Oracle Oracle IT Architecture Release
I've begun to movement my enterprise's building and verify databases to an Oracle Multitenant structure. Multitenant...
is never new, having debuted in 2013 with the initial unencumber of Oracle Database 12c, version 18.104.22.168. So, why am I moving to it now?
beneath is an inventory of reasons, starting from conclusion-of-life expertise considerations to easier administration and the capability to install more databases on our current techniques. examine on to look if your firm should consider becoming a member of mine in adopting Oracle Multitenant, which -- for those not already within the know -- enables you to put assorted pluggable databases right into a single container database. believe of Multitenant as virtualization moved to the database level.
Oracle has deprecated the non-Multitenant architecture in 12c. that's right! You can be pressured to circulate to an Oracle Multitenant architecture at some point in the future, notwithstanding there is no frequent plan for a version of Oracle Database during which non-Multitenant configurations will stop to exist. in spite of the fact that you do not want the multi-tenant capabilities now, that you would be able to start getting used to the new method by putting one pluggable database right into a container -- what Oracle calls a single-tenant configuration.
That doesn't suggest you ought to pay for the extra-can charge know-how -- if you most effective have one pluggable database, Oracle Multitenant is free. but when you do wish to run more than one pluggable database in a full multi-tenant architecture, you are going to need to pay the additional licensing charges.
Our VMware atmosphere is approaching conclusion-of-existence. We presently run our construction and verify databases in VMware, licensing Oracle Database on the processors in our Oracle-only VMware ESX cluster. despite the fact, we're running ESXi 5.5, so that it will lose accepted assist in September 2018. We can't upgrade to the newer ESXi 6.0 or above with out being compelled with the aid of Oracle License management functions to license Oracle Database on all processors in all the ESX clusters in our business. Oracle's place is that it be too easy to reside-migrate our digital machines (VMs) to other ESX clusters, so that they need to all be licensed.
while running Oracle on VMware ESX has been tremendous for us, or not it's clear that we can not proceed to do so for the long run. My company must find a different answer and still remain agile in our database infrastructure. running Oracle Multitenant on actual servers can enable us to get rid of VMWare from our Oracle infrastructure, whereas now not handiest holding, but also improving our agility.
Database administration gets less difficult. An Oracle Multitenant architecture forces a big exchange in how database directors (DBAs) strategy their jobs. They need to remember even if certain administrative projects should be performed at the container or pluggable database level. however, once DBAs overcome that researching curve, they may find their time spent administering a database is decreased.
when I began with my company, we had a dozen nonproduction databases. In seven years, that count has grown to greater than 30 databases. but tasks at the container database degree only deserve to be performed as soon as, no remember what number of pluggable databases I have. And projects at the pluggable database level are effortlessly scripted to loop through the entire databases for execution.
we can add extra databases. My enterprise has all the time struggled with the confined variety of databases at our disposal. As I said, I've seen the number of nonproduction databases develop from 12 to more than 30. Our administration would love for us to have much more databases for our utility developers, but we're restrained by using useful resource considerations on the VMware hypervisor host.
with a purpose to spin up yet another VM, we would want more memory -- it's the amount of attainable RAM that appears to be our bottleneck. With our Oracle Multitenant architecture, we will eliminate the overhead of memory and different device elements from every VM. This permits us to deploy much more databases than before with the equal actual hardware.
Clones can also be created more straight away. we have scripts in area to create a database clone. We use disk-based mostly snapshots and clone our multi-terabyte database on the disk storage. We then mount those clone volumes to a VM and open the database.
With our present setup, we will create distinct clones of our construction databases in our digital machines. These clones are used to create check databases and many construction databases which are copies of production.
Oracle Multitenant can clone a pluggable database, however also has the potential to perform a snapshot clone. a daily clone duplicates all the statistics info in a database. This works extraordinary for small databases, but our simple creation database is over 15 TB in dimension.
a daily multi-tenant clone would require duplication of the records data, however a image clone completes in under a minute devoid of duplicating them. Any alterations to the clone outcomes in new blocks on disk; the usual pluggable database uses the usual blocks, whereas the clone receives a duplicate of the exchange block best. This allows for for terribly speedy cloning, whereas also decreasing the disk area necessities.

