Oracle Database Server X86 Gradually Heat Selection Guide

Based on past surveys, we know that the database Server When the selection has the following five principles: high-performance, high reliability, high scalability, security and manageability, etc.. In fact, a different database program on the server hardware requirements are different. Starting from this issue, we will focus on the most popular of several databases (Oracle/DB2/MySQL, etc.), analyze their specific needs and the server hardware market solutions.

For any enterprise, departmental-level database is already important and indispensable IT One-group, while most of these databases are produced by the Oracle Database software . Therefore, we first of all the latest on the Oracle Database 11gR2 on the server needs to do a simple analysis.

1, Oracle 11g database server component on the requirements of

Oracle 11gR2 support for unstructured data, the binary XML storage efficiency and significantly improved the speed of XML index increased by 15 times than before. On the other hand, Oracle added the results of server and client caching technology makes PL / SQL performance tripled, JAVA performance increased by 11 times. But all this means that the original equipment has been insufficient to carry the new version of the database caused performance. Experienced Oracle database administrators are aware that when dealing with Oracle products, the entire upgrade process is not only a need to upgrade to the latest version of the software and hardware upgrades are needed at the same time.

Since Oracle 11gR2 with RAC (Real Application Clusters) technology, the database can be distributed to a number of servers deployed in order to avoid make up a single server efficiency and ensure redundancy. But on the one hand the database synchronization and management problems, on the other hand also the quality of their professional DBA raised the additional demand. In contrast, administrators are more willing to use virtualization technology to deploy Oracle database, which can be better disaster recovery, fast backup, portability, performance and business continuity. This also brings the demand on the database server: virtual high-performance, Memory Large capacity and good reliability.

However, under normal circumstances, most IT departments, or follow the piece of “iron law”, that is, system design life cycle (SDLC), the existing technology or to maintain, unless the maintenance costs exceeded the cost of replacement products. We are experts in the post-face interviews with Oracle database, also found that upgrading the server when they are The first consideration is cost, performance and stability will only be considered after .

Question of cost, it is necessary that each procurement costs and operating costs, which are more and more seriously by corporate IT departments. Procurement cost point of view, is naturally more expensive RISC platforms, x86 platform occupied the unique low-cost high-performance advantages. On the other hand, the operating cost perspective, RISC environment because of their closed-source and proprietary platforms, the need for labor costs, operation and maintenance, software solutions require additional spending, while x86 platform as an open platform environment and general features , at lower cost.

This regard, is not surprising that many key business is moving from RISC + UNIX platform migration to the X86 + Linux platform. But the x86 platform has been the impression in performance RISC platforms are not as powerful, but also the stability of people’s criticism. What exactly is this?

What is Fine Grained Access Control for Row Level Security Deployment in Oracle Database?

Fine grained access control FGAC is a feature introduced in Oracle 8i. It allows the implementation of row level security on tables and views. Row level security provides a more granular level of security than previously available in Oracle.

There are lots of new terms related to the implementation of Fine Grained Access Control, and this feature can seem quite complex at first. You need to be familiar with Fine Grained Access Control. You should know what it’s used for and how it’s set up. You should also know what an application context is and how it’s set up.

Some basic benefits of Fine Grained Access Control are following.

Enhanced security- The policies set with the use of FGAC are stored on the server and cannot be bypassed by client software.

Flexibility- Dynamic and complex security policies can be enforced with the use of fine grained access control. This is because it is dynamic in nature and allows the database administrator to create powerful security protocols based on multiple criteria. Based on the various security criteria that are defined, final access decisions don’t need to be made until run time.

Transparency- Changes in security policies can be made without requiring change in application code.

Scalability- The SQL statements used are parsed, optimized, and stored in the shared pool, making them available to other users.

Security policies- A rule or set of rules that should be followed when a script or script set determines whether a particular user should have access to a specific row or set of rows of data in a table. Using fine grained access control, Oracle enforces security policies within the database itself. The enforcement of these policies is being native to the database rather than to an application provide greater security, simplicity, and flexibility.

Application Context is holding area for information that is useful to have easily available. You use the different functions and procedures command to create a context. Oracle also makes several default variables available.

Application security is the attachment of privileges and roles to access such that users won’t be able to misuse the roles or privileges when they are not using application.

Predicate is other feature which is having additional SQL syntax to restrict the rows returned by the SQL statement. The predicate is at the heart of enforcing the security policy.

