaction management tools, such as SharePath by Correlsense, helps to pinpoint the reasons for an application hang by providing a real-time view into the entire application behavior.

how to install laravel

how to install laravel

Install Composer

Laravel utilizes Composer to manage its dependencies. First, download a copy of the composer.phar. Once you have the PHAR archive, you can either keep it in your local project directory or move to usr/local/bin to use it globally on your system. On Windows, you can use the Composer Windows installer.

Install Laravel

Via Laravel Installer

First, download the Laravel installer using Composer.

composer global require "laravel/installer=~1.1"

Make sure to place the ~/.composer/vendor/bin directory in your PATH so the laravelexecutable is found when you run the laravel command in your terminal.

Once installed, the simple laravel new command will create a fresh Laravel installation in the directory you specify. For instance, laravel new blog would create a directory named blog containing a fresh Laravel installation with all dependencies installed. This method of installation is much faster than installing via Composer.

Via Composer Create-Project

You may also install Laravel by issuing the Composer create-project command in your terminal:

composer create-project laravel/laravel {directory} 4.2 --prefer-dist

Via Download

Once Composer is installed, download the 4.2 version of the Laravel framework and extract its contents into a directory on your server. Next, in the root of your Laravel application, run the php composer.phar install (or composer install) command to install all of the framework’s dependencies. This process requires Git to be installed on the server to successfully complete the installation.

If you want to update the Laravel framework, you may issue the php composer.phar updatecommand.

Server Requirements

The Laravel framework has a few system requirements:

  • PHP >= 5.4
  • MCrypt PHP Extension

As of PHP 5.5, some OS distributions may require you to manually install the PHP JSON extension. When using Ubuntu, this can be done via apt-get install php5-json.

Configuration

The first thing you should do after installing Laravel is set your application key to a random string. If you installed Laravel via Composer, this key has probably already been set for you by the key:generate command. Typically, this string should be 32 characters long. The key can be set in the app.php configuration file. If the application key is not set, your user sessions and other encrypted data will not be secure.

Laravel needs almost no other configuration out of the box. You are free to get started developing! However, you may wish to review the app/config/app.php file and its documentation. It contains several options such as timezone and locale that you may wish to change according to your application.

Once Laravel is installed, you should also configure your local environment. This will allow you to receive detailed error messages when developing on your local machine. By default, detailed error reporting is disabled in your production configuration file.

Note: You should never have app.debug set to true for a production application. Never, ever do it.

Permissions

Laravel may require one set of permissions to be configured: folders within app/storagerequire write access by the web server.

Paths

Several of the framework directory paths are configurable. To change the location of these directories, check out the bootstrap/paths.php file.

Pretty URLs

Apache

The framework ships with a public/.htaccess file that is used to allow URLs without index.php. If you use Apache to serve your Laravel application, be sure to enable the mod_rewrite module.

If the .htaccess file that ships with Laravel does not work with your Apache installation, try this one:

Options +FollowSymLinks
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]

Nginx

On Nginx, the following directive in your site configuration will allow “pretty” URLs:

location / {
    try_files $uri $uri/ /index.php?$query_string;
}

6 Essential Tips on How to Become a Full Stack Developer

6 Essential Tips on How to Become a Full Stack Developer

How to become a full stack developer? As one of the hottest topics for developers, the discussions have never stopped. On LinkedIn and Facebook, lots of people put their job title as a full stack developer. Besides, it seems that the “Full Stack” topic has already become a new job trend. An article on Medium has discussed the full stack designer getting both praise and blame. Some people think that the full stack is just a title, what he/she should focus on is the real personal ability and technology.

Essentially, I think the discussion about the full stack is also a kind of argument relating to the all-rounder and expert in the IT industry, and debate on the depth and breadth of development skills.

You can’t have your cake and eat it too. While the full stack developers and full stack designers seem like they are challenging this possibility. Because their horizontal skills tree gives them the ability to both have and eat the cake. There is another saying is that jack of all trades, but master of none. So it’s necessary to think about how to become a real full stack developer but not an empty title.

