Sometimes referred to as “Big Blue” IBM is a multinational corporation headquartered in Armonk, New York. It manufactures computer hardware and software and provides information technology and services.
(1) A process that allows the user to represent some form of data as an Object in memory.<br />(2) A Java class that converts a stream of native data to a business object during inbound processing, and converts a business object to a stream of native data during outbound processing. See also custom data binding.
Industry:Software
(1) A data element or variable that holds the address of a data object or a function.<br />(2) The symbol shown on a display or window that a user can move with a pointing device, such as a mouse.<br />(3) See reference.
Industry:Software
(1) A process that does not require operator intervention but can be run by the computer while the workstation is used to do other work. See also foreground process.<br />(2) In the AIX operating system, a mode of program execution in which the shell does not wait for program completion before prompting the user for another command.
Industry:Software
(1) A data item used for storing numbers or number representations in a manner that permits these numbers to be increased or decreased by the value of another number or to be set to an arbitrary value.<br />(2) A register or storage location used to accumulate the number of occurrences of an event.<br />(3) A representation of information that is cumulative up until the sample is taken. The counter counts values that increase, such as the number of deadlocks. Counters are reset when an instance or a database is stopped and restarted. See also gauge.<br />(4) A binary string that is used by some block cipher modes in an exclusive-OR (XOR) operation. It is incremented and then applied in the encryption or decryption of each block of data. For a given key, a counter should never be repeated.<br />(5) A specialized metric used to keep track of the number of occurrences of a specific situation or event. For example, you can use a counter to track the number of times that a task is started within a process, where that task is contained in a loop.
Industry:Software
(1) A processing step that prepares a program to be run. Activation can include allocating and initializing static storage for programs in a job and completing some portions of binding.<br />(2) In Java, the process of transferring an enterprise bean from secondary storage to memory. (Sun) See also passivation.<br />(3) The attachment of an activity to perform one of a series of processing steps. In order to perform all its processing, an activity may need to be activated several times. In between, it "sleeps". See also pseudoconversational.
Industry:Software
(1) A data manager intended for the storage of system data. The ODM is used for many system management functions. Information used in many commands and SMIT functions is stored and maintained in the ODM as objects with associated characteristics.<br />(2) An AIX proprietary storage mechanism for ASCII stanza files that are edited as part of configuring a drive into the kernel.
Industry:Software
(1) A program module that transfers remote procedure calls (RPCs) and responses between a client and a server. Stubs perform marshalling, unmarshalling, and data format conversion. Both clients and servers have stubs. The Network Interface Definition Language (NIDL) compiler generates client and server stub code from an interface definition.<br />(2) A small module, link-edited into application code, that locates and transfers control to a larger body of related code.<br />(3) The two types of Remote Procedure Calls (RPCs) that are produced by the compiler when an interface is defined. The application code calls the stub, and the RPC mechanism translates this into a call to the appropriate function on the remote machine.<br />(4) A line in a state table that is only partially displayed.<br />(5) A small program routine that substitutes for a longer, possibly remote, program. For example, a stub might be a program module that transfers procedure calls (RPCs) and responses between a client and a server. In Web services, a stub is an implementation of a Java interface generated from a Web Services Definition Language (WSDL) document.<br />(6) A replica or Notes database copy that has not yet been filled with documents. The database is no longer a stub after the first replication takes place.<br />(7) A component containing functionality for testing purposes. A stub is either a pure "dummy", just returning some predefined values, or it is "simulating" a more complex behavior.<br />(8) A protocol extension procedure that connects with the library but remains outside the library.
Industry:Software
(1) A data mapping technique for disk arrays in which fixed-length sequences of virtual-disk data addresses are mapped to sequences of member disk addresses in a regular rotating pattern. See also striped data set.<br />(2) A storage process in which information is split into blocks (a fixed amount of data) and the blocks are written to or read from a series of disks in parallel.
Industry:Software
(1) A program service provided through a programming interface. See also action service.<br />(2) A set of documented interfaces between the z/OS operating system and higher level applications that want to access functions specified in the Single UNIX Specification and earlier standards.<br />(3) Services that are provided by IMS for use by IMS exit routines. These services provide clearly defined interfaces that allow exit routines to request various functions, such as acquiring storage or finding an IMS control block.
Industry:Software
(1) A data set on direct access storage that contains the log records written by an online IMS system. See also system log data set.<br />(2) A data set on direct access storage that contains the log records written by DBCTL. When the current OLDS is full, DBCTL continues logging to a further available OLDS. See also system log data set.
