- Information that adds meaning to something else. For example, a task's context could be the host connection or session with which it is associated. If the task's context is maintained, or preserved, the session remains connected after the task has completed, and the session is available to run the next task.
See also stateful task.
- A file containing COBOL data declarations that was included when the COBOL program on the host was compiled. A particular copybook may be included in more than one COBOL program; a program can include several copybooks.

See also bean.
- Java caching
- The process of installing Java applets or other software on a client so that the files can be run locally rather than from the server. Java caching is controlled by settings on the server rather than by the browsers cache settings. Clearing the browsers cache (either the memory cache or the disk cache) does not remove files installed via Java caching. The location of the files and the procedure for removing them varies, depending on the browser and the applet. Netscape 6.x does not support Java caching.

- In Smart Connectors for Screens, the process of going from the current step to the desired step. The purpose of navigation is to automate keystrokes so that the Runtime Service will reproduce them when the task is run. This includes both entering data and moving between steps.
- A file that contains the navigation information required to access screens within a host application. This information can include screens, fields, keystrokes, and paths between screens.
- Native Access
- A generic representation of the host screen data provided through the Smart Connectors for Screens, which exposes all the data needed to describe the host screens.
- 1. In tree structures, a location (set of information) on the tree that can have links to one or more nodes below it (child nodes). The topmost node is called the root. The root can have zero or more child nodes; the root is the parent node to its children. Each child node can in turn have zero or more children of its own. Every node in a tree has exactly one parent node (except for the root, which has none), and all nodes in the tree are descendants of the root node. 2. In an XML document that is modeled after a tree, each element in the tree is considered a node. An XML-based application can store data in all the different types of nodes and in all the fields of each node. XML states that there must be at least one element in each document: the root node. All nodes are one of four types: character, processing instruction (PI), comment, element. Character, PI, and comment nodes have no children, so they are always leaf nodes in an XML document tree.
- offline screen mode
- In Smart Connectors for Screens, a mode in which you use previously recorded screens to create tasks, without a live connection to the host.
- 1. A group of related Java classes and interfaces that provides access protection and namespace management. Bundling groups of related Java classes and interfaces into a package builds in control access between classes (both inside and outside the package), and makes it possible to quickly determine the relationship between the classes and the interfaces. Also, by creating a new namespace, it prevents the names of classes from conflicting with those in other packages. 2. In MCS, an application or service that can be remotely installed on an MCS-managed server.
- 1. The first of two or more connected objects in a hierarchical data structure system, a parent structure invokes its child structure, which inherits the parents attributes. 2. A process from which a child process is started.
- 1. The relationship between processes in a multitasking environment in which the parent process calls the child process and most often suspends its own operation until the child process aborts or is completed.
2. The relationship between nodes in a tree data structure in which the parent is one step closer to the root (that is, one level higher) than the child.
See also child.
- A setting for an application or tool, typically set by users.

- primary server
- Within each server cluster, there is one primary server and one or more secondary servers. All configuration changes take place through the cluster's primary server. Configuration data, event log files, and trace log files are dynamically replicated across all servers in the cluster, ensuring that all active servers have access to the latest data. Although you can access the MCS console from another server in the cluster just as you do from the primary server, the console request is automatically redirected to the primary server. If the primary server ever goes off-line, the server with next highest priority in the cluster takes over primary server responsibilities.

- In Smart Connectors for Screens or Presentation Designer, a rectangular area of the host screen that contains one or more records. The records contained in a table may exist on multiple pages spanning multiple screens.
See also detail table.
- A sequence of transactions that perform a particular job. A task can be a simple data transfer, such as updating a database record, or it can be more complex, such as logging onto a host application, navigating to a particular screen, and sending and retrieving data. It could even be a combination of tasks that make up a business application. A task consists of one or more transactions.
Tasks are created in Attachmate Designer Studio using Task Builders (for example, Task Builder for IMS) that are specific to the data source. Users create tasks by defining the inputs and outputs to the task, and the relationships between them. In more complex cases, users might define mappings between disparate data sources.
See also transaction.
- task bean
- A Java bean, generated by a Task Builder, that uses the Attachmate ITask interface. A separate bean is generated for each task.
See also bean.
- Task Builder
- A component used to create tasks from host application information for use in custom applications. For example, Task Builder for Screens is used to capture host screens and define task inputs and outputs. Tasks are generated as task interface objects, which are later combined to create custom applications.
- task file
- An XML document that maps tasks to systems. The content varies, depending on the connector used. A task file contains connectivity and systems information, such as the location of an application on the host, or statements to execute, and must contain the definition for the task specified by the task ID. It may also point to additional files it needs, such as bridges and transformation files, and may include its metadata, which describes the inputs and outputs required to perform specified tasks (for some connectors, the metadata is stored in a separate file).
- task ID
- A unique identifier for a task. In Attachmate connector products, a task ID cannot begin with a digit. In addition, if beans will be generated from tasks, Java naming conventions must be followed. Identifiers in Java cannot include characters other than letters, numbers, the underscore (_), and the dollar sign ($).
- task interface object
- The code generated by a Task Builder through which an application interacts with a task. For example, in Task Builder for Screens, the user can create one or more tasks and generate task interface objects as a task file, Java beans, or Web services. Later, an application that is created to run tasks makes use of the task interface objects to communicate with the runtime service.
See also bean, service bean, task bean, task file, Web service.
- task resource
- See resource.
- task step
- The screen and associated inputs and outputs that define the action to be performed at runtime at a particular point in a task, including instructions on how to proceed to the next step.
- Terminal Viewer
- See viewer.
- In Presentation Designer, a resource that, combined with rules, controls the look, feel, and actions of your application in relation to its host connection. Multiple rules can exist within a single theme, but only one theme can be applied to any application.
See also rule.
- 1. The smallest unit that a task can be broken into. A task can include one or more transactions. 2. A unit of work that modifies data. For a transaction to be completed and changes to be made permanent, the transaction must be completed in its entirety. When it completes successfully, changes are committed; when it is interrupted and does not complete, changes are rolled back.
- A process that reformats a single source of Web content to suit the needs of different display devices, such as both hand-held and desktop displays. Transcoding eliminates the need to rewrite content to meet the requirements of each device separately.
- transient step
- One or more transitional screens sent by the host without the user sending an AID key to the host.
- translation table
- A file that modifies the data sent between the host and a client to ensure that the client can display characters that are not part of the U.S. English character set.
- A data structure containing zero or more nodes that are linked together in a hierarchical fashion. The topmost node is called the root. The root can have zero or more child nodes, connected by edges (links); the root is the parent node to its children. Each child node can in turn have zero or more children of its own. Nodes sharing the same parent are called siblings. Every node in a tree has exactly one parent node (except for the root, which has none), and all nodes in the tree are descendants of the root node. These relationships ensure that there is always one and only one path from the root node to any other node in the tree.
- unattended installation
- An installation performed without user interaction, in which installation dialog boxes are suppressed. Also known as a silent installation.
- unexpected screen
- A screen that does not match a destination screen for the current step in a task. An unexpected screen may be recorded in the NavMap but occurs out of the order expected.
- unrecognized screen
- The default global screen handler, or navigation aid, to use when an unexpected screen is encountered that does not match any of the recorded global screens. When this occurs, the Task Builder attempts to invoke the unrecognized screen's transition action before the task fails.
See also global screen, unexpected screen.
