„5… The total number of affinity records in the affinity data VSAM ®les. If the Detector was stopped by CICS crashing, and was in the middle of saving affinity data, this ®gure may be inaccurate. However, the ®gure is corrected the next time the Detector is started.

„6… The date and time when the Detector was last started, data was saved, and a change was made to an affinity table. The date is given in the format speci®ed by the DATFORM system initialization parameter.

„7… The total time that the Detector has been in the running and paused states since it was last started.

„8… The name, and current percentage occupied, of the MVS dataspace being used. (This is not displayed while in STOPPED state.)

„9… The message line used to display diagnostic messages.

„10… The keys that you can use to select functions to affect the operation of the Detector, or to get help information about it. This line displays all possible functions, not all of which are appropriate (or selectable) for a given state of the Detector.

Starting the collection of affinity data

When you can start collecting affinity data

You can start collecting affinity data only when the Detector is currently stopped.

To start collecting affinity data, use one of the methods shown in Table 3.

Table 3. Methods for starting data collection by the Detector

Where used

Command or function key

 

 

Control display, CAFF01

F5 function key „1…

 

 

3270 terminal

CAFF START

 

 

Console

F cicsjob, CAFF START „2…

 

 

Application program

EXEC CICS START TRANSID('CAFF') FROM('START') „3…

 

 

Notes:

„1… If you press the F5 function key of the CAFF01 screen, you are asked to con®rm that you want to start the recording of affinity data.

„2… cicsjob is the name of your CICS startup job.

„3… You can use this command from a program initiated during the third stage of CICS initialization: that is, a program speci®ed in the second part of the PLTPI list for the CICS region. For more information about using PLTPI programs, see the CICS Customization Guide.

Using one of the methods listed in Table 3 causes the Detector to record transaction affinities in the CICS region, until you pause or stop data collection by the Detector. Data is collected for only the affinity types that you have chosen to be detected (by specifying Y for the affinity type on the CAFF02 screen).

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.
