- WADS
- See write ahead data set (WADS).
- WAN
- See wide area network (WAN).
- warm keypoint
- A keypoint written to the restart data set during controlled shutdown
(after all system activity has ceased). During a subsequent warm restart,
information in the warm keypoint is used to reestablish system tables to the
status they had at controlled shutdown. See also keypoint.
- warm start
- Initialization of a CICS system using selected system
status information obtained during the previous termination.
- WCC
- See write control character (WCC).
- WebSphere Application Server
- Web application server software that runs on a Web server and
that can be used to deploy, integrate, execute, and manage e-business applications.
- wide area network (WAN)
- A network that provides communication
services between devices in a geographic area larger than that served by a
local area network or a metropolitan area network. A WAN may use or provide
public communication facilities. See also local area network.
- worker JVM
- A JVM that shares the class cache owned by the master
JVM, and can be used to run Java programs. A worker JVM has the option CLASSCACHE=YES
specified in its JVM profile.
- working set
- (1) The parts of a
program's executable code, data areas, or both that are being used intensively
and are therefore important to keep in the fastest possible type of storage.
Thus a program's instruction cache working set is the set of program cache
lines that need to be kept in the instruction cache if the program is to run
at maximum speed.
- (2) The amount of real storage required in order
to avoid excessive paging.
- workload
- (1) Work to be tracked, managed and reported
as a unit.
- (2) A group of service classes.
- workload management
- In CICS, a method of optimizing the use of system resources by
spreading workload as evenly as possible between different regions. For more
details about managing workload in a CICSplex, see the CICS Transaction Server Dynamic Transaction Routing in a CICSplex manual.
- workload management mode
- The mode in which workload management
manages system resources in an MVS image within a sysplex. The mode can be
either compatibility mode or goal mode.
- workstation
- A functional
unit at which a user works. A workstation often has some processing capability.
- write ahead data set (WADS)
- In DBCTL, a data set that contains
log records that reflect committed operations but are not yet written to an
online log data set (OLDS).
- write control
character (WCC)
- (1) A control character that follows a write command
in the 3270 data stream and provides control information for executing display
and printer functions.
- (2) A character used with a write-type command
to specify that a particular operation, or combination of operations, is to
be performed at a display station or printer.