1. What is a full stack developer?

Simply put, full stack developer is a kind of people who master a variety of skills and use these skills to complete a product independently. A top voted answer on Quora explained that what is a full stack developer:

A full stack developer is an engineer who can handle all the work of databases, servers, systems engineering, and clients. Depending on the project, what customers need may be a mobile stack, a Web stack, or a native application stack.

In fact, “full stack” refers to the collection of a series of technologies needed to complete a project. “Stack” refers to a collection of sub-modules. These software sub-modules or components combined together to achieve the established function while without the need for other modules.

2. Why has the full stack developer been controversially discussed?

As it mentioned above, the discussion about full stack developer is actually the debate on the depth and breadth of skills. Especially at the OSCON conference, a Facebook engineer said they only hired a “full stack developer.” This topic came as a result of a heated discussion about the strengths and weaknesses of being a full stack developer.

Advantages: The full stack developers involved in a horizontal technical requirement, so that he/she can make a prototype design for a product very rapidly with his wide range of techniques. With the full stackability, they have a broader angle of views and a more active mindset. Moreover, they will be more sensitive to techniques and products. So, this kind of people can always have his/her opinions towards the product or design.

From another aspect, he/she can provide help to everyone in the team and greatly reduce the time and technical costs of team communication, technology docking. So many of them become entrepreneurs or as technical partners in start-up companies.

Disadvantages: It is precisely because of the horizontal technology development, some the full stack developers cannot be expert in one skill. Most of them who claim to be “full stacks developer” are only know a little about the multiple skills. As for how to make the architecture more suitable for the modular development, that’s a question.

3. Even so, there are still people asking, how to become a full stack developer?

A qualified full stack developer should have functional knowledge and capabilities for all aspects involved in building the application.

1) Programming languages

You need to be proficient in multiple programming languages, such as JAVA, PHP, C #, Python, Ruby, Perl, etc. As most of your core business processes need to be written in these languages.Maybe not all need. But you also have to master the language grammar, and to be very familiar with how to structure, design, implementation, and testing of the project based on one language or more languages. For example, if you choose JAVA, then you need to master the object-oriented design and development, design patterns, J2EE-based components of the development and so on.

Where to learn: Git/GitHub — You have to know how to use Git to manage and share your code.

2) Use development frameworks and third-party libraries

The popular development languages are generally accompanied by a good development framework, such as JAVA Spring, MyBatis, Hibernate, Python Django, PHP thinkphp, yin, nodeJs express and so on.

Where to learn: 15 free Python ebooks

3) Front-end technology

Front-end technologies are becoming more and more important in today’s project and product development. In addition to product features, the user experience is also one of the criteria to test the success of a product. All that depends on the implementation of the front-end technology, soyou need to master some basic front-end technologies such as HTML5, CSS3, JavaScript, and further study the front-end frameworks or third-party libraries such as JQuery, LESS, SASS, AngularJS, or REACT.

Where to learn: You don’t know JS

4) Database and cache

Any product or project needs a database to store data. As a full stack developer, you also need to have at least one or two databases and know how to interact with the database. Currently, the popular database is MySQL, MongoDB, Redis, Oracle, SQLServer and so on. As a document-type database, MongoDB, is being used more widely in Internet products. As for larger projects, Ialso recommend using MySQL or commercial Oracle as the back-end database. While memory databases, such as Redis, can be used for caching to improve system performance.

Where to learn: MongoDB MERN tutorial series, Redis tutorial

5) Basic design ability

Most of the articles or discussions about the full stack developer are rarely related to the design requirements. But I think the design skill is very important, the principle and skill of basic prototype design, UI design, UX design are also needed to understand.

Where to learn: UX blog

6) Self-requirements are also an essential factor to become a full stack developer:

  • Global thinking
  • Good communication skills
  • Creativity
  • Curiosity
  • Time management skills

Wrap Up

According to Gladwell’s 10,000 hours of law, it will spend 10 years to master the front-end, back-end, client-oriented knowledge content to be a full stack developer. Therefore, the full stack developer is by no means to accomplished overnight. What you need to do is laying the technical foundation, strengthen the core skills, and keep learning for more challenges.

What does the term “full-stack programmer” mean? What are the defining traits of a full-stack programmer?

What does the term “full-stack programmer” mean? What are the defining traits of a full-stack programmer?

