       bootstrap - Sun Grid Engine bootstrap file


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


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

       Administrative user account used by Sun 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 permissions (e.g.  on  a  shared  file  system  without
       global root read/write access).

       Being  a parameter set at installation time changing admin_user in a running system is not
       supported. Changing it manually on a shut-down cluster is possible, but if access  to  the
       Sun Grid Engine spooling area is interrupted, this will result in unpredictable behavior.

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

       Only needed if your Sun 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
       default_domain  is  appended  to  the  unqualified  hostname  to  define a fully qualified
       hostname.  The default_domain parameter will have no  effect  if  ignore_fqdn  is  set  to

       Being  a parameter set at installation time changing default_domain in a running system is
       not supported. The default for default_domain is "none", in which  case  it  will  not  be

       Ignore  fully  qualified  domain  name  component of hostnames. Should be set if all hosts
       belonging to a Sun Grid Engine cluster are part of a single 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.

       Being a parameter set at installation time changing ignore_fqdn in a running system is not
       supported. The default for ignore_fqdn is "true".

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

       The available spooling methods are berkeleydb and classic.

       The name of a shared library containing the spooling_method to be loaded at sge_qmaster(8)
       initialization  time.   The  extension  characterizing  a shared library (.so, .sl, .dylib
       etc.) is not contained in spooling_lib.

       If spooling_method was set to berkeleydb  during  installation,  spooling_lib  is  set  to
       libspoolb, if classic was chosen as spooling_method, spooling_lib is set to libspoolc.

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

       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  berkeleydb  is  [rpc_server:]database
       directory,   e.g.   /sge_local/default/spool/qmaster/spooldb   for  spooling  to  a  local
       filesystem, or myhost:sge for spooling over a Berkeley DB RPC server.

       For spooling method classic the spooling parameters take  the  form  <common_dir>;<qmaster
       spool dir>, e.g.  /sge/default/common;/sge/default/spool/qmaster

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

       The path name given here is searched for binaries as well as any directory  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

       The  location  where  the  master  spool  directory  resides.  Only the sge_qmaster(8) and
       sge_shadowd(8) need to have access to this directory.  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 cron(8) job.

       Being  a parameter set at installation time changing qmaster_spool_dir in a running system
       is not supported.

       The default location for the master spool directory is <sge_root>/<cell>/spool/qmaster.

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

       Possible security mode settings  are  none,  afs,  dce,  kerberos,  csp.   (no  additional
       security, AFS, DCE, KERBEROS, CSP security model).

       The number of listener threads (defaults set by installation).

       The number of worker threads (defaults set by installation).

       The  number  of  scheduler threads (allowed: 0-1, default set by installation: 1, off: 0).
       (see qconf(1) -kt/-at option)

       The number of jvm threads (allowed: 0-1, default set by installation, off: 0).
