NAME
       prm - Used to delete jobs that are under control of the LCRM

SYNOPSIS
       prm [-h]
       prm [[-b bank [-u uname]] | -n jidlist]
           [-T | -A datetime | -gt time | -m host] [-f] [-h] [-v]

DESCRIPTION
       prm  is  used to delete jobs. A job can only be deleted by its owner or
       by a coordinator of the  bank  from  which  the  job  is  to  draw  its
       resources,  or  by  a LCRM manager. If the caller tries to delete a job
       without proper authority by use of the -b or  -u  options,  it  is  not
       deleted  and  no  error  message  is issued.  On the other hand, if the
       caller tries to delete a job without proper authority by use of the  -n
       option, it is not deleted but an error message is issued. If a selected
       job is running on a host when it is deleted, the job is killed first.

       If the -f option is not specified, each selected job  is  deleted  only
       upon confirmation for that job. The confirmation messages list the LCRM
       jobid, the job owner name, the  account  name  and  the  bank  name  of
       selected job. A reply of y[es] or n[o] is required. If a message is not
       input within ten seconds, a "timeout" message is sent to  the  terminal
       and prm terminates.

       Jobs that have been deleted, using the 'prm' utility, will be placed in
       the history database. Use the -T option to remove the job from the his-
       tory   database.   The   history   database   contains   completed  and
       deleted/removed jobs.

       If no jobs are selected or deleted the following  message  is  sent  to
       standard error:  "No jobs were deleted."


OPTIONS
       -A datetime The date and time that the job is to be removed. If the job
                   is registered to receive a signal, LCRM will send one  when
                   the  prm  is  executed.  If  the user's code calls the LCRM
                   library routine, lrmgetresource, the  stoptime  value  will
                   reflect  the  time that the job will be removed. (for exam-
                   ples of format usage, please see the description of the  -A
                   option in the PSUB man page.)

       -T          Delete  jobs  within  the  history  database.  The  history
                   database contains only completed and/or removed jobs.  This
                   can be used to clear out old jobs the user does not want to
                   see any more.

       -b bank     Delete only jobs that are drawing from  bank.  This  option
                   may not be used in conjunction with the -n option.

       -f          Causes  jobs to be deleted without asking for confirmation.
                   May not be used by a coordinator.

       -gt gracetime
                   The amount of wall clock time that the job is  to  continue
                   to  run  before  it  will be removed by LCRM. If the job is
                   registered to receive a signal, LCRM will send one when the
                   prm  is executed. If the user's code calls the LCRM library
                   routine, lrmgetresource, the stoptime  value  will  reflect
                   the time that the job will be removed.

       -h          Causes a usage message to be printed to standard error.

       -m hostname Remove the named host from list of machines that the job is
                   to be considered for execution. (only valid for a  non-run-
                   ning job)

       -n jobidlist
                   Delete  only  the  jobs with LCRM jobids that correspond to
                   one of the items in jobidlist. jobidlist must  be  a  comma
                   separated list of LCRM jobids.  This option may not be used
                   in conjunction with either the -b or -u options.

       -u uname    Delete only jobs that are owned by uname. This  option  may
                   not be used in conjunction with the -n option.

       -v          Verbose  mode.  Show  the  jobs that were deleted and write
                   error messages to standard error.

EXAMPLES
       If issued by a user who is neither a coordinator nor  a  LCRM  manager,
       the  following  command  deletes every job owned by the calling user if
       the deletion is individually confirmed and lists the jobs deleted.

              >  prm -v

       If issued by a user who is neither a coordinator nor  a  LCRM  manager,
       the following command holds all jobs owned by the calling user that are
       drawing resources from bank A. Confirmation is required.

              >  prm -b A

       The following command deletes the job 3918  when  10  minutes  of  wall
       clock time has passed.

              >  prm -n 3918 -gt 10m

       The  following  command  deletes  the job 3918 if confirmed. No list is
       made of the deletion.

              >  prm -n 3918

       Once job 3918  has  been  deleted,  the  status  goes  to  the  history
       database.   The  following command deletes job 3918, if confirmed, from
       the history database. No list is made of the deletion.

              >  prm -Tn 3918

       If issued by an authorized coordinator, the following  command  deletes
       all  jobs owned by user1 drawing resources from bank B. Confirmation is
       required.

              >  prm -u user1 -b B

       If issued by a LCRM manager the following command deletes all jobs  and
       lists the jobs deleted. Confirmation is not requested.

              >  prm -v -f

NOTE
       If  the  calling user is not the owner of the job being removed, but is
       authorized to do a remove, PRM will prompt the user to see if they wish
       to  enter a message that will be included in the mail message that will
       be sent by LCRM notifying the owner of the removal.

       The message should be entered with <return> separated lines.  Either  a
       '.' in the first position of a line followed by a <return>, or a <ctrl-
       d> will terminate the input. If multiple jobs are being  removed,  then
       any  message  entered will be applied to all jobs that are not owned by
       the calling user.

       Jobs that are in a transient state, (ie. STAGING, MOVING, BAT_WAIT) can
       not  be  removed  and an error will be given  when attempted.  However,
       retrying after the job is running should be successful.
