Configuration

We recommend that the ProRad software is run by a dedicated UID, and we have chosen to install the software in the home directory of such a user. It may not be what your IT-department recommends, but as soon as you have familiarised yourself with the software you will know what to do to comply with rules and regulations of your organisation.

Once you have built the software, all modules will be present in the 'bin' directory in the directory where you built the software. You may copy these files to wherever you wish.

In the following example we assume you have a dedicated user for running the software, and that the software is installed in this users home directory.

Basic installation

We use the following setup for our installation. Each release of the software is kept in a directory, named after the release:

drwxr-xr-x 29 uid uid 4096 2012-03-02 13:20 prorad-xml-1.3
drwxr-xr-x 29 uid uid 4096 2012-03-14 14:49 prorad-xml-1.3.1
drwxr-xr-x 29 uid uid 4096 2012-03-20 08:54 prorad-xml-1.3.2
drwxr-xr-x 29 uid uid 4096 2012-06-21 10:18 prorad-xml-1.3.2.1

And we use a set of symlinks which can be quickly rearranged if we should detect problems and need to make a quick switch from one release to another:

lrwxrwxrwx  1 uid uid   18 2012-06-21 11:28 prorad -> prorad-xml-1.3.2.1

and then we use this link to setup the symlink to the bin directory

lrwxrwxrwx  1 uid uid   10 2012-01-16 10:06 bin -> prorad/bin

(This may seem a little counter intuitive, and it would be perfectly fine to just to point the bin symlink directly to the directory containing the current ProRad release. Again, this is how we do things. Feel free to deviate from this recommendation if you so wish.)

We also keep a similar structure for the configuration files

drwxr-xr-x  8 uid uid 4096 2012-02-09 12:36 config-xml-1.3
drwxr-xr-x  8 uid uid 4096 2012-03-19 15:17 config-xml-1.3.1
drwxr-xr-x  8 uid uid 4096 2012-03-20 09:41 config-xml-1.3.2

and here we aslo use a set of symlinks to point to various subdirectories within the configuration package

lrwxrwxrwx  1 uid uid   16 2012-03-29 16:26 prorad-config -> config-xml-1.3.2
lrwxrwxrwx  1 uid uid   17 2012-01-16 10:06 etc -> prorad-config/etc
lrwxrwxrwx  1 uid uid   21 2012-01-16 10:06 scripts -> prorad-config/scripts

Diretories for storing datasets

We have chosen to put the data files on a separate partition, and the directories listed here is a minimum configuration for a ProRad node performing volume filtering/QC, precipitation accumulations and making mosaics from 2D products

/disk1/proradfiles/
/disk1/proradfiles/permanent
/disk1/proradfiles/permanent/var-run
/disk1/proradfiles/permanent/foo-mask
/disk1/proradfiles/permanent/map-mask
/disk1/proradfiles/short-term
/disk1/proradfiles/short-term/reproj-files
/disk1/proradfiles/short-term/geotiff
/disk1/proradfiles/script-dirs
/disk1/proradfiles/script-dirs/images
/disk1/proradfiles/script-dirs/ftp-logs
/disk1/proradfiles/long-term
/disk1/proradfiles/long-term/mom-messages
/disk1/proradfiles/long-term/log4cxx
/disk1/proradfiles/long-term/prorad-acrr
/disk1/proradfiles/long-term/sched-acrr-filelists
/disk1/proradfiles/long-term/filtered-products
/disk1/proradfiles/long-term/mosaics
/disk1/proradfiles/long-term/prorad-import
/disk1/proradfiles/long-term/prodgen-products

We have chosen make a distinction between datasets that can easily be recreated and those datasets that require more work to regenerate. The former are stored in the 'short-term' directory, the latter are stored in the 'long-term' directory. There is also a category of files which belong in the 'permanent' directory, these include datasets related to beam block calculations (not shown here) and PID-lock files stored by each module to prevent multiple instances with identical configurations to be started.
