qconf - Sun Grid Engine Queue Configuration

SYNTAX

qconf options

DESCRIPTION

Qconf allows the system administrator to add, delete, and modify the current Sun Grid
Engine configuration, including queue management, host management, complex management and
user management. Qconf also allows you to examine the current queue configuration for
existing queues.

Qconf allows the use of the backslash, '\', character at the end of a line to indicate
that the next line is a continuation of the current line. When displaying settings, such
as the output of one of the -s* options, qconf will break up long lines (lines greater
than 80 characters) into smaller lines using backslash line continuation where possible.
Lines will only be broken up at commas or whitespace. This feature can be disabled by
setting the SGE_SINGLE_LINE environment variable.

OPTIONS

Unless denoted otherwise, the following options and the corresponding operations are
available to all users with a valid account.

-Aattr obj_spec fname obj_instance,...
<add to object attributes>
Similar to -aattr (see below) but takes specifications for the object attributes to
be enhanced from file named fname. As opposed to -aattr, multiple attributes can be
enhanced. Their specification has to be enlisted in fname following the file format
of the corresponding object (see queue_conf(5) for the queue, for example).
Requires root/manager privileges.

-Acal fname <add calendar>
Adds a new calendar definition to the Sun Grid Engine environment. Calendars are
used in Sun Grid Engine for defining availability and unavailability schedules of
queues. The format of a calendar definition is described in calendar_conf(5).

The calendar definition is taken from the file fname. Requires root/ manager
privileges.

-Ackpt fname <add ckpt. environment>
Add the checkpointing environment as defined in fname (see checkpoint(5)) to the
list of supported checkpointing environments. Requires root or manager privileges.

-Aconf file_list <add configurations>
Add the configurations (see sge_conf(5)) specified in the files enlisted in the
comma separated file_list. The configuration is added for the host that is
identical to the file name.
Requires root or manager privileges.

-Ae fname <add execution host>
Add the execution host defined in fname to the Sun Grid Engine cluster. The format
of the execution host specification is described in host_conf(5). Requires root or
manager privileges.

-Ahgrp file <add host group config>
Add the host group configuration defined in file. The file format of file must
comply to the format specified in hostgroup(5). Requires root or manager
privileges.

-Arqs fname <add RQS configuration>
Add the resource quota set (RQS) defined in the file named fname to the Sun Grid
Engine cluster. Requires root or manager privileges.

-Ap fname <add PE configuration>
Add the parallel environment (PE) defined in fname to the Sun Grid Engine cluster.
Requires root or manager privileges.

used for queue usage authentication. Requires root/manager/operator privileges.

-cb This parameter can be used since Sun Grid Engine version 6.2u5 in combination with
the command line switch -sep. In that case the output of the corresponding command
will contain information about the added job to core binding functionality.

If -cb switch is not used then -sep will behave as in GE version 6.2u4 and below.

Please note that this command-line switch will be removed from Sun Grid Engine with
the next major release.

-Dattr obj_spec fname obj_instance,...
<del. from object attribs>
Similar to -dattr (see below) but the definition of the list attributes from which
entries are to be deleted is contained in the file named fname. As opposed to
-dattr, multiple attributes can be modified. Their specification has to be enlisted
in fname following the file format of the corresponding object (see queue_conf(5)
for the queue, for example).
Requires root/manager privileges.

-Mattr obj_spec fname obj_instance,...
<mod. object attributes>
Similar to -mattr (see below) but takes specifications for the object attributes to
be modified from file named fname. As opposed to -mattr, multiple attributes can be
modified. Their specification has to be enlisted in fname following the file format
of the corresponding object (see queue_conf(5) for the queue, for example).
Requires root/manager privileges.

-Mc fname <modify complex>
Overwrites the complex configuration by the contents of fname. The argument file
must comply to the format specified in complex(5). Requires root or manager
privilege.

configuration entries contained in file will be applied. Configuration entries not
contained in file will be deleted. The file format of file must comply to the
format specified in hostgroup(5).

-Mrqs fname [mrqs_name] <modify RQS configuration>
Same as -mrqs (see below) but instead of invoking an editor to modify the RQS
configuration, the file fname is considered to contain a changed configuration. The
name of the rule set in fname must be the same as rqs_name. If rqs_name is not set,
all rule sets are overwritten by the rule sets in fname Refer to
sge_resource_quota(5) for details on the RQS configuration format. Requires root
or manager privilege.

configuration the file fname is considered to contain a changed configuration.
Refer to sge_pe(5) for details on the PE configuration format. Requires root or
manager privilege.

-Mprj fname <modify project config.>
Same as -mprj (see below) but instead of invoking an editor to modify the project
configuration the file fname is considered to contain a changed configuration.
Refer to project(5) for details on the project configuration format. Requires root
or manager privilege.

