       sge_conf - Grid Engine bootstrap file

DDEESSCCRRIIPPTTIIOONN
       _b_o_o_t_s_t_r_a_p  contains  parameters that are needed for the startup of Grid
       Engine components.  It is created during the sge_qmaster  installation.
       Modifying _b_o_o_t_s_t_r_a_p in a running system is not supported.


FFOORRMMAATT
       The paragraphs that follow provide brief descriptions of the individual
       parameters that compose the bootstrap configuration for a  Grid  Engine
       cluster:

   aaddmmiinn__uusseerr
       Administrative  user  account used by Grid Engine for all internal file
       handling (status spooling, message logging, etc.). Can be used in cases
       where the root account does not have the corresponding file access per-
       missions (e.g. on a shared file system without global  root  read/write
       access).

       Changing  the aaddmmiinn__uusseerr parameter set at installation time is not sup-
       ported in a running system. Changing it manually on a shut-down cluster
       is  possible,  but if access to the Grid Engine spooling area is inter-
       rupted, this will result in unpredictable behavior.

       The aaddmmiinn__uusseerr parameter has  no  default  value,  but  instead  it  is
       defined during the master installation procedure.

   ddeeffaauulltt__ddoommaaiinn
       Only  needed if your Grid Engine cluster covers hosts belonging to more
       than a single DNS domain. In this case it can be used if your  hostname
       resolving yields both qualified and unqualified hostnames for the hosts
       in one of the DNS domains.  The value of ddeeffaauulltt__ddoommaaiinn is appended  to
       the  unqualified  hostname  to  define a fully qualified hostname.  The
       ddeeffaauulltt__ddoommaaiinn parameter will have no effect if iiggnnoorree__ffqqddnn is  set  to
       "true".

       Changing   the ddeeffaauulltt__ddoommaaiinn parameter set at installation time is not
       supported in a  running  system.  The  default  for  ddeeffaauulltt__ddoommaaiinn  is
       "none", in which case it will not be used.

   iiggnnoorree__ffqqddnn
       Ignore  fully  qualified  domain name component of hostnames. Should be
       set if all hosts belonging to a Grid Engine cluster are part of a  sin-
       gle  DNS  domain.  It  is  switched  on if set to either "true" or "1".
       Switching it on may solve problems with load reports due  to  different
       hostname resolutions across the cluster.

       Changing the iiggnnoorree__ffqqddnn parameter set at installation time is not sup-
       ported in a running system. The default for iiggnnoorree__ffqqddnn is "true".

   ssppoooolliinngg__mmeetthhoodd
       Defines how _s_g_e___q_m_a_s_t_e_r(8) writes  its  configuration  and  the  status
       information of a running cluster.

       The available spooling methods are _b_e_r_k_e_l_e_y_d_b and _c_l_a_s_s_i_c.

   ssppoooolliinngg__lliibb
       The  name  of  a  shared  library  containing the ssppoooolliinngg__mmeetthhoodd to be
       loaded at _s_g_e___q_m_a_s_t_e_r(8) initialization time.  The extension character-
       izing  a  shared  library  (.so,  .sl, .dylib etc.) is not contained in
       ssppoooolliinngg__lliibb.

       If ssppoooolliinngg__mmeetthhoodd was set to _b_e_r_k_e_l_e_y_d_b  during  installation,  ssppooooll--
       iinngg__lliibb  is set to _l_i_b_s_p_o_o_l_b. If _c_l_a_s_s_i_c was chosen as ssppoooolliinngg__mmeetthhoodd,
       ssppoooolliinngg__lliibb is set to _l_i_b_s_p_o_o_l_c.

       Not all operating systems allow the dynamic loading  of  libraries.  On
       these platforms a certain spooling method (default: berkeleydb) is com-
       piled into the binaries and the parameter ssppoooolliinngg__lliibb will be ignored.


   ssppoooolliinngg__ppaarraammss
       Defines parameters to the chosen spooling method.

       Parameters  that  are needed to initialize the spooling framework, e.g.
       to open database files or to connect to a certain database server.

       The  spooling  parameters  value  for  spooling  method  _b_e_r_k_e_l_e_y_d_b  is
       [rpc_server:]database  directory,  e.g.  /sge_local/default/spool/qmas-
       ter/spooldb for spooling to  a  local  filesystem,  or  myhost:sge  for
       spooling over a Berkeley DB RPC server.

       For spooling method _c_l_a_s_s_i_c the spooling parameters take the form <com-
       mon_dir>;<qmaster     spool     dir>,      e.g.       /sge/default/com-
       mon;/sge/default/spool/qmaster

   bbiinnaarryy__ppaatthh
       The  directory  path  where the Grid Engine binaries reside. It is used
       within Grid Engine components to locate and startup other  Grid  Engine
       programs.

       The path name given here is searched for binaries as well as any direc-
       tory below with a directory name equal to the current operating  system
       architecture.  Therefore, /usr/SGE/bin will work for all architectures,
       if the corresponding  binaries  are  located  in  subdirectories  named
       aix43, cray, lx24-x86, hp11, irix65, tru64, sol-sparc, etc.

       The default location for the binary path is <SGE_ROOT>/bin


   qqmmaasstteerr__ssppooooll__ddiirr
       The  location  where  the  master  spool  directory  resides.  Only the
       _s_g_e___q_m_a_s_t_e_r(8) and _s_g_e___s_h_a_d_o_w_d(8) need to have access  to  this  direc-
       tory.   The  master  spool  directory  -  in particular the job_scripts
       directory and the messages log file - may become quite large  depending
       on  the size of the cluster and the number of jobs. Be sure to allocate
       enough disk space and regularly clean off the log  files,  e.g.  via  a
       _c_r_o_n(8) job.

       Changing  the  qqmmaasstteerr__ssppooooll__ddiirr  parameter set at installation time is
       not supported in a running system.

       The   default   location   for   the   master   spool   directory    is
       $SGE_ROOT/$SGE_CELL/spool/qmaster.


   pprroodduucctt__mmooddee
       The  product  mode defines the set of features the installed cluster is
       using.

       Both the basic product modes sge (Grid Engine standard mode) and  sgeee
       (Grid  Engine  Enterprise Edition) as well as additional features (AFS,
       DCE, KERBEROS, RESERVED_PORT security model, CSP  security  model)  are
       specified by this parameter.
