McIDAS-XCD
Fastrack Version 2008a
Software and Instructions
McIDAS-XCD
version 2008a is available here as a Fastrack release with several
modifications made since the 2008 upgrade. These changes include:
- updates to the Terminal Aerodrome Forecast (TAF) decoder to accommodate
the format change for the switch from 24-hour to 30-hour
TAFs that is scheduled for 05 November 2008
- corrections to the Ship/Buoy decoder to fix a problem introduced
in the 2008 upgrade that resulted in anomalous data in Ship/Buoy
MD files
- fixes to ensure GRIB2 database entries are not missing level
units where applicable
- updates for the new Multi-Grid Wave Model (MGWM) and Global Forecast
System (GFS) Alaska region data now available in GRIB2 format on
the NOAAPORT datastream
- fixes to correct improper handling of 5-digit string representation
on 32-bit machines (e.g., 10000 m above sea level)
- use of the station database file (STNDB.CORE)
that was updated in McIDAS-X 2008a to include the negative sign
in the latitude of Southern Hemisphere stations that are
within one degree of the equator, and to include the negative sign
in the longitude of Eastern Hemisphere stations that
are within one degree of the Greenwich Meridian; plus the addition
of four new C-MAN stations
Please keep in mind that McIDAS-XCD 2008a has not been thoroughly
tested. If you elect to
install 2008a, we ask that you notify the McIDAS
Help Desk if
you encounter any bugs. Please be sure to mention that you are running
version 2008a.
Also note that if you plan to upgrade to 2008a from a version earlier
than 2008 (e.g., 2007), you must first read and perform the required
actions in the document titled McIDAS-XCD Version
2008 Upgrade Procedure, June 2008 that was included in your site's
2008 upgrade package.
***** Important!!! *****
You must install McIDAS-X
2008a before you install McIDAS-XCD 2008a because
it has changes to the station database and GRIB servers and files
that are needed in McIDAS-XCD 2008a.
To obtain and install McIDAS-XCD 2008a, complete the following steps.
- Download the following files to the ~oper/mcidas directory
on your McIDAS-XCD workstation.

- If you are installing McIDAS-XCD for the first time on the workstation, go to the
McIDAS-XCD Administrator's Guide's Installing
McIDAS-XCD 2008 for the First Time and complete its instructions, but substitute "2008a"
wherever "2008" appears. After installing -XCD for the first time, if
you want to make additional GRIB2 dataset changes (i.e., change or add datasets), see the
Creating a GRIB2 Dataset page.
If you are installing McIDAS-XCD Fastrack version 2008a on a workstation that already has version 2008
installed, complete the steps below.
- If -XCD is running in the foreground, turn it off by exiting the McIDAS session and wait
until all ingestors and data monitors have exited. From the McIDAS Text and Command window,
If -XCD is running in the background, stop the session by running the following
command from an oper xterm.
- From an oper xterm, build and install McIDAS-XCD 2008a
using the same compilers (vendor or gcc/g77) and optional flag (-noopt and
-mysql) settings that were used to build McIDAS-X 2008a. You must use the
same compilers and optional flag settings for both the McIDAS-X and McIDAS-XCD builds.
If you are using vendor compilers,
Type: sh ./xcd2008a.sh -v flags build
If you are using gcc/g77 compilers,
Type: sh ./xcd2008a.sh -gcc flags build
where flags is zero, one or both
of the two optional flags described below.
- The -noopt flag is used to build McIDAS-XCD with no optimization.
If you don't specify this -noopt flag, McIDAS-XCD is built using the
default optimization: -O2 for builds with vendor compilers and -O1 for builds with gcc/g77.
- The -mysql flag is used to build McIDAS-XCD using the MySQL database
libraries. Use this flag if this workstation will be serving real-time GRIB files from the NOAAPORT data stream and you
have installed and want to use a MySQL database to make the GRIB data access faster for your McIDAS-X clients/users.
If the database is in a non-standard install location, specify the flag as
-mysql=directory, where
directory is the root MySQL install directory.
Remember, the -mysql flag must be specified when building both McIDAS-X
and McIDAS-XCD.
When the script xcd2008a.sh is finished, you will see the message below.
McIDAS-XCD binaries built correctly |
- Run the script below to install the new executable code and a subset of the replaceable McIDAS-XCD
data files for your workstation.
Type: sh ./xcd2008a.sh cutover
When the script is finished, you will see the message below.
McIDAS-XCD package cutover is now complete |
- As user oper start a McIDAS-X session and run the
command below to recreate the GROUPS.DAT and
COUNTRY.DAT files so they contain the station database changes included
in McIDAS-X Fastrack 2008a.
When completed, exit the McIDAS-X session.
- Switch to user mcadde
(with command su mcadde), then start
a McIDAS-X session and run the command below to recreate the GROUPS.DAT
and COUNTRY.DAT files in the mcadde
account so they contain the station database changes included in McIDAS-X Fastrack 2008a.
- While still logged is as user mcadde make a backup copy of
your RESOLV.SRV file (e.g., cp RESOLV.SRV RESOLV.SRV.BAK) then run the command below to
add the new MGWM and GFS GRIB2 datasets to the RESOLV.SRV file.
When completed, exit the McIDAS-X session.
- Switch to user mcidas (with
command su mcidas) and run the script
below from the ~oper/mcidas directory to
install the new ADDE server executable code in the mcidas account.
Type: sh ./xcd2008a.sh install addeservers
- Run the exit command twice
to exit from user mcidas and then from user mcadde.
You should now be logged in as user oper.
- Restart McIDAS-XCD. To do so from the foreground, start a McIDAS-X session from the oper account
and run the command below from the McIDAS Text and Command window,
To restart -XCD in the background, run the following command from an oper xterm.
This concludes the McIDAS-XCD Fastrack version 2008a installation procedure. If you would like to
modify the configuration of your McIDAS-XCD workstation, go to the McIDAS-XCD
Administrator's Guide's Configuring McIDAS-XCD.