A full stack developer is capable of performing tasks at any level of the technical stack in which they reside. It means:

  • Working with systems infrastructure (knowing what hardware to ask for , what OS to install, how to prepare the system and dependencies for all software)
  • Understanding, creating, manipulating, and querying databases
  • API / back-end code in one or more languages, e.g. Ruby, Java, Python, etc.
  • Front-end code in one or more languages, e.g. HTML, JavaScript, Java, etc.
  • Project management / client work, e.g. gathering requirements, creating technical specifications and architecture documents, creating good documentation, managing a project timeline (e.g., someone who knows Agile/SCRUM/Kanban)

In general a full-stack developer has knowledge that is a mile wide, but not necessarily very deep, and has core competencies in the pieces of the stack in which they work most.
In my work I have core competencies in Linux (Debian, CentOS, Amazon Linux), Database design, manipulation, and query (PSQL and MySQL), back-end technologies (Java, Ruby, and Python), and some front-end design (HTML, vanilla JavaScript, and jQuery), as well as act as SCRUM-master and lead Agile development for my team, interfacing with clients both internal and external to the business to gather requirements, execute tasks, and document all efforts.

Typically these skills are developed over many years in the contexts of different jobs, so as Ian mentioned being a full-stack developer means being pushed outside of your comfort zone to constantly learn new skills.

Want to have a good credit score? Avoid this costly mistake when paying credit card bills

Want to have a good credit score? Avoid this costly mistake when paying credit card bills

Want to have a good credit score? Avoid this costly mistake when paying credit card bills

It’s natural to fret about your credit score. Most Americans would do almost anything to improve it. Mistakes, of course, are bound to happen.

More than one in five credit card users have carried a balance to help improve their credit scores, according to a study released Monday by CreditCards.com. But carrying a balance is not one of the factors that comprises a credit score—and doing so could lead to more harm than good.

Leaving a balance past a payment due date causes cardholders to pay unnecessary interest, and could even negatively affect their credit score if the balance pushes their credit utilization too high.

Twenty-eight percent of millennials with a credit card said they have made this mistake, while only 25 percent of Gen-Xers and 16 percent of those age 54 and older admit to the same blunder.

The survey was conducted for the online marketplace CreditCards.com by market-research firm GfK, which gathered data last month from 1,000 Americans aged 18 and older.

“The fact of the matter is that carrying a balance will never improve your credit,” said CreditCards.com senior industry analyst Matt Schulz. “With interest rates at an all-time high, cardholders should aim to pay off their bills in full every month, and, more importantly, pay on time.”

Lower earners and those without a college education are also likely to fall victim to the misconception. Thirty percent of credit card users making under $50 thousand dollars per year have tried to improve their credit scores by carrying a balance, compared to 19 percent of those who earn over that amount. And 27 percent of cardholders without a college degree have done the same, compared to only 12 percent with a college education.

Many Americans are simply struggling to pay their credit card bills on time. Forty-two percent admit to paying a credit card bill late. And, once again, millennials tend to be the most habitual late-payers, with 10 percent reporting they have paid a late fee five or more times.

More than half of millennials said they paid a bill late because they did not have enough money at the time.

Train Cancelled? IRCTC To Credit Entire Amount To Your Bank Account

Train Cancelled? IRCTC To Credit Entire Amount To Your Bank Account

Train Cancelled? IRCTC To Credit Entire Amount To Your Bank Account

When your train is cancelled from the start station to the destination, then the passenger name record (PNR) is automatically cancelled and the credit is transferred to the bank account. The refunds are made in the same bank accounts from where the booking has been made. However, the passengers must note that when they cancel the tickets on their own, then some cancellation charges apply. For instance, in case of first AC/ executive class, the cancellation charges are Rs. 240.

In case the passenger traveled by the second A/C or first class, the cancellation chargeslevied by the IRCTC would be Rs. 200. In case of third AC/ACC/3A economy, the cancellation charges that IRCTC (Indian Railways Catering And Tourism Corporation) levies amount to Rs.180. However, for the second sleeper class, the IRCTC levies Rs. 120 as cancellation charges. When the passenger is cancelling the second class, the cancellation charges are Rs. 60.

