ensure that this option is the same as that used in the previous run of the Detector (for which affinity data is to be restored).

vSize of dataspace

The size that you want to use for the data space to store the affinity data collected. The size of the data space is ®xed for a run of the Detector. For information about estimating the size of the data space, see ªEstimating the size of the MVS data space and VSAM ®lesº on page 21.

If the data space becomes full when running, the Detector terminates with abend code AUXB.

If you are saving affinity data, there may be a delay from the time the data space became full until the time the Detector actually terminated.

vTransid pre®x

The pre®x (zero through three characters) of the transactions for which you want to gather affinity data, If you do not specify any characters, affinity data is collected for all transactions. If you specify a valid pre®x (for example, AB_), affinity data is collected for only those transactions with identi®ers starting with the pre®x.

Leading and trailing blanks are ignored, but embedded blanks are treated as an error.

„2… Detect affinity types

Whether or not the Detector is to detect the types of affinities listed.

For more information about restrictions affecting the detection of affinity commands, see ªThe Detector componentº on page 12 and ªAppendix A. Details of what is detectedº on page 65.

„3… Transaction system

WAIT commands are listed as transaction-system affinities, because only half the affinity can be detected. (The other half, an MVS POST command or hand posting, cannot be detected.) You should investigate such affinities further, and, if needed, change the output from the Reporter to create basic affinity transaction groups for them.

„4… Last update by <userid>

The date and time when the options were last updated, and the userid of the user who made the updates.

The date is displayed in the format de®ned by the DATFORM system initialization parameter.

„5… Help

Pressing PF1 for help does not save any changes made; you must press the Enter key to save changes.

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.