This sample chapter from e-Business for the Oracle DBA covers capacity planning, using StatsPack for capacity planning purposes, architectural issues and components of an e-Business, and design issues for e-Businesses.
This chapter is from the book
Capacity Planning, Architecture, and Design Issues Essentials
Proper capacity planning can minimize performance problems in the system after it is implemented.
Capacity planning for an e-Business is an art rather than a science because its requirements change all the time.
Oracle8i (release 8.1.6) and higher provide a mechanism called the STATSPACK utility for historical data collection and the capability to translate the data into reports that can show database usage trends.
One key characteristic of a successful e-Business is its capability and willingness to change quickly according to market needs. An even better characteristic is its capability to predict the direction in which the market might shift in the future so that it can prepare in advance to meet the new demands.
The e-Business architecture is better than a straight client/server architecture because the client doesn't stay connected to the database, the application server stays connected only for the time required to make a request and receive the results back from the database server, network traffic is reduced, idle processes do not consume resources, and response time is improved.
When you start to move your systems to an e-Business, it can help to start small and identify a small project that can quickly make the transition and at the same time provide high impact and return on investment (ROI). When this transition is successful, you can build on the experience and feedback from this venture.
An e-Business needs to have a forward-looking application architecture that deals with the following critical requirements:
Integration of intra-business processes
Innovative methods for adding value
Customer- and solution-oriented procedure
Plan for growth and change
In this chapter, we will do the following:
Learn how to perform capacity planning
Learn how to use StatsPack for capacity planning purposes
Examine architectural issues for an e-Business
Examine the architectural components
Look at design issues for e-Businesses
Capacity planning is part of the planning phase. This very important process is completed with the intention of minimizing performance problems with the system after it is implemented. In this sense, capacity planning involves analyzing the same kinds of issues that you would analyze when tuning the system:
How should you choose the system components to use?
What type of architecture is suitable?
What values should be set for the various parameters?
What are the characteristics of the applications?
What are the characteristics of the system?
What business rules are to be implemented?
How much can be forecasted or predicted about the system usage?
What are the system requirements in terms of availability? Scalability? Security? Performance?
Good capacity planning provides a cushion for sudden bursts in load and can tolerate some application inefficiencies.
Capacity planning for an e-Business is an art rather than a science because its requirements change all the time. Its characteristics also change all the time and are difficult to predict. To understand the capacity planning issues with an e-Business such as DOeBIZ.com, you have to understand that it is very difficult in such an environment to have a satisfactory architecture that meets all the requirements well. You should plan for possible extra growth and build a system that has more capacity than current and predicted future needs.
Capacity Planning Questions
Several important questions need to be addressed as part of the capacity planning process:
Generally, scalability is determined in terms of the performance increase relative to additional system components; for example, if one CPU gives a performance of x and adding an extra CPU gives a performance of 1.4x, the scalability is 1.4. This increase is not usually linear because of the overhead associated with coordinating the activity of the additional components. Good capacity planning requires a good understanding of future needs. If you improperly predict future needs, you might be able to satisfy your immediate system needs, but fixing problems due to unforeseen increases or changes of needs would require a lot of effort.
What are the availability requirements? Availability requirements are generally specified as the percentage of time that your system has to be up. Transaction processing e-Commerce sites usually have very high availability requirements. The Internet itself has a reliable built-in capability to route around problems; therefore, when you're looking at high availability solutions, you should look at these elements of your own system:
Disk drives—Consider using a Redundant Array of Inexpensive Disks (RAID) configuration.
Web server hardware—PCs are cheap but not very reliable, whereas mainframes are extremely reliable but very expensive. Therefore, you could use workstations as a compromise for the Web server hardware.
Operating system—Compared to Windows and Macintosh, UNIX systems are much more stable and are better suited for high availability requirements. You might also consider a high-availability OS such as Solaris HA.
Uninterruptible power supply (UPS)—Using a UPS is a necessity.
