   Below is a list of changes or enhancements which apply to the Sun Grid
   Engine release 5.2 (including subreleases) documentation. These have
   evolved after the 5.2 documentation set already had been finalized.
   Changes which are not listed in the release notes (in 'doc/SGE523RN.pdf')
   are listed here.

   A further source of information is the file 'doc/UPGRADE' if you are
   upgrading from a previous Sun Grid Engine release and the file
   'doc/INSTALL' if you are making a first time installation.


1) Log files
------------

   File space requirements for accounting information, system message and
   error logging:

     * On the master host:

           Between 100KB and 1MB per day depending on the size
           of the CODINE cluster.

     * On each execution host:

           In the order of 20KB per day.

   Methods for log file and accounting file archiving and truncation:

      The concerned files are
     
      <qmaster_spool_dir/messages
      <qmaster_spool_dir>/schedd/messages
      <qmaster_spool_dir>//<hostname>/messages

      <codine_root>/<cell>/common/accounting
      <codine_root>/<cell>/common/statistics

   All these files can be removed without danger during operation of the
   CODINE system. An empty file is recreated if no existing file is found.

   This release comes with a new script template 'util/logchecker.sh' which
   provides a utility script template for rotating and deleting old
   'messages' files, as well as the 'accounting' and 'statistics' file. See
   the file 'doc/logfile-trimming.asc' for a detailed description how to
   customize and use this script.


2) Qmake
--------
  
   Execution of the qmake utility:

   qmake relies on the environment variable ARCH to be set to a string
   describing the architecture of the local host.  It is set by the following
   command (Bourne shell syntax):

      ARCH=`$CODINE_ROOT/util/arch` ; export ARCH

   The corresponding C shell command is

      setenv ARCH `$CODINE_ROOT/util/arch`


3) Load sensor scripts
----------------------

   A new load sensor script for tracking interactive idle term on a local
   host for Solaris has been added. This sample load sensor can be found in

      util/resources/loadsensors/solaris-iidle.sh
