Patch requirements and patch matrix for N1 Grid Engine 6 packages
-----------------------------------------------------------------
 
   The patches below update a N1 Grid Engine 6 distribution to N1 Grid
   Engine 6 Update 8 (N1GE 6.0u8). The "-help" output of most commands will
   print a version string "N1GE 6.0u8" after applying the patch.
 
   All packages of a N1 Grid Engine 6 distribution must have the same patch
   level (exception for ARCo - see requirements for ARCo in the ARCo patches
   README's). Please refer to the patch matrix below which updates the
   distribution to most recent patch level.
 
   It is not supported and possible to mix different patch levels of
   binaries and the "common" package in a single N1 Grid Engine cluster.

   Patch Installation
   ------------------
 
   NOTE: This patch requires that you update your Berkeley DB database files
         if you are upgrading from N1GE 6.0u1 or 6.0.  Please read the full
         notes when applying this patch.
 
   These installation instructions assume that you are running a homogenous
   N1 Grid Engine cluster (called "the software") where all hosts share the
   same directory for the binaries. If you are running the software in a
   heterogenous environment (mix of different binary architectures), you
   need to apply the patch installation for all binary architectures as well
   as the "common" and "arco" packages. See the patch matrix above for
   details about the available patches.
 
   If you installed the software on local filesystems, you need to install
   all relevant patches on all hosts where you installed the software
   locally.
 
   By default, there should by no running jobs when the patch is installed. 
   There may pending batch jobs, but no pending interactive jobs (qrsh,
   qmake, qsh, qtcsh).
 
   It is possible to install the patch with running batch jobs. To avoid a
   failure of the active 'sge_shepherd' binary, it is necessary to move the
   old shepherd binary (and copy it back prior to the installation of the
   patch).
 
   You can not install the patch with running interactive jobs, 'qmake' jobs
   or with running parallel jobs which use the tight integration support
   (control_slaves=true in PE configuration is set).
 
   A. Stopping the N1 Grid Engine cluster to start jobs
   ----------------------------------------------------
 
   Disable all queues so that no new jobs are started:
 
      # qmod -d '*'
 
   Optional (only needed if there are running jobs which should continue to
   run when the patch is installed):
 
      # cd $SGE_ROOT/bin
      # mv <arch>/sge_shepherd <arch>/sge_shepherd.sge60
 
   It is important that the binary is moved with the "mv" command. It should
   not be copied because this could cause the crash of an active shepherd
   process which is currently running job when the patch is installed.
 
   B. Shutting down the N1 Grid Engine daemons
   -------------------------------------------
 
   You need to shutdown (and restart) the qmaster and scheduler daemon and
   all running execution daemons.
 
   Shutdown all your execution hosts. Login to all your execution hosts and
   stop the execution daemons:
 
      # /etc/init.d/sgeexecd softstop
 
   Then login to your qmaster machine and stop qmaster and scheduler:
 
      # /etc/init.d/sgemaster stop
 
   Now verify with the 'ps' command that all N1 Grid Engine daemons on all
   hosts are stopped. If you decided to rename the 'sge_shepherd' binary so
   that running jobs can continue to run during the patch installation, you
   must not kill the 'sge_shepherd' binary (process).
 
   C. Installing the patch and restarting the software
   ---------------------------------------------------
 
   Now install the patch by installing the patch with "patchadd" or by
   unpacking the 'tar.gz' files included in this patch as outlined above.
 
 
      Berkeley DB database update needed
      ----------------------------------
 
      NOTE: This update is *not* needed if you already installed N1GE 6.0u3
            or higher. The update is only needed if you are upgrading from
            N1GE 6.0u2 or earlier.
 
