Oracle ADF Development ? a technology pacemaker

For instantly responding to changing business requirements your applications require to be flexible. Development teams will develop these applications fast and at very low cost, following the latest industry standards.In the past Oracle has answered this requirement for flexibility through some tools like Oracle Reports, Oracle Forms and Oracle Designer but the best method to achieve this flexibility while continuing to follow Oracle’s lead is to start moving towards using Oracle Fusion.Oracle Fusion search to unite an organization’s different technologies using web-services. At the centre of the web service implementations and new applications written is the ADF (Application Development Framework) technology. Using ADF one can develop new applications and also expand or replace old ones. Oracle promises to continue being a technological pacemaker.

Oracle’s plans do not contain Forms in a big and creative manner. Oracle ADF development helps Oracle ADF developers to design & develop secure, high performance applications and web services using J2EE for the organization. Oracle ADF development delivers noteworthy productivity gains which provides us the ability to rapidly fulfil business requirements while increasing ROI. For promoting developer productivity enhancement, Oracle ADF development includes tools at every level of MVC pattern. ADF includes a JSR2270-extension at the controller layer which allows the quick connection of business component and model layer business services to observe presentation layer components.This is done in a declarative and meta-data-driven way in Oracle, most of which is automated when a component is dragged & dropped on the page canvas.

ADF faces components are productivity-boosters at the top most layers. There is large number of components. Creating JSF custom component helps to include useful and stable implementations of functionality into standard package, used in various settings. Oracle has done this with ADF faces components and now is doing with ADF rich faces components. Every component of the ADF faces suite contains useful properties for helping Oracle ADF developers the method of using specific component without worrying about writing a lot of code, or preparing frameworks, or instantiating things or any other cost of that type.Oracle ADF developers helps to develop secure and scalable Oracle ADF development applications using J2EE standards like JSF & EJB3, and also Oracle products and technologies that considerably increase the productivity of the developer.

Oracle ADF developers having many years of experience helps in using this framework optimally because of unique knowledge of ADF best practices that are developed with careful study of the framework. ADF practices consist of self-developed standard templates for frequently used functionality and proper use of Java and J2EE capabilities.Best practices and extensive testing guarantees good quality of the code which make application easy to maintain. The code produced by Oracle ADF developers is well documented and when you require to implement new user requirements or when you want to change existing business logic then it becomes easy to modify it.Security is also very much important. Security policies are implemented and everything is fully documented so that you can review it easily.

Customers are provided Oracle consulting services from development & deployment to maintenance & support of the selected enterprise solutions product.

Open MPI is an open-source implementation of MPI and OMPT is the Oracle implementation of MPI. MPI is used for message passing library calls between processes running parallel on different cluster of nodes. OMPT is built version of OMPI optimized for Oracle Solaris 11 which contains development like instrumented versions of MPI libraries.

Following is an example of using OMPT for Oracle Solaris 11:

Obtaining OMPT –

For using OMPT, Oracle Solaris 11 is needed to be installed on the system. Root privileges are needed for running OMPT utilities. For compiling MPI programs, Oracle Solaris Studio 12.1 is required to install. One can install and compile Oracle Solaris Studio on one of the nodes but need to install openmpi-15 package on all the nodes. Openmpi-15 package is hosted by Image Packaging System repository which is required to be configured on the system. Run the pkg publisher command for verifying the configuration of the IPS repository. Configure IPS repository if it is not configured for adding the openmpi-15 package otherwise adding package will fail. The system need to be configured using network access or IPS repository that is provided from the same system. IPS repository is hosted on local host over HTTP. After verifying the configuration of the repository as root, add the Distribution Constructor package by running the pkg install openmpi-15 command. From the IPS repository openmpi-15 package is downloaded and installed immediately.

Listing 1: Output of the pkg install openmpi-15 command

root@solaris:~# pkg install openmpi-15

As shown in the above listing, the pkg install openmpi-15 command shows the status of the process so that progress can be observed easily. After installing openmpi-15 package, include /usr/openmpi/ompi-15/bin in the PATH variable and then it is best to move forward.

Compiling MPI program with OMPT –

To compile MPI programs with OMPT use compiler wrappers or directly call the compilers. First method is more preferred due to library, include, run paths required to be included. The wrappers pass through all options so we require replacing all instances of a compiler in a make file with the utilities of the wrapper. We can compile with one-line command or two phase link and compile. Instead of using wrappers if one needs to directly execute the compilers then one can determine the options used by wrappers.

