Fastrack Version 2017.2
Software and Instructions
This page contains the software and instructions for installing McIDAS-XCD
version 2017.2, a fully supported Fastrack release. Modifications made
since the previous release (version 2016.2) include:
- Updated the McIDAS-XCD text filer so it can now create raw text files larger
than 2 GB. The previous file size limit was 2^31 bytes, a number that corresponds to
the maximum size of a FORTRAN 4-byte signed integer. The size of the raw text file can now go
up to 2^32 bytes (4 GB). This also required a fix to the STATDISP module to properly display the
larger file size.
- Added several fixes and enhancements to the SFCHOURLY decoder. The updates
include allowing hourly specials to go up to 40 minutes after the top of the hour, and retaining
high accuracy temperature and dewpoint readings if a subsequent report that does not have the
high accuracy readings is received. The change to allow hourly specials to go up to 40 minutes
after the top of the hour was made because the decoder was missing some station readings for
North Carolina at that time.
- Updated the file XCDNOAAPORTGRID.BAT to add 64 new RTGRIDS datasets. See steps 7,
8 and 9 below for the instructions to complete this procedure, and see the xcd_README_2017.2 file
for the complete list of datasets added and removed from the RTGRIDS datasets.
- Updated the station database (file STNDB.CORE) in McIDAS-X 2017.2 to include
56 new Synoptic stations, 28 in Australia and 28 in Antarctica, as supplied by AMRC. Also added or
updated several METAR and TAF stations.
McIDAS-XCD 2017.2 is a fully supported Fastrack release. This means that the software is fully
supported by SSEC, and that each change to the software has been tested on the supported system
configurations. If you elect to install 2017.2, we ask that you notify the
McIDAS Help Desk if you
encounter any bugs. Please be sure to mention that you are running version 2017.2.
Also note that if you plan to upgrade to 2017.2 from a version earlier than the previous release
(2016.2), you must first read and perform any required actions in the release documents for each
of the versions you skipped so you know about their major changes and any required actions in the
interim. For example, if you are upgrading from version 2014.1 to 2017.2, you must first read and
perform the required actions in the release documents for versions 2015.2 and 2016.2 before
proceeding to 2017.2. See the past
versions page for links to those and other materials from past versions.
Obtaining McIDAS-XCD 2017.2
As user oper download the following files to the ~oper/mcidas
directory on your McIDAS‑XCD workstation.
|| shell script that installs the McIDAS-XCD software (right click to download)
||compressed tar file that contains all source and data files
||information to review before installation
And as user mcidas download the following file to the ~mcidas directory
on your McIDAS‑XCD workstation. This tar file contains updates to McIDAS-X 2017.2 that are
required for McIDAS-XCD 2017.2. They will be installed during step 2 of the instructions below.
|| tar file containing updated versions of McIDAS-X modules grib2NavLookup.txt,
grib2NCEPModels.txt, grib2Parameters.txt and mcwrite.c
that are required for McIDAS-X 2017.2
Installing McIDAS-XCD 2017.2
Note: You must install McIDAS-X
2017.2 on the workstation before you install McIDAS-XCD 2017.2. Then continue
with the appropriate set of instructions, as described below.
If you are installing McIDAS-XCD for the first time on the workstation, go to the McIDAS-XCD
Installing McIDAS-XCD 2017.2 for the First Time and complete its instructions. (Use those
instructions rather than those below.)
If you are installing McIDAS-XCD Fastrack version 2017.2 on a workstation that already has a
previous version of McIDAS-XCD installed, complete the steps below.
- At a Unix prompt as user oper, stop McIDAS-XCD and then LDM by running the
commands below in order.
Type: xcdadmin stop
Type: ldmadmin stop
- As user mcidas, uncompress the mcx_xcd_2017.2_Addendum.tar
file that was downloaded in the Obtaining McIDAS-XCD 2017.2 section above. As instructed there, the
tar file must be in the ~mcidas directory and be owned by user mcidas.