When the cancellation is done anytime between 48 hours and 12 hours before the scheduled departure of the train, the charges are 25% subject the minimum as mentioned above.

And when the cancellation happens between 12 hours and 4 hours before the scheduled departure of the train, the cancellation charges will be 50% subject to the minimum charge.

There will be no refund after the above prescribed time limit which means if the ticket is cancelled anytime within four hours of the scheduled departure, there would be no refund of the ticket amount.

In a similar development, NDTV had reported that IRCTC, the e-ticketing arm of Indian Railways, has introduced a new payment mechanism for booking e-tickets, including Tatkal tickets. Now, IRCTC e-wallet users can book rail e-tickets including Tatkal quota tickets through mobile app IRCTC Rail Connect. IRCTC e-wallet is a payment mechanism which enables users to deposit money in advance with IRCTC. This money can be used as a payment option.

Aadhaar Virtual ID to be accepted from July. Here’s how to generate

Aadhaar Virtual ID to be accepted from July. Here’s how to generate

New Delhi: With the Unique Identification Authority of India (UIDAI) mandating the implementation of Virtual ID from 1 July, the way financial institutions have been verifying information about customers is going to change. Virtual ID is a 16-digit random number mapped with the Aadhaar number. It can only be generated, replaced or revoked by the Aadhaar number holder. “It will not be possible to derive the Aadhaar number from the Virtual ID,” a circular issued by UIDAI in January said. There will only be one active and valid Virtual ID for an Aadhaar number at any given time.

How to generate Aadhaar Virtual ID?

Aadhaar number holders can generate Virtual ID from the UIDAI website, Aadhaar enrolment center or the mAadhaar app. All that the user needs to ensure is that their mobile phone number is linked with the Aadhaar database so that they can receive an OTP or one-time password to generate VID. The facility has been rolled out by UIDAI from 2 April.

Why has Aadhaar Virtual ID been introduced?

The move is part of UIDAI’s initiative to put in place multi-layered security to reinforce privacy protection for Aadhaar holders. Virtual IDs allow Aadhaar number holders to share VID instead of their Aadhaar number during authentication, thus reducing collection of Aadhaar numbers by various agencies, said a UIDAI circular.

How to use it?

The Virtual ID can be used for the purpose of authentication in the same way the Aadhaar number is used. As of now, when a customer has to authenticate himself/herself to avail financial services, he/she has to give the 12-digit Aadhaar number and an OTP that he/she receives on the mobile phone.

From 1 July, the customer will not be required to give the Aadhaar number, instead the 16-digit Virtual ID will be provided to the agency or company.

Where to use Aadhaar Virtual ID?

UIDAI has introduced two categories of an Authentication User Agency (AUA)—an entity engaged in providing Aadhaar-enabled services. Local AUA, which is the limited KYC category and a global AUA, which will have access to e-KYC using the Aadhaar number.

An AUA may be a government, public or a private legal agency registered in India which uses Aadhaar authentication services provided by UIDAI.

All banks-commercial banks, payment banks, regional banks, rural banks, cooperative banks, small finance banks; life insurance companies and National Payments Corporation of India (NPCI) have been categorized as global AUAs whereas prepaid payment instruments (PPIs), non-bank financial institutions (NBFCs), telecom operators and non-life insurance companies are amongst those classified as local AUAs.

This means that if you want to authenticate yourself to avail services of any of these local AUAs, you will have to use Aadhaar Virtual ID. However, the use of Virtual ID for availing services of global AUAs is optional for users.

However, the global AUAs too have been instructed to upgrade their systems to provide authentication services using Virtual ID, said UIDAI in a circular issued on 6 June.

According to an industry expert, who did not wish to be named,Aadhaar Virtual ID has been introduced as an alternate ID for protecting privacy of Aadhaar number, especially for online customers doing OTP based e-KYC and authentication.

“ However, the distinction between local and global AUAs needs more clarity especially when KYC regulation and specific use cases are driving the classification among entities getting Global and Local AUA licenses,” added the person.