-Mq fname <modify queue configuration>
Same as -mq (see below) but instead of invoking an editor to modify the queue
configuration the file fname is considered to contain a changed configuration.

with the same name. See access_list(5) for information on the ACL configuration
format. Requires root or manager privilege.

-Muser fname <modify user>
Modify the user defined in fname in the Sun Grid Engine cluster. The format of the
user specification is described in user(5). Requires root or manager privileges.

-Rattr obj_spec fname obj_instance,...
<replace object attribs>
Similar to -rattr (see below) but the definition of the list attributes whose
content is to be replace is contained in the file named fname. As opposed to
-rattr, multiple attributes can be modified. Their specification has to be enlisted
in fname following the file format of the corresponding object (see queue_conf(5)
for the queue, for example).
Requires root/manager privileges.

-aattr obj_spec attr_name val obj_instance,...
<add to object attributes>
Allows adding specifications to a single configuration list attribute in multiple
instances of an object with a single command. Currently supported objects are the
queue, the host, the host group, the parallel environment, the resource quota sets
and the checkpointing interface configuration being specified as queue , exechost ,
hostgroup , pe , rqs or ckpt in obj_spec. For the obj_spec queue the obj_instance
can be a cluster queue name, a queue domain name or a queue instance name. Find
more information concerning different queue names in sge_types(1). Depending on
the type of the obj_instance this adds to the cluster queues attribute sublist the
cluster queues implicit default configuration value or the queue domain
configuration value or queue instance configuration value. The queue
load_thresholds parameter is an example of a list attribute. With the -aattr
option, entries can be added to such lists, while they can be deleted with -dattr,
modified with -mattr, and replaced with -rattr.
For the obj_spec rqs the obj_instance is a unique identifier for a specific rule.
The identifier consists of a rule-set name and either the number of the rule in the
list, or the name of the rule, separated by a /
The name of the configuration attribute to be enhanced is specified with attr_name
followed by val as a name=value pair. The comma separated list of object instances
(e.g., the list of queues) to which the changes have to be applied are specified at
the end of the command.
The following restriction applies: For the exechost object the load_values
attribute cannot be modified (see host_conf(5)).
Requires root or manager privileges.

-acal calendar_name <add calendar>
Adds a new calendar definition to the Sun Grid Engine environment. Calendars are
used in Sun Grid Engine for defining availability and unavailability schedules of
queues. The format of a calendar definition is described in calendar_conf(5).

With the calendar name given in the option argument qconf will open a temporary
file and start up the text editor indicated by the environment variable EDITOR
(default editor is vi(1) if EDITOR is not set). After entering the calendar
definition and closing the editor the new calendar is checked and registered with
sge_qmaster(8). Requires root/manager privileges.

-ackpt ckpt_name <add ckpt. environment>
Adds a checkpointing environment under the name ckpt_name to the list of
checkpointing environments maintained by Sun Grid Engine and to be usable to submit
checkpointing jobs (see checkpoint(5) for details on the format of a checkpointing
environment definition). Qconf retrieves a default checkpointing environment
configuration and executes vi(1) (or $EDITOR if the EDITOR environment variable is
set) to allow you to customize the checkpointing environment configuration. Upon
exit from the editor, the checkpointing environment is registered with
sge_qmaster(8). Requires root/manager privileges.

-aconf host,... <add configuration>
Successively adds configurations (see sge_conf(5)) For the hosts in the comma
separated file_list. For each host, an editor ($EDITOR indicated or vi(1)) is
invoked and the configuration for the host can be entered. The configuration is
registered with sge_qmaster(8) after saving the file and quitting the editor.
Requires root or manager privileges.

-ae [host_template] <add execution host>
Adds a host to the list of Sun Grid Engine execution hosts. If a queue is
configured on a host this host is automatically added to the Sun Grid Engine
execution host list. Adding execution hosts explicitly offers the advantage to be
able to specify parameters like load scale values with the registration of the
execution host. However, these parameters can be modified (from their defaults) at
any later time via the -me option described below.
If the host_template argument is present, qconf retrieves the configuration of the
specified execution host from sge_qmaster(8) or a generic template otherwise. The
template is then stored in a file and qconf executes vi(1) (or the editor indicated
by $EDITOR if the EDITOR environment variable is set) to change the entries in the
file. The format of the execution host specification is described in host_conf(5).
When the changes are saved in the editor and the editor is quit the new execution
host is registered with sge_qmaster(8). Requires root/manager privileges.

-ah hostname,... <add administrative host>
Adds hosts hostname to the Sun Grid Engine trusted host list (a host must be in
this list to execute administrative Sun Grid Engine commands, the sole exception to
this being the execution of qconf on the sge_qmaster(8) node). The default Sun Grid
Engine installation procedures usually add all designated execution hosts (see the
-ae option above) to the Sun Grid Engine trusted host list automatically. Requires
root or manager privileges.