Later on Oracle introduced advance version of fine grained access control is VPD and fine grained auditing.

Php Service

PHP, which stands for “Hypertext Preprocessor”, is a server-side, HTML embedded scripting language used to create dynamic Web pages. Much of its syntax is borrowed from C, Java and Perl with some unique features thrown in. The goal of the language is to allow Web developers to write dynamically generated pages quickly.
In an HTML page, PHP code is enclosed within special PHP tags. When a visitor opens the page, the server processes the PHP code and then sends the output (not the PHP code itself) to the visitor’s browser. It means that, unlike JavaScript, you don’t have to worry that someone can steal your PHP script.
PHP offers excellent connectivity to many databases including MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL, and Generic ODBC. The popular PHP-MySQL combination (both are open-source products) is available on almost every UNIX host. Being web-oriented, PHP also contains all the functions to do things on the Internet – connecting to remote servers, checking email via POP3 or IMAP, url encoding, setting cookies, redirecting, etc.

Hypertext Preprocessor is a widely used, general-purpose scripting language that was originally designed for web development to produce dynamic web pages. For this purpose,
PHP code is embedded into the HTML source document and interpreted by a web server with a PHP processor module, which generates the web page document. As a general-purpose programming language, PHP code is processed by an interpreter application in command-linemode performing desired operating system operations and producing program output on its standard output channel. It may also function as a graphical application. PHP is available as a processor for most modern web servers and as a standalone interpreter on most operating systems and computing platforms.
PHP was originally created by Rasmus Lerdorf in 1995 and has been in continuous development ever since. The main implementation of PHP is now produced by the PHP Group and serves as the de facto standard for PHP as there is no formal specification.[3] PHP is free software released under thePHP License.
PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.
Instead of lots of commands to output HTML (as seen in C or Perl), PHP pages contain HTML with embedded code that does “something” (in this case, output “Hi, I’m a PHP script!”). The PHP code is enclosed in special start and end processing instructions that allow you to jump into and out of “PHP mode.”
What distinguishes PHP from something like client-side JavaScript is that the code is executed on the server, generating HTML which is then sent to the client. The client would receive the results of running that script, but would not know what the underlying code was. You can even configure your web server to process all your HTML files with PHP, and then there’s really no way that users can tell what you have up your sleeve.
The best things in using PHP are that it is extremely simple for a newcomer, but offers many advanced features for a professional programmer.
MySQL is a relational database management system (RDBMS) that runs as a server providing multi-user access to a number of databases. The MySQL development project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements. MySQL was owned and sponsored by a single for-profit firm, the Swedish company MySQL AB, now owned by Oracle Corporation.
Members of the MySQL community have created several forks (variations) such as Drizzle, OurDelta, Percona Server, and MariaDB. All of these forks were in progress before the Oracle acquisition; Drizzle was announced eight months before the Sun acquisition.
Free-software projects that require a full-featured database management system often use MySQL. Such projects include (for example)WordPress, phpBB, Drupal and other software built on the LAMP software stack. MySQL is also used in many high-profile, large-scale World Wide Web products, including Wikipedia, Google and Facebook.

MySQL is the world’s most popular open source database software, with over 100 million copies of its software downloaded or distributed throughout it’s history. With its superior speed, reliability, and ease of use, MySQL has become the preferred choice for Web, Web 2.0, SaaS, ISV, Telecom companies and forward-thinking corporate IT Managers because it eliminates the major problems associated with downtime, maintenance and administration for modern, online applications.
Many of the world’s largest and fastest-growing organizations use MySQL to save time and money powering their high-volume Web sites, critical business systems, and packaged software including industry leaders such as Yahoo!, Alcatel-Lucent, Google, Nokia, YouTube, Wikipedia, and Booking.com.
The flagship MySQL offering is MySQL Enterprise, a comprehensive set of production-tested software, proactive monitoring tools, and premium support services available in an affordable annual subscription.
MySQL is a key part of LAMP (Linux, Apache, MySQL, PHP / Perl / Python), the fast-growing open source enterprise software stack. More and more companies are using LAMP as an alternative to expensive proprietary software stacks because of its lower cost and freedom from platform lock-in.
MySQL was originally founded and developed in Sweden by two Swedes and a Finn: David Axmark, Allan Larsson and Michael “Monty” Widenius, who had worked together since the 1980’s. More historical information on MySQL is available on Wikipedia.

