Converting an Oracle 12c non-CDB database to a CDB multitenant architecture can be a complex process, but with the right steps, it can be accomplished smoothly. Initially, it is essential to understand the benefits of using a multitenant architecture, which includes improved resource utilization, reduced costs, and enhanced security. Meanwhile, database administrators must carefully evaluate their current infrastructure to determine if a conversion is necessary.

Moreover, before initiating the conversion process, it is crucial to ensure that the Oracle 12c database is compatible with the multitenant architecture. Consequently, this involves checking the database version, patch level, and configuration. Furthermore, database administrators should also review the official Oracle documentation to understand the specific requirements for the conversion process.

However, once the compatibility checks are complete, the next step is to prepare the database for conversion. Notably, this involves creating a backup of the database, as well as ensuring that all necessary patches are applied. Additionally, database administrators should also consider the overall performance of the database, as this can impact the conversion process. Meanwhile, it is also essential to evaluate the storage requirements for the multitenant architecture, as this can vary depending on the specific needs of the database.

Meanwhile, the actual conversion process involves several steps, including creating a new CDB, plugging the non-CDB database into the CDB, and configuring the multitenant architecture. Consequently, this requires a deep understanding of Oracle 12c and the multitenant architecture. Nevertheless, with the right expertise and planning, the conversion process can be completed successfully.

Preparing the Database for Conversion

Preparation is key when it comes to converting an Oracle 12c non-CDB database to a CDB multitenant architecture. Initially, this involves creating a backup of the database to ensure that all data is safe in case any issues arise during the conversion process. Furthermore, database administrators should also ensure that all necessary patches are applied to the database, as this can impact the conversion process.

Moreover, it is also essential to evaluate the overall performance of the database, as this can impact the conversion process. Meanwhile, database administrators should also consider the storage requirements for the multitenant architecture, as this can vary depending on the specific needs of the database. However, by carefully evaluating these factors, database administrators can ensure a smooth conversion process.

Concurrently, database administrators should also review the official Oracle documentation to understand the specific requirements for the conversion process. Nevertheless, with the right planning and expertise, the conversion process can be completed successfully.

The Conversion Process

However, the actual conversion process involves several steps, including creating a new CDB, plugging the non-CDB database into the CDB, and configuring the multitenant architecture. Meanwhile, this requires a deep understanding of Oracle 12c and the multitenant architecture.

Moreover, the following steps outline the conversion process:

• Create a new CDB using the
  CREATE DATABASE

  command

• Plug the non-CDB database into the CDB using the
  DBMS_PDB

  package

• Configure the multitenant architecture, including setting up the PDBs and the root container
• Test the multitenant architecture to ensure that it is working correctly

Consequently, these steps require careful planning and execution to ensure a successful conversion. Nevertheless, with the right expertise and planning, the conversion process can be completed successfully.

Meanwhile, the following example illustrates the conversion process:

Initially, this example creates a new CDB using the

command. However, the actual conversion process involves several additional steps, including plugging the non-CDB database into the CDB and configuring the multitenant architecture.

Benefits of Using a Multitenant Architecture

However, one of the primary benefits of using a multitenant architecture is improved resource utilization. Consequently, this allows multiple databases to share the same resources, reducing costs and improving efficiency. Moreover, the multitenant architecture also provides enhanced security, as each PDB has its own secure environment.

Meanwhile, the following are some of the key benefits of using a multitenant architecture:

• Improved resource utilization
• Enhanced security
• Reduced costs
• Improved scalability
• Simplified management

Consequently, these benefits make the multitenant architecture an attractive option for many organizations. Nevertheless, the conversion process can be complex, and it is essential to have the right expertise and planning to ensure a successful conversion.

However, if you are considering converting your Oracle 12c non-CDB database to a CDB multitenant architecture, it is essential to carefully evaluate your options and plan carefully. Meanwhile, you may also want to consider consulting with a professional services organization, such as PersonIT, to ensure a smooth and successful conversion.

Initially, a successful conversion requires careful planning and execution. Consequently, it is essential to have the right expertise and planning to ensure a successful conversion. Nevertheless, with the right expertise and planning, the conversion process can be completed successfully, and the benefits of using a multitenant architecture can be realized.

Conclusion

Converting an Oracle 12c non-CDB database to a CDB multitenant architecture can be a complex process, but with the right steps, it can be accomplished smoothly. Meanwhile, the benefits of using a multitenant architecture, including improved resource utilization, enhanced security, and reduced costs, make it an attractive option for many organizations.