-ahgrp group <add host group config.>
Adds a new host group with the name specified in group. This command invokes an
editor (either vi(1) or the editor indicated by the EDITOR environment variable).
The new host group entry is registered after changing the entry and exiting the
editor. Requires root or manager privileges.

-arqs [rqs_name] <add new RQS>
Adds one or more Resource Quota Set (RQS) description under the names rqs_name to
the list of RQSs maintained by Sun Grid Engine (see sge_resource_quota(5) for
details on the format of a RQS definition). Qconf retrieves a default RQS
configuration and executes vi(1) (or $EDITOR if the EDITOR environment variable is
set) to allow you to customize the RQS configuration. Upon exit from the editor,
the RQS is registered with sge_qmaster(8). Requires root or manager privileges.

-am user,... <add managers>
Adds the indicated users to the Sun Grid Engine manager list. Requires root or
manager privileges.

-ao user,... <add operators>
Adds the indicated users to the Sun Grid Engine operator list. Requires root or
manager privileges.

-ap pe_name <add new PE>
Adds a Parallel Environment (PE) description under the name pe_name to the list of
PEs maintained by Sun Grid Engine and to be usable to submit parallel jobs (see
sge_pe(5) for details on the format of a PE definition). Qconf retrieves a default
PE configuration and executes vi(1) (or $EDITOR if the EDITOR environment variable
is set) to allow you to customize the PE configuration. Upon exit from the editor,
the PE is registered with sge_qmaster(8). Requires root/manager privileges.

-at thread_name <activates thread in master>
Activates an additional thread in the master process. thread_name might be either
"scheduler" or "jvm". The corresponding thread is only started when it is not
already running. There might be only one scheduler and only one jvm thread in the
master process at the same time.

-aprj <add new project>
Adds a project description to the list of registered projects (see project(5)).
Qconf retrieves a template project configuration and executes vi(1) (or $EDITOR if
the EDITOR environment variable is set) to allow you to customize the new project.
Upon exit from the editor, the template is registered with sge_qmaster(8).
Requires root or manager privileges.

-aq [queue_name] <add new queue>
Qconf retrieves the default queue configuration (see queue_conf(5)) and executes
vi(1) (or $EDITOR if the EDITOR environment variable is set) to allow you to
customize the queue configuration. Upon exit from the editor, the queue is
registered with sge_qmaster(8). A minimal configuration requires only that the
queue name and queue hostlist be set. Requires root or manager privileges.

-as hostname,... <add submit hosts>
Add hosts hostname to the list of hosts allowed to submit Sun Grid Engine jobs and
control their behavior only. Requires root or manager privileges.

-astnode node_path=shares,... <add share tree node>

node_path is a hierarchical path ([/]node_name[[/.]node_name...]) specifying the
location of the new node in the share tree. The base name of the node_path is the
name of the new node. The node is initialized to the number of specified shares.
Requires root or manager privileges.

-astree <add share tree>
Adds the definition of a share tree to the system (see share_tree(5)). A template
share tree is retrieved and an editor (either vi(1) or the editor indicated by
$EDITOR) is invoked for modifying the share tree definition. Upon exiting the
editor, the modified data is registered with sge_qmaster(8). Requires root or
manager privileges.

-Astree fname <add share tree>
Adds the definition of a share tree to the system (see share_tree(5)) from the file
fname. Requires root or manager privileges.

-k{m|s|e[j] {host,...|all}} <shutdown Sun Grid Engine>
Note: The -ks switch is deprecated, may be removed in future release. Please use
the -kt switch instead.
Used to shutdown Sun Grid Engine components (daemons). In the form -km
sge_qmaster(8) is forced to terminate in a controlled fashion. In the same way the
-ks switch causes termination of the scheduler thread. Shutdown of running
sge_execd(8) processes currently registered is initiated by the -ke option. If -kej
is specified instead, all jobs running on the execution hosts are aborted prior to
termination of the corresponding sge_execd(8). The comma separated host list
specifies the execution hosts to be addressed by the -ke and -kej option. If the
keyword all is specified instead of a host list, all running sge_execd(8) processes
are shutdown. Job abortion, initiated by the -kej option will result in dr state
for all running jobs until sge_execd(8) is running again.

attributes are described in queue_conf(1).
This operation only works on a single queue instance or domain. It cannot be used
on a cluster queue. In the case where the obj_spec is "queue@@hostgroup", the
attribute values defined in attr_nm which are set for the indicated hostgroup are
deleted, but not those which are set for the hosts contained by that hostgroup. If
the attr_nm is '*', all attribute values set for the given queue instance or domain
are deleted.
The main difference between -dattr and -purge is that -dattr removes a value from a
single list attribute, whereas -purge removes one or more overriding attribute
settings from a cluster queue configuration. With -purge, the entire attribute is
deleted for the given queue instance or queue domain.

