TS commands

 

v The affinity here is between all transactions that use the same TS queue. It

 

applies to both MAIN and AUXILIARY TS. The match is made on the name of

 

the TS queue.

v The affinity relation can be GLOBAL, BAPPL, LUNAME, or USERID.

v Lifetime can be PCONV, LOGON, SIGNON, ACTIVITY, PROCESS,SYSTEM, and

 

PERMANENT. A MAIN queue cannot be recovered, regardless of de®nition, so

 

cannot cause PERMANENT.

 

v No data is collected if a TS queue is de®ned as remote or if a remote SYSID is

 

speci®ed on the TS command. In such cases, the request is satis®ed by a

 

remote CICS region or by a temporary storage pool in the coupling facility.

 

v Commands in error are treated in the same way as commands that give a

 

NORMAL response, so data is collected.

 

v If a TS queue is created and deleted within the same task, no data is collected.

 

Scanner differences: Scanner detects all instances of TS commands.

LOAD HOLD/RELEASE

 

v The affinity here is between all transactions that LOAD HOLD and RELEASE the

 

same program (or, more probably, table). The match is made on the program

 

name.

 

v The LOAD and RELEASE protocol applies only to programs that are de®ned with

 

RELOAD(NO). If the Detector can not establish the RELOAD attribute for some

 

reason, RELOAD(NO) is assumed.

 

v Once a LOAD HOLD has occurred for a program, any subsequent LOAD (with or

 

without HOLD) or RELEASE is part of the affinity.

v The affinity relation is GLOBAL or BAPPL.

 

v Lifetime is always SYSTEM.

 

v Commands in error are treated in the same way as commands that give a

 

NORMAL response, so data is collected.

 

v LOAD with no HOLD for programs de®ned as RESIDENT is not treated as an

 

affinity because relying on residency for sharing is inherently unsafe, the program

 

can be replaced by SET PROG() NEWCOPY.

 

v The incorrect use of RELEASE for a program de®ned with RELOAD(YES) is not

 

detected.

 

Scanner differences: Scanner detects all instances of LOAD, not just LOAD HOLD,

 

and all instances of RELEASE.

RETRIEVE WAIT/START

vThe affinity here is between all the transactions that issue START commands for a particular transaction at a terminal, where that transaction issues RETRIEVE WAIT. The transaction that issues the RETRIEVE WAIT is also part of the affinity. The match is made on the transid.

vThe affinity relation can be GLOBAL or USERID.

vLifetime can be SYSTEM or PERMANENT. PERMANENT is assumed if PROTECT is speci®ed on any START.

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.
