Displaying the Detector control screen

To display the control screen that you can use to run the Detector at a CICS

terminal, ®rst type the transaction identi®er CAFF, then press Enter. In response, the Detector control screen, CAFF01 (shown in Figure 6), is displayed. You can use this screen to review and change the state of the Detector, or to display the Detector options screen, CAFF02 (shown in Figure 7 on page 36).

To refresh the values displayed on the screen at any time, press Enter.

To leave the Detector control screen, press the F3 (or F12) function key. This does not affect the state of the Detector.

Figure 6. Detector control screen, CAFF01

 

The Detector control screen, CAFF01, shows the following:

 

„1… The functions that you can select from this state of the Detector. For any state

 

of the Detector, only appropriate functions are displayed.

 

„2… The current state of the Detector. If the state is STOPPED, the display shows

 

the reason why it was stopped.

 

Notes:

 

1. When you stop the Detector, the CAFF state changes to STOPPED only after

 

the Detector has saved the affinity data.

 

2. When you pause the Detector, the CAFF state changes to PAUSED before the

 

Detector saves the affinity data (to ensure that the Detector pauses

 

immediately). After the state has changed to PAUSED, you can refresh the data

 

displayed by pressing Enter.

 

„3… The number of times that the Detector has been paused, and the number of

 

times data has been saved, since the last time that it was started.

„4… The number of new records and updates to existing records written to the

affinity data VSAM ®les when data was last saved.

OS specifications

IBM OS, or IBM Operating System, refers to a family of operating systems developed by IBM to support its hardware architectures. IBM has produced a range of OS versions tailored for different computing needs, such as mainframes, servers, and personal computers. Among the most notable operating systems in IBM's portfolio are OS/2, z/OS, and AIX, representing a blend of innovation and reliability that has defined IBM's reputation in the computing world.

One of the defining features of IBM OS is its robust multitasking capabilities. Both z/OS, predominantly used in IBM's mainframe environments, and AIX, the Unix-based system for IBM Power Systems, support multiple users and processes simultaneously. This ability allows organizations to run numerous applications in parallel efficiently, maximizing resource utilization and improving productivity.

In terms of security, IBM OS incorporates advanced features aimed at protecting data and maintaining integrity. z/OS offers multifactor authentication, data encryption, and a security model that adheres to the latest regulatory requirements. AIX provides Secure Virtualization, which enhances isolation and security in cloud environments, essential for enterprises handling sensitive information.

Another key characteristic is the adaptability of IBM OS to modern technologies. For instance, z/OS is designed to integrate with cloud computing, open source, and DevOps practices. This adaptability supports organizations in modernizing their infrastructure while retaining the stability associated with IBM solutions. AIX similarly supports containerization and virtualization, which are critical for optimizing resource usage in dynamic computing environments.

IBM's commitment to scalability is evident across its OS offerings. Organizations leveraging z/OS can handle enormous workloads and transactional volumes, making it a preferred choice for industries like finance and telecommunications. AIX also supports scalability, allowing businesses to expand their computing resources as demands grow without significant downtime.

The availability of development tools and environments is another noteworthy aspect of IBM OS. With robust IDEs and programming languages support, developers can create and deploy applications smoothly. This assists businesses in streamlining their development processes and improving time-to-market for innovative solutions.

In summary, IBM OS encompasses a suite of operating systems characterized by multitasking, security, adaptability to modern technologies, scalability, and comprehensive development support. These features have cemented IBM's position as a leader in enterprise solutions, allowing organizations across various industries to thrive in an increasingly digital world.