-rattr obj_spec attr_name val obj_instance,...
<replace object attributes>
Allows replacing a single configuration list attribute in multiple instances of an
object with a single command. Find more information concerning obj_spec and

-shgrp_tree group <show host group tree>
Shows a tree like structure of host group.

-shgrp_resolved group <show host group hosts>
Shows a list of all hosts which are part of the definition of host group. If the
host group definition contains sub host groups than also these groups are resolved
and the hostnames are printed.

-srqs [rqs_name_list] <show RQS configuration>
Show the definition of the resource quota sets (RQS) specified by the argument.

-srqsl <show RQS-list>
Show a list of all currently defined resource quota setss (RQSs).

-sm <show managers>
Displays the managers list.

-so <show operators>
Displays the operator list.

-sobjl obj_spec attr_name val <show object list>
Shows a list of all configuration objects for which val matches at least one
configuration value of the attributes whose name matches with attr_name.

Obj_spec can be "queue" or "queue_domain" or "queue_instance" or "exechost". Note:
When "queue_domain" or "queue_instance" is specified as obj_spec matching is only
done with the attribute overridings concerning the host group or the execution
host. In this case queue domain names resp. queue instances are returned.

Attr_name can be any of the configuration file keywords enlisted in queue_conf(5)
or host_conf(5). Also wildcards can be used to match multiple attributes.

Val can be an arbitrary string or a wildcard expression.

-sp pe_name <show PE configuration>
Show the definition of the parallel environment (PE) specified by the argument.

-spl <show PE-list>
Show a list of all currently defined parallel environments (PEs).

-sprj project <show project>
Shows the definition of the specified project (see project(5)).

-sprjl <show project list>
Shows the list of all currently defined projects.

-sq wc_queue_list <show queues>
Displays one or multiple cluster queues or queue instances. A description of
wc_queue_list can be found in sge_types(1).

-sql <show queue list>
Show a list of all currently defined cluster queues.

-ss <show submit hosts>
Displays the Sun Grid Engine submit host list.

-ssconf <show scheduler configuration>
Displays the current scheduler configuration in the format explained in
sched_conf(5).

-sstnode node_path,... <show share tree node>
Shows the name and shares of the specified share tree node(s) (see share_tree(5)).
The node_path is a hierarchical path ([/]node_name[[/.]node_name...]) specifying
the location of a node in the share tree.

-sstree <show share tree>
Shows the definition of the share tree (see share_tree(5)).

-sst <show formatted share tree>
Shows the definition of the share tree in a tree view (see share_tree(5)).

-sss <show scheduler status>
Currently displays the host on which the Sun Grid Engine scheduler is active or an
error message if no scheduler is running.

-su acl_name <show user ACL>
Displays a Sun Grid Engine user access list (ACL).

-sul <show user lists>
Displays a list of names of all currently defined Sun Grid Engine user access lists
(ACLs).

-suser user,... <show user>
Shows the definition of the specified user(s) (see user(5)).

-suserl <show users>
Shows the list of all currently defined users.

-tsm <trigger scheduler monitoring>
The Sun Grid Engine scheduler is forced by this option to print trace messages of
its next scheduling run to the file <sge_root>/<cell>/common/schedd_runlog. The
messages indicate the reasons for jobs and queues not being selected in that run.
Requires root or manager privileges.

Note, that the reasons for job requirements being invalid with respect to resource
availability of queues are displayed using the format as described for the qstat(1)
-F option (see description of Full Format in section OUTPUT FORMATS of the qstat(1)
manual page.

ENVIRONMENTAL VARIABLES

SGE_ROOT Specifies the location of the Sun Grid Engine standard configuration files.

SGE_CELL If set, specifies the default Sun Grid Engine cell. To address a Sun Grid
Engine cell qconf uses (in the order of precedence):

The name of the cell specified in the environment variable SGE_CELL,
if it is set.

The name of the default cell, i.e. default.

SGE_DEBUG_LEVEL
If set, specifies that debug information should be written to stderr. In
addition the level of detail in which debug information is generated is
defined.

SGE_QMASTER_PORT
If set, specifies the tcp port on which sge_qmaster(8) is expected to
listen for communication requests. Most installations will use a services
map entry instead to define that port.

SGE_EXECD_PORT If set, specifies the tcp port on which sge_execd(8) is expected to listen
for communication requests. Most installations will use a services map
entry instead to define that port.

SGE_SINGLE_LINE
If set, indicates that long lines should not be broken up using
backslashes. This setting is useful for scripts which expect one entry per
line.

RESTRICTIONS

Modifications to a queue configuration do not affect an active queue, taking effect on
next invocation of the queue (i.e., the next job).

Use qconf online using onworks.net services