Clustering solution—You should seriously consider using a UNIX- or NT-based clustering solution.
High availability requirements dictate quick reaction by an iDBA. Therefore, it is very valuable to have an architecture in place that supports automatic notification to an iDBA when performance falls below a certain threshold or when other critical events occur.
What are the budgetary constraints? Money is always an important issue, and you need to ensure that the chosen architecture can provide a high benefit-per-cost ratio. You should also consider the budget for ongoing maintenance and upgrades of the architecture as well as the cost for administration and performance tuning.
Beware of Bottlenecks
When you add extra components to increase capacity, take care to ensure that you are not introducing a bottleneck somewhere by virtue of this system change.
Oracle Database Trend Analysis Using STATSPACK
Proper designing and capacity planning (and later, database tuning) will benefit tremendously if some trend analysis is available for the database usage. Oracle8i (release 8.1.6) and higher provides a mechanism called the STATSPACK utility for historical data collection and the capability to translate the data into reports that can show the database usage trend. Even though Oracle introduces STATSPACK with Oracle 8.1.6, a patch available from Oracle Corporation allows you to use STATSPACK with any Oracle8 database.
The STATSPACK utility is a set of scripts that run a special version of the Oracle BSTAT/ESTAT utilities. Unlike BSTAT/ESTAT, STATSPACK captures performance data and stores it in special Oracle tables with names that have the prefix STATS$. Each STATS$ table is owned by the PERFSTAT user. Note that you can use the regular SQL*Plus DESCRIBE command to determine the columns in the STATS$ table.
DBAs commonly use trend analysis to understand the behavior of the database at various times. This type of analysis also helps in identifying patterns of behavior in terms of database usage. Oracle Enterprise Manager (OEM) provides a capacity planning tool as well, but STATSPACK provides a large number of statistics that can be used to generate different types of trend reports. Here are some useful metrics:
Data buffer hit ratio—This metric gives an idea of the effectiveness of the database buffer cache and the setting of the db_block_buffers parameter.
Physical disk reads and physical disk writes—These metrics give a good idea about the I/O activity in the system.
I/O waits—This metric can be used to determine I/O contention problems and can indicate whether the physical design of the database is good.
Sorts—This metric is an indication of the effectiveness of sort activity.
Buffer busy waits—This metric is an indication of freelist contention and can also indicate concurrent UPDATE or INSERT activity on the same object.
After STATSPACK captures the various performance statistics, you can generate various trend reports using the data gathered. These trend reports would provide signatures for various database metrics. For example, you might observe that on Monday mornings between 8 a.m. and 9 a.m., the I/O activity is extraordinarily high. This knowledge can help in taking the proper actions. In order to forecast the database growth trend properly, you must archive and analyze the data that is collected by any tool such as STATSPACK. The script in Listing 3.1 shows how to plot the average I/O occurring by hour of the day.

Column phyreads format 999,999,999
Column phywrites format 999,999,999

In addition to generating trend reports, you can use queries to generate customized alerts that indicate to the DBA when certain preset thresholds get exceeded. The script in Listing 3.2 can be scheduled to run at set intervals to indicate when the following are true:
Buffer hit ratio < 85%
I/O waits > 2000

This blog post is the second part of "The Definitive Guide to your next PHP framework."
Didn't read it yet? You can check it out here.
The following parts will be published during the next couple of weeks or you can click the link below to download the full version of the Kindle book "The Definitive Guide to your next PHP framework."
If you have read the first part of this article, you should be confident when your colleagues ask you what a framework is and why PHP has so many of them.
If you are new to this topic and you want to scale up your web development skills, or you are a veteran and you would like to explore more choice out there, below you will find several others framework reviews that will let you decide which one to use next.
Table of contents
I need to be honest here, this was the first framework I used, and, as they say, you will never forget your first love.
When I was first introduced to an MVC environment from PHP developers using other frameworks, it was a struggle trying to understand where to put the code, and why there was the need for that extra effort arranging PHP, MySQL, and HTML pages in different parts of the project folder.
