Letra Q
QSAM
See queued sequential access method (QSAM).
qualified call
A DL/I call that contains at least one segment search argument.
quasi-reentrant
The attribute used to describe CICS application programs that run under the CICS quasi-reentrant task control block (QR TCB). CICS obtains a separate copy of program working storage for each task that executes application program code. Only one task can execute application program code at a time. CICS can ensure the necessary serialization of user application programs that access any kind of shared resources, whether CICS- or user-managed, to stop different tasks from interfering with each other. The user application program need not be reenterable strictly according to the DFSMS program management definition. See also reentrant, reentrable.
queue
(1) A list of messages, jobs, files, or requests waiting to be read, processed, printed, or distributed in a predetermined order.
(2) A line or list of items waiting to be processed; for example, work to be performed or messages to be displayed or transmitted.
queued sequential access method (QSAM)
An extended version of the basic sequential access method (BSAM) that forms a queue of input data blocks that are awaiting processing or of output data blocks that are awaiting transfer to auxiliary storage or to an output device.
Queue Manager
A component of CICSPlex SM that creates and manages queues of data in a cache that is shared by a CMAS and its local MASs.
