Sysplex Interview Questions Sysplex |
| MOTCLE | ABBREVIATION | DESCRIPTION |
| base sysplex | The set of one or more z/OS systems that is given a cross-system coupling facility (XCF) name and in which the authorized programs can then use XCF coupling services. A base sysplex does not include a coupling facility. See also Parallel Sysplex | |
| Geographically Dispersed Parallel Sysplex | GDPS | An application that integrates Parallel Sysplex technology and remote copy technology to enhance application availability and improve disaster recovery. GDPS topology is a Parallel Sysplex cluster spread across two sites, with all critical data mirrored between the sites. GDPS manages the remote copy configuration and storage subsystems automates Parallel Sysplex operational tasks and automates failure recovery from a single point of control |
| Geographically Dispersed Parallel Sysplex | See GDPS. | |
| multisystem sysplex | A sysplex in which two or more MVS images can be initialized as part of the sysplex | |
| multisystem sysplex | A sysplex in which two or more z/OS images are allowed to be initialized as part of the sysplex | |
| Parallel Sysplex | (1) A set of z/OS systems that communicate and cooperate with each other through multisystem hardware components and software services to process customer workloads. See also base sysplex (2) A sysplex that uses one or more coupling facilities | |
| Parallel Sysplex | A sysplex that uses one or more coupling facilities | |
| Parallel sysplex | Architecture cum bundle of products announced April 1994 which allows parallel transaction processing in an ES/9000 sysplex. Provides resource sharing, workload balancing and continuous availability. Initially supported up to 32 z/OS systems, presenting them as a single systems image known as a cluster. Major hardware pieces are the Coupling Facility, Sysplex Timer and links to them both. CICS and IMS TM are just two of the software products that needed changes. More recent software has been developed with parallel sysplex in mind, including IRD, Coupling Facility Structure Sizer Tool and the Web-based Parallel Sysplex Configuration Assistant that sets up the initial JCL, procedures and parameters for parallel sysplex. Most parallel sysplexes begin as a single system cluster, with all the parallel sysplex pieces in place. More recently, the architecture has been expanded into the Geographically Dispersed Parallel Sysplex (GDPS). See also CICSplex, ClusterProven. | |

| Plex | Abbreviation for Sysplex. | |
| single-system sysplex | A sysplex in which only one system can be initialized as part of the sysplex. In a single-system sysplex, cross-system coupling facility (XCF) provides XCF services on the system, but does not provide signaling services between MVS systems | |
| single-system sysplex | A sysplex in which only one z/OS system is allowed to be initialized as part of the sysplex. In a single-system sysplex, XCF provides XCF services on the system but does not provide signalling services between z/OS systems. See multisystem sysplex | |
| sysplex | A set of z/OS systems that communicate with each other through certain multisystem hardware components and software services. See also base sysplex | |
| sysplex | A set of z/OS systems that communicate with each other through certain multisystem hardware components and software services | |
| sysplex | A set of z/OS systems communicating and cooperating with each other through certain multisystem hardware components and software services to process customer workloads. See Parallel Sysplex | |
| Sysplex | System complex. A processor complex formed by loosely coupling System/390 processors together into a single unit (using channel-to-channel adapters or ESCON / FICON fiber optic links) the processors are synchronized using the Sysplex Timer , and can be managed as a single system image ( SSI ). Storage (main and Expanded) may be shared among the processors in the sysplex. GRS and XCF are pre-requisites. Note that a sysplex is not primarily a way of building more powerful processors ? it?s a way of building more manageable and resilient processor configurations initially the main uses of the sysplex were for hot standby, and batch workload balancing.
