Hi there,

I just noticed that the 6.2 man pages speak of "GE_" environment
variables instead of "SGE_" - which ones should I use?  Are both
names equally valid?  I'm a little bit confused, feels like I
have missed something....

Thanks, Erik Soyez.

GE_SHADOWD(8)     Grid Engine Administrative Commands    GE_SHADOWD(8)

NAME
        ge_shadowd - Grid Engine shadow master daemon

SYNOPSIS
        ge_shadowd

DESCRIPTION
        ge_shadowd  is a "light weight" process which can be run on so-
        called shadow master hosts in a Grid Engine cluster  to  detect
        failure  of  the  current  Grid  Engine master daemon, ge_qmasâ
        ter(8), and to start-up a new  ge_qmaster(8)  on  the  host  on
        which  the  ge_shadowd  runs.  If  multiple  shadow daemons are
        active in a cluster, they run a  protocol  which  ensures  that
        only one of them will start-up a new master daemon.

        The   hosts suitable for being used as shadow master hosts must
        have  shared  root   read/write   access   to   the   directory
        $GE_ROOT/$GE_CELL/common  as well as to the master daemon spool
        directory (by  default  $GE_ROOT/$GE_CELL/spool/qmaster).   The
        names  of  the  shadow master hosts need to be contained in the
        file $GE_ROOT/$xQS_NAME_Sxx_CELL/common/shadow_masters.

RESTRICTIONS
        ge_shadowd may only be started by root.

ENVIRONMENT VARIABLES
        GE_ROOT        Specifies the location of the Grid Engine  stanâ
                       dard configuration files.

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

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

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

        GE_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.

        GE_QMASTER_PORT
                       If set, specifies the tcp port on which ge_qmasâ
                       ter(8) is expected to listen  for  communication
                       requests.   Most  installations  will use a serâ
                       vices map entry for  the  service  "sge_qmaster"
                       instead to define that port.

        GE_DELAY_TIME  This  variable  controls  the  interval in which
                       ge_shadowd pauses if a takeover bid fails.  This
                       value  is  used  only  when  there  are multiple
                       ge_shadowd instances and they are contending  to
                       be the master.  The default is 600 seconds.

        GE_CHECK_INTERVAL
                       This variable controls the interval in which the
                       ge_shadowd checks the heartbeat file (60 seconds
                       by default).

        GE_GET_ACTIVE_INTERVAL
                       This  variable  controls  the  interval  when  a
                       ge_shadowd instance tries to take over when  the
                       heartbeat file has not changed.
