(1) A modifier that makes a name unique.<br />(2) Each component name in a qualified name other than the right-most name. For example, TREE and FRUIT are qualifiers in TREE.FRUIT.APPLE.<br />(3) A value that provides additional information about a class, association, indication, method, method parameter, instance, property, or reference.<br />(4) A simple element that gives another generic compound or simple element a specific meaning. Qualifiers are used in mapping single or multiple occurrences. A qualifier can also be used to denote the namespace used to interpret the second part of the name, usually referred to as the ID.<br />(5) When referring to a QMF object, the part of the name that identifies the owner or the location of an object. When referring to a TSO data set, any part of the name that is separated from the rest of the name by periods. For example, 'TCK', 'XYZ', and 'QUERY' are all qualifiers in the data set name 'TCK.XYZ.QUERY'.

(1) A collection of complete systems that work together to provide a single, unified computing capability.<br />(2) In SNA, a group of stations that consist of a controller (cluster controller) and the workstations attached to it.<br />(3) In high-availability cluster multiprocessing (HACMP), a set of independent systems (called nodes) that are organized into a network for the purpose of sharing resources and communicating with each other.<br />(4) In WebSphere MQ, a group of two or more queue managers on one or more computers, providing automatic interconnection, and allowing queues to be shared amongst them for load balancing and redundancy.<br />(5) In Microsoft Cluster Server, a group of computers, connected together and configured in such a way that, if one fails, MSCS performs a failover, transferring the state data of applications from the failing computer to another computer in the cluster and reinitiating their operation there.<br />(6) A data set defined to VSAM. A cluster can be a key-sequenced data set, an entry-sequenced data set, or a relative record data set.<br />(7) A group of application servers that collaborates for the purposes of workload balancing and failover.<br />(8) A group of two or more Domino servers that provides users with constant access to data, balances the workload among servers, improves server performance, and maintains performance when the size of an enterprise increases.<br />(9) A loosely coupled collection of independent systems (or nodes) organized into a network for the purpose of sharing resources and communicating with each other. See also GPFS cluster.
Industry:Software
(1) A network authentication protocol that is designed to provide strong authentication for client/server applications by using secret-key cryptography. See also Kerberos ticket.<br />(2) A network authentication protocol that is based on symmetric key cryptography. Kerberos assigns a unique key, called a ticket, to each user who logs on to the network. The ticket is embedded in messages that are sent over the network. The receiver of a message uses the ticket to authenticate the sender.
Industry:Software
(1) A network divided into smaller independent subgroups, which still are interconnected.<br />(2) To divide a network into smaller interconnected, but independent subgroups.
Industry:Software
(1) A Northern Telecom switch.<br />(2) The custom ISDN protocol implemented on the DMS100 switch, providing 23 B-channels and a D-channel over a T1 trunk.
Industry:Software
(1) A number shown as an optional sign followed by one or more digits and a decimal point, which may be at the end.<br />(2) A numeric constant shown as an optional sign, followed by the letter D or E, followed by a 1- to 3-digit integer constant. For example, 3E-02, which is 3 times 10 to the -2 power or 0.03.
Industry:Software
(1) A number containing a decimal point, an exponent, or both a decimal point and an exponent. The exponent contains an "e" or "E," an optional sign (+ or -), and one or more digits (0 through 9).<br />(2) A constant representing a non-integral number.
Industry:Software
(1) A collection of related and connected CICS regions, which helps to address the inefficiencies in having multiple, full-function CICS systems processing a single OLTP workload. See also multiregion operation.<br />(2) The largest set of CICS regions, or systems, to be manipulated by CICSPlex SM as a single entity. CICS systems in a CICSplex being managed by CICSPlex SM do not need to be connected to each other.
Industry:Software
(1) A coordinated commitment control process between communicating transactions that ensures that all logically-related updates to recoverable resources are completed or that all are backed out.<br />(2) The cross-site mirroring (XSM) processing that copies data from the production copy to the mirror copy.<br />(3) In Unified Modeling Language (UML), the visual representation of the forks and joins representing parallel workflows. Synchronizations enable you to see a simultaneous workflow in an activity diagram or state chart diagram.<br />(4) The process by which a satellite downloads and runs the same DB2 database commands, operating system commands, and SQL statements from the satellite control server as the other members of its group download and then reports the results to the satellite control server.
