This article mainly explains "what is the method of cloud migration of Oracle database". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what is the method of cloud migration of Oracle database".

Like other software development projects, database migration requires careful planning and good practices to ensure its success. Among them, the design of database is very important, especially the schema design of relational database.

What are the methods of cloud migration of Oracle database

During Oracle database migration, certain changes are required, and the result is a series of database schema consolidation. The key to database design adjustment is to have a clear understanding of the entire life cycle of the migration project and to know what is the key work in each step. There are many factors in this design, such as the relevant IT technicians, the tools needed, the mastery of the technology of the source database and target database platform, and the actual project planning. Therefore, before we carry out the migration project, we must have a complete grasp of the above factors, so that we can get twice the result with half the effort and avoid unnecessary trouble to a certain extent.

Database migration options

Database migration is the most common among all Cpact S application migration projects, which allows users to migrate to a new platform without affecting the integrity of the application and without changing existing functions and business roles, including the programming language used in application development. This is the easiest way to migrate and ensures business continuity in the new environment. Another situation involves changes to applications, where applications are difficult to maintain or upgrade in a new environment, either in a new language or with the latest technologies and standards. Such a migration project is more than just a platform migration. For those critical business applications, you need to make sure that they can be accessed in a variety of ways, such as browsers, mobile devices, etc., in which case the application is often adjusted to adapt to the new database environment. A series of simulation tests have to be done before the migration.

Legacy applications on IBM mainframes and other platforms often need to be reorganized to run on distributed platforms. You can use some software to simulate the IBM mainframe environment and test whether it can provide the same functionality, such as Oracle Tuxedo.

Which migration option you choose will depend on your business needs and limitations (such as time, cost, feasibility, etc.). The simplest migration option is to service the existing application Web so that it can interact with other applications on Web or in the cloud. Of course, this approach also needs to be modified through a third-party solution or local functionality to complete the Web service, and the modification will not be large-scale. Even if an application is written in VB or PowerBuilder and cannot be accessed through the network, it can be implemented with some modifications. Nor does it need to modify every program that makes up the application, only those that provide important reusable business services. Migrating database platforms and redeploying applications to new platforms are very popular because they are easy to implement and the fastest. On the other hand, the way it involves rewriting or rearchitecting applications is something that no one wants to see, and such a migration is time-consuming and laborious.

Recently, some new technologies have been born to provide database transparency for applications. These technologies basically allow users to capture database calls made by the application and then translate them in real time to execute against the target database. The purpose of this is to greatly reduce the application changes caused by database migration. However, enterprises need to conduct rigorous tests on the performance of these technologies and the accuracy of SQL statements to prevent problems in critical business environments. Some database vendors are trumpeting these technology products, saying that using them can control database migration projects in the shortest possible time. Users need to be reminded here that these technologies do play a role in database migration, but only for large migration projects, while some smaller projects do not need to use these new technologies at all.

Thank you for reading, the above is the content of "what is the method of cloud migration of Oracle database". After the study of this article, I believe you have a deeper understanding of what the method of cloud migration of Oracle database is, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