Running MPI program with OMPT –

Run the program as a singleton after executable is compiled and linked with OMPT libraries. Then program will call appropriate MPI APIs to spawn other processes for the MPI job. Use mpirun utility if you need to create MPI job with multiple processes.

What are the benefits of using the Oracle Ebusiness suite?

Automation in business was not too long ago viewed as a novel idea and many a business adopted it in a piecemeal manner. Often, various functions of the business were kept separate and the data was stored in separate computers operated by different departments. This kind of fractionalization was however costly to such businesses because it often took too long to make minor decisions and a lot of manpower was required to maintain the various databases. All this changed with the arrival of the Oracle Ebusiness suite.
The Oracle Ebusiness suite is a collection of software applications that are designed to carry out different functions within the same business thus allowing the business to do Enterprise Resource Planning, or ERP in short. Its difference with automation, and which is the main advantage of the new system, is that all the business data is stored in a single database and all the functions are carried out from this database. Better still, the business does not need to buy and install the entire Oracle Ebusiness suite simply because it can be accessed remotely. The business can also select the various functions it requires and secure the licenses for using them.
Businesses which use ERP e-business tools enjoy significant benefits. The system comprises of several modules and sub modules, each of which represents a particular business component. If data is entered into one module all the related modules are automatically updated as well. If, for instance, a transaction is entered in the sales module the related modules like inventory and receivables are also updated to this effect. This eliminates the need for reentering the same data several times, and which minimizes errors like multiple entries and loss of important data.
This system is especially beneficial to global businesses that have operations in different parts of the world using different languages, currencies and accounting standards. All these factors can be incorporated into the ERP system thus allowing for seamless integration. Providers of ERP solutions can also quickly update their systems based on emerging business trends and technologies.
Another benefit of the Oracle Ebusiness suite for ERP is that it has planning and simulation functions, and which help in forecasting and decision making. Since all the data is synchronized, business executives can easily use the system to make predictions and come up with appropriate ways of utilizing resources. ERP also helps in improving efficiency and productivity. This is because apart from helping with planning and resource allocation, it also helps with day to day business activities such as timely shipping of orders, inventory management and payment of contractors, among others. It also reduces turnaround times significantly.
Additionally, the business will benefit from ERP because of the standardization of procedures that comes with it. Departmental idiosyncrasies and time-wasting bureaucracy can be effectively eliminated because the whole business is integrated and more efficient. ERP gives the management access to all aspects of the business and thus helps to ensure greater control and to minimize vices such as theft and accounting fraud.

Improve Oracle Database Performance using Data File Striping

While disk level striping greatly benefits many Oracle databases, Oracle databases require striping at a more granular level. Unless we can stripe in sizes of less than the cylinder size for the disk, the disk will have seek contention as the read-write head moves between the cylinders.  In an ideal world, we want to have only a single hot spot on each disk. Carving several hot tablespaces across a small number of disks would create a situation where the roving hot spots would move between the disks, creating an I/O bottleneck whenever two or more hot spots reside on the same spindle. The goal is to have the active Oracle blocks residing on the same cylinder or at worst, closely adjacent cylinders to minimize seek delay on the disk device.

Also, beware that improper file striping may cause collisions when the hot spots converge on a single disk. Striping an application tablespace at the filesystem or Oracle level may create a situation where hot spots migrate across spindles, causing I/O bottlenecks whenever hot spots appear on the same spindle.

If disk cost is not a consideration, each hot application or ERP tablespace should reside entirely on a single spindle. Unfortunately, commercial disks are getting larger every year, and it is very difficult to find small disk devices that contain less than 3 gigabytes of storage. Another problem with all forms of striping is the lack of availability of small disk spindles. Just 10 years ago, the storage disk was considered huge at 1 gigabyte of storage. Today, it is hard to find disks smaller than 8 gigabytes. The larger disks mean that there are fewer disk spindles, and fewer opportunities for striping. Since it is often not possible to isolate ERP tablespaces on separate disks without wasting a huge amount of disk space, the Oracle Administrator must balance active with inactive ERP tablespace across his or her disks.

Although most Oracle DBA associate the striping technique with very large tables, a small, but very active, ERP table will experience relief from bugger busy waits by striping. This technique can be very useful for small ERP reference tables that are simultaneously updated by many transactions. The tables are characterized by a relatively small number of rows with a small row length. Because of the large amount of updating, these tables will experience buffer busy waits, even though the data blocks are already in the database buffer cache.

Therefore, table striping is the best option to avoid physical disk I/O contention as well as it is improving performance bottleneck of your ERP application database.