      After installing this patch, and before restarting your cluster you
      need to update your Berkeley DB (BDB) database in the following cases:
 
         - you choose the BDB spooling option (not needed for classic
           spooling) either locally or with the BDB RPC option, and you are
           upgrading your cluster for N1 Grid Engine 6.0 or 6.0u1 to N1 Grid
           Engine 6.0u2 or higher
 
      1. For safety reasons, please make a full backup of your existing
         configuration. To perform a backup use this command
 
            % inst_sge -bup
 
      2. Upgrade your BDB database. This is done as follows:
 
           % inst_sge -updatedb
 
      Restarting the software
      -----------------------
 
      Please login to your qmaster machine and execution hosts and enter:
 
         # /etc/init.d/sgemaster
         # /etc/init.d/sgeexecd
 
      After restarting the software, you may again enable your queues:
 
         # qmod -e '*'
 
      If you renamed the shepherd binary, you may safely delete the old
      binary when all jobs which where running prior the patch installation
      have finished.
 
 
   New functionality delivered with N1GE 6.0 Update 7
   --------------------------------------------------
 
   1. Reworked "qstat -xml" output
   -------------------------------
 
   The schema for "qstat -xml" and the "qstat -xml" output have been
   reworked to ensure consistency between them and easy parsing of them via
   JAXB. The most noticeable change will the date output. It follows now the
   XML datetime format.
 
   2. Reworked PE range matching algorithm in the scheduler
   --------------------------------------------------------
 
   The PE range matching algorithm is now adaptable and learns from the past
   decisions. This will lead to a much faster scheduling decision in case of
   pe-ranges. This can be controlled by a new scheduling configuration
   parameter: SELECT_PE_RANGE_ALG.  It allows to restore the old behavior. 
 
   See sge_conf(5) for more information.
 
   3. New monitoring feature in qmaster
   ------------------------------------
 
   The monitoring allows to get detailed statistics what the qmaster
   threads are doing and how busy they are.  The statistics can be accessed
   via "qping -f" or from the qmaster messages file.  The feature is controlled
   by two qmaster configuration parameters:
 
      MONITOR_TIME          specifying the time interval for the statistics
      LOG_MONITOR_MESSAGE   enables/ disables the logging of the monitoring
                            messages into the qmaster messages file.
 
   See sge_conf(5) for more information.
 
   4. New parameter for specialized job deletion
   ---------------------------------------------
 
   A new "execd_param" (configured in the global cluster configuration):
 
      ENABLE_ADDGRP_KILL=true
 
   can be configured to enable addition code within the execution host to
   delete jobs. If this parameter is set then the supplementary group id's
   are used to identify all processes which are to be terminated when a job
   should be deleted. It has only effect for following architectures:
 
      sol*
      lx*
      osf4
      tru64
 
   See sge_conf(5) under "gid_range" for more information.
 
   5. New reporting parameter to control accounting file flush time
   ----------------------------------------------------------------
 
   A new reporting parameter, "accounting_flush_time", controls the flush
   period for the accounting file. Previously, both the accounting and
   reporting files were flush at the same interval. Now they can be set
   independently. Additionally, buffering of the accounting file can now be
   disabled, allowing accounting data to be written to the accounting file
   as soon as it becomes available.
 
   See sge_conf(5) for more information.
 
 
   New functionality delivered with N1GE 6.0 Update 6
   --------------------------------------------------
 
   1. Berkeley DB database tools are included in the distribution
   --------------------------------------------------------------
 
   All Berkeley DB database tools are now part of the N1 Grid Engine
   distribution (not for Microsoft Windows platform)
 
     db_archive 
     db_checkpoint
     db_deadlock 
     db_dump
     db_load
     db_printlog
     db_recover
     db_stat
     db_upgrade
     db_verify
 
   The HTML documentation for these tools is part of the "common" patch and
   can be found in:
 
     <sge_root>/doc/bdbdocs
 
 
   New functionality delivered with N1GE 6.0 Update 4
   --------------------------------------------------
 
   1. New "qconf -purge" option
   ----------------------------
 
   "qconf -purge" deletes all hosts or hostgroups settings from a cluster
   queue. This facilitates the uninstallation of host or hostgroups. See
   qstat(1) for more a description how to use this parameter
 
 
   2. Berkeley DB spooling on NFSv4 under Solaris 10 supported
   -----------------------------------------------------------
 
   The Berkeley DB database now can be installed on a NFSv4 mounted
   filesystem on Solaris 10.
 
