NAME

       qmgr - pbs batch system manager

SYNOPSIS

       qmgr [-a] [-c command] [-e] [-n] [-z] [server...]

DESCRIPTION

       The qmgr command provides an administrator interface to the batch system.

       The command reads directives from standard input.  The syntax of each directive is checked
       and the appropriate request is sent to the batch server or servers.

       The list or print subcommands of qmgr can be  executed  by  general  users.   Creating  or
       deleting  a  queue  requries  PBS Manager privilege.  Setting or unsetting server or queue
       attributes requires PBS Operator or Manager privilege.

OPTIONS

       -a          Abort qmgr on any syntax errors or any requests rejected by a server.

       -c command  Execute a single command and exit qmgr .

       -e          Echo all commands to standard output.

       -n          No commands are executed, syntax checking only is performed.

       -z          No errors are written to standard error.

OPERANDS

       The server operands identify the name of the  batch  server  to  which  the  administrator
       requests are sent.  Each server conforms to the following syntax:
           host_name[:port]
       where host_name is the network name of the host on which the server is running and port is
       the port number to which to connect.  If port is not specified, the default port number is
       used.

       If server is not specified, the administrator requests are sent to the local server.

STANDARD INPUT

       The  qmgr command reads standard input for directives until end of file is reached, or the
       exit or quit directive is read.

STANDARD OUTPUT

       If Standard Output is connected to a  terminal,  a  command  prompt  will  be  written  to
       standard output when qmgr is ready to read a directive.

       If  the  -e option is specified, qmgr will echo the directives read from standard input to
       standard output.

STANDARD ERROR

       If the -z option is not specified, the qmgr command will write  a  diagnostic  message  to
       standard error for each error occurrence.

EXTENDED DESCRIPTION

       If  qmgr  is invoked without the -c option and standard output is connected to a terminal,
       qmgr will write a prompt to standard output and read a directive from standard input.

       Commands can be abbreviated to their minimum unambiguous form.  A command is terminated by
       a  new line character or a semicolon, ";", character.  Multiple commands may be entered on
       a single line.  A command may extend across lines by escaping the new line character  with
       a back-slash "\".

       Comments  begin  with the # character and continue to end of the line.  Comments and blank
       lines are ignored by qmgr.

DIRECTIVE SYNTAX

A qmgr directive is one of the following forms:

command server [names] [attr OP value[,attr OP value,...]]
command queue [names] [attr OP value[,attr OP value,...]]
command node [names] [attr OP value[,attr OP value,...]]

Where,

command is the command to perform on a object. Commands are:

active sets the active objects. If the active objects are specified, and the
name is not given in a qmgr cmd the active object names will be used.

create is to create a new object, applies to queues and nodes.

delete is to destroy an existing object, applies to queues and nodes.

set is to define or alter attribute values of the object.

unset is to clear the value of attributes of the object. Note, this form
does not accept an OP and value, only the attribute name.

list is to list the current attributes and associated values of the object.

print is to print all the queue and server attributes in a format that will
be usable as input to the qmgr command.

names is a list of one or more names of specific objects The name list is in the form:
[name][@server][,queue_name[@server]...]
with no intervening white space. The name of an object is declared when the
object is first created. If the name is @server, then all the objects of
specified type at the server will be effected.

attr specifies the name of an attribute of the object which is to be set or modified.
If the attribute is one which consist of a set of resources, then the attribute
is specified in the form:
attribute_name.resource_name

OP operation to be performed with the attribute and its value:

= set the value of the attribute. If the attribute has a existing value,
the current value is replaced with the new value.

+= increase the current value of the attribute by the amount in the new
value.

-= decrease the current value of the attribute by the amount in the new
value.

value the value to assign to an attribute. If the value includes white space, commas
or other special characters, such as the # character, the value string must be
inclosed in quote marks (").

The following are examples of qmgr directives:

create queue fast priority=10,queue_type=e,enabled = true,max_running=0
set queue fast max_running +=2
create queue little
set queue little resources_max.mem=8mw,resources_max.cput=10
unset queue fast max_running
set node state = down,offline
active server s1,s2,s3
list queue @server1
set queue max_running = 10 - uses active queues

EXIT STATUS

       Upon successful processing of all the operands presented to the  qmgr  command,  the  exit
       status will be a value of zero.

       If  the  qmgr command fails to process any operand, the command exits with a value greater
       than zero.