Then I discovered CodeIgniter, specifically, I read the first 4-5 pages of its documentation.
Suddenly everything became clear and, in a couple of hours, I was able to recreate functionalities and properly divide up code using the framework, and it helped me a lot when I learned more advanced frameworks.
CodeIgniter is quite old, it released initially in 2006, but, after being taken into the stewardship of the folks at the British Columbia Institute of Technology, it still gets updated often.
In fact, at the time of my writing, the latest version (3.1.8) was released at the end of March 2018.
The most important characteristics of CodeIgniter are the lightness and the speed at which it procesess data.
It's the framework I'll be discussing in this post that looks the least like a framework.
Compared to the other PHP frameworks, CodeIgniter has a clear and easy to understand file structure, very detailed documentation, and lots of users and companies that still use it and can help provide support.
It is definitely the way to go if you feel ready and you have enough experience with vanilla PHP.
With this framework you are ready to take the step further.
Foreword: Drupal is not an actual PHP framework, it is more of an advanced CMS or, even better, a CMF (Content Management Framework).
Drupal was founded in Belgium by Dries Buytaert, who developed a messaging board to stay in touch with his groups of friends.
Its first domain was drop.org and its popularity increased so quickly that in January 2001, he decided to officially launch the website after changing its name to Drupal.
By the way, Drupal means “drop” in Dutch.
Unlike other popular CMSs based on PHP, Drupal requires more time to be fully understood.
It has a bigger learning curve, but the response of several developers was that, after a while, the flow was very smooth.
It runs on the majority of PHP web servers such as Apache, Nginx, and Microsoft IIS.
It also supports the most important databases, like MySQL, MariaDB, PostgreSQL, SQLite, Microsoft SQL Server, Oracle, and MongoDB.
The PHP code is arranged in modules, and they can be enabled and disabled depending on the user choices.
The main module that builds the heart of the framework is called core,
This core can be enlarged by installing the extension developed and available on drupal.org.
Right now for example, there are more than 38000 free modules available, thus everything you need is already there.
Like the backend, even the front-end could be improved and, just like modules, there are several themes that can be enabled.
It's also reliabile. Having been founded almost 20 years ago, there has been a lot of time to improve and create a robust and secure product.
It is also perfect for a wide range of different projects, from websites to blogs and forums to e-commerce and social networks.
They can be scaled out just by adding the necessary modules.
There is also a continually growing community that creates and deploys tons of resources on a daily basis.
In conclusion, it is a very good CMS and if you have time to to learn it, it will be time well invested.
Fat-Free PHP Framework
Fat-Free is a micro-framework created by Bong Costa, a Filipino web developer and consultant.
As you can probably glean from the name, the key to a micro-framework is in its size.
It consists of only the bare minimum code that allows your project to run without adding any unnecessary structure.
There are multiple advantages in using this kind of skeleton.
The weight of the project. In fact, Fat-Free is less than 55kb, and it has a very easy learning curve. For the developer, this means no wasting time learning how things work and so you can put all your time into coding.
Fat-Free requires PHP 5.3 or higher and supports both SQL and NoSQL databases. It also has an ORM built-in.
Among the key features, it allows routing and has a good template engine connected with the views.
Even though there are good reasons to use a micro-framework, you have to consider that this could be seen as a limitation when the project needs to be scaled or if there is more than one web developer working on it.
Another little limitation is that Fat-Free does not come with a defined structure but you need to create it according to your needs, and this could be intricate if at the beginning.
One of the most interesting (in my opinion) PHP frameworks available is Fuel.
It was created by several web developers with lots of years working and building PHP frameworks — Dan Horrigan and Philip Sturgeon (famous for their contributions to CodeIgniter), among them.
Fuel seemed to be a good mixture between CodeIgniter 3.x and Kohana 2.x taking the best parts and improving on each of them.
The result was a very fast structure to work with.
It was designed to have full support of the hierarchical Model View Controller principle, which means that the selected code can be used in several pages across the entire project — just think of a shopping cart or blog posts.
Let's forget the presence of the presentation model, also called ViewModels. It basically adds another level between the views and the controllers.
