[McIDAS #STG-808468]: Conversion of mcidas area to shapefile format

Hi Martha,

Here are the steps provided to another user to setup MySQL use for
GRIB serving in McIDAS.  Note that I assume that you have already
performed the first stem...

1) install the MySQL pieces needed for the McIDAS ADDE GRIB server:

   yum install mysql-server
   yum install mysql-client
   yum install mysql-devel

2) change the password for the MySQL installation to 'xxxxx' as
   per instructions in http://lists.mysql.com/mysql/171366:

   <as 'root'>
   service mysql stop
   mysqld_safe --skip-grant-tables &
   mysql -uroot mysql 
   mysql> use mysql;
   mysql> UPDATE user SET password=PASSWORD("xxxxx") WHERE user="root"; 
   mysql> FLUSH PRIVILEGES;
   -- exit the mysqld_safe invocation

   chkconfig --level 345 mysqld on
   /etc/init.d/mysqld start

At this point, you should be able to create the MySQL database from the
'mcidas' account:

<logged in as 'mcidas'>
cd $MCDATA
decinfo.k SET DMBIN INACTIVE
-- wait until DMBIN has exited

gribadmin makedb    <- you will be asked to provide the password you set above

Assuming that this went smoothly, then you should be able to turn
GRIB filing back on:

decinfo.k SET DMBIN ACTIVE

After GRIB/GRIB2/BUFR processing is working via DMBIN, you will need to
attend to scouring of the model data being received and processed by
DMBIN:

- in a previous setup you ran 'mcxconfig' from the Linux command line
  from the 'mcidas' account.  One of the things that 'mcxconfig' creates
  is an example file of crontab additions that are needed for the 'ldm'
  account.  The items relevant to the model data processing are:

#
# Prune McIDAS-XCD produced BURR/GRIB files
10 08,20 * * * util/xcdscour BUFR 1 /machine/data/ldm/mcidas/bufr
20 08,20 * * * util/xcdscour GRIB 1 /machine/data/ldm/mcidas/grib

  NB: the times that are configured for these invocations to be run, and the
  directory in which to run the scouring will have been set to match
  your setup by the 'mcxconfig' invocation on your XCD processing
  machine.  The entries I show above are relevant to my workstation
  only!

So, you will need to:

- copy the utility '~mcidas/bin/xcdscour' to a directory in your 'ldm'
  account.  Typically, that directory is included in the PATH
  setting for user 'ldm' so you can run the utility by-hand if needed
  or desired.

  The Unidata convention is to create the directories ~ldm/decoders and
  ~ldm/util AND add both of these directories to the PATH of the user
  'ldm'.

- you will need to edit the copy of 'xcdscour' that you just made and 
  make sure that the PATH setting in the file is correct.  The key
  here is to make sure that the 'mysql' executable can be found.

- you will need to insure that the copy of 'xcdscour' that you just made
  is CHMODded to be executable by the user 'ldm':

  <as 'ldm'>
  cd ~ldm
  mkdir util
  cd util
  cp ~mcidas/bin/xcdscour .
  chmod +x xcdscour
  vi xcdscour

NB:

- the scouring of the directories in which GRIB/GRIB2 and BUFR files are
  written and the scouring of the MySQL database can be a heavyweight
  operation (meaning that it might take some time and disrupt fast
  access to the database while running).  It is for this reason that
  it is highly recommended to adjust the times the scouring will run
  to minimize impact on your system

I believe that _if_ there were no snags up to this point, you are
ready to configure the RTGRIBS and RTGRIB2 datasets.  This is done
as follows:

<as 'mcidas'>
cd $MCDATA
batch.k XCDGRIB.BAT
batch.k XCDGRB2.BAT

-- aside: these may have already been created through your running of
   'mcxconfig' previously, but it can't hurt to do it again

One last question:

- Unidata McIDAS-X/-XCD is now up to v2008c, and it will soon be
  bumped up to v2008d.  What addendum are you running?

Cheers,

Tom
