[1mNAME[0m
       sge_conf - Grid Engine bootstrap file

[1mDESCRIPTION[0m
       [4mbootstrap[24m  contains  parameters that are needed for the startup of Grid
       Engine components.  It is created during the sge_qmaster  installation.
       Modifying [4mbootstrap[24m in a running system is not supported.


[1mFORMAT[0m
       The paragraphs that follow provide brief descriptions of the individual
       parameters that compose the bootstrap configuration for a  Grid  Engine
       cluster:

   [1madmin_user[0m
       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 [1madmin_user [22mparameter 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 [1madmin_user [22mparameter has  no  default  value,  but  instead  it  is
       defined during the master installation procedure.

   [1mdefault_domain[0m
       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 [1mdefault_domain [22mis appended  to
       the  unqualified  hostname  to  define a fully qualified hostname.  The
       [1mdefault_domain [22mparameter will have no effect if [1mignore_fqdn [22mis  set  to
       "true".

       Changing   the [1mdefault_domain [22mparameter set at installation time is not
       supported in a  running  system.  The  default  for  [1mdefault_domain  [22mis
       "none", in which case it will not be used.

   [1mignore_fqdn[0m
       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 [1mignore_fqdn [22mparameter set at installation time is not sup-
       ported in a running system. The default for [1mignore_fqdn [22mis "true".

   [1mspooling_method[0m
       Defines how [4msge_qmaster[24m(8) writes  its  configuration  and  the  status
       information of a running cluster.

       The available spooling methods are [4mberkeleydb[24m and [4mclassic[24m.

   [1mspooling_lib[0m
       The  name  of  a  shared  library  containing the [1mspooling_method [22mto be
       loaded at [4msge_qmaster[24m(8) initialization time.  The extension character-
       izing  a  shared  library  (.so,  .sl, .dylib etc.) is not contained in
       [1mspooling_lib[22m.

       If [1mspooling_method [22mwas set to [4mberkeleydb[24m  during  installation,  [1mspool-[0m
       [1ming_lib  [22mis set to [4mlibspoolb[24m. If [4mclassic[24m was chosen as [1mspooling_method[22m,
       [1mspooling_lib [22mis set to [4mlibspoolc[24m.

       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 [1mspooling_lib [22mwill be ignored.


   [1mspooling_params[0m
       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  [4mberkeleydb[24m  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 [4mclassic[24m the spooling parameters take the form <com-
       mon_dir>;<qmaster     spool     dir>,      e.g.       /sge/default/com-
       mon;/sge/default/spool/qmaster

   [1mbinary_path[0m
       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


   [1mqmaster_spool_dir[0m
       The  location  where  the  master  spool  directory  resides.  Only the
       [4msge_qmaster[24m(8) and [4msge_shadowd[24m(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
       [4mcron[24m(8) job.

       Changing  the  [1mqmaster_spool_dir  [22mparameter 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.


   [1mproduct_mode[0m
       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.
