Oracle 18C ASM: The New Weapon for Data Management

Oracle 18C ASM is a powerful tool for managing data, helping organizations to achieve high performance, reliability, and scalability. ASM stands for Automatic Storage Management, which is a feature of the Oracle database that manages the storage of data across a cluster of nodes. ASM simplifies the storage management process, allowing users to easily manage storage resources across many disks and servers.

Traditionally, the process of managing data in a database involved a complex and time-consuming process of balancing data across multiple disks, servers, and storage vendors. This led to a high degree of complexity in managing data resources, and many organizations struggled to keep up with the pace of data growth.

With Oracle 18C ASM, organizations can easily manage their storage resources in a centralized, automated way. ASM handles all disk and storage management tasks, including allocating space, managing disk flures, and balancing data. This makes it easy for users to manage their data resources, and also reduces the risk of data loss due to hardware flure.

One of the key advantages of Oracle 18C ASM is its ability to scale seamlessly. Users can add disks or servers to the system as needed, and ASM will automatically configure and manage the storage resources. This makes it easy for organizations to keep up with the demands of data growth, and also makes it easy to scale resources up or down based on changing needs.

Oracle 18C ASM also provides a high degree of resilience and reliability. The system is designed to handle disk flures and other issues, ensuring that data is always avlable when it is needed. In addition, ASM provides a high degree of performance optimization, allowing applications to access data quickly and efficiently.

Another advantage of Oracle 18C ASM is its ease of use. The system is designed to be user-friendly, with a graphical user interface that makes it easy to manage storage resources. Users can also access ASM through the command line interface, allowing for more granular control over storage resources.

Overall, Oracle 18C ASM is a powerful tool for managing data, providing organizations with a centralized, automated solution for storage management. With its ability to scale seamlessly, its high degree of resilience and reliability, and its ease of use, ASM is a valuable resource for any organization looking to manage its data resources more effectively. To get started with ASM, check out Oracle’s documentation and tutorials, or speak with a knowledgeable Oracle partner or consultant.

Example Code:

CREATE DISKGROUP data NORMAL REDUNDANCY

FLGROUP f1 DISK ‘ORCL:DATA01′,’ORCL:DATA02’, ‘ORCL:DATA03’

FLGROUP f2 DISK ‘ORCL:DATA04′,’ORCL:DATA05’, ‘ORCL:DATA06’

ATTRIBUTE ‘au_size’=’1M’

ATTRIBUTE ‘compatible.asm’=’18.1.0’

ATTRIBUTE ‘compatible.rdbms’=’18.1.0’;

This code creates a disk group with three flure groups, each contning three disks. The AU size is set to 1 MB, and the compatibility level is set to 18.1.0 for both ASM and the RDBMS. This creates a robust and efficient storage solution that can handle hardware flures and scale as needed.