The idea of the file structure for FuelPHP was copied from Kohana and improved upon, a wise use of namespaces and autoload which allows the calling of class to happen clearly faster than the parents.
It also came with two packages pre-installed, ActiveRecord and Oil, the latter of which is a very useful command line utility.
FuelPHP has been developed by people that surely know what they are doing and it took one of the best features of Kohana (its file structure) and mixed it with CodeIgniter, which, as seen above, has been a masterpiece for a decade.
But now, with the release of PHP 7, it's starting to show its age.
The downside of it may be that the community has never grown that much, thus it is very difficult to find the support and answers to questions from other developers.
Phil Sturgeon was really kind to reply to my email when I asked for information about this framework.
He said that the peak of the effort of the development team was in the years 2011-2012, and even though the code is still available online, the project was officially abandoned in 2015.
He also linked me to a blog post he wrote, dated January 2011, in which he was introducing FuelPHP to the world.
I highlighted what I thought was the most important information above, but if you want to check his post out, here is the link:
Sturgeon's Introducing to Fuel PHP
Another external reference he sent me was a blog post written by Dwayne Charrington, in which he carefully compared the main characteristics of Fuel and CodeIgniter.
Codeigniter vs Fuel PHP
Phil never rests, and he gave me a list of several projects he is currently working on. He is now mainly working at Wework, a New York based company.
Among his projects you can find:
• Speccy • Rails-sunset • Faraday-sunset • We-call
All of them have repositories on GitHub.
He is creating tooling to help users with API specifications and API interactions in general.
Here is a link to a few articles for whoever wants to learn more about the topic.
Another fascinating framework, at least for its composition, is Gyroscope.
Developed by Antradar, it has been around for a while, in fact, its first release is dated to more than 9 years ago.
It supports 5.4 and the newest versions of PHP and, among its pros, there is the size, which is less than 200 KBs and thus, its speed.
Unlike the other frameworks we have just seen, Gyroscope uses anLCHH architecture and not the more popular MCV.
In this architecture, a div tag with a unique id is populated using previously chosen data.
This data invokes the client that sends an AJAX request to the server side. Then the PHP does its stuff like create, delete, etc., and updates the view.
This makes the path equal to an HTTP request which is good for performance and debugging.
Some problems you might encounter if you choose to use Gyroscope is that there is low or no support at all, the documentation in the official website is out-of-date, alongside a community that has never really grown.
My last thought is that if you want to explore more in the PHP world and learn about LCHH, it is fine to give it a shot.
But, at the same time, be aware that there are more advanced frameworks out there.
Released in July 2003, Jamroom is another CMS.
Now in its sixth version, it was developed by Talldude Networks and is licensed with a Mozilla Public License.
Jamroom is a very different product from the others you are seeing here.
It is composed by a Module architecture that permits the structure to increase or decrease its functionality.
The other part of Jamroom is its skin, which allows you to change the features and look of the website.
Everything inside it is either a module or a skin.
A relevant event is the fact that it ran on Flash until version number 5, which carried some issues regarding mobile responsiveness.
Nowadays, the problem has been successfully solved and all the multimedia data uploaded is then converted and available in several formats.
Here is another Content Management Framework.
This is an LGPL licensed project, which means that the external developers can enhance the code by adding and improving implementation and features.
Kajona was created in 2004. The second version was deployed in 2005 immediately followed by the version 2.1 in 2006. At the moment, this CMS is a sound framework arrived at its sixth version.
The system is separated it two main sectors: the backend, which is the part used to maintain the website, and the portal, which is used to show the content.
This portal has built-in in-page editing functionality.When hovering on an editable element it is possible to update its contents and the result will be seen on the fly.
From a web developer’s point of view, the architecture looks like a normal MVC with the three distinct layers.
Kajona supports MySQL, MariaDB, PostgreSQL, Oracle, and SQLite. It also provides a template engine to render the content in the front-end.
To sum up, this is a very solid CMS built in a way that its code can be tweaked and edited in a very smooth way.
