Chapter 6. Running the Reporter

This chapter describes how to run the Reporter that runs as a batch job to produce a report of the affinities found by the Detector. The commands reported on are those listed in ªCommands detected by the Transaction Affinities Utilityº on page 11. For information about interpreting the report output by the Reporter, see ªUsing the affinity reportº on page 47.

You can run the Reporter to produce a report of the affinities found in your CICS region and de®nitions for the basic affinity transaction groups that correspond to the report. The de®nitions for the basic affinity transaction groups are suitable for input to the Builder.

This chapter contains the following information:

Requesting a report from the Reporter

You can request a report from the Reporter by editing and running the job, CAUJCLRP. Before running the CAUJCLRP job, change the following as appropriate:

vThe JOB accounting parameters

vThe PARM parameter of the EXEC statement For example:

REPORT EXEC PGM=CAUREP,PARM=©WORSEN=YES©

[WORSEN={YESNO}]

Specify whether the Reporter is to worsen transaction affinity relations for those affinities where the Detector has not detected at least 10 occurrences. For more information about worsened relations, see ªWorsening of transaction affinities relationsº on page 14.

vThe STEPLIB DD statement

Specify the name of the Transaction Affinities Utility load library where you have installed the Reporter program, CAUREP.

vThe CAUAFF1, CAUAFF2, and CAUAFF3 DD statements

Specify the names of your affinity data VSAM ®les for this CICS region.

Note: Each of the CAUAFF1, CAUAFF2, and CAUAFF3 ®les has a header record specifying the applid of the CICS region that created the record. The Reporter checks these applids against the applid recorded in the CAUCNTL ®le, and proceeds only if all four applids are the same.

vThe CAUCNTL DD statements

Specify the name of your Transaction Affinities Utility control VSAM ®le for this CICS region.

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.
