dependency
•
Tape DEFINEs pass information to the tape process during labeled-tape
operations. Tape DEFINE attributes specify parameters such as the tape device
name and the record format.
dependency. A relationship between two jobs that prevents one of the jobs (the dependent
job) from executing before the other job (the master job) releases it.
dependent job. A job with the WAITON attribute. Dependent jobs do not execute until
released by all the jobs specified by the attribute.
EBCDIC. Extended Binary Coded Decimal Interchange Code. One of the codes used to
represent characters in computers.
executor. A logical entity in a NetBatch scheduler. Executors link jobs, via their classes, to
CPUs. This link enables the scheduler to execute, in the specified CPU, the initial
process (the executor program) of each job. The number of active executors in a
scheduler determines the number of jobs that can run concurrently. For example, a
scheduler with 10 active executors can run up to 10 jobs at the same time. Similarly,
for a scheduler to run the maximum possible number of concurrent jobs (64), it would
need 64 active executors.
executor program. An object file started as a process by a NetBatch scheduler. The object
file can be a command interpreter (for example, TACL) or a compiler (for example,
COBOL). It can also be a query language and report formatter (for example,
ENFORM), a utility (for example, FUP), or a user program.
IMMU. Informational Message Management Utilities. A product used for handling text such
as message text, help text, and keyword substitution. It consists of a utility that loads
and unloads key-sequenced message tables and the procedures needed to access
those tables. NetBatch-Plus uses the IMMU product for handling help text.
input file. A file containing information an executor program needs to execute a job. For
example, if a TACL process is the executor program, the file contains TACL
commands. If the COBOL compiler is the executor program, the file contains the
program source. The syntax of the information in the file must comply with the syntax
rules of the executor program. In a traditional batch processing environment, the job
input file is known as a job control file.
JCF. Job control file. See input file.
job. A logical entity in a NetBatch scheduler. A job’s attributes specify information the
scheduler uses to start an executor program as a NonStop system process. This
information includes:
•
The name of the executor program, its execution priority, input and output files, and
startup parameters
•
Details of the job’s class and selection priority within that class
•
Details of the job’s dependencies