It is not mainstream, so you will not find a lot of support, but it comes along with a good documentation.
If you need a similar product and you do not want to use WordPress, it is worth giving a shot.
I have already mentioned this framework when I was describing FuelPHP above.
Kohana was, yes I wrote was, a very good and a very unlucky framework.
Its development started at the end of May 2007, from the plan of some CodeIgniter members and its first name was BlueFlame.
The first official version was released a couple of months later, without any documentation.
After some scrambling by the internal team, the second version was released in November of the same year. At that time it was written in PHP 5.0.
The third and last version of this PHP framework was released officially on September 9, 2009, and the last update, 3.3.6, was released July 25, 2016.
Kohana was formally deprecated on July 1, 2017.
Several intents of revival have been tried, at the moment the closest heir is Koseven.
I have spoken with Chema Garrido. He is the frontman of Koseven and he said that the framework is a compatible replacement of Kohana, which allows users that do not want to migrate for Kohana to keep the application bug-less and up-to-date thanks to post security fixes and compatible with the latest versions of PHP.
He also advised using a more modern product; like me, he is a fan of Laravel, which you will read more about it in the next section.
Here is the showpiece of the list.
From my point of view, Laravel is without any doubt the most interesting framework for PHP.
Its growth and the list of features are simply unbelievable.
Created by Taylor Otwell as an experiment of improving CodeIgniter, Laravel's first release occurred on June 2011.
It wasn't a real MCV because of the lack of controllers but had dozens of internal features such as authentication, sessions, routing, and localization.
Several enhancements were brought by the second version of Laravel, which finally supported controllers, IoC principles, and a blade templating system that permits the developers to better integrate PHP with the view.
Laravel 3 was released in February 2012 and, in a certain wa,y it could be considered a small breakthrough.
Tthe main features are: Artisan, a brand new CLI (command line interface), plus database migration, events handling and bundles, and a packaging system.
In May 2013, Mr. Otwell released Illuminate, the nickname chosen for Laravel 4.
After so many successful years, it was completely rewritten and distributed as a package via Composer.
With the fourth version of Laravel, developers could really certify that the project was now growing at the point to be world class.
Among its new features, I'd like to highlight database seeding, which allows for the populating of databases, support for different kinds of emails, soft deletion, and message queueing. Not to mention the publication of a release scheduled for the minor version.
Basically, from this version on, there will be a new minor version every six months or so.
Laravel 5 made its appearance in March 2015. This version includes Flysystem for remote storage, Elixir to handle package assets, Socialite for authentication, and Scheduler for... guess what? Scheduling tasks!
At this point, Laravel was already the most popular PHP framework.
The first version with long-term support (LTS) was Laravel 5.1. The plan, then brought in again with version 5.5, was to support security and bug fixes respectively for two or three years.
At the point of writing this article, Laravel is on version 5.6 , which was officially been released on February 7, 2018.
Besides the unbelievable high quality and hard work from the creator and the contributors, I think that Laravel changed how web developers write and think about their job.
For example, using a feature like Eloquent ORM (Active Record) presenting database tables as classes makes the developing process, thus the life of developers, so much easier.
Attending Laracon in either the US or Europe is something that most developer have dreamed of at least once.
Laravel News will keep you and your colleagues informed about what is happening around this framework, and last, but not the least, Laracasts with thousands and thousands of minutes of free videos edited by Jeffrey Way, an incredible developer former top-mind at Envato tuts+.
As you can se,e choosing Laravel means choosing the entire ecosystem.
Join a huge community of developers tha,t even if you do not realize it, will make your job better in the years to come.
To Be Continued...
Now It's Your Turn
I hope you enjoyed my framework comparison.
The next part will be published soon.
But now, I want to hear from you:
Which PHP framework has intrigued you the most? Are you going to try one of these listed above?

SAP BusinessObjects BI 4.0 is the culmination of more than one million man-hours of development by SAP. It was released as part of the SAP Ramp-Up program in November 2010 and is expected to be available for general release in the summer of 2011.
When compared with the previous version, 3.1 (released in 2008), there are a number of significant improvements:
The user interface (UI) is totally revised and improved, with Microsoft Office 2007-style toolbars.
