Each time the Detector is started, a new data space is created. For help with calculating the likely data space storage requirement, see ªEstimating the size of the MVS data space and VSAM ®lesº on page 21. You specify this size on the Detector options screen, CAFF02. You can also specify that data from affinity data VSAM ®les (for example, from previous Transaction Affinities Utility runs) is to be loaded into the data space when it is created. For more information about the CAFF02 options screen, see ªChanging the Detector optionsº on page 36.

Note: If there are a large number of data records to be loaded into the data space when it is created (for example, from previous Transaction Affinities Utility runs), the CAFF screen may be frozen for some appreciable time, until the records have been loaded.

Pausing the collection of affinity data

When you can pause affinity data collection

You can pause the collection of affinity data only when the Detector is currently running.

To pause the collection of affinity data, use one of the methods shown in Table 4.

Table 4. Methods for pausing data collection by the Detector

Where used

Command or function key

 

 

Control display, CAFF01

F7 function key

 

 

3270 terminal

CAFF PAUSE

 

 

Console

F cicsjob, CAFF PAUSE „1…

 

 

Application program

EXEC CICS START TRANSID('CAFF') FROM('PAUSE')

 

 

Note:

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

Using one of the methods listed in Table 4 causes the Detector to stop collecting data until you are ready to resume. The data already collected remains in the data space, and can be saved to the affinity data VSAM ®les when the Detector is paused. (You can specify that data be saved when the Detector is paused on the CAFF02 options screen, as described in ªChanging the Detector optionsº on page 36.)

Resuming the collection of affinity data

When you can resume collecting affinity data

You can resume collecting affinity data only when the Detector is currently paused.

To resume collecting affinity data, use one of the methods shown in Table 5 on page 35.

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.
