Patch Installation Instructions:
--------------------------------

Special Install Instructions:
-----------------------------
 
   Important note if Sun Grid Engine has been installed with openSSL support
   -------------------------------------------------------------------------
 
   If Sun Grid Engine has been installed with openSSL support ("CSP mode")
   prior to SGEEE 5.3p3 (which was linked with openSSL 0.9.6.c), the
   certificates which have been installed with these versions are
   incompatible with certificates installed with SGEEE 5.3p4 or later. All
   such certificates will need to be recreated after installing this patch
   and before restarting Sun Grid Engine. Please refer to the Sun Grid
   Engine Administration and User Manual for how to create new certificates
   with the utility script "sge_ca", which comes with the distribution.
 
   The reason for the incompatibility is a changed field name between
   openSSL version 0.9.6 and 0.9.7 in the certificates, where
   "uniqueIdentifier" has been renamed to "userId".
 
   Note for bug id 5020371 ("sge_shepherd creates world writable files")
   ---------------------------------------------------------------------
 
   If the execution daemon spool directory is located on NFS and the
   execution host machine does not have read/write permissions for user root
   (which is often the case due to security reasons) the shepherd process
   will continue to create some of the files in its job directory with world
   writable permissions. If the NFS client has write permissions the fix
   will be effective without further changes after patch installation.
 
   To make the fix effective it is required to install the execution daemon
   spool directory on a local file system. Also for performance reasons it
   is recommended to install the execution daemon spool directory on a local
   file system.
 
   1. Changing the execution daemon spool directory for all hosts
   simultaneously - there may be no running jobs in the cluster
 
        - shut down qmaster
        - shutdown all execution daemons
        - edit the global cluster configuration file
 
               <sge_root>/<sge_cell>/common/configuration
 
          and change the path to the configuration value
 
               execd_spool_dir
 
        - restart qmaster
        - restart your execution daemons
 
   2. Changing the execution daemon spool directory for each execution host
      individually:
 
        - no jobs may be running on the execution host where the spool
          directory is going to be changed
        - edit the local configuration for this execution host:
 
             % qconf -mconf  <hostname>
 
          and add the local spool directory:
 
             execd_spool_dir  <path_to_exec_spool_directory>
 
        - shutdown and restart the execution daemons
 
   In addition to these notes please read the "Install Instructions" section
   later in this file about requirements when the patch itself can be
   installed.
 
tar.gz Patch Installation:
--------------------------
 
   This patch in 'tar.gz' format cannot be installed with 'patchadd' on Solaris
   systems. The patch is installed by unpacking the 'tar.gz' file(s) in this
   directory in <install_dir>. <install_dir> is usually your <sge_root>
   directory. The installation of this patch later is not visible with the
   "showrev -p" command on Solaris.
 
   This patch later cannot be backed out. You may make a backup copy of the
   files which will be overwritten when this patch is installed.
 
   Please read "Install Instructions" later in this file and carry out
   all steps before you unpack the 'tar.gz' file(s) included in this patch.
 
   This patch in 'tar.gz' format may not be installed if the original
   package has been installed with 'pkgadd' on Solaris. In this case please
   install the available patches for Sun Grid Engine, Enterprise Edition
   from http://sunsolve.sun.com in 'pkgadd' format.
 
   The patch is installed by user root by unpacking the file(s) in the
   directory where the original package has been installed:
 
      # cd <install_dir>
      # gzip -dc <patchid>/<targzfile> | tar xvpf -
 
   After installing the patch you should correct the file permissions if
   your Sun Grid Engine installation is installed as an "admin user" system:
 
      # cd <sge_root>
      # util/setfileperm.sh <adminuser> <admingroup> <sge_root>
 
   where <adminuser> is the username of the "admin_user" of your global
   cluster configuration and <admingroup> is the group which you set during
   your initial installation for the files of your Sun Grid Engine
   distribution.
 
Install Instructions:
---------------------
 
   These installation instructions assume that you are running a homogenous
   Sun Grid Engine cluster where all hosts share the same directory for the
   binaries. If you are running Sun Grid Engine in a heterogenous
   environment (mix of 32-bit and 64-bit binaries for Solaris and/or other
   operating systems) it is only necessary to shutdown the daemons for the
   architecture for which the patch is applied.  If you installed the
   binaries on a local partition, you only need to stop the Sun Grid Engine
   daemons for that host on which you are installing the patch.
 
   By default there may 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 the installation of the
   patch).
 
   In no case it is supported to 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). 
 
 
   Stopping the Sun Grid Engine cluster to start jobs
   --------------------------------------------------
 
   Disable all queues 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.sge53
 
   It is important that the binary is moved with the "mv" command. It may
   not be copied because this could cause a crash of an active shepherd
   process of a running job when the patch is installed.
 
 
   Shutting down Sun Grid Engine qmaster and scheduler
   ---------------------------------------------------
 
   You need to shutdown (and restart) the qmaster and scheduler daemon and
   all execution daemons on all Sun Grid Engine hosts.
 
   Shutdown all your execution hosts. Login to all your execution hosts and 
   stop the 'sge_execd' and 'sge_commd':
 
      # /etc/init.d/rcsge stop
 
   Then login to your qmaster machine and stop 'sge_qmaster', 'sge_schedd', 
   'sge_commd' and if the machine is also an execution host 'sge_execd'
 
      # /etc/init.d/rcsge stop
 
   Now verify with the 'ps' command that all Sun Grid Engine daemons on all
   hosts are stopped. If you decided to rename the shepherd binary that
   running patch job continue to run during the patch installation you may
   not kill the 'sge_shepherd' binary.
 
 
   Installing the patch and restarting Sun Grid Engine
   ---------------------------------------------------
 
   Now please install the patch by unpacking the 'tar.gz' files included in
   this patch as outline above.
 
   After installing the patch you need to restart your cluster. Please login
   to your qmaster machine and enter:
 
      # /etc/init.d/rcsge
 
   Now you should repeat this step on all your execution hosts.
 
   After restarting Sun Grid Engine you may again enable your queues:
 
      # qmod -e '*'
 
   If you renamed the shepherd binary you may safely delete the old binary
   when all jobs finished which where running prior the patch installation.