   For performance reasons it is recommended to use NFSv4 BDB spooling only
   when the NFSv4 mount provides an excellent high speed connection to the
   file server.
 
   3. Execd installation in Solaris 10 zones supported
   ---------------------------------------------------
 
   The execution daemon installation in Solaris 10 zones is supported. If an
   execution daemons is installed in the global zone and in local zones you
   need to ensure that the additional group id range (-> "gid_range" in
   cluster configuration) from the global zone and the local zones does not
   overlap. Local zones may use the same additional group id range in the
   same host.
 
   4. Faster execution daemon reconnect in CSP mode
   ------------------------------------------------
 
   The Certificate Security Protocol (CSP) has been reworked and now is fully
   integrated in the communication library layer. The allows a faster
   reconnect of execution daemons after qmaster or execution daemon restart.
 
 
   New functionality delivered with N1GE 6.0 Update 2
   --------------------------------------------------
 
   1. Avoid setting of LD_LIBRARY_PATH; inherited job environment
   --------------------------------------------------------------
 
   There are two new "execd_params" (defined in the global or local cluster
   configuration) which control the environment inherited by a job:
 
      SET_LIB_PATH
      INHERIT_ENV
 
   By default, SET_LIB_PATH is false and INHERIT_ENV is true.  If
   SET_LIB_PATH is true and INHERIT_ENV is true, each job will inherit the
   environment of the shell that started the execd, with the N1GE lib
   directory prepended to the lib path.  If SET_LIB_PATH is true and
   INHERIT_ENV is false, the environment of the shell that started the execd
   will not be inherited by jobs, and the lib path will contain only the
   N1GE lib directory.  If SET_LIB_PATH is false and INHERIT_ENV is true,
   each job will inherit the environment of the shell that started the execd
   with no additional changes to the lib path.  If SET_LIB_PATH is false and
   INHERIT_ENV is false, the environment of the shell that started the execd
   will not be inherited by jobs, and the lib path will be empty. 
   Environment variables which are normally overwritten by the shepherd,
   such as PATH or LOGNAME, are unaffected by these new parameters.
 
   2. DRMAA Java[TM] language binding delivered with this patch
   ------------------------------------------------------------
 
   The DRMAA Java language binding is now available. The DRMAA Java language
   binding library and documentation is contained in the patch for the
   "common" package.
 
   3. New qstat options to optimize memory overhead and speed of qstat
   -------------------------------------------------------------------
 
   The qstat client command has been enhanced to reduce the overall amount
   of memory which is requested from the qmaster. To enable these changes it
   is necessary to change the qstat default behavior. This is possible by
   defining a cluster-global or user-specific sge_qstat file. More
   information can be found in sge_qstat(5) manual page. In addition two new
   qstat options ("-u" and "-s") have been introduced to be used with the
   sge_qstat default file. Find more information in qstat(1).
 
   4. Tuning parameter for sharetree spooling
   ------------------------------------------
 
   A new "qmaster_param" (configured in the global cluster configuration):
 
     STREE_SPOOL_INTERVAL=<time>
 
   can be configured to control the interval for how often the sharetree
   usage is spooled. The interval can be set to any time in the following
   formats:
 
       HH:MM:SS or 
       <int>
 
   E.g.:
 
      STREE_SPOOL_INTERVAL=0:05:00
      STREE_SPOOL_INTERVAL=300
 
   This parameter is a tuning parameter only. It has the biggest effect on a
   system using classic spooling and bigger sharetrees and a slow
   filesystem.
