Overview

Asynchronous Support Layer library works as a filter between existing ACI libraries (version 3 or later) and the client application, which wants to issue asynchronous ACI calls. Since the native ACI interface is synchronous, a client had to wait for the completion of the request. Now using special programming techniques, developers who want to use ACI in an asynchronous manner can use the Asynchronous Support Layer library of this purpose.

How It Works

In early ACI releases, all programmers using the ACI library, had to consider that any ACI call issued by the application would wait until the work is complete. Now, each incoming request is stored into the shared memory area and each request is executed in forked process.

After the application issues a request, it is given a request ID. The request ID is actually the process ID of the forked child process. The operating system does not allow two processes with the same ID. The request ID ensures the uniqueness of each ID.

After the request is completed, it stores the results in the appropriate location in that shared table and terminates. To retrieve the information back to the client, define a special function that terminates (SIGCHLD) a child process. This routine could also transmit the data into an application internal data buffer and free the entry in the table. Doing this ensures that the entry (process) ID will never be repeated in the shared memory table.

Sadmin Sample Application

For the convenience and ease of understanding the programming techniques required to write the asynchronous ACI applications, the sadmin sample application is provided. This application represents a cut version of the standard dasadmin application. It the following commands:

•mount: mount a volser

•dismount: dismount the volser or force the drive to dismount

•insert: insert volsers

Server specifications

ADIC Server, short for Advanced Data Interoperability and Communication Server, is a modern server platform designed to facilitate seamless data exchanges, interoperability, and communication among various applications and systems. Tailored for organizations that require robust data management solutions, ADIC Server stands out due to its unique features and flexibility.

One of the main features of ADIC Server is its comprehensive data integration capabilities. It supports a wide array of data formats, including JSON, XML, and CSV, allowing organizations to connect diverse data sources effortlessly. This flexibility is critical in a data-driven world, ensuring that businesses can leverage their data regardless of where it resides.

ADIC Server also boasts a rich set of APIs, enabling developers to create custom applications and integrations without extensive overhead. This feature allows businesses to extend their existing systems and ensure that they can adapt their operations quickly to meet ever-changing market demands.

In terms of technology, ADIC Server is built on a microservices architecture, which ensures scalability and reliability. Each microservice can operate independently, allowing organizations to scale specific components of the system according to their needs. This modular approach also promotes resilience, as failure in one service does not directly impact the entire server functionality.

Security is another hallmark of ADIC Server. The platform incorporates advanced encryption protocols and authentication mechanisms to safeguard sensitive data transactions. Role-based access control (RBAC) ensures that data is only accessible to authorized personnel, thus significantly reducing the risk of data breaches.

Another characteristic deserving mention is the server's exceptional performance. ADIC Server is optimized for high throughput and low latency, making it suitable for real-time data processing. Organizations can rely on the server to handle large volumes of data from various sources without compromising speed or efficiency.

Moreover, its user-friendly interface and robust monitoring tools facilitate effective management and troubleshooting. Administrators can easily track performance metrics, identify bottlenecks, and ensure optimal operation of the server.

In conclusion, ADIC Server represents a cutting-edge solution for organizations striving to enhance data interoperability and communication. With its integration capabilities, scalable architecture, security features, and performance optimization, it stands as a dependable choice for businesses looking to leverage their data assets more effectively.