Type: cd ~mcidas
Type: tar xvf mcx_xcd_2017.2_Addendum.tar
The commands above copy the mcwrite.c file to the
/home/mcidas/mcidas2017.2/src directory and the three grib2*.txt files
to the /home/mcidas/mcidas2017.2/data directory. The previous versions of the files (from
McIDAS-X 2017.2) are overwritten by these new/updated versions.
Next, do the McIDAS-X 2017.2 make procedure to rebuild the mcwrite.c
dependencies. Use the same settings for optional flags -noopt and
-mysql as were used to build McIDAS-X 2017.2 when you previously
Type:sh ./mcidas2017.2.sh flags make
When the rebuild is done ("McIDAS-X make completed normally" is
displayed) do the McIDAS-X 2017.2 install procedure to complete the updates to the software packaged in the
Type: sh ./mcidas2017.2.sh install
- As user oper,
run the script below from the ~oper/mcidas
directory to build and install McIDAS-XCD 2017.2 using the same settings for optional
flags -noopt and -mysql
as were used to build McIDAS-X 2017.2. You must use the same compilers and optional flag
settings for both the McIDAS-X and McIDAS-XCD builds.
Type: sh ./xcd2017.2.sh flags build
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: -O1 for builds with
- 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 xcd2017.2.sh
is finished, you will see the message below.
McIDAS-XCD binaries built correctly
- As user oper, run the script
below from the ~oper/mcidas
directory to install the new executable code and a subset of the replaceable McIDAS-XCD
data files for your workstation.
Type: sh ./xcd2017.2.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 two commands below. The first command (BATCH REGROUP.BAT)
recreates the GROUPS.DAT and
COUNTRY.DAT files so they contain the station
database changes included in McIDAS-X Fastrack 2017.2. The second command
(BATCH REBILDRAP.BAT) rebuilds the Rapid Access Pointer files so they
include the same station database changes and rebuilds the Rapid Access Text files. Note
that running the second command erases the previous content of the *.RAP
and *.RAT files, so they will contain only new data. That means that
the user commands MOSRPT, OBSRPT, RAOBRPT, SFCRPT, SYNRPT and TAFRPT will not be able to
access any data from prior to McIDAS-XCD being restarted (last step below).
Type: BATCH REGROUP.BAT
Type: BATCH REBILDRAP.BAT
- As user mcadde, 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 2017.2.
- As user mcadde, make a backup
copy of your RESOLV.SRV file (e.g., cp RESOLV.SRV RESOLV.SRV.BAK)
in preparation of adding the restructured RTGRIDS/* datasets in steps 8 and 9 below.
- In the McIDAS-X session started as user mcadde
in step 6 above, run the command below to remove the obsolete and/or redefined RTGRIDS/* datasets.
Type: BATCH RMXCDGRIB2017_2.BAT CONTINUE=YES
- In the McIDAS-X session started as user mcadde
in step 6 above, run the command below to update the RTGRIDS/* datasets so they
contain the data currently available over the NOAAPORT WMO and NGRID feeds.
Type: BATCH XCDNOAAPORTGRID.BAT
As user mcidas, run the script
below from the ~oper/mcidas
directory to install the new ADDE server executable code in the
- The XCDADDE.BAT file, which is optionally run to create the default ADDE datasets, includes
XCDNOAAPORTGRID.BAT among the batch files it runs. See
Configuring the Default ADDE Datasets
in the McIDAS-XCD Administrator's Guide for more information. As also noted
there, you can optionally run the command BATCH XCDCONDUITGRID.BAT
to create ADDE datasets for the subset of CONDUIT LDM GRIB2 grids that the SSEC Data
Center provides for its users.
- The XCDNOAAPORTGRID.BAT and XCDCONDUITGRID.BAT files were first implemented in
McIDAS-XCD 2014.1; see the 2014.1 software and instructions page
for more information.
Restart LDM and then McIDAS-XCD by running the commands below in order at a Unix prompt as user
Type: sh ./xcd2017.2.sh install addeservers
Type: ldmadmin start
Type: xcdadmin start
This concludes the McIDAS-XCD Fastrack version 2017.2 installation procedure.
