The attributes of a batch job are altered by a request to the
batch server that manages the batch job. The qalter utility is a
user-accessible batch client that requests the alteration of the
attributes of one or more batch jobs.
The qalter utility shall alter the attributes of those batch
jobs, and only those batch jobs, for which a batch job_identifier
is presented to the utility.
The qalter utility shall alter the attributes of batch jobs in
the order in which the batch job_identifiers are presented to the
utility.
If the qalter utility fails to process a batch job_identifier
successfully, the utility shall proceed to process the remaining
batch job_identifiers, if any.
For each batch job_identifier for which the qalter utility
succeeds, each attribute of the identified batch job shall be
altered as indicated by all the options presented to the utility.
For each identified batch job for which the qalter utility fails,
the utility shall not alter any attribute of the batch job.
For each batch job that the qalter utility processes, the utility
shall not modify any attribute other than those required by the
options and option-arguments presented to the utility.
The qalter utility shall alter batch jobs by sending a Modify Job
Request to the batch server that manages each batch job. At the
time the qalter utility exits, it shall have modified the batch
job corresponding to each successfully processed batch
job_identifier. An attempt to alter the attributes of a batch
job in the RUNNING state is implementation-defined.
