See auxiliary HADR standby database.
All addressable storage other than main storage. See also memory.
- One or more storage units that are defined from the storage devices or storage device subsystems that make up auxiliary storage. An ASP provides a way of organizing data to limit the effect of storage-device failures and to reduce recovery time. See also main storage pool.
- A group of disk units defined from the auxiliary storage devices. See also system ASP, user ASP.
auxiliary storage - TS queue
In CICS, a temporary storage queue that is in a physical file managed by CICS. Auxiliary storage should be used to store large amounts of data, or data needed for a long period of time. See also main storage - TS queue.
A table that stores columns outside the table in which they are defined. See also base table.
auxiliary trace data set
A sequentially organized data set on disk or tape, used to record all trace entries generated while the auxiliary trace function is active. Either one or two auxiliary trace data sets can be defined; the latter allows the data sets to be switched when the one currently being used is full.
- The total amount of time that a resource can devote to new assignments.
- The time periods during which a resource is accessible. For example, a contractor might have an availability of 9 AM to 5 PM every weekday, and 9 AM to 3 PM on Saturdays.
- The successful execution of a monitored transaction over a specified period of time. See also transaction.
- The degree to which a system or resource is ready when needed to process data.
- The delivery of reliable service during scheduled periods.
- The condition allowing users to access and use their applications and data.
- A service management process that helps to define customer requirements for information technology service availability, the capabilities of the IT infrastructure to deliver those levels of availability, and the actions that are needed to improved availability. See also deployment management, operations and administration, security management.
- In DFSMShsm, the process of ensuring that a current version (backup copy) of the installation's data sets resides on tape or a direct access storage device (DASD).
available to promise inventory (ATP inventory)
The inventory that is available in stock (on hand) plus the inventory that is on order, not including inventory that is currently being processed, reserved or allocated to backorders.
available to promise monitoring rule (ATP monitoring rule)
A business rule that is used to set up a monitoring system for tracking inventory item availability and raising specific actions when the inventory falls below a specified minimum level. The availability of an item can be tracked on the current day, subsequent days within the ATP timeframe, and subsequent days outside the ATP timeframe.
available to promise rule (ATP rule)
A business rule that determines the availability of an item for current and future demand. This determination makes the most efficient use of inventory so that items are not set aside for future orders when they could be used to fulfill more immediate demands.
average throughput rate
The power of a system to process a representative work load. The power of the system is measured in units of data processing work; for example, jobs or transactions successfully completed per hour, minute, or second.

- A part of a location step in a search path. An axis defines the direction of the search for objects in the object hierarchy of the content store. An axis indicates where to search for objects by defining a set of objects relative to the current context object. For example, the ancestor axis specifies the ancestor of the current context object.
- In Business Graphics Utility and the GDDM function, one of the intersecting horizontal or vertical scales where data values are plotted on a chart.
- The direction of movement through an instance of the XQuery and XPath data model. The six supported axes are child, parent, self, attribute, descendant, and descendant-or-self.
- The representation in screen coordinates of the points where a coordinate value varies and all other coordinate values are zero.
The "authorized cross-memory" server environment. A series of modules providing runtime services for CICS-related cross-memory servers which run in MVS authorized state (unlike CICS itself, which runs unauthorized once initialization has completed) such as the temporary storage data sharing server.
A keyboard in which the keys in the second-from-top row (row D) are labeled (from left to right): A, Z, E, R, T, Y, U, I, O, and P. See also QWERTY keyboard.