The limitations in 3.1 when reporting on SAP NetWeaver BW data have now been lifted. For example, SAP BusinessObjects 4.0 can report on hierarchies.
However, the most significant change in SAP BusinessObjects has been behind the scenes. In BusinessObjects 3.1, different technologies accessed the data for each of the tools (Crystal Reports, Web Intelligence and Xcelsius). Now all the tools use the same BI Consumer Service (BICS) interface to directly connect to SAP NetWeaver BW through high-performance APIs. This results in simpler architecture, reduced development requirements and much better performance.
The release of SAP BusinessObjects 4.0 has led to some common questions in the community. Here are some of the main questions and their answers.
What about BusinessObjects 4.1?
As yet, no date has been announced for the release of BusinessObjects 4.1, which will contain smaller improvements and bug fixes. This will likely be within the next two years.
What is happening to SAP Business Explorer (BEx)?
BEx is SAP's traditional reporting tool for the SAP NetWeaver BW system. It provides interfaces within Web browsers and Microsoft Excel, in addition to tools for producing dashboards and print-ready reports. It has a large user-base and is a satisfactory reporting tool.
Since SAP bought BusinessObjects in 2007, the company has reduced its investment in SAP BEx. The BEx suite is not receiving any major functional improvements, though it did get some minor enhancements in the SAP NetWeaver BW 7.3 release.
Contrary to the popular myth, BEx is not being retired and has no current end of life. According to SAP: “BEx 7.x continues to be delivered with the next SAP NetWeaver BW releases. Currently, there is no planned end of life. The maintenance period is renewed with every major BW release.”
What are the advantages of BusinessObjects over BEx?
BusinessObjects is a huge improvement on BEx, although BEx can be a useful low-cost option. The benefits:
Significantly more reporting options, such as offline reporting. Some reporting options are available in BEx, but only with further customization.
A modern interface, which is intuitive and easier to use.
Improvements to the interface so users are responsible for their reporting, rather than being reliant on IT to build and deliver reports.
However, associated considerations are then
Access to expertise in BusinessObjects is needed
There are potential additional licensing costs
More hardware is required
Another layer added to the reporting architecture, which must then be developed and supported, is necessary
Here are three typical scenarios for organizations and what the release of BusinessObjects 4.0 would mean to them:
Organizations currently using BusinessObjects 3.0 or 3.1 and SAP NetWeaver BW
Any organization that has already made such a commitment to SAP BusinessObjects should plan for an upgrade to 4.0. This requires a technical upgrade and migration of objects to take advantage of the new functionality.
Organizations currently using BEx
Organizations using BEx should consider moving to SAP BusinessObjects 4.0 and reviewing their BI ownership and strategy. This should not be considered a like-for-like implementation, as the way that reports are owned, built and used will be different.
It is notoriously difficult to change the way a business considers and uses its reports, so they may wish to consider a pilot SAP BusinessObjects implementation in an area of the business that doesn’t use BEx reporting. This gives companies a fresh area in which to define and implement a new BI strategy.
Because of the fundamental changes between BusinessObjects 3.1 and 4.0, I strongly recommend that an organization not now implement 3.1. Doing so would commit to an expensive upgrade and migration project when it eventually chooses to move to 4.0 or 4.1.
Organizations currently with no BusinessObjects/BEx installations
SAP BW and BusinessObjects 4.0 is the best combination of systems available, especially when the core ERP is SAP ECC, and will position an organization for many years of reporting.
This comes at a greater licensing expense when compared with implementing SAP NetWeaver BW and BEx, and an organization must decide whether that expense is justified for its purposes.
The SAP NetWeaver BW InfoProvider interfaces are industry standard. Therefore, companies can use other reporting tools to directly access the data held within SAP NetWeaver BW (Oracle OBIEE, for example). However, limitations in reporting functionality, performance and increased development costs may make this impractical and increase the potential for complex licensing issues.
Very few organizations have taken this route, and an absence of reference sites and case studies could make this a risky choice.
