The following acronyms are used in the Tivoli OMEGAMON XE on z/OS help.
CF Coupling facility. On z/OS, a special logical partition that provides high-speed caching, list processing, and locking functions in a sysplex.
CFRM Coupling Facility Resource Manager. A component of z/OS that provides the services to manage coupling facility resources in a sysplex. This management includes the enforcement of CFRM policies to ensure that the coupling facility and structure requirements are satisfied.
CP Central processor. The part of the computer that contains the sequencing and processing facilities for instruction execution, initial program load, and other machine operations.
CPC Central processor complex. In a z/OS or OS/390 environment, a physical collection of hardware (such as an ES/3090) that consists of main storage, one or more central processors, timers, and channels.
CSECT Control section.
ECB Event control block. A control block used to represent the status of an event.
ESCON(R) Enterprise Systems Connection. A peripheral interface for an Enterprise Systems Architecture/390(R) and zSeries(R) computer. The I/O interface uses ESA/390 logical protocols over a serial interface that configures attached units to a communication fabric.
GRS ring Global resource serialization (GRS) ring. Consists of one or more systems connected to each other by communication links. The links are used to pass information about requests for global resources from one system to another in the complex. Requests are made by passing a message or token, called the ring system authority (RSA) message, between systems in a round-robin or ring fashion.
ICF Integrated Coupling Facility. A processor used by multiple systems to coordinate work. ICFs must be assigned to LPARs that then become coupling facilities.
ICSF Integrated Cryptographic Service Facility. Provides the administrative interface and a large set of application interfaces to the cryptographic coprocessor hardware.
IFA Integrated Facility for Applications. A special type of processor.
IFL Integrated Facility for Linux. A special type of processor.
IRD Intelligent Resource Director. A key feature of the zSeries architecture, which automatically directs resources to priority workloads. IRD gives users the capability of managing resource and workload across z/OS LPARs that are members of a common group called an LPAR cluster. The Intelligent Resource Director is made up of three parts: LPAR CPU Management, Dynamic Channel Path Management (DCM), and Channel Subsystem Priority Queuing (CSSPQ).
RMF Resource Management Facility. An IBM licensed program or optional element of z/OS that measures selected areas of system activity and presents the data collected in the format of printed reports, System Management Facility (SMF) records, or display reports. RMF is used to evaluate system performance and identify reasons for performance problems.
RSA Ring system authority. Requests between systems in a GRS ring system are sent in a round-robin or ring fashion by passing a message or token, called the ring system authority (RSA) message.
SRB Service request block. A unit of work that is scheduled to execute in another address space.
SUP System Utility Processor. A special type of processor. See zIIP.
TCB Task control block. A z/OS control block used to communicate information about tasks, within an address space, that are connected to a z/OS subsystem.
WLM Workload Manager. A z/OS component that prioritizes workloads running on MVS and matches workloads with available resources.
XCF Cross-system coupling facility. A special logical partition that provides high-speed caching, list processing, and locking functions in a sysplex. XCF provides the z/OS coupling services that allow authorized programs on z/OS systems in a multisystem environment to communicate with (send data to and receive data from) authorized programs on other z/OS systems.
zAAP zSeries Application Assist Processor. A special class of assist processor designed to run Java(TM) workloads. For reporting purposes, a zAAP is usually referred to as an Integrated Facility for Applications (IFA).
zIIP System z9 Integrated Information Processor. A special class of assist processor, which handles several types of workloads under DB2. zIIPs are also referred to as System Utility Processors (SUPs) and in Tivoli OMEGAMON XE on z/OS, zIIP data is identified as SUP data.