SURVEY: MAINSTREAM ADOPTION OF SDN, SD-WAN FINALLY ARRIVES

SURVEY: MAINSTREAM ADOPTION OF SDN, SD-WAN FINALLY ARRIVES

The top IT initiatives of enterprise network managers are cloud and software-defined data centers, overcoming server virtualization’s dominance for the past 10 years, according to Enterprise Management Associates.

In 2018, for the first time cloud and software-defined data-center concerns have become the primary focus of enterprise network teams, bumping server virtualization from the top spot, according to an Enterprise management Associates (EMA) report based on a survey of 251 North American and European enterprise network managers

This is the first shift in their priorities for in more than a decade. Since 2008, EMA has been asking network managers to identify the broad IT initiatives that drive their priorities. Server virtualization has dominated their responses year after year. Cloud and software-defined data center (SDDC) architectures have always been secondary or tertiary drivers.

In 2018, this pattern has finally broken, according to EMA’s “Network Management Megatrends 2018” research. This shift in drivers is also leading to mainstream focus on software-defined networking (SDN), network virtualization and software-defined wide-area networking (SD-WAN).

Server virtualization and workload consolidation

Before there was vCloud, OpenStack, Amazon Web Services, Microsoft Azure or even ESXi, there was simply VMware ESX. At its outset, VMware’s server-virtualization technology allowed enterprises to run more than one application on an x86 host, which allowed data center operators to consolidate workloads onto a smaller number of servers. Virtualization allowed enterprises to remove hardware, save rack space and drive efficiency in power and cooling. Virtualization also facilitated the decomposition of monolithic applications into multi-tiered application architectures, where different layers of an application could run on separate virtual machines.

This consolidation of workloads and the decomposition of applications that followed had profound impacts on networks. Bandwidth demand at the server access layer expanded, and the amount of traffic traveling east-west between servers exploded. Network engineers have spent the last decade reacting to this, building flatter, leaf-spine networks and replacing spanning tree protocol with equal-cost multi-pathing schemes.

That is why network managers have told EMA over and over again since 2008 that the broad IT initiative that most drives networking is server virtualization by a wide margin.

2018: software-defined and cloud architectures

While server virtualization remains influential on networking in 2018 (35% of network managers), it is no longer the top driver. This year, several other initiatives moved into a virtual tie with it, which indicates that mainstream enterprises are asking the network to support next-generation technologies. EMA asked network managers to identify all broad IT initiatives that were driving their priorities. The top driver in 2018 is SDDC architecture (37%). Other leading initiatives are infrastructure as a service (35%) and private cloud architecture (35%). Note that all these newly influential initiatives are ideas that draw on server virtualization as a foundational technology.

This data suggests an inflection point. For years, technology companies anxious to sell next-generation solutions have claimed this inflection point had already arrived, despite limited supporting evidence. Finally, EMA sees this shift in the numbers. Network managers are turning their focus away from east-west traffic optimization in the data center to programmable, software-defined technologies.

SDN and SD-WAN finally have their day

Network teams will naturally adopt new technologies to support these next-generation initiatives, and EMA research affirms this. In 2014 and 2016, network managers told us that network security and WAN optimization were the two most important networking initiatives they were dealing with.

Security is always a major concern, since the threat landscape is always evolving and challenging the security team. But WAN optimization is by no means a technology of the future. Its popularity always suggested that enterprises were focused on extracting more value out of their high-priced and bandwidth-constrained MPLS networks.

Network teams tasked with supporting cloud and SDDC architecture need to expand their technology focus. This year’s Megatrends research found just that. Network security (43%) remains at the top of the list, but data center SDN (40%), network virtualization (37%) and SD-WAN (36%) are near the top of the list. In previous years they were afterthoughts.

This shift in priorities suggests that mainstream enterprises are at last focused on these solutions after years of hype. Data center SDN and network virtualization are essential to private cloud and SDDC initiatives. They make the network more dynamic, agile and programmatic. Meanwhile, SD-WAN brings many of the same benefits to the WAN, and it facilitates the connection of remote sites to public-cloud environments.

WAN optimization (36%) remains relevant, but the rise of SD-WAN suggests that a tectonic shift is happening in the WAN, since SD-WAN enables enterprises to supplement or replace MPLS with broadband internet.