Tools in Developing a PHP Code

The most basic level of writing PHP Development codes requires only a text editor and a suitable test environment. The installation of the LAMP (Linux, Apache, MySQL, and PHP) environment can be simplified in any machine whether you are using Windows, Mac, or Linux.

PHP development tools come in different configurations according to enhancements offered by each PHP development company.

Text. A good programmer’s text editor will provide you the tools and formatting you need for even the most complex web applications. This is a program that allows “plain text files” to be edited. It can edit .txt, .html, .php, .cgi, and a whole lot more. Unlike word processing programs, this does not save any formatting or other information except the code itself. Mac and window users can readily edit plain text files for people who are writing codes. Each program varies features from the others like color-text display which makes it easier to notice mistakes, quick code buttons for showing previews, or uploading capabilities.

Integrated Development Environments (IDE). These provide same capabilities as text editors with additional tools. If your code needs a simple VI editor then you can live without a good PHP IDE, however, there are benefits of having one that can make you more productive and obtain quicker results. A specialized PHP IDE organizes your files with advanced code editors. It also has more features such as debugging that set breakpoints and a step by step test of your code; profiling which measures and improves your code performance; integrated web browser that tests your code inside the IDE; and source and database controls.

Frameworks. More often frameworks are used in conjunction with an IDE so they are basically not like the previous approaches. They streamline PHP development of web applications by providing basic structures to build them. They promote rapid application development (RAD) which reduces the repetitive coding amount and helps build more stable applications.

Keeping a suitable testing tool is also essential. While a good PHP Development Companyhas to be well-versed with LAMP, the good news is that a programmer like you doesn’t have to be in order to get an environment running on your computer. If you are running Windows for example, the Linux part is already taken cared of without affecting your Windows environment. This would readily be accessible from the Program Files folder.

After these two simple features, the next ones are more crucial. Some people would write or copy a bunch of codes but don’t have any idea on what to do just in case the code doesn’t work. This is where debugging tools and strategies come in.

Identify any syntax errors in your code. Previously, executing PHP program ceases if there are any errors. However, having a PHP interpreter can do the trick. Run the interpreter to find errors but you may have to fix problems one at a time. Errors become easier to debug as you gain experience working with PHP. Some errors won’t be detected until several lines are already added and you have to work backwards to find out what is missing or erroneous. If problem still remains unresolved then use a debugging package with more sophisticated capabilities or seek advice from a PHP development company.

Choosing and Creating a Database for Your Application

Choosing and Creating a Database for Your Application

Author: Sharath Reddy

The first thing about creating a database is to choose the correct database platform. There are some very popular and efficient database management systems (DBMS) in use today such as the Microsoft SQL Server, Oracle, MySQL, IBM IMS and DB2 among others. The most important thing that needs to be considered while choosing the database is the requirements of the application. If the application is to be built on Microsoft technologies like.NET or ASP.NET, it is better to use Microsoft SQL server for the best performance. On the other hand, if the requirement is to handle huge volumes of simple mathematical transactions, the IBM IMS is a viable solution. However, as is the current trend, most applications on J2EE architecture uses the Oracle database for enhanced performance.

After the correct database is chosen, the next step is to create the database. The procedure to create the database differs according to the DBMS to be used. However, one thing that needs to be kept in mind while creating a database is that it should conform to the ANSI SQL standards.

There are several customizable options available during the creation of a database and its underlying schema, which could be crucial to the application. Therefore it is very important to know the documentation of the DBMS being used in your application. It would help in knowing any advanced parameters which might be helpful in fulfilling the requirements of the application. It is the duty of the Database Administrator (DBA) to choose the correct configuration and settings while creating the database, as these things can impact the performance of the application.

The database can be setup be using the “CREATE DATABASE (database name)” command. It is a good practice to ensure that the SQL syntax is written in capital letters while the variable components are written in small letters. This increases the readability of the statements and can be easily referenced for future. However, even if proper casing is not followed, the SQL statement would give the same result.

After the database is created, one needs to add tables, for which the inter-table relationships need to be properly planned. In most complex applications, major issues occur due to improper planning while creating the database. Once the database is completed, the upper layers of the application can be built on it. The database is the most important component of any application and must be chosen and created with caution.
