SGE_PASSWD(1) Sun Grid Engine User Commands SGE_PASSWD(1)NAME
sgepasswd - Modify the Sun Grid Engine password file of Sun Grid Engine
SYNTAX
sgepasswd [[ -D domain ] -d user ]
sgepasswd [ -D domain ] [ user ]
DESCRIPTION
sgepasswd modifies the Sun Grid Engine password file sgepasswd(5).
This file contains a list of usernames and their windows password in encrypted form. sge_execd(8) and sge_shepherd(8) on hosts running Mi-
crosoft Windows as operating systems use this information to start jobs for a certain user.
Each user can use the sgepasswd application to add a new entry for the own user account. It is also possible to change the stored password
with sgepasswd as far as the user knows the old one.
The root user additionally has the permission to change the password entries for other user accounts. Root can also delete existing
entries.
The sgepasswd binary is only available on non-Windows hosts.
OPTIONS -D domain
Per default sgepasswd will add/modify the current Unix username without domain specification. This switch can be used to add a
domain specification in front of the current user name. Consult your Microsoft Windows documentation to get more information about
domain users.
-d user
Only root can use this parameter to delete entries from the sgepasswd(5) file.
-help Prints a listing of all options.
ENVIRONMENTAL VARIABLES
SGE_CERTFILE Specifies the location of public key file. Per default sgepasswd will use the file $SGE_ROOT/$SGE_CELL/com-
mon/sgeCA/certs/cert.pem
SGE_KEYFILE If set, specifies the location of the private key file. Default is /var/sgeCA/port${SGE_QMASTER_PORT}/${SGE_CELL}/pri-
vate/key.pem
SGE_RANDFILE If set, specifies the location of the seed used to create encrypted versions of user passwords. Default is
/var/sgeCA/port${SGE_QMASTER_PORT}/${SGE_CELL}/private/rand.seed

SGE_QMASTER(8) Sun Grid Engine Administrative Commands SGE_QMASTER(8)NAME
sge_qmaster - Sun Grid Engine master control daemon
SYNOPSIS
sge_qmaster [ -help ]
DESCRIPTION
sge_qmaster controls the overall Sun Grid Engine behavior in a cluster.
OPTIONS -help Prints a listing of all options.
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 sge_qmaster 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 infor-
mation 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 for the service "sge_qmaster" 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 for the service "sge_execd" instead to define that port.
RESTRICTIONS
sge_qmaster is usually started from root on the master or shadow master machines of the cluster (refer to the Sun Grid Engine Installation
and Administration Guide for more information about the configuration of shadow master hosts). If started by a normal user, a master spool
directory must be used to which the user has read/write access. In this case only jobs being submitted by that same user are handled cor-
rectly by the system.
