�initial reference: A well-known reference associated with an identifier.
�initial stack segment: The first stack segment. A stack consists of the initial stack segment and zero or more additional segments or increments.
�initial state: In COBOL, the state of a program when it is first called in a run unit.
�initial thread: The thread that is started automatically by the system when a job or process is started. See also secondary thread.
�initiating task: The job management task that controls the selection of a job and the preparation of the steps of that job for execution.
�initiation queue: A local queue on which the queue manager puts trigger messages.
�initiation request: The name of the first process in a collaborative workflow cycle.
�initiative: A task developed to achieve objectives or close the gap between performance and targets. Initiatives are associated with individual objectives and often known as projects, actions, or activities. See also objective.
�initiator: (1) The role of a node using the two-phase commit protocol when its local transaction program issues a commit operation that begins the two-phase commit flows. The initiator is the root node of a transaction program network. See also responder.; (2) In OSI Communications Subsystem, the application entity that starts an application association.; (3) The part of an operating system that reads and processes control statements from the system input device.; (4) The system component that originates an I/O command over an I/O bus or network. I/O adapters and network interface cards are typical initiators. See also target.; (5) In Small Computer System Interface (SCSI) technology, the part of a host computer that communicates with its attached targets. See also SCSI device.
�inline: (1) Pertaining to spooled input data that is read into a job by a reader.; (2) In Content Manager, the property of an object that is online and in a drive, but has no active mounts.; (3) To replace a function call with a copy of the function's code during compilation.
�inline backup: The process of copying a specific data set to a migration-level-1 volume from a batch environment. Inline backup allows users to back up data sets in the middle of a job.
�inline copy: A copy that is produced by the LOAD or REORG utility. The data set that the inline copy produces is logically equivalent to a full image copy that is produced by running the COPY utility with read-only access.
�inline data file: A file created by a Data (//DATA) command that is included as part of a job when the job is read from an input device or a database file. The file is deleted when the job ends.
�inline direction (I, I-direction): The direction in which successive characters are added to a line of text.
�inline function: A function whose actual code replaces a function call. A function that is both declared and defined in a class definition is an example of an inline function.

�inlining: The process of replacing a function call with a copy of the function's code during compilation.
�inner join: The result of a join operation that includes only the matched rows of both tables that are being joined. See also outer join, join.
�i-node: The internal structure that describes the individual files in the UNIX file system. An i-node contains the node, type, owner, and location of a file.
�i-node number: A number specifying a particular i-node file in the file system.
�inoperative package: A package that cannot be used because one or more user-defined functions or procedures on which the package depends were dropped. See also invalid package.
�inoperative trigger: A trigger that depends on an object that has been dropped or made inoperative or on a privilege that has been revoked.
�inoperative view: A view that is not usable because a privilege on an underlying table
