       sge_shadowd - Grid Engine Enterprise Edition shadow master daemon


       sge_shadowd is a "light weight" process which can be run on the so called
       shadow master hosts in a Grid Engine Enterprise Edition cluster to detect
       failure of the current Grid Engine Enterprise Edition master daemon
       sge_qmaster(8) and to start-up a new sge_qmaster(8) on the host on which
       the sge_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 <sge_root>/<cell>/common
       as well as to the master daemon spool directory (Default
       <sge_root>/<cell>/spool/qmaster).  The shadow master hosts need to be
       contained in the file <sge_root>/<cell>/common/shadow_masters.

       sge_shadowd may only be started from root.

       SGE_ROOT       Specifies the location of the Grid Engine Enterprise
                      Edition standard configuration files.

       SGE_CELL       If set, specifies the default Grid Engine Enterprise
                      Edition cell. To address a Grid Engine Enterprise Edition
                      cell sge_shadowd 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.

                      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.

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

       COMMD_HOST     If set, specifies the host on which the particular
                      sge_commd(8) to be used for Grid Engine Enterprise Edition
                      communication of the sge_shadowd client resides.  Per
                      default the local host is used.

                       Default configuration directory
                       Shadow master hostname file.
                       Default master daemon spool directory
