Glossary
abend. An acronym for abnormal end (of a process).
ASSIGN. A parameter that assigns the name of an actual file to a logical file name in a
program. It also can specify the file’s creation and open attributes. For more
information, see the TACL Reference Manual and the TACL Programming Guide.
attachment set. A named set of ASSIGNs, DEFINEs, and PARAMs.
attribute. A characteristic of an entity (for example, the selection priority of a job). In an SPI
interface, an attribute of an object is usually expressed as a simple token or a field in
an extensible structured token. The attributes of a token are its length, count, address,
and offset. Programs can get these through special SSGET operations.
BATCHCAL. The file ID of the NetBatch calendar program. The program enables you to
generate a run calendar, display run times, and reformat an old calendar file to
the current format.
BATCHCOM. The file ID of the NetBatch command interpreter program. BATCHCOM
enables interactive and noninteractive manipulation of the scheduler; the
scheduler’s executors, classes, and attachment sets; and jobs.
BPROC. The former file ID of NBEXEC, the NetBatch executor program. See NBEXEC.
buffer. A sequence of memory locations used for temporary storage of data. For instance,
data to be sent in an interprocess message is encoded in a buffer from which it is
copied by the file system. The data is delivered to a buffer addressable by the
recipient. See also message; SPI buffer.
built-in. A primitive function or variable in the TACL program. Names of built-ins always
begin with a pound sign (#).
calendar. See run calendar
.
class. A logical entity in the scheduler. A class’s purpose is to group jobs and to control their
flow to executors and thereby to the executors’ processors. Classes are the job-
queuing mechanisms of the scheduler. You can assign a class to multiple executors to
give its jobs opportunities to execute in different processors.
collector. An EMS process that accepts event messages from subsystems and logs them in
the event log. See also distributor
.
command. A demand for action by or information from a subsystem, or the operation
demanded by an operator or application. A command is typically conveyed as an
interprocess message from an application to a subsystem.
command message. An SPI message, containing a command, that is sent from an
application program to a subsystem. See SPI message.
